Basic structure of aluminum box

A splints: fierce competition, some of the counterparts to reduce the price of the box to reduce the use of materials that do not meet the design requirements, such as the use of 8mm to replace the 9mm splint, and even some of the worse board (MDF, large core plate), so that the box will be swollen after wet, so that it can not be used normally.
B aluminum: aluminum is also thick and thin, aluminum is the skeleton of the box, the degree of thickness in addition to the appearance of the box in addition to the aesthetic sense, more important is when the box to bear the impact of external force, to maintain the stability of the box. Aluminum must be used for the use of oxidized aluminum, because there is no aluminum in the oxidation process. As long as it is placed for a period of time, it will naturally oxidize and be dumb, which directly affects the beauty of the box.
C Hardware: the structure of the hardware, the thickness of the material has a direct influence on the use time of the box. Many manufacturers or users like to use the hardware products of plating, because it looks beautiful for a short time, but when the products are actually used, the plating will be easily damaged and rust after the damage; and galvanized. Although the appearance of the hardware is ordinary, it can automatically release the decomposed protective layer and prevent damage, so as to achieve a good anti rust effect.
D shock proof layer: the high density (EVA glue) and pearl cotton in the box, the density, hardness and thickness of these two kinds of cotton determines the protection and the degree of shock resistance to the loaded articles; the three parameters must be moderate, the density and the hardness are too high, which will affect the shock resistance; too low, easy to sag and affect the service life.
The last part of F is the most important part of the wheel. There are many kinds of wheels. There are PVC wheels, PU wheels, load wheels and so on. And according to the other parameters of the wheel, such as single bearing, double bearing, single brake, double brakes, steel thickening, the high and low temperature and weight can be borne; the price varies from a few to dozens of pieces of one and one wheel. Good or bad directly determines the normal transportation, placement and use time of the box.

Mixing with liquid, solid and liquid materials, reaction, dispersion, dissolution, homogenization, emulsification and so on.

2 working principle
The viscous mixer is equipped with a low speed mixing unit and high speed dispersing component. The low-speed mixing unit uses a planetary gear drive, and the agitator also rotates during the rotation, making the material moving up and down and around, thus achieving the ideal mixing effect in a shorter time.
The high-speed dispersive parts are rotating together with the planetary frame, and the high-speed self rotation makes the material be mixed with strong shearing and dispersing. The effect is several times of the ordinary mixer. The dispersive parts are divided into single dispersing axis and double dispersed axis, and the customers can choose according to the needs.
Two double frame agitators rotate at the same time and rotate at the same time. Vacuum pumping, heating and cooling can be realized. According to the conditions, the speed regulation can be realized. It can be operated with multiple agitators with more than 1 machines.

3 performance characteristics
The performance of the double planet mixer is characterized by that the tank can be heated by electricity, steam, water and oil. The special temperature detection device on the transmission shaft ensures that the temperature error of the material is less than 1. The jacket, the bottom jacket and the jacket inner tube and the guide plate can be cooled. The rotating and self rotation of the mixing pulp in the tank can be variable frequency motor (frequency conversion motor), and the different rotational speeds can be selected according to different processes and different viscosity. The speed measuring system directly gives the speed of different agitators at that time.
1. the mechanical seal and the trapezoidal soft seal between the kettle body, so that the material can be operated in vacuum.
2. the kettle body can be heated by electricity, steam, water and oil. The unique temperature detector on the transmission shaft ensures that the material temperature error is less than 1 degrees. The jacket, bottom jacket and jacket inner tube and guide plate can realize cooling.
The inner wall of the 3. cauldron is a large vertical lathe, and then it is automatically polished by a large polishing machine to ensure that the movable scraper on the planet rack (suitable for sealant) is completely scraped away from the inner wall of the body of the cauldron when it is rotated.
The 4. cauldron frame type (paddle and paddle, pitch and wall spacing 3-4mm) stirred oars (multiple blades), and rotate at the same time, so that the material flows down and around, thus the effect of mixing (mixing) can be achieved in a very short time.
5. the mixing and rotation of mixing slurry in the kettle are controlled by frequency conversion (frequency conversion motor), and different speeds can be selected according to different processes and viscosity. The speed measuring system directly gives the speed of different agitators at that time.

How to look at the effect of a hot air blower

When buying industrial hot air machines, the performance of the hot air blower should be understood clearly, but the manual of the hot air machine is generally complex data composition is not easy to understand, so let us give you a brief introduction:

First, it is necessary to choose hot air blower and know that it is a kind of heat sink, so the exhaust equipment of hot air fan must be checked well.

For a new hot air fan, the general air volume is very large, and this exhaust volume is also a certain parameter, in fact, in the purchase, it will also give you some parameters of the hot air machine, indicating that the parameters for the work is also very important on the one side, the volume of wind is based on the unit area. Within this range, if the fan is able to emit a greater wind, the fan will be better.

Second, this problem will be noticed when choosing all electrical appliances. The hot air fan is also a charged device.

In this case, there is voltage and current, so there is power, so power is also an important factor affecting the efficiency of the hot air blower. Power is only one aspect of the hot blower, but not the greater the power of the fan is the best, and more, the effect of the fan will be determined by its exhaust air volume.

Third, we know that the most important feature of the hot air blower is to regulate the temperature, and temperature is one of the important problems that we should pay attention to.

Many hot air machines are only a heater, but not the function of refrigeration, so these hot air machines should pay attention to the problem of cooling. If the cooling effect of the hot air blower is not good, then it may burn the machine, cause the machine to not run normally, the hot fan factory in the market, in order to have good sales, a lot of all The function of the hot air blower is exaggerated. It says it has a good cooling function. If we have a great demand for the hot air blower, we must check the equipment of the hot air blower in person.

The hot air machine is a heating equipment, but some people are too keen on the diversification of the function and do not pay attention to its basic function, so that the main function of the hot fan can not be placed on the important position, so a good hot air machine should also see whether the heating effect is good or not.

What are the functions of cloth bag ash remover used in industrial boilers

What are the factors and functions of the cloth bag deduster used by industrial boilers? In today’s social production, our country has been advocating the spirit of environmental protection and environmental protection. The application of the bag dust collector is becoming more and more extensive in the present time. The dust in our life is kept in all the time. If we want to control the dust, it will be necessary. Use bag filter, so why do industrial boilers need to use cloth bag duster? Below, I would like to introduce to you why industrial boiler uses dust remover.
Because the industrial boiler in our country mainly uses coal as fuel, it will produce a lot of smoke and dust in the operation of the boiler. The exhaust dust will cause serious pollution to the environment. The main function of the industrial dust collector is to collect the dust and dust caused by the pollution to the environment and avoid the emission. In the middle of the atmosphere. Thus protecting our living environment, so this is why industrial boilers use dust remover.
The boiler bag filter is also called the filter type dust collector. It is a dry and efficient dust collector. It is a bag filter element made of the fabric of fiber to collect the dust removal device of solid particles in the dust gas.
The function principle of boiler bag dust collector
Dust particles are intercepted by the impact of inertia force on fibers when they pass through filter cloth fibers. Fine particles (the particle size of 1 microns or smaller) are affected by the impact of gas molecules (Brown movement) constantly changing the direction of motion. As the gap between the fibers is smaller than the free path of the gas molecule Brown movement, the particles are separated from the fibers in contact with the fibers. The working process is related to the weave method of the filter material, the density of the fiber and the diffusion of dust, the inertia, the shielding, the gravity and the electrostatic action, as well as the cleaning method. Filter cloth is the key to the bag filter, and the filter cloth with good performance should have good corrosion resistance, heat resistance and high mechanical strength in addition to specific density and air permeability. The heat resistance of the fibers has reached 250 – 350 degrees Celsius.
Undefined
Dust removal method of boiler bag dust collector
The boiler bag filter can be divided into five types: vibration type, gas ring reverse blow type, pulse type, acoustic type and compound type according to their cleaning methods. According to the difference of back blow air pressure, pulse back blow type can be divided into two types: high voltage pulse backward blow and low voltage pulse reverse blow. The pulse cleaning bag filter can be adjusted because of its pulse intensity and frequency. The dust cleaning effect is good. It is the most widely used dust removal device in the world at present.
What are the factors and functions of the cloth bag ash remover used in industrial boilers? More information about the product knowledge of the boiler bag dust catcher can contact us.

Environmental protection knowledge of environmental protection in the new rural area

Basic introduction
Before installation of the dung truck, the pump is installed under the car beam with the appropriate rack, angle iron and hoop. The position of the pump is high and low, around and before and after. The axle center line is determined by the output shaft of the force collector. It is as close as possible to the force and beam under the condition that the parts of the car beam are not interfered. The connection between the pump shaft and the output shaft of the take-off device should not be greater than 7 degrees.
The suction pipe system is strictly prohibited from leakage, otherwise the vacuum degree will be affected. The exhaust pipe should also leak out so as to avoid vacuum oil discharge, pollute the environment and waste energy.
Because this pump is oil seal pump, it is necessary to maintain sufficient N32 mechanical oil in normal movement. The northeast and northwest regions should use No. 32 frozen oil in cold winter season. The oil will be sealed clearance and lubrication, but the oil in the pump will be taken out of the pump when the exhaust is exhaust. Therefore, the first and two stage oil and gas separator must be installed on the outside of the exhaust port to make the oil and gas separate fully, the oil recovery is resupplied to the pump, and the gas is discharged into the atmosphere to make the pump run smoothly to no pollution and energy saving.
Matters needing attention
Proper installation of vacuum suction pump for suction dung cart and matters needing attention in use and maintenance:
1, the pipeline is not allowed to leak phenomenon, otherwise the suction cart will not be able to work.
2, suction dung cart barrel must be installed with anti overflow device. Otherwise, when the suction cart is used, it is easy to suck the fecal sewage into the vacuum pump and damage the whole system.
3. Connecting the oil and gas separator of the first grade gas separator to the two stage oil and gas separator and the oil suction pipe must be used with hard pipe or hard oil resistant rubber tube (steel wire woven hose), and the plastic pipe with hot deformation is not allowed.
4, when the suction truck is used in the new pump, 1-2 liters of N32 mechanical oil should be added directly to the pump. The number 32 refrigerant oil should be added to the northeast and northwest cold regions.
The water gas separator should be added at the pump suction port.
There are first and two class oil and gas separator, four way valve, water and gas separator with one-way valve and overflow prevention device.

Years will not live up to every person who is optimistic.

On Saturday, the sun was extraordinarily full, but my heart was upset because of the recent accounts of the company. I used to spend time reading or codeword in the past. These days were flashing, nagging, harsh words, and at last triggered a war between husband and wife.
I arranged my mood and sent my daughter to Chinese painting class.
Along the way, the breeze is warm and the sun is shining. The warm light can not drive away the thick heart haze.
At the Academy, the calligraphy class had not been dismissed yet, and the waiting space, a bookmark wall in the corridor, attracted me all of a sudden.
A bookmark with elegant colors is pasted up by a caring teacher and arranged in an interesting and unique style. The bottom of each bookmark falls up with tassels. From afar, it looks like a series of colorful wind bells, dancing with the breeze.
Taking her daughter closer to see it, I saw this text.
“When you can’t tell yourself what you learned today, don’t go to bed!”
“Those who are lying in bed do not feel the warmth of the sun.”
“I want to paint in addition to the pen, but also the intention, you are a caring child, dare to show your potential!”
Each of them was accompanied by a little friend’s sketches, some small people, some of the outline of the park, some flowers and flowers, and the paintings of the parents, expressing the love and intimacy of the children to their parents.
Each is filled with deep meaning and childlike interest. The cold heart suddenly feels like a hit, and feels warm and soft instantly.
Those young times, like the inverted disk, at that moment, were instantly recovered.
Sometimes adult beliefs are not as good as a child’s determination and persistence.
When the company was just registered, we had made such a great ambition that we had a good prospect, and even though we knew that the wealth needed to be accumulated, we still had the unrealistic expectation and vision.
Everyone will meet the twists and turns, life is a kind of experience, the vicissitudes of time is a accumulation, the suffering this double-edged sword, to bring us pain at the same time, but also let us grow in the mud.
All the success of the world, the bright road they treadle, not many times and perseverance in the past, so, no need to envy, everyone in the uphill road of life should go, do not want to fall into a mediocre, it will be more frustrated and more brave.

In the movie “happiness knocks on the door”, the father, Chris, relies on selling medical equipment to maintain a family’s life, but a series of changes make him trapped in life, his wife abandons him, the child is not taken care of, and then the house is bombarded because of the rent.
As he hovered the young son with the medical instrument in one hand and hovering in the subway, he laid the newspaper in the bathroom to let the child snuggle up to him and his clothes, and the child asked, “Daddy, why should we live here?” When someone pushed the door outside, he used his body to hold the door, and covered his son’s ears with those big hands. The strong and stubborn father had shed bitter tears.
This is not the worst. Every day they go to the relief station to wait in line, hoping for a night’s shelter, but this is a great expectation.
The encounter with stockbrokers of securities companies opened another door to life for him. Chris learned that the famous stock investment company had an opportunity for an internship, but there was no salary during the internship, and the competition was fierce, and only one person was able to enter the company. Through hard work, he finally won the only chance.
No matter how difficult and unbearable life is, he did not complain about life, nor did he give up his dream. On the pitch, he once said this to his son.
“Don’t let anyone tell you that you can’t do something, not even me.”
“If you have a dream, you have to guard it.”
“When people can’t do something, they will tell you that you can’t do it. If you have ideals, you have to work hard to achieve them.”
And is this kind of teaching the best interpretation of himself?
This movie is an autobiography by Chris, and also a legendary inspirational story. The story of how he struggled from the black slums, trying hard, and eventually entering the securities industry, becoming an excellent securities investor, and successful business.
We always think there will be no tomorrow, but as long as we do not give up, we can always encounter the turning of the peak, and then the dark night will always endure until the dawn.

Think of a big sister I used to admire. After a failed marriage, she had two children to maintain her husband’s legacy, and a pile of debts and starving children often forced her to go mad at night.
She thought about escaping and thinking of leaving, but could she really escape conscience from all her life?
At the same time, it was difficult for the children to be accompanied and bitter. When they came back home and saw the cheering of the children coming to her, she felt that all the pay was worth it. She taught the child what responsibility and responsibility with her actions and beliefs.
In the family that lacks the role of father, the children are more sensible and angry, and the family is so happy and happy when two of their brothers and sisters present the full mark in front of their mothers.

What is the ball maintainer type guide

The ball retainer type LM rolling guide has the structure that the steel ball is kept through the ball holder to circulate. Therefore, the friction between the steel balls is eliminated, so that the steel balls can be evenly spaced to carry out the movement.
Moreover, the grease accumulated in the space between the steel ball cycle part and the ball holder (the grease storage space) will water the rotation of the steel ball to the contact surface between the ball and the holder of the ball, so that the oil film will travel on the surface of the steel ball. Therefore, the oil film is not easy to break up.
The effect of the ball holder
1. Due to the no friction between the steel balls and the improvement of the oil retention, the long service life and long term operation without maintenance (long term maintenance for lubrication) are realized.
2, there is no collision between the steel balls, so as to achieve low noise and good sound quality.
3, there is no friction between the steel balls, and the calorific value is low, thus achieving excellent high speed.
4, steel balls are evenly spaced to circulate, thus ensuring smooth operation.
5, there is no friction between the steel balls, so that the steel balls will not wear, and the grease will not be easily dispersed, thus reducing the dust generation.
