Description

Technical Field

[0001] This utility model relates to the field of magnetic pump technology, and in particular to an auxiliary structure for mounting a magnetic pump impeller. Background Technology

[0002] A magnetic drive pump is a type of pump that uses magnetic force for transmission. Its main advantage is that it can transport various liquids without leakage. The impeller is one of the core components of a magnetic drive pump, directly affecting the pump's performance and efficiency. The impeller generates centrifugal force through rotation, pushing the liquid from the pump inlet to the outlet, thus achieving fluid transport.

[0003] In existing magnetic pumps, the impeller is removed from the main shaft during installation and fixed to the main shaft with bolts. Because the bolts are not protected or restrained, they come into contact with the water flow when the main shaft drives the impeller to rotate, which can easily cause damage or loosening and affect the stability of the impeller installation. In view of this, this solution proposes an auxiliary structure for the installation of magnetic pump impellers to solve the above problems. Utility Model Content
