In general, the volumetricefficiency of pump power higher than the pump.
总的来说，容积泵的效率高于动力式泵。

Pump valve spring fracture is another common typical fault of emulsion pump with high pressure and large discharge which reduces the volumetricefficiency of emulsion pump greatly.
泵阀弹簧断裂是高压大流量乳化液泵的另一种常见典型故障，极大地影响了乳化液泵的容积效率。

Using the meshing principle, we raise computer-simulated generation method and compare volumetricefficiency with other kind of claw type dry vacuum pump.
