This standard specifies the terms and definitions, models, basic parameters, requirements, test methods, inspection rules, marking, packaging and storage of general oil-injected screw air compressors (hereinafter referred to as "screw air compressors"). This standard is applicable to general fixed and modified moving screw air compressors with driver power of 2.2 kW~630 kW and rated exhaust pressures of 0.3 MPa (0.5 MPa), 0.7 MPa (0.8 MPa), 1.0 MPa and 1.25 MPa. machine. Other screw air compressors with a rated exhaust pressure not greater than 1.6 MPa can also refer to this standard. This standard does not apply to general variable frequency oil injection screw air compressors.
