What should I do if the temperature of the screw air compressor is too high?

1. For the placement requirements of the screw air compressor, choose a suitable center, which should be wide and well ventilated, so that the hot air distributed by the air compressor can be dispersed in time.

2. Check whether the operating oil circuit of the screw air compressor is correctly configured.

3. Regularly check the inside of the air compressor: whether the internal parts such as radiator and oil filter are damaged or defective, and whether the oil meets the standard

How to deal with the high exhaust temperature of the screw air compressor? Nowadays, the summer vacation is coming, and the temperature is getting higher and higher. Many customers report that the exhaust temperature of the screw air compressor is too high, and some of them are even empty If the temperature of the press is too high, it will alarm and stop. What should I do? What causes it?

1. The operating environment of the screw air compressor: the space is closed and not ventilated, and the hot air emitted by the air compressor cannot be removed in time, resulting in the continuous high temperature of the operating environment of the air compressor.

2. The radiator is blocked and cannot dissipate better heat.

3. Insufficient cooling oil.

4. The engine oil is of low quality and cannot meet the requirements of machine operation.

5. The filter element of the oil and gas separator is too dirty, forming too much resistance and affecting the circulation of the cooling system.

6. Whether the oil circuit of the screw air compressor is operating correctly.

At present, with the progress of society, many customers will be deceived by sweet words when purchasing screw air compressor lubricating oil, resulting in poor quality of the lubricating oil purchased. To prevent this situation, it is necessary to control the basic knowledge of smooth oil. The common knowledge of lubricating oil for lower screw air compressor is introduced below.
1. Smoothing performance: The smoothing performance of oil is related to the viscosity of the oil. Generally speaking, there is no decrease in viscosity, which means that the smooth performance is deteriorated. After the smoothing performance is reduced, the adhesion and tackiness are correspondingly deteriorated, and the strong oil film cannot be formed, and the smoothing effect cannot be exerted.
2. Moisture: Put the screw air compressor oil into the test tube and check the transparency. If it is not clear and transparent, but turbid, it can distinguish the water contained in the oil. There are two kinds of whether it contains water, and there are two reliable methods.
3. Viscosity: Check that the oil that meets the quality specifications is put into the test tube, sealed with cork and wax, not filled, leaving a space of about 5 mm.
4. Impurities: Put the oil into the test tube and observe the suspended granular impurities. The above is the basic knowledge of the lubricating oil of the screw air compressor and the method of judging the quality of the oil. But if the fan of the variable frequency screw air compressor can also use the variable frequency system, then the noise generated by the variable frequency screw air compressor can be reduced more significantly.

Air compressor maintenance: The air compressor displacement is too low; the cause of this problem may be: lack of horsepower of the diesel engine or electric motor; damage to the valve spring; air leakage of the cooler or vent pipe, etc. The main solutions are Adjust the working horsepower of the diesel and electric motors, replace with new springs; tighten the loose connecting rod screws to avoid air leakage. The cooling efficiency of the cooler is low; the cause of this problem may be: too much dirt on the cooler has accumulated, which affects the heat transfer effect; the main solution is to check and clean the dirt on the cooler in time to improve the cooling efficiency. The structure of the air compressor is very complicated, and there are many parts and components that are touched. Any small part including a small screw may cause problems with the air compressor. There are many reasons for the problems in the outside world. In the maintenance of the air compressor Among them, if non-professional maintenance personnel and testing equipment, it is difficult to accurately find and deal with the faults, air compressor maintenance requires professionals, professional tools and technical talents to really find and remove the faults.

Why the compressor needs to be shut down in an emergency? It is inevitable that the compressor will have such problems in the process of use. Although it is a small problem, it can't make the compressor work normally. This makes people very angry. We often neglect this kind of problem. Small problem, when the exhaust temperature exceeds 100 degrees Celsius or the load of the motor, the motor will start the maintenance and installation, the over-current maintenance and installation will automatically cut off the power, and the control panel will display an overload alarm. At this time, we must stop processing immediately. If the compressor is not handled properly, the motor of the compressor will be burnt. Therefore, the motor should be stopped immediately while the discharge valve is opened and the intake valve is closed to prevent the coolant from continuing to spray out of the compressor. As long as the unit is in abnormal conditions during operation, In order to stop an emergency stop, the variable frequency screw air compressor has an exponentially higher air pressure stability than a power frequency driven air compressor. 3. The AC power supply of the variable frequency screw air compressor has better voltage compliance. The inverter of the variable frequency screw air compressor can adopt over-modulation technology, so that the AC power supply voltage can still output enough torque to drive the variable frequency screw under low conditions. The motor of the air compressor stops working. And if the current and voltage are slightly higher, the output voltage will not be too high. 4. The noise of the frequency conversion screw air compressor is low. Most of the frequency conversion system of the frequency conversion screw air compressor stops working at lower than the rated speed, so the noise generated by its main machine is very small. It is precisely because it stops working at lower than the rated speed, so it also extends the service life of the frequency conversion screw air compressor.

Excessive noise during work; there may be two reasons for this problem, one is the bearing damage at the intake or exhaust end; the other is the bearing damage of the motor. To completely deal with the problem of excessive noise, it is necessary to replace the corresponding bearing To deal with. The temperature of the compressor is too high; the reason for this problem is not only the lack of oil in the compressor, but also the corresponding partial obstruction, which mainly includes: the oil filter is blocked; the surface of the oil cooler is blocked. Infarction; the filter element of the oil and gas separator is blocked or the resistance is too large. When the temperature caused by lack of oil is too high, it can be treated with proper refueling; and when the temperature caused by the corresponding local infarction is too high, it needs to be removed to stop cleaning, and it can be changed if necessary.
