Abstract
The results of simulation of the pressure at the outlet of the pump and the coefficient of cells filling are given depending on the number of rotor vanes, the structural dimensions of the pump and eccentricity. Experimental investigations were carried out to determine the volumetric efficiency (or filling factor) and a comparison is made by the specific filling factor per unit of power of the pump drive. The power consumption per unit of volumetric efficiency of cells with air for rotary vane pump with rotating stator is 30% lower than for a fixed stator pump. A pump with a rotating stator, for identical structural and kinematic parameters with rotary pump with a fixed stator, at a productivity of 60 m3/h and a vacuum of 50 kPa consumes 1250 watts less power.
