Abstract

An energy-saving electrically driven hydraulic water pump composed of hydraulic apparatus has a supporting frame of three columns and a hydraulic cylinder over the supporting frame for driving the pumping cylinder under it. When the small piston in the hydraulic cylinder moves upward, the water inlet valve is opened and the water outlet valve is closed. When it moves downward,the water inlet valve is closed and the water outlet valve is opened. Thus a water pumping procedure is completed. Its advantages are saving energy, low cost high efficiency.

Description

Energy saving electric hydraulic water pump

The present invention relates to a kind of suction engine of forming by hydraulic pressure installation.

In the present prior art: suction engine all is to draw water with blade type or wind wheel type, and hydraulic water pump is not used more widely in actual product as yet.

Purpose of the present invention provides a kind of energy-efficient suction engine.

The present invention utilizes three cylinders as support, and the top has an oil hydraulic cylinder that makes pressure back and forth to inhale one as power one to push the limit pumping tank.Driving the pumping tank big piston when the little plug cock in the oil hydraulic cylinder moves upward moves upward, at this moment, inlet valve is opened, outlet valve is closed, and drives the pumping tank piston and move downward when the little plug cock in the oil hydraulic cylinder moves downward, and this moment, inlet valve was closed, outlet valve is opened, thereby finish a pump process, reciprocal like this, just can constantly draw water.

Because this suction engine has adopted hydraulic pressure installation, promptly saves a large amount of energy, improves the suction journey (more than 100 meters) of suction engine again greatly, lift (more than 100 meters) also can be reducingd the construction costs significantly, and is easy to maintenance, long service life, incomparable with existing suction engine.

The drawing explanation please be seen " specification " accompanying drawing

The present invention is further detailed explanation with embodiment in conjunction with the accompanying drawings: the described hydraulic waterpump belt pulley 1 of accompanying drawing drives the blade oiling, pressure gauge 2, relief valve 3, solenoid valve 4, the reciprocal oil supplying device oftransport pipe 5 common compositions exchange oiling up and down in oil cylinder 7.In thesmall piston 10 upper part small oil tanks, piston area and has double-deck oil sealing more greatly.Big piston 12 is connected withsmall piston 10, andpumping tank 13 inferior horn both sides have inlet valve 14 andoutlet valve 15 respectively, and pumping tank first half inwall has double-deck water seal.This unit efficiency height, simple in structure, be convenient to large-scale popularization and use.

Claims (1)

1. Energy saving electric hydraulic water pump is to utilize three cylinders as support, and the top has one to make the oil hydraulic cylinder of pressure push the limit pumping tank as a suction one back and forth.Driving the big piston that draws water when the little plug cock in the oil hydraulic cylinder moves upward moves upward, at this moment, inlet valve is opened, outlet valve is closed, and drives the pumping tank piston and move downward when the little plug cock in the oil hydraulic cylinder moves downward, and this moment, inlet valve was closed, outlet valve is opened, thereby finish a pump process, reciprocal like this, just can constantly draw water.It is characterized in that: draw water with hydraulic pressure installation.
