What is the structure of the check valve of the screw air compressor?
Screw air compressor check valve has two kinds: one is to open pressure, one is no need to open the pressureIn the screw compressor, there are generally several places with check valve: intake valve, main engine exhaust, oil return check valve, minimum pressure valve.The check valve is a one-way flow principle
Work process: air pre filter, and then through the air filter and the air inlet controller into the mixing chamber and the compression screw lubricating oil, continuous linear by asymmetric rotor two, compression. The compressed oil and gas mixture enters the tank and the separation system for three levels of separation (centrifugal, self weight, and fine separation). The separated compressed air is discharged after the cooler is cooled, and a reliable pressure switch system controls the exhaust pressure. When the machine is running, the screw compressor run oil system by pressure difference automatic circulation, without pump. When starting, the minimum pressure valve is closed to ensure the minimum pressure required for the lubrication oil circulation. In addition to lubrication, the oil also acts as sealing, cooling and reducing noise. High efficiency oil and gas separator and high efficiency cooler ensure high quality compressed air.
