Answer: The oil injected into the oil-injected screw air compressor is mainly used to remove the heat generated by the air during the compression process. The amount of oil injection directly affects the performance of the compressor. When the amount of oil injection is insufficient, the exhaust temperature at the air compressor outlet rises, and the air compressor bearings will also vibrate; when the amount of oil injection is large, too much oil will accelerate the formation of carbon deposits in the air compressor; The control of the oil injection amount depends on the oil supply valve on the lubricating oil line, and the opening of the oil supply valve is generally 90%.
