Information

The screw air compressor adopts a pre-packaged screw air compressor with only a single power connection and compressed air connection, and a built-in cooling system, which greatly simplifies the installation work. So what are the factors that affect its actual displacement? Let’s take a look at it with the editor of Variable Speed ​​electric driven screw air compressor SPM35Y!
1. Equipment speed
The displacement of the screw air compressor is directly proportional to the speed, and the speed tends to change with the voltage and frequency of the power grid. When the voltage decreases or the frequency decreases, the speed will drop, reducing its exhaust.
2. Inhalation
It is a positive displacement compressor, with the same suction volume. 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 reduce the screw air compressor displacement accordingly.
3. Gas leakage
There is no contact between the rotors and between the rotor and the housing during operation, and there is a certain gap, so gas leakage will occur. When the pressure increased gas leaks through the gap to the suction pipe and the sucking groove, the exhaust volume will be reduced. In order to reduce the amount of leakage, sealing teeth are made on the tooth top of the driven rotor, sealing grooves are opened on the tooth root of the driving rotor, and ring-shaped or strip-shaped sealing teeth are also machined on the end surface. If these sealing lines are worn out, the leakage will increase, so these factors should be taken into consideration during normal maintenance.
The above is the editor of Variable Speed ​​electric driven screw air compressor SPM35Y: You can learn more about the factors that affect the actual displacement of screw air compressors.
