This kind of pump can effectively solve the problem of low cubage efficiency, high degradation of viscosity of tri-material compound system, short service life for .

Based on such working principles as eccentric screw pumps, frictional velocity and cubage efficiency, wears on rotor and stator surfaces are accordingly demonstrated using Matlab TM.

Influence of stator rubber plumping of screw pumps on volume efficiency and countermeasures;

The calculation of the volume efficiency of rod pumps includes the calculation of four parameters, i.

This paper deals with simulating study on the volume efficiency of mine emulsion pump.

New formulas for volumetric efficiency are created by optimization of the classical formulars,Multiple non-linear mathematical method is taken use of to get fitted coefficient.

Volumetric efficiency is critical to the overall performance of hydrostatic transmission and it has a bad influence on popular application of hydrostatic transmission in high-speed military vehicles.

1 ms, but its volumetric efficiency decreases obviously with an increase in pressure at speed less than 1 000 r/m in.
