Therefore, the full use of advantages of tidal level of the Yangtze River so as to lower the delivery lift and increase the pumping capacity and save energy consumption and raise operation reliability, are implemented.
Screw pump drived by submersible motor is rodless oil pumping which can achieve high delivery lift and low delivery capacity. It can attain the purpose of low cost and high efficiency.
In the research of the influences of geometrical parameters of centrifugal pump on the delivery lift, particular attention should be paid on the research of synthetic influence.
High delivery lift and high backpressure required in fuel throttle valve test were obtained through higher rotation speed of the main pump.
