Abstract
The invention relates to the technical field of centrifugal pump accessories, in particular to a centrifugal pump cover. According to the technical scheme, the centrifugal pump cover comprises a pump cover body, a shaft hole is formed in the central of the pump cover body, a shaft hole base is arranged on the periphery of the shaft hole, a plurality of divergent reinforcing ribs are arranged on the outer side of the shaft hole, mounting holes and through holes are formed in the pump cover body, and the pump cover body comprises a pump cover inner layer and a pump cover outer layer which are coaxially arranged in a sleeving manner; a reinforcing part is arranged between the pump cover inner layer and the pump cover outer layer, and the pump cover inner layer, the pump cover outer layer and the reinforcing part are welded into a whole in a high-frequency manner through brazing filler metal filling. The centrifugal pump cover has the beneficial effects that the reinforcing part is arranged between the pump cover inner layer and the pump cover outer layer and is an I-shaped pressing-resisting beam, due to design of the I-shaped pressing-resisting reinforcing part, the whole strength and pressure resistance of the pump cover can be improved, weight cannot be increased too much, and in addition, the reinforcing part can achieve the heat transmission and heat dissipation effects.
Description
Technical field
The present invention relates to a kind of centrifugal pump accessory technical field, more particularly, to a kind of centrifugal pump cover.
Background technology
Centrifugal pump is to make the centrifugal force that water produces come work using impeller rotation, and water pump is before activation it is necessary to make pump
It is full of water in shell and suction hose, then start motor, make pump shaft impeller and water do high speed rotary motion, water is in centrifugal force
Under effect, it is thrown out of impeller foreign aid, the pressure pipe road flowing to inflow water pump through pump case.Pump cover is the critical piece of centrifugal pump,
Existing pump cover, structure is simple, insufficient strength, and service life is not long, needs often to change.Therefore it should provide a kind of new
Technical scheme solves above technical problem.
Content of the invention
The purpose of the present invention is：For above-mentioned deficiency, provide a kind of a kind of rational in infrastructure, good centrifugal pump pump of using effect
Lid.
For achieving the above object, the technical solution used in the present invention is：
A kind of centrifugal pump cover, including pump cover main body, the center of described pump cover main body has the axis hole installed for pump shaft,
The periphery of described axis hole is boss, and described axis hole and boss are coaxially disposed, and the outside of described axis hole is provided with many in divergent shape
Individual reinforcement, one end of described reinforcement is connected to axis hole outer, and the other end is connected with the correspondence position of boss, described pump cover
Main body is provided with installing hole and through hole, and described pump cover main body includes coaxially sheathed pump cover internal layer and pump cover outer layer, described pump cover
It is provided with reinforcement between internal layer and pump cover outer layer, high using filling solder between described pump cover internal layer, pump cover outer layer and reinforcement
Frequency welds, and makes pump cover internal layer, pump cover outer layer and reinforcement integral.
Further technical scheme is：
Described reinforcement is the anti-press beam of I shape.
The diameter of described installing hole is less than the diameter of through hole.
Due to the application of technique scheme, the present invention compared with prior art has the advantage that：
The centrifugal pump cover of the present invention, is provided with reinforcement between internal layer pump cover and outer layer pump cover, and reinforcement is I-shaped
The anti-press beam of type, the design of I shape reinforcement against pressure, bulk strength and the resistance to pressure of pump cover not only can be strengthened, and will not increase
Plus too many weight, in addition, this reinforcement may also operate as transmitting heat, the effect of radiating.
Brief description
Accompanying drawing 1 is present configuration schematic diagram.
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
Strong muscle, 5, reinforcement, 6, installing hole, 7, through hole.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
As shown in figure 1, as first embodiment of the present invention, a kind of centrifugal pump cover, including pump cover main body 1, described
The center of pump cover main body 1 has the axis hole 2 installed for pump shaft, and the periphery of described axis hole 2 is boss 3, described axis hole 2 and axle
Hole seat 3 is coaxially disposed, and the outside of described axis hole 2 is provided with multiple reinforcements 4 in divergent shape, and one end of described reinforcement 4 is connected to
Axis hole 2 outer, the other end is connected with the correspondence position of boss 3, and described pump cover main body 1 is provided with installing hole 6 and through hole 7, institute
State pump cover main body 1 and include coaxially sheathed pump cover internal layer 1-1 and pump cover outer layer 1-2, described pump cover internal layer 1-1 and pump cover outer layer 1-
It is provided with reinforcement 5, using filling solder ratio-frequency welding between described pump cover internal layer 1-1, pump cover outer layer 1-2 and reinforcement 5 between 2
Connect, make pump cover internal layer 1-1, pump cover outer layer 1-2 and reinforcement 5 integral.
Preferably as second embodiment, the present embodiment is the restriction further to embodiment one, described reinforcement 5
For the anti-press beam of I shape.
Preferably as the 3rd embodiment, the present embodiment is also the restriction further to embodiment one, described installing hole
6 diameter is less than the diameter of through hole 7.
The above is the preferred embodiment of the present invention it is noted that for those skilled in the art
For, on the premise of without departing from principle of the present invention, some improvement can also be made or replace, these improve or replace
Should be regarded as protection scope of the present invention.
