[0002] A seawater pump is a pump specially designed to handle seawater and is suitable for a variety of scenarios, such as fish tanks, aquariums, ships, and marine aquaculture. In order to be suitable for the marine environment, compared with ordinary water pumps, seawater pumps are not only corrosion-resistant and wear-resistant, but also have a more stable water flow rate, which can ensure the service life of the water pump. During the production process of seawater pumps, the performance of seawater pumps needs to be tested to ensure the quality of seawater pumps.

[0003] Most existing water pump testing devices use a rigid structure to fix the water pump and then conduct the test. However, the water pump will vibrate during the test. This fixing method can easily cause friction between the surface of the water pump and the clamping device, which can easily cause damage to the surface of the water pump. At the same time, long-term vibration can easily damage the transmission structure of the clamping device, which not only affects the stability of the clamping, but also shortens the service life of the clamping device. After searching, it was found that the technical solution provided by the utility model with application number CN202322641244.5 also has the above-mentioned problems. Utility Model Content
