Description
Technical Field
The utility model relates to a bearing field especially relates to a water pump bearing housing.
Background
In industrial production, fluid media conveyed by the water pump have the characteristics of high temperature, strong corrosivity, gas content and the like, so that the water pump shaft sleeve made of cast iron has a serious cavitation phenomenon. Under the combined action of factors such as cavitation, solid particle scouring in liquid medium, sewage corrosion, thermal expansion and cold contraction, the water pump is easy to generate abnormal sound, vibration and leakage; seriously, even the water pump breaks the shaft and stops the fault; generally, a water pump needs to be stopped and overhauled once after running for about 2 months, a large amount of spare parts and overhauling force are wasted, and a normal production plan is seriously influenced; in addition, the traditional water pump shaft has poor flow guide effect and is not beneficial to conveying fluid media to the impeller; therefore, it is necessary to provide a water pump shaft sleeve to solve the above problems.
Therefore, a new technique is sought to solve the above problems.
Disclosure of Invention
The utility model aims at: a bearing sleeve of a water pump is provided.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a water pump bearing housing, includes the bearing housing body, the bearing housing body includes first festival section and second festival section, be equipped with the bearing groove between first festival section and the second stage, first festival section internal diameter is greater than second festival section internal diameter, first festival section surface is equipped with the baffle, second stage is equipped with mechanical sealing device outward.
An elastic sliding sleeve is arranged in the bearing groove.
And a fastening groove is formed outside the bearing sleeve body.
And an anti-corrosion layer is arranged outside the elastic sliding sleeve.
In the above technical scheme, compared with the prior art, the beneficial effect that reaches is: an elastic sliding sleeve is arranged in the bearing sleeve body, so that the bearing is convenient to fix; the design of fastening groove is favorable to the reinforcement of bearing housing body and fastening groove, and the design of anti-corrosion coating can make its corrosion resistance.
Drawings
Fig. 1 is a schematic structural diagram of a first embodiment of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
The first embodiment is as follows:
as shown in fig. 1, the utility model discloses a water pump bearing housing, including bearing housing body 1, bearing housing body 1 includes first festival section 2 and second festival section 3, be equipped with bearing groove 4 between first festival section 2 and the second stage 3, 2 internal diameters of first festival section are greater than 3 internal diameters of second festival section, 2 surfaces of first festival section are equipped with baffle 5, second stage 3 is equipped with mechanical seal device 6 outward.
An elastic sliding sleeve 7 is arranged in the bearing groove 4.
And a fastening groove 8 is formed outside the bearing sleeve body 1.
And an anti-corrosion layer 9 is arranged outside the elastic sliding sleeve 7.
In the above technical scheme, compared with the prior art, the beneficial effect that reaches is: an elastic sliding sleeve 7 is arranged in the bearing sleeve body 1, so that a bearing can be fixed conveniently; the design of the fastening groove 8 is beneficial to the reinforcement of the bearing sleeve body 1 and the fastening groove 8, and the anti-corrosion layer 9 can be designed to have corrosion resistance.
