Reciprocating pumps convert rotary motion to linear motion. Pumpspeed in RPM determines the pumps output volume for any given combination of cylinder bore and piston stroke.
循环泵将曲轴旋转运动转化为柱塞的直线运动。泵速转每分钟决定了任何气缸和活塞组合的排泵量。

As there were leak on contact place between shaft and rotor body in built up hollow rotor, dropping discharg gas speed of pump and efficiency applied of oil sealed sliding vane rotary vacuum pump.
The input electric current, voltage, rotaryspeed, output flux and output pressure of the pump were tested. The regression relation of these parameters was deduced.
