Beschreibung
Zusammenfassung:	The utility model provides a rotor structure of positive -displacement pump, including integrative rotor main part and the coupling seat that takes shape, the rotor main part has an at least blade, the coupling seat by at least one connect rib group solid in the central authorities of rotor main part, just the coupling seat has a coupling hole and at least one locates axle key on the coupling hole. Consequently, provide this rotor and have lighter quality, can provide the pump and possess lower inertia in the operation process, and can reduce the energy that the rotation consumed for mutually unidimensional pump has higher compression and when carries the volume, and the improvement coordinates pivoted accessories life with it.
