This standard JB/T 53148-1999 specifies the product quality grading for non-lubricated reciprocating piston high-pressure oxygen compressors, applicable to those with suction pressure 0.002~0.020 MPa, discharge pressure 16.2 MPa, and volume flow up to 300 m3/h. Products are classified into three grades: qualified, first-class, and superior. Key assessment indicators include volume flow, annual average availability, specific energy, noise sound power level, vibration severity, and oil residue on oil-free parts. Test methods reference relevant national standards, and sampling requires item-by-item evaluation with the lowest indicator determining the final grade.
