First of all, we must know that the main factors affecting the air compressor displacement are as follows:

1. Leakage: There is no contact between the rotor and the rotor of the air compressor and between the rotor and the housing during operation. There will be a certain gap, so gas leakage will occur.
2. Rotation speed: The exhaust volume of the air compressor is directly proportional to the speed. The speed often changes with the voltage and frequency of the grid.
3. Inhalation state: the general volumetric air compressor, the inhalation volume remains unchanged. When the suction temperature rises or the suction pressure decreases due to the excessive resistance of the suction pipe, the density of the gas decreases, which will correspondingly reduce the quality of the gas exhaust.
4. Cooling effect: The temperature of the gas will rise during the compression process, and the temperature of the air compressor rotor and casing will also rise accordingly. Therefore, during the suction process, the gas will be heated and expanded by the rotor and casing, so the corresponding The ground will reduce the amount of inhalation.
If you want to increase the displacement of an air compressor, that is, increase the output coefficient, you can usually use the following methods:

① If necessary, clean the cylinder and other parts.
② Correctly choose the size of the clearance volume;
③ Adopt advanced cooling system;
④ Maintain the tightness of the piston ring;
⑤ Reduce the resistance during gas inhalation;
⑥ Maintain the tightness of the valve and stuffing box;
⑦ Maintain the sensitivity of the suction valve and exhaust valve;
⑧ Dryer and colder gas should be inhaled;
⑨ Properly increase the speed of the compressor;
⑩ Maintain the tightness of the output pipeline, gas valve, gas storage tank and cooler.
