The piston machine is directional and must be installed with a phase sequence protector. In case the circuit phase sequence changes, it will protect it and not work. The spiral type is good, it has no direction, the wiring direction is not specified, and the work is stable.

The spiral type is good, it has no direction, the wiring direction is not specified, and the work is stable. Screw type air compressor is widely used in industrial production, in its control using loading-unloading valve to control the air supply of air compressor.
Due to the working cycle of the gas equipment or the difference of the production process, the gas consumption fluctuates, which sometimes causes the air compressor to load and unload frequently. The piston machine is a reciprocating intermittent air supply, with large airflow pulsation during operation, low degree of automation of the piston air compressor, and basically no automatic control system. The adjustment of the output pressure is realized by the control of the loading and unloading valve and the regulating valve. The speed is slow, the fluctuation is large, the accuracy is low, and the output pressure is unstable.
Compared with the screw air compressor, the efficiency of the piston air compressor is low, especially the long-term continuous operation, and its economy is worse. Since many of the compression chambers formed by the piston air compressor are wearing parts, the wear and damage of these wearing parts will cause greater leakage during gas compression, resulting in a decrease in compressor efficiency.
Screw air compressor failure is very few, as long as the regular maintenance of oil and gas separator, air and oil filter, etc., can ensure its normal operation. The maintenance outside the maintenance of the 2 10m3 screw air comperssor used is the blockage of the sewage pipe and the failure of the control panel. For 2 years, the main engine system has been running normally.
