Description
Technical field
The present invention relates to a kind of water pump, particularly a kind of Centrifugal water pump with self-absorption function.
Background technique
The present patent application people discloses " double-vane mixing self-sucking pump " CN1165919A before this, this pump is made up of the pump housing, impeller and pump shaft, cooperate motor to implement, impeller cavity is made up of a self-priming impeller cavity and a centrifugal impeller chamber in the pump housing, and separate by two-way blind flange, divide in the chamber to be equipped with self-priming impeller and centrifugal impeller, self-priming impeller and centrifugal impeller are contained on the same pump shaft, and intake pipe communicates with the centrifugal impeller chamber; The pump housing is provided with the extrusion cavity and communicates with outlet pipe, and the suction journey and the lift of this pump are limited, still are further improved.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, and provide a kind of high-efficiency energy-saving multi-use water pump, have self-priming pump and centrifugal pump dual functions, under the constant situation of power, the existing relatively pump of technical performances such as its lift, pump efficiency, flow all improves a lot, and consume energy low, volume is little.
For achieving the above object, the invention provides following technological scheme:
The invention provides a kind of high-efficiency energy-saving multi-use water pump, form by the pump housing, impeller and pump shaft, impeller cavity is made up of self-priming impeller cavity and centrifugal impeller chamber in the pump housing, divides in the chamber to be equipped with self-priming impeller and the centrifugal impeller that is contained on the same pump shaft, and intake pipe communicates with the centrifugal impeller chamber; The extrusion cavity of the pump housing communicates with outlet pipe; It is characterized in that: the bottom of described intake pipe is built-in with liquid jetting device, liquid jetting device is by jet mouth, jet cavity and increase and inhale pressure supply water pipe and forms, and jet mouth chamber is young greatly, and its outlet and jet cavity are on same axis, increase suction pressure supply water pipe one end and communicate with the jet mouth, the other end extrudes cavity with the pump housing and communicates.
Be provided with a water inlet and an osculum in the above-mentioned self-priming impeller cavity, have on the runner between two holes and extrude the aperture that cavity communicates, the water inlet communicates with the centrifugal impeller chamber, osculum with extrude cavity and communicate.
Above-mentioned aperture is arranged on and is provided with one between two holes and is higher than on the cut water of runner.
Be provided with filter screen in the above-mentioned extrusion cavity.
Above-mentioned centrifugal impeller chamber more than two is coaxial stack.
The spool of above-mentioned check valve is a round platform, the one side be extended with axis, the boss of another side is provided with a pad, its valve body in a tubular form, the both sides of tube wall have osculum.
The spool of above-mentioned check valve is a bulb.
Above-mentioned self-priming impeller is single face umbrella tingia wheel or two-sided umbrella tooth self-priming impeller.
Above-mentioned centrifugal impeller is closed centrifugal impeller or open type centrifugal impeller.
Working principle of the present invention: after diversion is filled it up with the pump housing by water injection hole, actuating motor, two impeller rotations, the gas that retains in the intake pipe and the pump housing enters the self-priming impeller, under centrifugal action, diversion forms water ring around the self-priming impeller, because gas mixes with water generation air water simultaneously, and constantly increase on one side to osculum, and enter by this osculum and to extrude in the cavity, because flow velocity reduces suddenly and gas-liquid proportion difference, lighter gas is separated from gas-water mixture, gas is discharged by the exhaust port of pump cover, water after the degassing is flowed back in the self-priming impeller cavity by the aperture on the cut water plane under the pressure effect of gravity and impeller rotation, continues the air mixing that enters with intake pipe, so repeatedly, residual gas constantly reduces, and until whole discharges, sucts till the water, the intake pipe and the pump housing have been full of water, promptly finish the self-priming process.Thereupon, centrifugal impeller performance function, utilize the impeller of its high speed rotating, be formed centrally strong negative pressure therein, the water drainage of lower to eminence, is constantly entered the extrusion cavity with water by osculum, and waste pipe is defeated by in water transport by the exhaust port on the pump cover, meanwhile, the self-priming impeller is high speed rotating also, constantly water is transported to the extrusion cavity by osculum.
The present invention has following characteristics:
1, this centrifugal pump has the dual functions of self-priming pump and centrifugal pump, only needs to get final product filling with liquid in the pump before the centrifugal pump initial start-up, laborsaving, save time, easy to operate.
2, because self-priming impeller and centrifugal impeller are coaxial, water through two cavitys after, the water pressure of discharge is increased, lift increases, because centrifugal impeller is also stackable, therefore forms multistage centrifugal pump, this centrifugal lift of pump can reach more than 200 meters.The output quantity of pump proper functioning is the summation of two passage discharges, has greatly improved the efficient of pump, and its pump efficiency is compared with single pump, can improve more than six times.
3, the waste pipe of this centrifugal pump is provided with check valve, and motor stops, and check valve is in normally off, keeps in the pump a certain amount of water being arranged when making termination of pumping, when starting shooting once more, need not to add water, can directly drop into the work of drawing water.
4, existing self-priming pump generally only is suitable for clean water, if dispose of sewage or oil-based liquid, easily stop up, so its intake pipe bottom then need add filter, and this filter volume is greater than intake pipe, therefore is unsuitable for handling being similar to the such container of oil drum.The present invention then overcomes this defective, utilizes unshrouded impeller, and filter need not added in its intake pipe bottom, and its intake pipe can directly insert in the jack of oil drum, and realizes the processing to residual liquid in the oil drum (sewage or oil-based liquid).
5, the present invention is provided with liquid jetting device in the intake pipe bottom, can greatly carry high suction depth and lift, after tested, inhales journey and can reach more than 20 meters.
6, the present invention has compact structure, the characteristics reliable, that power consumption is low, cost is low operate steadily.This centrifugal pump is changed corresponding impeller according to different purposes, can be widely used in agricultural, industrial and mining enterprise, building site, hotel, family and sewage discharge, and the present invention can also be as pipeline mounted pump, to give pipe pressurizing or to be used for deep-well pump.
