introduction： （1）Have the right viscosity To ensure good lubrication and sealing of compressed gas，Lubricating oil must have a certain viscosity，And the viscosity of the compressor will increase under high pressure。Such as：1MpaThe viscosity is20mm2/sOil in10MpaWill increase to40mm2/s，Excessive viscosity，Not only waste power，And the surface oil film recovery speed is slow，Increase wear，Also easy to cause sludge and carbon deposits，Low viscosity，Easy to make the cylinder piston between the formation of reliable oil film，Cause air leakage，So choose to consider the exhaust pressure，Final pressure temperature compressor series and other factors。
