Which is better for central air conditioning air outlet material

Which is better for central air conditioning air outlet material?

The central air-conditioning is hidden in the United States. The air outlet is only left in the room and will not damage the home decoration. Then, when installing the central air-conditioning, what kind of air outlet material should be selected. Dezhou Yixing Air Conditioning Co., Ltd. Xiaobian below to tell you about the central air conditioning tuyere material which is better?

The central air-conditioning tuyere is the end device for air supply and return air in the central air-conditioning system. It is an air distribution device. The air outlet size of the central air-conditioning is required. The following Yixing air-conditioning small series will tell you in detail. Say it.

1. Dimensional standard of central air conditioning air outlet

The size of the air outlet depends on the size of the indoor unit. If the air outlet is too large and the air duct is too long, the airflow speed will decrease, which will affect the air conditioning effect. If the air outlet is too small, the airflow speed will become larger. As a result, the wind directly blows the discomfort caused by the human body, and may cause excessive noise.

2, the central air conditioning air outlet material classification:

There are three main types of air conditioning air outlets on the market. Aluminum alloy, wood material, ABS material, and three materials have their own lengths and lengths. Dezhou Yixing Air Conditioning Co., Ltd. introduces three materials for central air conditioning outlet. Length:

Aluminum alloy material: The air outlet of aluminum alloy material is cost-effective and moderately priced. Most central air-conditioning projects are air outlets made of aluminum alloy. It should be noted that in the summer cooling, the supply air temperature is too low, the insulation is not well done during construction, the air volume is too small, etc., the air outlet of the aluminum alloy material is prone to condensation, but the construction is strictly in accordance with the specifications. Happening.

Wood material: wooden material has beautiful and elegant air. It has a texture and can be matched with the overall wooden decoration style. The decoration is of high grade. The shortcoming is that when the air is heated in winter, the temperature difference is large and easy to deform. Cracking.

ABS material: ABS material is an emerging resin material with less deformation and condensation, and there are many colors to choose from. However, the price is more expensive, and the average family chooses less.

The above is the standard and material analysis of the air outlet of the central air conditioner. The three materials have different lengths and different cost performances. You can choose according to your own budget when you purchase.

Stamping Material and mold

The hardness of metal stamping parts is measured by Rockwell hardness tester. Small, complex-shaped stampings can be used to test small planes that cannot be tested on ordinary benchtop Rockwell hardness testers. The PHP series of portable surface Rockwell hardness testers are ideal for testing the hardness of these stamped parts. Alloy stampings are the most commonly used parts in metal processing and machine building. Stamping processing is a processing method in which a metal strip is separated or formed by a mold. Its application range is very broad.


Stamping parts processing includes punching, bending, drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel sheets, alloy steel sheets, spring steel sheets, galvanized sheets, tin-plated sheets, stainless steel sheets, copper and copper alloys. Plate, aluminum and aluminum alloy plates, etc.


1. Hardness testing of stamping materials


The main purpose of the hardness testing of stamping materials is to determine whether the degree of annealing of the purchased metal sheets is suitable for the subsequent stamping parts processing. Different types of stamping parts processing processes require sheets of different hardness levels. The aluminum alloy plate used for stamping processing can be tested by a Vickers hardness tester. When the material thickness is greater than 13 mm, the Barcol hardness tester can be used. The pure aluminum plate or the low hardness aluminum alloy plate should be a Barcol hardness tester.


2. Hardness testing of stamping parts


The main materials for stamping die are die steel (including tool steel and high speed steel), and sometimes hard alloy.


Stamping die is usually required to have high hardness and wear resistance, and heat treatment is indispensable.

Text can also achieve value, and writing articles can also bring orders

For writing articles and writing records, it is just a hobby, just like some people like to play the piano, some people like football, dancing… It’s that simple, without any private thoughts, this state of mind is The most enjoyable, the easiest to calm down, to do something with the heart.

For the writing of articles, records, in the age of technology, communication, and network development, it is no longer like the paper age, so it is rare to do this by writing to make money.

Now, all of them are based on hobbies and interests, write down the logs, and take notes. The right is to be used as a memory of their own way, just to show it to themselves. It is said that people must have a hobby and faith support. This is money and power can’t be changed.

When we have an interest of our own, no matter how hard life is, it can be regarded as a kind of psychological sustenance. When we go all the way, we all have to do our own thing, in the “fear of heart”, this How happy it is.

If there is no hobby that belongs to one’s heart, we are busy, and the heart is flustered like the one that is often transmitted online: “every day, mother, the key is not making money! How hard!” This is the state, and we will soon be out of balance. Therefore, I feel that there is a happiness in my faith that belongs to my hobbies. It’s not by writing to feed, it’s just a spiritual food, you can’t steal it!

I didn’t think I could write much before, but when I didn’t take it as a task, I only found it as a record, a log, an article, two articles, and many articles, one day, two days, and many days. As Lu Xun said: There is no way in the world, and there are people who have more to go. It may be like writing a record. The record book is not written. If you write more, you will have your own annual record.

Although the log is quiet there, there is no economic benefit, but sometimes when you are helpless or frustrated, you will have a different harvest to resonate and will take yourself out of this temporary dilemma.

But you said that writing an article record does not produce any value of interest, but what happened is a subversion of the traditional view of the value I bring to the text. I am doing the light. I used to do business. I didn’t send text messages, or send them in bulk. In short, I tried to add some potential customers, but the results were very small. After all, these strange customers are strange to us and it is difficult to get in. Their resistance to the world.

In the past, I will take the initiative to send QQ advertisements and Want Want advertisements, but the harvest is still very small. Some customers are even very disgusted, so there are very few orders that can be generated. It is said that this is an ultra-fast development, fast-growing society. In the past, the way to go door-to-door, find customers, and make a phone call one by one, this way of pulling business is getting harder and harder.

This traditional way, like the monster game upgrade game, wasted on the security guards with the gatekeeper to take up most of the time, fortunately passed to you, can not find a big boss, still a question. Even if you can find a big boss for you, how much you can convince them to order you.

So the world is changing, we are unchanged, and we may be changed. Slowly found a strange phenomenon, because often write log records, life, what to think, everyday. Some potential customers, strange customers, will slowly take the initiative to follow you and understand you. The result is that if they need this kind of light, they will come back to you. How amazing, I used to chase customers thousands of times, resisting thousands of times, but now it is looking for you.

I also think about what happened in the end. Some customers will say that through your article records, knowing your daily life, like a brand, establishes a cognitive value, from resistance to trust. This is either sharing articles and sharing the magical charm of the text.

Although I don’t deliberately cater to customers to write records, I feel that this is a change that I feel is very magical in my business. The text just happened to have the value of his interests. Although it is not deliberately created by myself, often, the trust of customers is yours. From here, the text is in it, the text is like a person. This is the charm of the text.

Business is going to the end of the day, but hobbies are never stopped. As a slogan says: As long as you know where to go, the world will make way for you! I hope that until the day I go, there will be a hobby that belongs to my heart.

As a child’s father, I have always insisted on making stories and telling stories for children. Although I feel that I have made a particularly bad compilation, it is especially magical. Children like to accompany you, come all the way, listen to stories, tell stories. Suddenly there is a whimsy. Although I have been making stories and telling stories to children, they are all improvised every day and have not been recorded.

Or you can record these stories and build up a lot. After a few years, make a story book for the grown-up children and tell them that their father and mother are telling these stories and accompanying you. . Will it be of great significance? Recording the story, recording the text, or letting the children feel that childhood is like this, there is a word record, there are traces to find!

These are the reasons why you are willing to write records, articles, and sharing, all the way! The charm of the transcript, the memory of the text, the happiness brought to us, the touch is beyond our imagination, so I am willing to keep this little hobby to go on!

Can the coffee table be equipped with a universal wheel

China is the hometown of tea and the birthplace of tea culture. Drinking tea has become a part of our lives. Whether it is a gathering of friends or a business meeting, we all like to treat guests with tea or even tea.

Drinking tea is also about the atmosphere of the mood. Since there is a good set of tea sets, the coffee table can of course not be less. With the continuous development of tea culture, the development of coffee table is also advancing with the times. Nowadays, many coffee tables can be moved. Installing the universal wheel at the bottom of the coffee table is not only convenient for cleaning, but also according to the number of people drinking tea. Different from the mood, change the environment to drink tea.

So what kind of universal wheel is suitable for the coffee table? What is the right diameter?

If it is a plate-type coffee table or a solid wood coffee table, it is more suitable to install a 1.5-inch flat-panel universal wheel or a 2-inch flat-plate universal wheel.

If it is a metal coffee table or a stainless steel coffee table, it is more suitable to install a 1.5-inch screw universal wheel or a 2-inch screw universal wheel.

Telemarketing: success is next time

One


It’s been almost a year since I arrived in Australia, and my English is still worse.


I am born with timidity, especially in front of a stranger who speaks blushing, which is very unfavorable for me to learn English quickly and to study and find a job. I am like an ant on a hot pot, eager to find a solution.


One day, I ate a newspaper at McDonald’s and found a call centre. During the interview, I learned that the call centre said that it is to communicate with customers on the phone every day to promote printer products.


The first two weeks of sales work are vocational training. We have a total of ten new salesmen, who paired each other, took the company’s prepared sales dialogue, and kept on the scene dialogue.


At the beginning of the actual battle, the call center was like boiled boiling water. Everyone yelled at the door, shouting at the microphone and flying on the keyboard. There is a big whiteboard in the call center, which is filled with the name of the salesperson, and there are various numbers behind it, which is no different from the scoreboards in the school.


two


The boss sent each of us five centimeters of thick paper, which was printed with names, company names, phone numbers, and addresses. We asked us to do market research to understand the demand for the printer and the brand. This is the first step in sales.


The first ice-breaking phone called out – “Beep, beep…” No one answered, I prayed, don’t pick up! Just at this time, a “hello” came in. I suddenly stunned, and before I practiced the dialogue, I suddenly disappeared without a trace. The voice of the other party was very thick. “hello, hello” snorted two times on the phone, silent, but did not hang up the phone, as if I knew that I was hesitant to talk.


How long is that long suffering… But think about it, is the next person like this, if the boss looks at me behind me? If he finds out that I didn’t say what I should say, am I going to roll out and leave? Regardless of him, anyway, the other party can’t see me, I take a breath and pull out a “hello”!


The phone is over, and I don’t know what to say. Although the voice of a rough man is not good, there is a question and answer. When I handed the data paper full of answers to the boss, the boss was happy to go with me high five (high-five), told the other seven people that I was the first person to get other people’s information… my confidence turned over Fan.


This is just the beginning. The real telemarketing is to take these data sheets and try to find the gold mines under the paper. A piece of data paper didn’t play, just next, didn’t dig up the gold, and then hit… just repeat the sales dialogue just mentioned.


three


A week has passed and ten people have gone four. I started to lose sleep, dreaming of sales dialogue.


The company’s policy is that if you fail to meet the standards for three months, you will have to pack things away. Sales is an important criterion for companies to check whether you have any use. The company does not have the money to raise you. Another is the percentage of calls: the more calls you make in a day, the better, the longer you say the better. No matter what you sell, as long as your mouth is always moving, the boss knows that you are working hard, maybe you can stay for a few more weeks. Otherwise, he will tell you directly, don’t come tomorrow.


Sales are so cruel. Seeing the end of the month, the sales volume behind my name on the whiteboard is still a big duck egg. I finally broke my hair. I picked up the phone data paper and beat it one by one. When I heard that the other person said that I was not interested, I asked what made you uninterested. When the other party repeats another interest, I am straightforward and hang up! next! After two days of anger, the eyes of God, finally let me catch a small school principal in a remote area, bought two boxes, worth 430 Australian dollars. That day, when I wrote the first sales figure, many people in the call centre applauded me… I slept very well that night.


After 20 days, I suffered a big fish after the hardships. When I wrote the number of 5000, the whole call center stood up. In addition to the applause, there were countless well done cheers, and some even ran over. I shake hands… The boss rewards me with a chocolate frog. That month, I got a $500 bonus.


really interesting. I practice speaking, don’t have to pay tuition, and take money. It is a bit mad, worthwhile. When I sell something, I know that my English is understandable, I understand others, and I can reach a consensus with the other company’s company. The generation of monetary benefits is the most direct result of a successful dialogue. Isn’t this more affordable than the TOEFL test?


I also received a sentence from the boss: It is normal to do ten business abortions nine times, but there is no strong will, not to try again and again, how do you know that there is no underground vault in the next data sheet?

Method of using wire seals

For many users who have used wire seals, it is known that the wire seals are disposable. As long as the wires are inserted into the lock cylinder, they cannot be withdrawn for anti-counterfeiting and anti-theft purposes. The internal principle of the tightened wire seal is actually very simple. The inside of the lock body is fixed to the lock body by one end of the lock band, and the other end of the lock band is connected with a lock head, and the lock body has a counterbore for the lock head to penetrate. The lock body has two inclined holes communicating with the counterbore, and each of the inclined holes is provided with a spring, and a steel ball is respectively arranged at the communication between the inclined holes and the counterbore, and the steel ball is supported by the corresponding spring, and the lock is locked There are two grooves on the head corresponding to the two steel balls respectively, and the front portions of the two steps forming the first groove near the front end of the lock have chamfers.

How to maintain the hardware of luxury bags

hen many people care for luxury bags, they only know how to maintain the skin. In fact, the hardware of the luxury bag is just as important. A piece of hardware can change the temperament and appearance of the whole bag. The following small series brings you the method of hardware maintenance, I hope to help you.

Metal maintenance of the bag

Metal parts are the highlight of the bag, and many styles of metal accessories are the finishing touch. Many MMs also rely on the observation of metal parts to judge the true and false of the bags. After all, it is less difficult to copy the leather. If the texture of the metal parts is the same, the engineering quantity can be large.

But unfortunately, even the metal parts of Hermes and LV are also synthetic metal plating and other processes, improper maintenance is prone to color loss, fading or even rust. After the bag has been used for a period of time, it is normal for the metal parts to wear, scratch, etc. Therefore, the key to maintaining the metal parts is how to delay the speed of wear and fading, and avoid the rust stains caused by surface wear.

The most common metal parts problem;

The zipper of a bag is often worn because it is often used, but generally does not rust. And the zipper is generally not exposed, it doesn’t matter if it wears a little. It should be noted that if the bag is exposed to rain or water on the zipper. Before the zipper is worn, because the coating on the top will not rust, after a period of use, the zipper wear coating will fall off and it may rust. If there is a slight rust, you can wipe it with a silver cloth (small reminder, use silver cloth to darken it, don’t wash it. It is useless to wash off the special coating on the outside.) If the zipper is wet, please Cover it with kitchen paper or a nice napkin and let it dry in a well-ventilated place (don’t expose it!). Cover the paper with the rust and fading in the process of drying, avoid getting the bag, remind you not to use the newspaper!!! The ink will stick to the bag.

Externally decorated metal parts, such as LV small locks, DIOR metal LOGO, etc., a soft cloth is often wiped, try to avoid hitting hard things in daily use. It is best to wrap the metal parts with an electrostatic film, which is dustproof and waterproof. Pay attention to the electrostatic film. Do not use sticky things such as rubber strips. Most of the strips are corrosive and not easy to tear off.

In addition, the handles of some bags are also connected by metal parts. These parts are also frequently active and wear out, so the key to maintenance is to keep them from rusting. However, unlike zippers, these parts are generally linked to the skin. It is possible that the fading of the metal parts is dyed on the skin, that is, “cross-color”. The occurrence of cross-color in normal use cannot be avoided. During the preservation process, care should be taken to place the moving parts in a reasonable position to avoid contact with the leather.

Power head and tool changing mechanism of CNC machining center

With the continuous development of science and technology, the quality and productivity of mechanical products are increasingly demanded, all of which rely on the further improvement of mechanical and technological. Automation of machining process is one of the most important measures to achieve the above requirements. The so-called machining is to process metal blank parts into the desired shape, including two aspects of dimensional accuracy and geometric accuracy. Can complete the above functions of the equipment are called machine tools, CNC machine tools is the development of ordinary machine tools, CNC means digital control. After the CNC system is installed on the machine tool, the machine tool becomes a numerical control machine tool. Digital control machine tool refers to the information in the form of digital code (program instructions), control tool according to a given working procedure, speed and locus for automatic machining machine tools. Generally speaking, CNC equipment mainly refers to CNC machine tools and machining centers. NC machining center is a highly integrated Mechatronics product. It adds tool depot and automatic tool changer to the original NC machine tool. It makes full use of the continuous development of computer control technology and other and many advanced precision machinery and automatic control systems.

machining center

In 1948, Parsons Corp. of the United States accepted the Commission of the United States Air Force, the development of aircraft propeller blade profile template processing equipment. Because of the complex shape and high precision of the prototype, it is difficult for the general processing equipment to adapt, so the idea of computer control machine tool is put forward. In 1949, with the assistance of the MIT Servo Research Laboratory, the company began to study CNC machine tools. In 1952, it successfully developed the first three-axis CNC milling machine modified from a large vertical profiling milling machine. It soon began production and was officially put into use in 1957. This is a major breakthrough in the development of manufacturing technology, marking the beginning of the era of NC machining in the manufacturing field. NC machining is the foundation of modern manufacturing technology. This invention has epoch-making significance and far-reaching impact on the manufacturing industry.

Vertical machining center

During the Eleventh Five-Year Plan period, with the breakthrough of a series of key technologies and the formation of independent production capacity, China began to highlight the “heavy encirclement” of “foreign-made” and entered the ranks of the world’s high-speed CNC machine tools and high-precision CNC machine tools producers. Under the pull of demand, the output of CNC machine tools in China maintained a high-speed growth, with an annual compound growth rate of 37.4%. In 2010, China’s CNC machine tool output reached 236,000, an increase of 62.2%; in 2010, China’s CNC machine tool consumption exceeded 6 billion U.S. dollars, more than 100,000 sets, CNC machine tools have become the mainstream of machine tool consumption. Since 2009, the continuous investment in the major scientific and technological projects of “high-grade CNC machine tools and basic manufacturing equipment” shows the government’s determination to develop high-grade CNC machine tools and basic manufacturing equipment. During the Twelfth Five-Year Plan period, China will continue to invest, and increase its efforts. Major special projects will lead to investment of more than 10 billion yuan annually.

Small CNC milling machine

Looking forward to the 12th Five-Year Plan, the development of China’s CNC machine tools will strive to solve the problems of large but not strong mainframe, lagging development of CNC systems and functional components, large gap in key technologies of high-grade CNC machine tools, low product quality stability, poor overall economic benefits of the industry and so on, and will cultivate core competitiveness, independent innovation, quantitative integration. And brand building to a strategic height, achieving the target of 800 billion yuan of total industrial output value. We will strive to achieve a series of medium and long-term goals, such as the transformation from a big machine tool producer to a powerful machine tool producer, and the realization of the dominant position of domestic medium and high-grade CNC machine tools in the domestic market. The development of computer control technology and other and many advanced precision machinery and automation control system composition.

Is stamping as punch

1. Stamping is a method of forming and processing workpiece (stamping piece) with required shape and size by applying external force to sheet, strip, pipe and profile by press and die. Stamping and forging belong to plastic processing (or pressure machining). The stamping blanks are mainly hot rolled and cold-rolled steel plates and steel strips. 60 to 70% of the steel products in the world are sheets, most of which are stamped into finished products. The car body, chassis, fuel tank, radiator fin, boiler drum, container shell, electrical machinery, electrical core silicon steel sheet, etc. are stamped. Instruments, household appliances, bicycles, office machinery, household utensils and other products, there are also a large number of stamping parts.


Stamping is a kind of production technology that can make the sheet metal be directly deformed and deformed in the die by the power of conventional or special stamping equipment, so as to obtain a certain shape, size and performance of product parts. Sheet metal, mold and equipment are the three elements of stamping process. According to the stamping temperature, it can be divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity, while the latter is carried out at room temperature, which is a common stamping method for sheet metal. It is one of the main methods of metal plastic processing (or pressure processing), also belongs to the material forming engineering technology.


The die used for stamping is called stamping die, or die. Punching die is a special tool for batch processing material (metal or non-metal) into the required stamping parts. The punching die is very important in stamping. Without the punching die that meets the requirements, the batch stamping production will be difficult; without the advanced punching die, the advanced stamping process will not be realized. Stamping process and die, stamping equipment and stamping materials constitute the three elements of stamping processing, and only when they are combined can stamping parts be obtained.


2, punch press is a punch press. In the national production, stamping process is more and more widely used because it has the advantages of saving materials and energy, high efficiency, low technical requirements for operators and can make products that can not be achieved by machining through various die applications.


Stamping production is mainly aimed at sheet metal. Through the mold, can be blanking, punching, forming, drawing, dressing, fine punching, shaping, riveting and extrusion parts, and so on, widely used in various fields. For example, we use switches and sockets, cups, cupboards, saucers, computer boxes, even missile planes. There are a lot of accessories that can be produced by punching machines through molds.

Industry characteristics of machinery industry

From the analysis of the situation of the machinery industry, the growth rate of hand-held orders is not low, it is not expected that there will be a big ups and downs in production problems. In the second half of this year, the economic operation of machinery industry continued to grow steadily. Total industrial output value, industrial added value, main business income, total profit and foreign trade export volume will maintain a relatively high growth rate of about 25%.

Starting from the characteristics of production, we can see that the mechanical manufacturing industry has the main characteristics of discrete-based, process-assisted, assembly-focused. Taking equipment manufacturing as an example, the mode of production is generally composed of individual parts and final products, which is a typical discrete industry. Although the automobile manufacturing industry, such as die casting, surface treatment and other processes belong to the category of process, but most of the process is still characterized by discrete. Based on the above industry characteristics, the machinery industry has the following characteristics in the course of production and operation.

1, the production planning and production tasks management tasks are arduous.

Typical discrete machinery manufacturing enterprises are mainly engaged in single-piece and small-batch production, and the process of products is often changed. It is difficult to predict when the order will arrive because the production is mainly organized according to the order. Therefore, a good production planning system is needed for the purchase and production workshop planning.

2, the level of automation is relatively low.

Because of discrete processing, the quality and productivity of products depend largely on the technical level of workers. Automation is mainly at the unit level, such as CNC machine tools, flexible manufacturing systems and so on.

3, the process is simple and clear, the process is flexible, and the coordination of manufacturing resources is difficult.

The product structure of machinery industry is clear and definite. The product structure of a mechanical manufacturing enterprise can be described by the concept of number. The final product must be composed of fixed number of parts or components. These relations are very clear and fixed. Order oriented machinery manufacturing industry is characterized by multiple varieties and small batch. Therefore, the layout of production equipment in the machinery manufacturing industry is generally not according to the product but according to the process, the process of each product may be different, and there are more than one machine tool that can carry out the same processing technology. Therefore, it is necessary to schedule the processed materials, and intermediate goods need to be transported.
