Description

Technical Field

[0001] The utility model relates to the technical field of magnetic pumps, in particular to a bearing seat of a magnetic pump. Background Art

[0002] A magnetic pump is a centrifugal pump that uses magnetic force to achieve leak-free transmission of fluids. It has the advantages of being completely leak-free, highly efficient, and wear-resistant. As a fluid delivery device, magnetic pumps are widely used in many industries. They transmit power contactlessly through a magnetic field to drive the pump. This design enables the magnetic pump to ensure safety and environmental protection when transporting toxic, flammable, explosive, or precious liquids. The bearing seat is a component of the magnetic pump, which supports the pump shaft and maintains its correct position.

[0003] The existing bearing seat device is not convenient for adding lubricating oil to the position where the outer wall of the bearing body contacts the inner wall of the bearing seat. After the bearing body rotates for a long time, the friction between the outer side of the bearing body and the inner wall of the bearing will increase, which increases the friction loss of the bearing body and reduces the service life of the bearing body. It is also not convenient to replace the bearing body, so that the bearing seat can only be used once, which increases the cost of use and reduces the practicality of the device. Therefore, we propose a magnetic pump bearing seat to solve this problem. Utility Model Content
