An important role is to lubricate the cylinder, to cool the cylinder. And form a space oil supply circulation system, before starting, first start the oil pump control system, oil pump control system after starting to ensure good lubrication of air compressor lubrication parts, at the same time, the oil pump control system can adjust the internal oil pressure and oil temperature through the built-in temperature control valve, to meet the needs of the system. Air circulation system: When the compressor is working, the air is inhaled through the self-cleaning air filter, and the filter is automatically cleaned by PLC. The air enters the first-stage compression after automatic adjustment by the inlet guide vane. The temperature of the gas after the first-stage compression is higher, and then enters the intercooler for cooling (water in the pipe, gas out of the pipe, etc. Knowing the water flow in the device for 110 m/h) after entering the secondary compression system, in order to avoid the system gas into the compression chamber (avoid starting) under pressure in the compressor exhaust pipe installation there is a suspension of the check valve, compressor exhaust gas pushed open the check valve into the exhaust muffler, and then enter the primary cooler, cooler after secondary, again into the exhaust pipe main.
