Description
Technical field
The present invention relates to a kind of high pressure two-chambers to be mostly used water delivery mechanism, belongs to civilian water delivery machinery field.
Background technology
The Northwest in China, since rainfall is few, geographical environment arid, most parts of the north all suffer from dampening money
The sternness of source scarcity is lived bad border, is all lived using well and agricultural irrigation in the most of areas in the north, however in recent years by
So that water resource utility model is serious in the felling of forest and the destruction of Ecological environment, initial detention reduced capability, the depth of well is not
Disconnected increase extracts domestic water to residents and brings great difficulty, secondly in the southern area in China, due to precipitation
Greatly, lake is numerous, so can be more than often that warning line even breaches a dyke there is a situation where water level when rainy season set, to the urgent people that speedily carries out rescue work
Member brings prodigious difficulty.
Present existing water pump mechanism is revolved by impeller high speed come work using centrifugal principle and atmospheric pressure difference
Turn, drives liquid to rotate together, under the influence of centrifugal force, fly away from impeller and project outward.After liquid discharge, at blade center
Vacuum low-pressure area is formed, the liquid in liquid pool flows under the action of the atmospheric pressure of pond face, and through suction line in pump, and water pump is all
It is that an external water pipe draws water to realize, the working efficiency for so allowing for water pump is greatly reduced, and well depth is continuous
Increase, this makes original old-fashioned water pump be no longer able to meet the requirement of working environment, moreover existing water pump can not go deep into
To underwater operation, work can only be maintained by way of externally fed on the ground, therefore a kind of high pressure two-chamber is mostly used water conveying machine
The invention of structure just seems extremely urgent.
Invention content
To overcome the shortcomings of that pump head is small in the prior art, efficiency is low and cannot be deep into underwater operation, the present invention carries
It is mostly used water delivery mechanism for a kind of high pressure two-chamber different from raw water pump technical principle, the water delivery mechanism lift bigger is more efficient,
It can work under complex environment.

It is connected through a screw thread between the gear frame, ball head universal, piston rod.
In the hollow tube, hollow tube is fixed on babinet by lid sealing of restricting for the electric wire setting that the motor is connect with power supply
On, hollow tube can be the plastic type pipe of softness, be used for waterproof.
It is provided with handle on the babinet.
I, the check valve allows water to flow into water chamber from intake antrum, and II, check valve allows water to be flowed to out of water chamber
Outside babinet, III, check valve allows water from babinet in inflow intake antrum.
The present invention the course of work be：
After electric motor starting, transmission shaft I is driven to rotate by flange-face coupling, the rotary motion of transmission shaft I and transmission shaft II makes biography
Two expenditure framves of moving frame are swung up and down within the scope of certain space（Therefore gear frame and piston rod are connected with ball head universal
It connects）, the expenditure frame of the gear frame swung up and down can be pumped by piston rod band piston；When in intake antrum
When piston upwards（The piston in water chamber is moving downward simultaneously）, intracavitary and outside form pressure difference, to external
Water pass through in the water inlet inspiration intake antrum equipped with check valve III（The water in water chamber passes through going out equipped with check valve II simultaneously
The mouth of a river is forced out）, when piston moves downward in intake antrum（The piston in water chamber is moving upwards simultaneously）, intake antrum
Water be pressed by the water transport channel equipped with check valve I（Sucking）It, and so on can be external by water outlet in water chamber
Water pipe it is lasting deliver water to ground.
The invention has the advantages that being：
（1）Water delivery work can be completed in complex environment and deep-well, it is of low cost, it is suitable for home use；
（2）High pressure two-chamber water delivery device has used the principle of reciprocating motion of the pistons formation pressure difference, securely and reliably, simple in structure, real
It is good with property；
（3）Lift is big, efficient, saves working time.
Apparatus of the present invention realize that the piston of two chambers makees reciprocal up and down motion, to realize water suction and pressure water, while coordinating list
It is realized to valve control controlling flow direction in varying environment（Such as deep-well, shoal, reservoir）Lower high-pressure water delivery work, meets real life
The needs of production.
