Analysis and Research on New Type of Double-acting Contactless Sliding-vane Pump

A new type of Double-acting Contactless Sliding-vane Pump was put forward to the defect analyzed on Sliding-vane,which uses roller to control the locus of sliding vane to insure the minute gap between the stator and sliding vane.Basicing on the comparison,we can find the new type of Slidingvane Pump has comparison performances,such as unique structure,good stress on sliding vane and steady flux.
