No pressure in the cylinder before the air compressor of air separation unit starts

From the starting characteristics of the motor driving the air compressor, it can be seen that the current of the motor starting is several times larger than that of normal operation. The strong starting current has a great influence on the motor itself, transformer and transmission line. In order to reduce the starting time and starting current, no-load is a more effective measure. Based on this requirement of motor starting, before starting the air compressor, the pressure of all levels of pressure gauges should be checked. If there is air, the air should be released.
