Description

Technical Field

[0001] The utility model relates to the field of bearing body structures, in particular to a bearing body structure for adjusting internal flow noise of a pump group. Background Art

[0002] Currently, the impeller seal ring commonly used in centrifugal pumps typically consists of a front impeller seal ring and a rear impeller seal ring. The impeller generates high-pressure and low-pressure areas during operation. The seal rings prevent the flow of liquid from the high-pressure area to the low-pressure area. Therefore, it is necessary to consider how to effectively control the internal flow noise of the pump unit during liquid flow. Therefore, it is necessary to design a bearing body structure that is simple in structure, easy to manufacture, and can also reduce the internal flow noise of the pump unit.

[0003] The existing bearing body structure for regulating the internal flow noise of the pump group is usually provided with a sealing ring and the bearing body is embedded into the pump body. The bearing body is usually installed at the rear ring of the impeller of the pump group. When the pump body is working, it can prevent the water from flowing back inside the pump body, thereby generating a large flow noise and affecting the use of the device.

[0004] As for the existing bearing body structure for regulating the internal flow noise of the pump group, it only embeds a group of bearing bodies at the rear ring of the impeller inside the pump body. The effect of absorbing and reducing the vibration and flow noise generated when the pump body is working is weak, and the use effect of the device cannot be achieved. In addition, the sealing ring installed inside will generate unstable flow force, and will form certain pressure pulsation and flow noise, which will increase the vibration and noise of the pump group, thereby reducing the effective working power of the pump and affecting the normal use of the device. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a bearing body structure for adjusting the internal flow noise of a pump group, so as to solve the technical problem of high flow noise when the pump group is working.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a bearing body structure for adjusting the internal flow noise of a pump group, comprising a sliding bearing seat, a gasket groove is provided on one side of the sliding bearing seat, a fixing through hole is provided in the gasket groove, a sliding bearing body is sleeved inside the sliding bearing seat, and an inner through groove is provided on one side of the sliding bearing body.

[0007] By adopting the above technical solution, the technical problem of large flow noise during operation of the pump group is solved. A sliding bearing body is provided, multiple sets of side grooves are opened on one side of the sliding bearing body, and multiple sets of limit blocks are provided on one side of the sliding bearing seat. The side grooves and the limit blocks are coupled with each other, and resin glue is filled between the side grooves and the limit blocks to ensure the sealing and stability of the device. At the same time, the shock absorption and buffering properties of the sliding bearing body itself made of PEEK material can absorb and disperse vibration energy, thereby reducing the vibration and noise of the pump group and increasing self-lubrication. The bearing body utilizes the embedded structure of the PEEK material bearing body, which can effectively reduce the friction loss between the impeller and the fluid during rotation, further improve the utilization efficiency of the pump, and at the same time reduce the wear of the impeller and extend its service life. The water-lubricated bearing body using PEEK material can also replace the sealing ring of conventional material, and also minimize the vibration and noise of the pump group.

[0008] The utility model is further configured such that an annular protrusion is provided inwardly inside the sliding bearing seat, and one side of the sliding bearing body is in close contact with the annular protrusion.

In addition, the multiple groups of fixing through holes can effectively enhance the fixing effect and prevent the sliding bearing seat from falling off.

[0012] The present invention is further configured such that a plurality of limit blocks are provided inside the sliding bearing seat, a plurality of side grooves are provided on one side of the sliding bearing body, and the side grooves are aligned with the limit blocks.

[0013] By adopting the above technical solution, multiple sets of limit blocks are arranged inside the sliding bearing seat, and multiple sets of side grooves are arranged on one side of the sliding bearing body. By sleeved the limit blocks into the side grooves, a limit effect is exerted on the sliding bearing body to prevent the sliding bearing body from rotating.

[0014] The utility model is further configured such that the width of the limit block provided inside the sliding bearing seat is smaller than the width of the side groove provided on one side of the sliding bearing body, and resin glue is filled between the limit block and the sliding bearing body.

[0015] By adopting the above technical solution, the limit block is sleeved into the side groove, and resin glue is filled between the limit block and the sliding bearing body, which can ensure the sealing and stability of the device.

[0016] The present invention is further configured such that a plurality of groups of inner through grooves are provided inside the sliding bearing body, and the inner through grooves are formed in a hemispherical shape.

[0017] By adopting the above technical solution, by providing multiple groups of inner grooves inside the sliding bearing body, and the inner grooves are provided in a hemispherical shape, the contact area between the inner grooves and the water coolant can be increased, thereby enhancing the cooling effect of the water coolant on the sliding bearing body.

[0018] The utility model is further configured such that the sliding bearing body is configured to be made of PEEK material, and two groups of lifting holes are opened on one side of the sliding bearing seat.

[0019] By adopting the above technical solution, the friction loss between the impeller and the fluid during rotation can be effectively reduced, the utilization efficiency of the pump can be further improved, and at the same time, the wear of the impeller is reduced and the service life of the impeller is extended.

By coupling the side grooves and the limit blocks with each other and filling resin glue between the side grooves and the limit blocks, the sealing and stability of the device are ensured. At the same time, the shock absorption and buffering properties of the sliding bearing body itself made of PEEK material can absorb and disperse vibration energy, thereby reducing the vibration and noise of the pump group and increasing self-lubrication. The bearing body utilizes the embedded structure of the PEEK material bearing body, which can effectively reduce the friction loss between the impeller and the fluid during rotation, further improve the utilization efficiency of the pump, and at the same time reduce the wear of the impeller and extend the service life of the impeller.
