Description

Technical Field

[0001] This utility model relates to the technical field of magnetic pump bearing housings, specifically a magnetic pump bearing housing. Background Technology

[0002] A magnetic drive pump is a centrifugal pump that uses magnetic force to achieve leak-free fluid transfer. It has advantages such as being completely leak-free, highly efficient, and wear-resistant. As a fluid transport device, magnetic drive pumps are widely used in many industries. It transmits power without contact through a magnetic field, thereby driving the pump. This design ensures safety and environmental protection when transporting toxic, flammable, explosive, or valuable liquids. The bearing housing is a component of the magnetic drive pump, which supports the pump shaft and keeps it in the correct position.

[0003] The existing publication number CN222576956U discloses a magnetic pump bearing housing, belonging to the field of magnetic pump technology. It includes a lower bearing housing, with an upper bearing housing positioned on top of the lower bearing housing. A connecting pipe is fixedly installed on the top of the upper bearing housing, and a sealing cap is provided on the top of the connecting pipe. A sealing ring is provided at the bottom of the sealing cap. The top of the outer side of the connecting pipe and the bottom of the outer side of the sealing cap are threadedly connected to the same connecting sleeve. An upper annular groove is fixedly formed in the inner cavity of the upper bearing housing, and a lower annular groove is fixedly formed in the inner cavity of the lower bearing housing. This design facilitates the addition of lubricating oil to the contact points between the outer wall of the bearing body and the inner walls of the upper and lower bearing housings, improving the rotational efficiency of the bearing body, extending its service life, and allowing for quick disassembly and assembly of the upper and lower bearing housings. This facilitates bearing body replacement by operators and increases the versatility of the device.

[0004] While existing technologies enable quick bearing replacement, the mounting point between the bearing housing and the pump casing is prone to loosening, resulting in significant noise. Therefore, we propose a magnetic pump bearing housing. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: A plug is installed on the side of the fixed seat away from the bearing housing body, and a sealing gasket mounting groove is opened on the side of the bearing housing body located on the plug. A sealing gasket is installed in the sealing gasket mounting groove. The sealing gasket is located between the fixed seat and the pump housing, which to a certain extent prevents the bearing housing from loosening, thereby avoiding noise caused by loosening; The plug has an annular groove, and an annular sealing ring is installed on the plug in the annular groove. After the plug is inserted into the pump housing of the magnetic pump, the annular groove of the plug is located in the pump housing. The annular sealing ring is installed in the annular groove, so that the plug and the pump housing are buffered by the annular sealing ring, which to a certain extent prevents the bearing housing from loosening, thereby avoiding noise caused by loosening.
