The beneficial effects of the utility model are that can be quick clean with the log raft in the pump body.
Description
Technical field
The utility model relates to a kind of New type water pump.
Background technology
Water pump is conveying liquid or the machinery making fluid pressurization.It sends mechanical energy or other external energies of prime mover to liquid, liquid energy is made to increase, it is mainly used to carry liquid and includes water, oil, acid & alkali liquid, emulsion, suspended emulsion and liquid metal etc., it is possible to conveying liquid, admixture of gas and the liquid containing suspended solids.The technical parameter of pump performance has flow, suction, lift, shaft power, water-horse power, efficiency etc.；The types such as volume water pump, vane pump can be divided into according to different operation principles.Displacement pump is that the change utilizing its swept volume of a single chamber is to transmit energy；Vane pump is to utilize the rotary vane interaction with water to transmit energy, has the types such as centrifugal pump, axial-flow pump and mixed-flow pump.
When water pump does not uses, should be by the water emptying in pump and in pipeline, it is to avoid when environment temperature is relatively low, the water freezing in pump damages the pump housing, thorough for water emptying is needed the longer time by prior art.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of New type water pump, overcomes deficiency of the prior art.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: New type water pump, including the pump housing, the top of the described pump housing has pump priming mouth, on described pump priming mouth, there is three-way pipe, one end of described three-way pipe connects with described pump priming mouth, and two other port of described three-way pipe is respectively provided with sealing lid and emptying unit；
Described emptying unit includes bellows and cylinder, there is on the one side of described bellows air inlet and air outlet, described air outlet is through with described three-way pipe, it is respectively provided with check valve in described air inlet and described air outlet, another side relative with described air inlet on described bellows is open surface, has the contact internal walls of piston, the edge of described piston and described bellows in described bellows, described cylinder is positioned at outside described bellows, and the pistons end on described cylinder is connected with described piston；
In described pump priming mouth, there is valve.
Further, the one section of inboard wall of tube body connected with described bellows in described three-way pipe has and adds thermal resistance.
The utility model has the advantage that with good effect: owing to using technique scheme, can be quickly by the water emptying in the pump housing, simple in construction, and energy consumption is low.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
In figure: the 1-pump housing；2-pump priming mouth；3-three-way pipe；4-bellows；5-air inlet；6-cylinder.
Detailed description of the invention
As it is shown in figure 1, the utility model provides a kind of New type water pump, including the pump housing 1, the top of the pump housing 1 has pump priming mouth 2, having three-way pipe 3 on pump priming mouth 2, one end of three-way pipe 3 connects with pump priming mouth 2, and two other port of three-way pipe 3 is respectively provided with sealing lid (not shown) and emptying unit；
Emptying unit includes bellows 4 and cylinder 6, there is on the one side of bellows 4 air inlet 5 and air outlet, air outlet is through with three-way pipe 3, check valve (not shown) it is respectively provided with in air inlet 5 and air outlet, another side relative with air inlet 5 on bellows 4 is open surface, has piston (not shown) in bellows 4, the edge of piston and the contact internal walls of bellows 4, it is outside that cylinder 6 is positioned at bellows 4, and the pistons end on cylinder 6 is connected with piston；
In pump priming mouth 2, there is valve.
During pump priming, sealing lid and valve are opened, water is filled the pump housing 1, when water pump the most do not use need emptying time, can first by major part water discharge after open valve again, cover tightly sealing lid, starting cylinder 6 makes piston reciprocating in bellows 4, air enters in the pump housing 1 by the three-way pipe 3 that moves through of piston, increases air pressure in the pump housing 1 with this, thus reaches remaining hydraulic pressure goes out the pump housing 1 and dries up the purpose of the pump housing 1 inwall.
Have on the one section of inboard wall of tube body connected with bellows 4 in three-way pipe 3 and add thermal resistance (not shown), at low ambient temperatures, can open and add thermal resistance, make the air being blown in the pump housing 1 have certain temperature, be more favorable for drying up the remaining water in the pump housing 1.
Above embodiment of the present utility model is described in detail, but described content has been only preferred embodiment of the present utility model, it is impossible to be considered for limiting practical range of the present utility model.All impartial changes made according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
Claims (2)
1. New type water pump, it is characterized in that: include that the pump housing, the top of the described pump housing have pump priming mouth, described pump priming mouth has three-way pipe, one end of described three-way pipe connects with described pump priming mouth, and two other port of described three-way pipe is respectively provided with sealing lid and emptying unit；Described emptying unit includes bellows and cylinder, there is on the one side of described bellows air inlet and air outlet, described air outlet is through with described three-way pipe, it is respectively provided with check valve in described air inlet and described air outlet, another side relative with described air inlet on described bellows is open surface, has the contact internal walls of piston, the edge of described piston and described bellows in described bellows, described cylinder is positioned at outside described bellows, and the pistons end on described cylinder is connected with described piston；In described pump priming mouth, there is valve.
New type water pump the most according to claim 1, it is characterised in that: have on the one section of inboard wall of tube body connected with described bellows in described three-way pipe and add thermal resistance.
