Influencing factors of screw air compressor displacement

What are the factors affecting the displacement of screw air compressor？

1. Leakage. The internal structure of the screw air compressor is not in contact with each other during operation, and it is not very tight, so there will be gas leakage. When gas leaks, the exhaust volume at this time will be reduced. Usually, in order to avoid this situation during design, there is a special meshing gear to avoid air leakage, but when the gear is damaged, gas leakage will still occur, thus affecting the exhaust volume.

2. Inhalation condition. The screw air compressor is a volumetric air compressor. When this type of air compressor is running, the temperature of the gas will rise, or when the air pipe for transporting the gas is blocked, the density of the gas in the air compressor will increase. Reduced, so the exhaust volume at this time will also be reduced.

3. Cooling condition. During the operation of the screw air compressor, the mutual friction of the internal components will cause the temperature of the machine itself to rise. It will also expand when heated, the density will decrease, and the exhaust volume will also decrease accordingly. If there is a good cooling system at this time, this situation can be avoided.

4. Speed. When the rotation speed of the screw air compressor increases, the displacement of the air compressor will also increase at this time, and vice versa, it will decrease. Therefore, increasing the rotation speed of the air compressor is also a means to increase the displacement, but the Factors of speed include voltage and so on.

The scheduling situation of the screw air compressor is the performance of a machine, so if we encounter the situation of reduced displacement during work, we can start from these points to solve the problem.
