Mesh, and the both ends of filtering screen are bent to form flange laterally, is provided with a tie rod on the pump housing, tie rod is by screen pack
In the flange of cover is coated on, the inwall of the outer wall of the flange and the tie rod is mutually closely packed together.
In the filtration of above-mentioned deep well pump, two annular gear edges spaced apart, ring are formed in the water inlet joint
Shape gear also forms the annular brace platform for positioning the filtering screen between, and the filtering screen is centered around annular brace
The periphery of platform, and the two sides of filtering screen are limited at described two annulars and kept off along interior.
In the filtration of above-mentioned deep well pump, the two sides of the filtering screen keep off edges with described two annulars respectively
It is abutted together.
In the filtration of above-mentioned deep well pump, the two sides of the filtering screen keep off edges with described two annulars respectively
Between gap be present.
In the filtration of above-mentioned deep well pump, a breach stretched into for the tie rod is offered in the water inlet joint,
Two outer walls of the tie rod and the inwall of breach fit, and a fixture are also associated with the water inlet joint, fixture is by described in
In one end of tie rod is coated on.
In the filtration of above-mentioned deep well pump, the part that the fixture envelopes tie rod is respectively provided with round and smooth mistake
Cross face.
In the filtration of above-mentioned deep well pump, the filter mesh has the first filter mesh group and the second screen pack
Hole group, the first filter mesh group and the second filter mesh group are spaced.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
Two flange of filtration are coated on internal and the annular gear edge with water inlet joint and annular by using tie rod
Supporting table is defined to the both sides of filtering screen, and such filtering screen its fixed structure while being fixed all conceals
The inside of tie rod and water inlet joint, outside is not exposed at, such fixed structure is just not easy to be destroyed, and effectively increases the life-span,
Also the rounder and more smooth overall structure for making deep well pump is also not present it more attractive in appearance while at each position of other fixed structure
Sharp position.

Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings,
As Figure 1-3, a kind of filtration of deep well pump, including the pump housing 1 and water inlet joint 2, water inlet joint 2 are connected to the pump housing
1 side, and water inlet 3 is offered in water inlet joint 2；The periphery of the water inlet joint 2 is surrounded with filtering screen 4, filtering screen 4
Surface forming have some filter mesh, and the both ends of filtering screen 4 are bent to form flange 6 laterally, are set on the pump housing 1
A tie rod 7 is equipped with, the flange 6 of filtering screen 4 is coated on interior, the inwall of the outer wall of the flange 6 and the tie rod 7 by tie rod 7
Mutually it is closely packed together.Two annulars gear spaced apart is formed in the water inlet joint 2 along 2a, annular gear between 2a along being also molded
There is the annular brace platform 2b for positioning the filtering screen 4, the filtering screen 4 is centered around annular brace platform 2b periphery,
And the two sides of filtering screen 4 are limited at described two annular gears along 2a.Filtering screen 4 is centered around annular brace platform 2b
On, and two annular gears are limited at along 2a, the flange 6 of filtering screen 4 is further coated on inside by tie rod 7,
So, filtering screen 4 is just coated on inside by tie rod 7 and water inlet joint 2, is like one overall from profile, not bright
The place of aobvious connection, extraneous factor is difficult that the structure is had an impact, during much time using, filtering screen 4 it is steady
It is qualitative to be guaranteed, so as to add the service life of filtering screen 4, reduce the expense of maintenance.
In the filtration of above-mentioned deep well pump, the two sides of the filtering screen 4 are kept off with described two annulars respectively
It is abutted together along 2a.
In the filtration of above-mentioned deep well pump, the two sides of the filtering screen 4 are kept off with described two annulars respectively
Along gap between 2a being present.
As shown in figures 1 and 3, in the filtration of above-mentioned deep well pump, one is offered in the water inlet joint 2 and supplies institute
State and draw 7 breach 9 stretched into, the inwall of two outer walls and breach 9 of the tie rod 7 fits, is also associated with the water inlet joint 2
One end of the tie rod 7 is coated on interior by one fixture 8, fixture 8.The end of tie rod 7 can be coated on by fixture 8
It is interior, enhance the intensity for the fixed structure of filtering screen 4, while by the sharp part in the end of tie rod 7 be coated in after,
Make the overall structure of deep well pump more attractive in appearance and round and smooth, in the absence of sharp part, another security gets a promotion.
As shown in figure 5, in the filtration of above-mentioned deep well pump, the part that the fixture 8 envelopes tie rod 7 is equal
With round and smooth transition face 8a.
As shown in fig. 6, in the filtration of above-mentioned deep well pump, the filter mesh has the first filter mesh group 5a
It is spaced with the second filter mesh group 5b, the first filter mesh group 5a and the second filter mesh group 5b.Due in straight line
The filter mesh of upper arrangement is excessively intensive and close, often influences the strainability of filtering screen 4 so that the magazine such as weeds is very
Easily it is blocked on filtering screen 4, is spaced the filter mesh group arranged and then solves this problem.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection model of the present utility model according to this
Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model
