Abstract
The utility model discloses a pump body of a layered structure. The pump body is of an integrated structure, a first connecting pump opening is formed in one end of the pump body, and a second connecting pump opening is formed in the other end of the pump body. The pump body is characterized in that a cavity in the pump body is divided into an upper cavity body and a lower cavity body by a metal blocking plate, the upper cavity body is communicated with the first connecting pump opening, and the lower cavity body is communicated with the second connecting pump opening. The pump body has the advantages of being simple in structure and ingenious in design. The cavity in the pump body is changed to be of a split structure, so that a guiding function for fluid in the cavity is generated, impact of the fluid in the pump body is reduced, and the service life of the pump body is prolonged.
Description
Technical field
The utility model relates to the pumping plant field, specifically, specially refers to a kind of pump housing that adopts hierachical structure.
Background technique
Water pump is the machinery of carrying liquid or making the liquid supercharging.It sends the mechanical energy of prime mover or other external energies to liquid, liquid energy is increased, be mainly used to carry liquid to comprise water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal etc., the liquid that also can carry liquid, gaseous mixture and contain suspended solids.The technical parameter of weighing pump performance has flow, inhales journey, lift, air horsepower, water-horse power, efficiency etc.; Can be divided into the types such as volume water pump, vane pump according to different working principles.Displacement pump is to utilize the variation of its swept volume of a single chamber to carry out transferring energy; Vane pump is to utilize the interaction of rotary vane and water to carry out transferring energy, and the types such as centrifugal pump, axial-flow pump and mixed flow pump are arranged.
In the prior art, the cavity of water pump inside often adopts integral structure, and in use inner current are larger, also larger to the internal impact power of the pump housing, easily shortens the working life of water pump.
The model utility content
The technical problem that the utility model actual demand solves is: the cavity of water pump of the prior art inside often adopts integral structure, in use inner current are larger, internal impact pressure to the pump housing is also larger, easily shortens the working life of water pump.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of pump housing that adopts hierachical structure, the described pump housing adopts integral structure, one end of the described pump housing has the first connection pumping hole, the other end of the pump housing has the second connection pumping hole, it is characterized in that: the cavity of described pump body is divided into upper cavity and lower chamber by metal baffle, described upper cavity is connected pumping hole and is communicated with first, described lower chamber is connected pumping hole and is communicated with second.
Further, described the first connection pumping hole is connected pumping hole and has the edge radially extended with second, offer some bolt connecting holes on described edge.
Further, the neutral position of described metal baffle has through hole.
Compared with prior art, the beneficial effects of the utility model are as follows:
Simple in structure, design ingeniously, use instead as split-type structural by the cavity body structure by water pump inside, thereby can produce rectified action to the fluid of inside cavity, reduce pump body fluid impact power, and then extended the working life of the pump housing.
The accompanying drawing explanation
The structural representation of the pump housing that Fig. 1 is employing hierachical structure described in the utility model.
The number in the figure explanation: 100. pump housings 110. first connect pumping hole 120. second and connect pumping hole 130. upper cavity 140. lower chamber 200. metal baffle 210. through hole 300. edge 310. bolt connecting holes.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Referring to Fig. 1, a kind of pump housing that adopts hierachical structure described in the utility model, the described pump housing 100 adopts integral structure, one end of the described pump housing 100 has the first connection pumping hole 110, the other end of the pump housing 100 has the second connection pumping hole 120, the cavity of the described pump housing 100 inside is divided into upper cavity 130 and lower chamber 140 by metal baffle 200, and described upper cavity 130 is connected pumping hole 110 and is communicated with first, and described lower chamber 140 is connected pumping hole 120 and is communicated with second.
It should be noted that, described the first connection pumping hole 110 is connected pumping hole 120 and has the edge 300 radially extended with second, offer some bolt connecting holes 310 on described edge 300, by adopting this kind of structural design, make the pump housing 100 to be connected with other assembly.
In addition, also it is pointed out that the neutral position of described metal baffle 200 has through hole 210, by adopting this kind of structural design, make between upper cavity 130 and lower chamber 140 and form runner.
Compared with prior art, the beneficial effects of the utility model are as follows:
Simple in structure, design ingeniously, use instead as split-type structural by the cavity body structure by water pump inside, thereby can produce rectified action to the fluid of inside cavity, reduce pump body fluid impact power, and then extended the working life of the pump housing.
Above demonstration and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
