          Non-lubricated air compressor piston
          Date:2012-04-26 16:17:23
          No oil lubricated air compressor cylinder piston rings and packing device packing PTFE filled with self-lubricating properties are used as a sealing element. Thus, the cylinder and the packing device is not required to inject lubricating oil through the compressed gas, under normal circumstances substantially pure excluding oil, screw compressor without increasing the oil cleaning device. The shortcomings of the aircraft is too large for the motor power, the exhaust pressure is not stable enough, the exhaust temperature is high, the noise is too large, the maintenance workload, high maintenance costs.
