Abstract
The utility model discloses a pump body of a vibrating type shield pump. The pump body of the vibrating type shield pump comprises a pump case which is of a cup-type structure. A circle of protrusion structures are arranged on the side surface of an inner cavity body of the pump case. A flange is arranged at the opening end of the pump case. A water outlet is formed in the position, close to the flange, of the inner cavity body of the pump case. A center hole is formed in the middle portion of the case top surface of the pump case. Water inlets are formed around the center hole. The number of the water inlets is at least two, and the water inlets are uniformly formed around the center hole. The pump body of the vibrating type shield pump is obvious in effects of increasing water inflow and water yield.
Description
Technical field
The utility model relates to a kind of water pump field, especially relates to a kind of pump housing that is applied to vibration-type shield pump.
Background technique
Vibration-type shield pump is widely used in treegarden irrigation, tall building water and traffic cleaning etc. in the market, but the inflow of the vibration-type shield pump pump housing and water-outlet quantity are important indicators estimating pump housing performance, in prior art, but but inflow and water-outlet quantity in order to improve the vibration-type shield pump pump housing, usually all adopt and increase water inlet and osculum, but although but adopt increase water inlet and osculum to increase inflow and water-outlet quantity, but the pump housing of the prior art is due to the size restriction of the pump housing, and this improvement can't reach good effect.
Summary of the invention
For the deficiencies in the prior art, but but the utility model provides the vibration-type shield pump pump housing of a kind of increase inflow and water-outlet quantity successful.
In order to realize above-mentioned effect, the utility model adopts following technological scheme:
A kind of vibration-type shield pump pump housing, comprise pump case, described pump case is cup type structure, be provided with a circle protruding structure on the side of the inner chamber body of pump case, an end of described pump case opening is provided with flange, is provided with osculum in described pump case inner chamber body near the position of flange, the shell end face central position of described pump case offers center hole, offer the water inlet around center hole, described water inlet is at least two, and is evenly distributed on around center hole.
Further, around described center hole, equally distributed water inlet is set to eight.
Further, the diameter of described water inlet be not less than pump case shell end face diameter 1/10.
Further, offer two grooves on the bottom surface of described flange, the arc length of every groove is not more than 1/4 of flange girth.
Further, described two grooves are evenly distributed on flange.
Technique scheme of the present utility model has the following advantages compared to existing technology:
a kind of vibration-type shield pump pump housing described in the utility model, due to the overall structure of having improved the pump housing, increased the equally distributed water inlet that is at least two around center hole, make inflow greatly improve, be provided with a circle protruding structure on the side of the inner chamber body of pump case, in the time of in water enters the pump housing, most of water can be pressed towards below protruding structure, make the pump body boost in pressure, make from the increased pressure of osculum water outlet, water-outlet quantity strengthens, two grooves of offering on the bottom surface of flange simultaneously, strengthened to a certain extent its sealability, guaranteed that this pump housing is installed in the Safety performance on motor.
For content of the present utility model is more likely to be clearly understood, the below is described in further detail the utility model according to specific embodiment of the utility model also by reference to the accompanying drawings.
Description of drawings
Fig. 1 is the structure principle chart of a kind of vibration-type shield pump pump housing of the utility model;
In figure, 1 is pump case, and 2 is flange, and centered by 3 the hole, and 4 is the water inlet, and 5 is osculum, and 6 is protruding structure.
Embodiment
Figure 1 shows that a kind of vibration-type shield pump pump housing, comprise pump case 1, described pump case 1 is cup type structure, but but in order to make increase inflow and water-outlet quantity successful, be provided with a circle protruding structure 6 on the side of the inner chamber body of pump case 1, one end of described pump case 1 opening is provided with flange 2, position at the close flange 2 of described pump case 1 inner chamber body is provided with osculum 5, the shell end face central position of described pump case 1 offers center hole 3, offer water inlet 4 around center hole 3, described water inlet 4 is at least two, and is evenly distributed on around center hole 3.
Around described center hole 3, equally distributed water inlet 4 is set to eight, the diameter of described water inlet 4 be not less than pump case 1 shell end face diameter 1/10, offer two grooves on the bottom surface of described flange 2,1/4, the two described groove that the arc length of every groove is not more than flange 2 girths is evenly distributed on flange 2 and is symmetrical set.
in the present embodiment, due to the overall structure of having improved the pump housing, increased the equally distributed water inlet 4 that is at least two around center hole 3, make inflow greatly improve, be provided with a circle protruding structure 6 on the side of the inner chamber body of pump case 1, in the time of in water enters the pump housing, most of water can be pressed towards protruding structure 6 belows, make the pump body boost in pressure, make from the increased pressure of osculum 5 water outlets, water-outlet quantity strengthens, two grooves of offering on the bottom surface of flange 2 simultaneously, strengthened to a certain extent its sealability, guaranteed that this pump housing is installed in the Safety performance on motor.
