Abstract

This invention provides a pump guide bearing, comprising: a guide bearing body; a through water groove and multiple blind water grooves formed within the guide bearing body, the through water groove being disposed in the middle of the guide bearing; and a throttling sleeve fitted over the outside of the guide bearing, the throttling sleeve comprising a base and a throttling groove disposed at one end of the base. The above-mentioned pump guide bearing has a simple structure. By forming multiple blind water grooves within the guide bearing body and using a throttling sleeve for cooling, the lubricating cooling water does not need to completely pass through the guide bearing body, thereby saving the flow area and achieving the effect of throttling the lubricating cooling water, thus reducing the operating cost of the water pump.

Description

A pump guide bearing

technical field

The invention relates to the field of pump structures, in particular to a guide bearing for pumps.

Background technique

When the circulating water pump is running, lubricating cooling water needs to be connected to the pump guide bearing to lubricate and cool the pump guide bearing. The lubricating cooling water is directly discharged into the pump suction tank through the lower guide bearing and cannot be recycled. When the pump is running, it needs 24 hours of uninterrupted water supply, and consumes a lot of cooling water every day.

The existing pump guide bearing has water grooves in the bearing, and each water groove is straight. After the lubricating water flows through the lower guide bearing from top to bottom, it merges with the medium conveyed by the pump, resulting in waste of lubricating water.

SUMMARY OF THE INVENTION

In view of this, an object of the present invention is to provide a guide bearing for a pump with a significant throttling effect.

A guide bearing for a pump, comprising:

The guide bearing body; the guide bearing body is provided with a conducting water groove and a plurality of blind channel water grooves, and the conducting water groove is arranged in the middle of the guide bearing;

A throttling sleeve is sleeved on the outside of the guide bearing, and the throttling sleeve includes a base body and a throttling groove arranged at one end of the base body.

In one embodiment, the plurality of blind channel water tanks are symmetrically distributed around the conducting water tank.

In one of the embodiments, the lengths of the plurality of blind channel water tanks are different.

In one of the embodiments, the throttling groove is composed of a throttling groove body and a channel.

In one embodiment, the throttling groove body is embedded on the base body.

In the above-mentioned pump guide bearing, the structure is simple. By opening a plurality of blind channel water grooves in the guide bearing body and using a throttling sleeve for cooling, the lubricating cooling water does not need to pass through the guide bearing body completely, thereby saving the flow area and achieving throttling. The function of lubricating cooling water, thereby reducing the operating cost of the water pump.

Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

A guide bearing 100 for a pump includes a guide bearing body 1 , a conducting water groove 2 , a plurality of blind channel water grooves 3 and a throttle sleeve 4 .

Specifically, in one embodiment, the conducting water trough 2 and the plurality of blind channel water troughs 3 are all provided in the guide bearing body 1 , wherein the conducting water trough 2 is provided with a conducting water trough 2 and a plurality of blind channel water troughs 3 . Specifically, in one embodiment, the plurality of blind channel water tanks 3 are symmetrically distributed with the conducting water tank 2 as the center. In one of the embodiments, the lengths of the plurality of blind channel water tanks 3 are different.

A throttling sleeve 4 is sleeved outside the guide bearing body 1 , and the throttling sleeve 4 includes a base body 5 and a throttling groove 6 provided at one end of the base body 5 .

In one embodiment, the throttling groove 6 is composed of a throttling groove body and a channel 7 . In one of the embodiments, the throttling groove body is embedded on the base body 5 .

In the above-mentioned pump guide bearing, the structure is simple. By opening a plurality of blind channel water grooves in the guide bearing body and using a throttling sleeve for cooling, the lubricating cooling water does not need to pass through the guide bearing body completely, thereby saving the flow area and achieving throttling. The function of lubricating cooling water, thereby reducing the operating cost of the water pump.

Finally, it should be noted that the above-mentioned embodiments are only specific implementations of the present invention, and are used to illustrate the technical solutions of the present invention, but not to limit them. The protection scope of the present invention is not limited thereto, although referring to the foregoing The embodiment has been described in detail the present invention, those of ordinary skill in the art should understand: any person skilled in the art who is familiar with the technical field within the technical scope disclosed by the present invention can still modify the technical solutions described in the foregoing embodiments. Or can easily think of changes, or equivalently replace some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should be covered in the present invention. within the scope of protection. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
