The beneficial effect of the utility model is that the mechanical seal is cooled when the water pump is idling, and the heat generated by high-speed operation is conducted, which effectively increases the service life of the centrifugal water pump, and at the same time, the rotation speed of the water pump can be increased, thereby increasing the water output and improving the use efficiency of the water pump.

[0004] The existing idling-resistant centrifugal water pump has the following disadvantages. Since the existing equipment will shake during operation and the stability of the water pump is generally poor, it is easy to cause certain damage to the pipeline when the water pump shakes, which makes the equipment have certain limitations. Therefore, we propose a new type of idling-resistant centrifugal water pump. Utility Model Content
