This standard specifies the type, category, grade, model, size and parameters of the inner and outer rotors of JZS series powder metallurgy oil pumps. This standard applies to powder metallurgy rotors of oil pumps for internal combustion engines below 196kW: the oil pump speed is 1000~4000r/min, and the flow range is 0.5~157L/min. Medium-pressure rotor pump powder metallurgy rotors and rotors made of other materials used in hydraulic systems can also refer to this standard.
