What do you need to pay attention to the installation of the electromagnetic furnace? Hot pot electromagnetic furnace table maintenance skills should be from the following aspects, the tempered glass has heat-resistant, wear-resistant, resistance, impact resistance, easy to clean up, crystal transparent and other characteristics, more and more people have been sent.
1., if there are decorative glass, you can use a toothbrush with a cleaner and an induction cooker to install. What should we pay attention to? Wipe off its stains. Because the seams are easy to crack, the shrinkage and deformation of the substrate will be caused. Prevent insolation, rain and rain.
2. hypothesis found that there are mildew, should be moved to the ventilation, and in the middle of the mildew in the center for 2-3 minutes, until the mildew fade away; to keep clean, must avoid pollution and produce mildew.
3. about tea and so on to the table, the electromagnetic oven installation need to pay attention to what? You can sprinkle some water on the table, wipe it with tin foil in the cigarette box, wash it with water and wash it off. It should be dry in time, otherwise, the time will leave a very ugly piece of film stains. Suppose there is a stain.
4. in daily cleaning, if the stain can be dipped in a towel with a towel or warm vinegar, wiped with a wet towel or newspaper, the surface of the glass is easily frosted in winter. It can be wiped with a cloth or white liquor. The effect is very good. In addition, it can also use the glass cleaning agent sold in the market, and avoid using the strong acid and alkali solution to clean.
5. in order to avoid scratching the glass surface, what should we pay attention to when installing the induction cooker? It’s better to lay the tablecloth on the platform. Always remember not to force the glass surface. When placing something on top, gently handle it.
6. if the coke marks only in the appearance, can be wrapped in a hard cloth on the toothpick to wipe the mark quietly, then coating a layer of wax, coke mark can be removed. In fact, the table chair is not necessary to take care of the table and chair, the electromagnetic furnace installation needs to pay attention to what? The greatest secret is to use it every day. The things you don’t use are always compared to the old and damaged. It only needs to be used frequently. The more it is used, the more it is consolidated, and the baby is valuable only when it is used. Prevent the burning of cigarettes, otherwise the scorch will be left.
7. first, the glass spray on the cleaning agent, and then paste the fresh-keeping film, so that the solidified oil stains softened, after a very long clock, tearing off the plastic film, and then wiped with wet cloth. What do you need to pay attention to the installation of the electromagnetic furnace? To stick to the bright bright glass, it is necessary to clean the glass regularly. If there is a handwriting on the glass, it can be rubbed with rubber soaking and then wiped with wet cloth; if there is a paint on the glass, the cotton can be dipped in hot vinegar, and the glass is wiped with clean dry cloth, and it can be as bright as crystal. The use of fresh-keeping film and wet cloth sprayed with detergent can also restore the oily glass.
What should be paid attention to the installation of the electromagnetic furnace
Single arm hydraulic machine should pay attention to inspection and maintenance for a long time.
Single arm hydraulic press is mainly applied to the technology of drawing, forming and pressing of metal products, processing non metal materials, pressing of powder metallurgy products, correction of shaft parts, pressing of sleeve parts and shaping and cutting edge of metal products. The use of a long time will inevitably appear such or such a fault, so in daily use, we should pay attention to the single arm hydraulic press inspection and maintenance.
Single arm hydraulic press can avoid air entering the hydraulic system in the hydraulic system. Once the air inadvertently enters the hydraulic system of the hydraulic press, it will cause the excessive noise or the oxidative deterioration of the contact between the hydraulic oil and the air, in addition to taking some air into the hydraulic system in daily work. In addition to the measures, check whether there is air in the hydraulic system, if any, it should be eliminated in time.
The hydraulic oil in the hydraulic system of a single arm hydraulic press must be kept crystal clear. Do not cause any impurities in the hydraulic oil. Because these impurities can easily plug gaps or throttle holes, the hydraulic system can not work normally, and can also speed up the parts in the wear hydraulic system. Therefore, in addition to the installation of the devices that obstruct the external impurities into the hydraulic system, the hydraulic oil in the hydraulic system should be replaced or filtered regularly.
In the long term use of a single arm hydraulic press to avoid leakage of the hydraulic press, but here it is worth saying that, if the internal leakage, although the leakage of this situation is unavoidable, but there is a certain amount of internal leakage, if the leakage of excess, then the pressure in the hydraulic system will lead to pressure. Not enough, causing internal movement instability. Leakage should be avoided. Proper sealing devices should be installed on the single arm hydraulic press, and the device should be inspected regularly.
It’s the best time to start now
Last Sunday, I met an acquaintance when I was shopping. 10 years ago, she opened the typewriter copying shop just next door to my shop.
I looked at her up and down. The more than 40 year old woman looked very intelligent. She told me that she was working in a famous company in the city, and became a department director not long ago.
10 years ago, she was going to run a copy shop outside. She went home to do housework and tutor the son of primary school. But every day, she took up books, read a few pages and made several questions. I was surprised that she was preparing for the adult college entrance examination. She was already more than 30 years old. Is it too late? When you get a certificate of completion, it’s the age of 40. Besides, her small business is good. Her husband has a steady income. Is it necessary to spell it?
She said that the age of adult college entrance examination is a bit too big now. In fact, she wanted to register two years ago when she hesitated because of her age. In the past two years, now I wonder if I had made up my mind to achieve the goal two years ahead of time.
So, she decided to start from now. She didn’t want to wait two years and go back again.
Later, she passed the adult college entrance examination. With the opening of more and more copies, the business in her shop gradually became desolate. At the same time, middle-aged women play mahjong watching TV and go shopping. She is trying to improve her ability. At the age of ease, she had no choice.
Later, she closed the shop and started a new life. When she met her again, she was head of the Department of a large enterprise. Now, think back to it. It’s not too late to get a certificate of graduation at the age of more than 30 when you take part in the adult college entrance examination at the age of 40.

I know a friend who was hooked on dancing at the age of 37. She wants to go to the dance class, all around the voice of opposition, everyone is asking her: the best age to learn the dance you have missed, your ligament still pull open? Is the action done well? In the face of questioning, she wanted to give up.
One time, she met a 58 year old sister in the dance classroom. She had been learning and dancing for 3 years. The dance skills were better than the teenage girls. She opened her mouth in surprise.
The elder sister told her that when she first learned the dance, she was also opposed by the family, and even some people said she was not afraid of disgrace. Old arms and old legs had also learned the fashion of young people. But she felt that now that she wants to learn, that is the best arrangement. It only takes more time than others to sweat more. How can I be reconciled to what I want to do without trying?
My friend decided to sign up to learn dancing that day. A few years later, she led the dance performance team in the provincial contest won the two prize.
It’s never too late to have anything. From now on, it’s the best time.

I started writing when I was nearly 40 years old. At the time, I lamented that I started too late and regretted the wasted time.
I learned about Jiang Shumei on the Internet. She started learning to write at the age of 60, and began writing at the age of 75. Now four works have been published. Like many traditional women, she gave birth to her child’s whole life. She didn’t begin to do what she liked until the child’s adult and her wife passed away. Who can think of an old man who begins to read at the age of 60 and will become a writer in the future?
Mose, the famous grandmother, began painting at the age of 76, and at the age of 80 he held a personal exhibition. He created over 1600 works and warmed many people. She told people: don’t make excuses for yourself. It’s never too late to do what you want to do, even if you are 80 years old.
Grandma Mose once wrote such a saying: someone always said it was late. In fact, it’s the best time now. For a real pursuer, every period of life is young and timely.
Four
It’s never our age, but our attitude towards age. We always thought it was too late, but it was in this lament that we missed the opportunity again.
But later we found it was not too late when we thought it was late. If from now on, the present oneself has already obtained, therefore, regretted once again regretted.
There is a good saying: age is never the limit unless you bring it to yourself.
For the time that has been wasted, regrets have no meaning, it is better to start from now on, ten or twenty years later, you will be grateful to yourself now that you still choose to start at the best of age, otherwise life is really only a pity.
Application range and working principle of brake motor
With the development of the times and the progress of science and technology, the brake motors have high precision positioning requirements. As the brake motor should have: fast brake, accurate positioning, safe and reliable, the brake system can be used interchangeably, the structure is simple, easy to replace maintenance and so on. Many factories need brake motors to control the inertia of motors, so as to achieve accurate positioning of the requirements, so as to realize the automatic operation of machinery.
Such as: lifting machinery, ceramic printing machinery, painting machinery, leather machinery and so on. Brake motors are widely used and can be seen in all fields of machinery and equipment.
In the rear of the motor, there is an electromagnetic brake. When the motor is electrified, it is also connected by electricity. At this time it does not brake the motor. When the motor is broken, it is also cut off and brake the motor under the action of the spring.
The two lines are the two AC input terminal of a full bridge rectifier and connected to the motor at the end of any two line of the motor to synchronize with the motor for the exchange of 380 volts, and the two DC output receives the brake excitation coil. The principle of the work is that when the motor is electrified, the coil has to produce a suction force to separate the two friction surfaces of the tail, and the motor is rotated freely, and conversely, the motor can be brake by the spring recovery force. According to the different motor power, the coil resistance is between tens and hundreds of euro.

Main parts of electric welding machine
The main component of the electric welding machine is a step-down transformer. The two ends of the secondary coil are welded and welding rods. The arc is ignited when working, and the electrode is fused to the slot in the high temperature of the arc. Because the iron core of the welding transformer has its own characteristics, it has the characteristic of sharp drop of voltage, that is, the voltage drops after the electrode is ignited, and the voltage drops sharply when the electrode is short circuited by adhesion. In the welding operation, although the current in the circuit is equal everywhere, but because of the different resistance, the maximum resistance at the unfixed contact is the contact resistance, according to the law of the thermal effect of the current (also called the jar’s law), that is, Q=IR.t can know that the higher the resistance is, the higher the heat is in the current phase. So when welding, the contact of the electrode is the most contact resistance at the contact of the metal body, and the electric heating is the most natural in this area, and the welding rod is the alloy with low melting point, and it is easy to melt. After melting, the alloy welding rod is bonded to the welded object, and then the welding object is bonded to one piece after cooling.
The difference between the full heat exchanger and the sensible heat exchanger
At present, there are two new fans with heat exchange functions on the market, one is the full heat exchanger and the other is a heat exchanger. The former is usually “paper” in the former, and the latter is usually aluminum. So there is no aluminum heat exchanger in the world. The general name of the aluminum core is the heat exchanger.
So what are the advantages and disadvantages of the two?
First, we look at the essence of them.
The total heat exchanger is commonly referred to as ERV, the full name is Energy Recovery Ventilation, and is translated into energy recovery ventilation.
The sensible heat exchanger is commonly referred to as HRV, the full name is Heat Recovery Ventilation, and the translation is heat recovery ventilation equipment.
The energy in the air includes the sensible heat (temperature) and the latent heat (humidity), and it is obvious that the total heat exchanger can reclaim the energy as a whole, and that the heat exchanger can only be part of the temperature, which is the essential difference between them.
Therefore, from the energy saving effect, the heat exchanger is not as good as the full heat exchanger, in other words, the popular point, the energy saving effect of the aluminium core new fan is not as good as the paper core new fan.
(2) from the actual installation and Application
There is a concept of “dew point” in the air, that is to say that the surface of the object will be exposed in a certain temperature and humidity state, which is reflected in the new fan. The surface of the so-called object is the surface of the heat exchange core, and the temperature of the heat exchange core will change because the new wind machine is to exchange the indoor and outdoor air. The greater the temperature difference, the higher the risk of condensation. And because the sensible heat exchanger can not adjust the humidity, the risk of condensation is much higher than that of the total heat exchanger. All sensible heat exchangers will be equipped with “draft tube”, because in general, the rate of condensation and frost will probably occur.
The function of the draft tube is to guide the condensation water formed after condensation and frosting.
In the north, it is not advisable to get the diversion pipe outside, which is not advisable, because the north winter outdoor is lower than zero degree is normal, the diversion pipe will inevitably freeze, the pipe freeze can not guide the flow.
3. The total heat exchanger has the function of regulating indoor air humidity.
We take the hot summer humidity in southern China as an example: high outdoor temperature, high humidity (38 degree, relative humidity 90%), low indoor temperature, high humidity (using air conditioning, 26 degrees, relative humidity 90%).
Can we reduce indoor air humidity through the fresh air system?
Sensible heat exchangers must not be able to, because aluminum as an exchange medium is not permeable and can not exchange humidity.
So can the whole heat exchanger be able to do it?
Knowledge point 1: the humidity we usually say is relative humidity. In the case of the same relative humidity, the content of water in the air with high temperature is greater than that of the low temperature air.
Knowledge point 2: water in the air is transmitted through pressure. The pressure is large and the pressure is small.
If there are 3 drops of water in the outdoor air of 38 degrees outside, and 2 drops of water in the indoor air of 26 degrees in the room, then when the two strands of air meet in the full heat exchange core, the water molecules, which have more pressure, will transmit the water molecules to the indoor exhaust side, thus the water molecules in the new air entering the room are less and the humidity is reduced.

What is the difference between an intelligent polishing machine and a traditional polishing machine?
The traditional polishing machine usually needs to make a polishing workshop separately, because the polishing is the grinding of the rough surface of the metal surface. According to the requirements of the smooth surface of the workpiece, the polishing wheel with different hardness is replaced, and coarse grinding, medium grinding and fine grinding are carried out. The end of the desired purpose.

Our newly developed automatic polishing machine and grinding machine are more durable, more efficient and convenient, and can only be achieved by combining robots and manipulators.
Human production.

Looking at the above comparison, are you still polishing by hand? A good polishing machine is equal to a few polisher. We are still polishing the headache customers. Please pick up the phone.
The difference between numerical control lathes and ordinary lathes
Numerical control lathe refers to the use of numerical control program to control the purpose of the machine tool, so that the operation of batch automatic processing. Today, the standard lathes have better adaptability compared with ordinary machine tools. They can be processed on some parts with smaller volume and more complex structure. High precision, in production has better efficiency, can be realized in the same walking bed for many process processing, in addition to low labor intensity, high degree of automation advantages.
2-TCKZ-20N-400-400
Ordinary horizontal lathes are often used in turning the inside and outside turning surface of the product and the processing of thread. Usually, the tools are used to drill holes and expand holes. It is a kind of lathe used at home at present, which accounts for 65% of all the total.
The difference between the ordinary lathe and the numerical control lathes
1, the common lathe used the thread of the trapezoidal thread to process the thread while machining the thread. At the same time, the lathe used the light rod to process the cutting, while the CNC lathe used the ball screw to process the thread when the thread was processed.
2, numerical control lathe and ordinary lathe tool holder position is different, the position of the heart bed is basically on the left of the operator, and the position of the ordinary lathe is usually on the right of the operator, for the different position of the good or bad, as long as more convenient operator to operate it.
3. Two rails are also different in the guide way. The guide rail of the ordinary lathe is rigid rail, while the core bed has a line rail besides hard rail.
4, the handle of the ordinary lathe is equipped with more, large, medium and small trailer handle, and these are not in the heart bed, not only so also there is no small trailer, the reduction of these accessories, shorten the operation process, let the workers in the operation more convenient.
5, in the equipment of the motor, the two kinds of lathes also have a big difference, the spindle motor of the ordinary lathe can be used by ordinary motor, but if it is a heart bed, it usually uses a variable frequency motor.
6, the heart bed can achieve a larger scope of automation, in the spindle, feed, cooling pump control, the use of traditional lathes are manual control, the heart bed can be fully automated, of course, can be operated manually.
7, in addition, ordinary lathe has no digital control operation, but the center bed has.
Advantages of numerical control lathes
The heart bed has a better processing precision. It can get better product quality at the time of processing. It can carry on the movement of multiple coordinates. For some parts with more complex shapes, it can also be well processed. If it is the time to change the parts needed to be processed, only the numerical control program can be changed. And no other operation steps are needed, so that the production preparation time can be saved to a large extent. In terms of productivity, the bed is very high, which is more than six times higher than that of ordinary machine tools.
CNC lathes do not have too many steps in the operation, so the quality of the operators is not particularly high, but the requirements of maintenance are higher, so we need to hire professional equipment maintenance personnel, if they do not understand, they can not be at random.
Precautions for the use of tractors
(1) the throttle should not be placed at the maximum position at startup. When the engine is started, the throttle should not be placed in the maximum position, otherwise the engine can reach a high rotational speed and discharge a large number of black smoke at the same time, which will aggravate the wear of the parts and shorten the service life of the machine. When starting, the throttle should be placed in the middle oil gate position.
(2) the cause of engine reversal at startup. When starting, if the engine comes out of air filter smoke and muffler intake, this means that the engine is reversed. Most of the engine reversal is due to the excessive oil advance angle. Oil has been supplied before the piston has reached the level of fuel supply. When the fuel is deflagrated ahead of time, the piston is pushed back and the crankshaft is reversed; in addition, when the engine is started, the rolling time is too long and is not started, the fuel accumulates too much, and it can easily cause the reversal, or when the flywheel is rocking, the pressure relief handle is moved to the “running” position and satisfies the mixture when the piston does not reach the stop point. Combustion conditions, the mixture of deflagration after the piston back, resulting in reversal. When the engine reverses, the order of the intake and exhaust stroke is reversed, and the oil of the oil tray in the air filter is often flushed out, the engine sound is abnormal, and the parts are very easily worn. Once the reversal occurs, shut down the accelerator immediately and stop the fire.
(3) in winter, after the tractor stops, the cooling water can not be released immediately. The normal working temperature of the engine is 75~95 degrees, while the external temperature is very low in winter. After the tractor stops, if the cooling water is released immediately, because the surface of the metal parts is cooled and contracted suddenly (the metal temperature in the machine parts is still high, it seldom contracts), it is easy to make the body and cylinder head produce deformation and crack. Therefore, in winter, the cooling water must be released when the water temperature drops to 40~50 degrees after the engine is extinguished.
(4) no cold water can be added to the engine when the engine is overheated. When the engine needs to add water due to the lack of water in its work, it should not immediately add cold water. Otherwise, the body and cylinder head will crack due to the sudden shrinkage of local temperature and shrinkage of metal. When adding water to work, the engine should be operated at a low speed for 10~15 min, and when the water temperature is lowered, the cooling water will be slowly added to the engine.
(5) no long-term overload operation. Some drivers, because of the lack of common sense of agricultural machinery, want to earn more money and increase their loading at random when they are engaged in transportation operations. Due to overloading operation, the fuel supply is increased, the rotational speed is reduced, and the fuel combustion is bad. This will not only increase the wear of parts, but also reduce the service life of locomotives. So, do not overload the locomotive.
