The mouth of pipe of the water inlet pipe other end is fixed on the bottom surface dividing plate beside the periphery of the corresponding piston cylinder of outside drive shaft；It is described enter
Water pipe is provided with side apopore in the periphery of the corresponding piston cylinder of main drive shaft, the water yield of the side apopore be less than into
The mouth of pipe water yield of the water pipe other end.
It is to the further improvement that the present invention is done：The quantity of the water inlet pipe is 3.The quantity of the drive shaft is 3
Individual, main drive shaft is located at centre, and both sides are respectively outside drive shaft and inner side drive shaft, ellipse provided with 3 in each drive shaft
Boss wheel, is provided with 9 piston cylinders corresponding with elliptic cam, between main drive shaft and outside drive shaft in each interior of drawing water
And by gear drive between main drive shaft and inner side drive shaft, main drive shaft is connected by main drive shaft gear and final drive shaft
Connect reductor and motor.The piston rod end is provided with the termination bearing that can be contacted with elliptic cam.
It is using the beneficial effect produced by above-mentioned technical proposal：The mouth of pipe of water inlet pipe one end of the present invention is fixed on into water
Lower cartridge inwall, the mouth of pipe of the water inlet pipe other end is fixed on and entered the distant piston cylinder periphery of water mantle, can be to piston
The inflow of cylinder is adjusted, and makes into water equilibrium assignment, makes each piston cylinder can normal pumping, it is ensured that pump housing normal work,
Extend the service life of piston pump.
