Operation principle：
In the closed pump housing when direct current generator driving rotor rotation, it is formed by between adjacent two scraping blade on the pump housing and rotor
The variation of swept volume forms pressure difference to convey liquid.Rotor has several radial slots, installs scraping blade in radial slot, scraping blade can
With free to slide in slot, rotor seal is mounted in the pump housing, and when rotor is driven to rotate, scraping blade is pressed on by centrifugal force
On the inner wall of the pump housing.The half-turn before rotor rotates, the space that adjacent two scraping blade is surrounded gradually increase, and form parital vacuum and inhale
Enter liquid；Then half-turn, this space are gradually reduced, and liquid are squeezed, by feeding liquid under pressure to discharge pipe.
Return valve is equipped between oil inlet pipe and drain line, return valve oil discharge outlet moment during fuel-displaced closes,
Return valve is opened when fluid pressure increases suddenly, and liquid can be recycled in pump body, and buffering is due to instantaneous increased
Pressure slows down transient liquid and stops the vibration generating, plays a protective role to pump and motor.
