Description
Technical field
The utility model is related to a kind of centrifugal pump accessory technical field, more particularly to a kind of centrifugal pump cover.
Background technology
Centrifugal pump is to be rotated using impeller and make the centrifugal force that water is produced come work, and water pump is before activation, it is necessary to make pump
Water is full of in shell and suction hose, then starts motor, pump shaft impeller and water is done high speed rotary motion, water is in centrifugal force
Under effect, impeller foreign aid is thrown out of, the pressure pipe road for flowing into water pump is flowed to through pump case.Pump cover is the critical piece of centrifugal pump,
Existing pump cover, simple in construction, insufficient strength, service life is not grown, it is necessary to often change.Therefore, it should provide a kind of new
Technical scheme solves above technical problem.
The content of the invention
The purpose of this utility model is：For above-mentioned deficiency, there is provided a kind of a kind of rational in infrastructure, the good centrifugation of using effect
Pump pump cover.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of centrifugal pump cover, including pump cover main body, the center of the pump cover main body are provided with the axis hole installed for pump shaft,
The periphery of the axis hole is boss, and the axis hole and boss are coaxially disposed, and the outside of the axis hole is provided with many in divergent shape
Individual reinforcement, one end of the reinforcement is connected to axis hole outer, the correspondence position connection of the other end and boss, the pump cover
Main body is provided with mounting hole and through hole, and the pump cover main body includes the pump cover internal layer and pump cover outer layer being coaxially arranged, the pump cover
Reinforcer is provided between internal layer and pump cover outer layer, it is high using filling solder between the pump cover internal layer, pump cover outer layer and reinforcer
Frequency is welded, and makes pump cover internal layer, pump cover outer layer and reinforcer integral.
Further technical scheme is：
The reinforcer is I-shaped anti-press beam.
The diameter of the mounting hole is less than the diameter of through hole.
Due to the application of above-mentioned technical proposal, the utility model has the following advantages that compared with prior art：
Centrifugal pump cover of the present utility model, is provided with reinforcer between internal layer pump cover and outer layer pump cover, and reinforcer is
I-shaped anti-press beam, the design of I-shaped reinforcer against pressure can not only strengthen the bulk strength and resistance to pressure of pump cover, and not
Too many weight can be increased, in addition, the reinforcer can also play a part of transmission heat, radiating.
Brief description of the drawings
Accompanying drawing 1 is the utility model structural representation.
In the figures above：1st, pump cover main body, 1-1, pump cover internal layer, 1-2, pump cover outer layer, 2, axis hole, 3, boss, 4 plus

Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
As shown in figure 1, as one embodiment of the present utility model, a kind of centrifugal pump cover, including pump cover main body 1,
The center of the pump cover main body 1 is provided with the axis hole 2 installed for pump shaft, and the periphery of the axis hole 2 is boss 3, the axis hole 2
It is coaxially disposed with boss 3, the outside of the axis hole 2 is provided with multiple reinforcements 4 in divergent shape, and one end of the reinforcement 4 connects
The outer of axis hole 2 is connected on, the other end is connected with the correspondence position of boss 3, the pump cover main body 1 is provided with mounting hole 6 and through hole
7, the pump cover main body 1 is included outside the pump cover internal layer 1-1 that is coaxially arranged and pump cover outer layer 1-2, the pump cover internal layer 1-1 and pump cover
Reinforcer 5 is provided between layer 1-2, using filling solder high frequency between the pump cover internal layer 1-1, pump cover outer layer 1-2 and reinforcer 5
Welding, makes pump cover internal layer 1-1, pump cover outer layer 1-2 and reinforcer 5 integral.
Preferably as second embodiment, the present embodiment is the further restriction to embodiment one, the reinforcer 5
For I-shaped anti-press beam.
Preferably as the 3rd embodiment, the present embodiment is also the further restriction to embodiment one, the mounting hole
6 diameter is less than the diameter of through hole 7.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of principle described in the utility model is not departed from, some improvement or replacement can also be made, these improvement
Or replacement also should be regarded as protection domain of the present utility model.
