Abstract
The utility model discloses a pump casing of a step structure. The pump casing is characterized by comprising a pump casing main body and a runner. A fluid outlet is formed in the lateral wall in the pump casing main body, the runner is formed in the outer lateral wall of the pump casing main body and is communicated with the fluid outlet, a water inlet is formed in the bottom of the pump casing machine body, the water inlet is of a step structure, and the step structure comprises a small hole at the bottom and a groove arranged above the hole. The pump casing of the step structure has the advantages that a cavity structure in a water pump is changed into the step structure, so that a guiding function on fluid in a cavity is achieved, impact of fluid in a pump body is reduced, and the service life of the pump body is prolonged.
Description
Technical field
The utility model relates to the pump assembly field, specifically, specially refers to a kind of pump case that adopts stepped construction.
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, 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 technical problem that the utility model solves can realize by the following technical solutions:
A kind of pump case that adopts stepped construction is characterized in that: comprise pump case main body and runner, the sidewall of described pump case body interior offers fluid output, and described runner is installed on the outer side wall of pump housing main body and is communicated with described fluid output; The bottom of described pump housing main body offers water inlet, and described water inlet adopts stepped construction, and described stepped construction comprises the aperture of bottom and the groove that is arranged at the aperture top.
Further, described runner is connected as a single entity by integral structure and pump case main body.
Further, on described runner, be provided with bolt connecting hole, described bolt connecting hole is distributed in the outlet end of runner.
Compared with prior art, the beneficial effects of the utility model are as follows:
Simple in structure, design ingeniously, use instead as stepped construction 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 plan view of the pump case that Fig. 1 is employing stepped construction described in the utility model.
Number in the figure explanation: 100. pump case main body 110. fluid output 120. water inlet 200. runner 210. 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 case that adopts stepped construction described in the utility model, comprise pump case main body 100 and runner 200, the sidewall of described pump case main body 100 inside offers fluid output 110, and described runner 200 is installed on the outer side wall of pump housing main body 100 and is communicated with described fluid output 110; The bottom of described pump housing main body 100 offers water inlet 120, and described water inlet 120 adopts stepped construction, and described stepped construction comprises the aperture of bottom and the groove that is arranged at the aperture top.
It is pointed out that described runner 200 is connected as a single entity by integral structure and pump case main body 100, by adopting this kind of structural design, guaranteed the structural strength of whole pump case, extended working life.
In addition, it should be noted that on described runner 200 and be provided with bolt connecting hole 210, described bolt connecting hole is distributed in the outlet end of runner.By adopting above-mentioned structural design, facilitate installment and debugging in actual use of the present utility model.
Compared with prior art, the beneficial effects of the utility model are as follows:
Simple in structure, design ingeniously, use instead as stepped construction 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.
