Abstract
The utility model relates to a water pump which comprises a pump body, a pump base, a pump shaft and an impeller. The pump body is provided with a water inlet and a water outlet, the pump base is fixedly connected to the pump body, the pump shaft driven by the motor is arranged on the pump base in a penetrated mode, and the impeller is arranged on the pump shaft. A water drainage hole is formed in the lateral face of the bottom of the pump body, a water drainage plug is installed in the water drainage hole, a water injection hole is formed in the upper portion of the pump body, and a water injection plug is installed in the water injection hole. According to the water pump, the water injection hole and the water drainage hole are formed in the pump body, the inner wall of the water pump can be conveniently washed, vestigial media are conveniently removed, corrosion of a part of media to the inner wall of the water pump is effectively prevented, the rusting condition of the inner wall of the water pump is reduced, and the water pump has the advantages of being simple in structure and convenient to manufacture.
Description
Technical field
The utility model relates to a kind of water pump, belongs to water pump manufacturing technology field.
Background technique
Water pump is being widely used in daily life, agricultural and industrial production; Water pump is after use finishes, and people are normally shelved on whole water pump on one side after deenergization, if things go on like this, and due to meeting residual fraction water or other media in water pump; Therefore the appearance rust staining that water pump inwall can be in various degree, more has even, and part has corrosive medium can produce corrosive action to the impeller of water pump and pump shaft, cause reduce the working life of whole water pump.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and the water pump that a kind of antirust ability is strong, be convenient to cleaning is provided.
The purpose of this utility model is achieved by the following technical solution: comprise have water intake and water outlet the pump housing, be fixedly connected on pump seat on the pump housing, be located on described pump seat by being provided with impeller on motor-driven pump shaft, pump shaft; Described pump housing bottom sides offers a spilled water hole, and a drain plug is installed on this spilled water hole; Described pump housing top offers a water injection hole, and a water filling plug is installed on this water injection hole.
As preferably, described spilled water hole be oriented substantially horizontal; Described water injection hole be oriented vertical direction.
As preferably, described drain plug and water filling plug are made by rubber.
As preferably, described pump housing inwall is also provided with a coating for protection against corrosion.
The beneficial effects of the utility model are: water injection hole and spilled water hole are set on the pump housing, are convenient to water pump inwall clean and get rid of residual medium, effectively prevent the corrosion of part medium to water pump inwall, reduce the situation that water pump inwall gets rusty; There is feature simple in structure, easy to make.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: as shown in Figure 1, comprise have water intake 4 and water outlet 5 the pump housing 1, be fixedly connected on pump seat 2 on the pump housing 1, be located on described pump seat 2 by being provided with impeller 6 on motor-driven pump shaft 3, pump shaft 3; The described pump housing 1 bottom sides offers a spilled water hole 7, and a drain plug 8 is installed on this spilled water hole 7; The described pump housing 1 top offers a water injection hole 9, and a water filling plug 10 is installed on this water injection hole 0.
Described spilled water hole 7 be oriented substantially horizontal; Described water injection hole 9 be oriented vertical direction.
Described drain plug 8 and water filling plug 10 are made by rubber.
The described pump housing 1 inwall is also provided with a coating for protection against corrosion, further improves the antirust and antiseptic power of the pump housing.
The described pump housing 1 bottom is provided with a spilled water hole 7; One drain plug 8 is installed on described spilled water hole 7, after water pump is stopped using, in the pump housing, can leaves a small amount of water or other media, rest on for a long time pump body, can cause that the pump housing gets rusty; If water pump transmission is to have corrosive medium, can corrode the pump housing, impeller, destroy pump body structure, therefore need in time the medium remaining in the pump housing to be discharged.
On the described pump housing 1, be provided with a water injection hole 9; One water filling plug 10 is installed on described water injection hole 9, has facilitated while using water pump for the first time, in the pump housing, fill with liquid medium; Meanwhile, when water pump changes fed sheet of a media or water pump is cleaned, also can be from water injection hole directly toward water filling in the pump housing, simple to operation.
Long-time use after water pump, has a certain amount of pollutant and is deposited in the pump housing 1 bottom, and water injection hole and spilled water hole are used simultaneously, are convenient to water pump inwall to clean.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model is also not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
