Description

Technical Field

[0001] The utility model relates to the technical field of corrosion and fatigue resistance testing structures for pump core parts, in particular to a corrosion and fatigue resistance testing device for full PP pump core parts. Background Art

[0002] The pump core is a component of the oil pump. Specifically, the pump core is mainly composed of a stator, rotor, blades, pressure side plate, side plate and seals. Its performance and lifespan determine the operating effect and sustainability of the oil pump. Corrosion and fatigue resistance tests are required during the production and processing of pump core parts. During the corrosion resistance test, the pump core parts are generally placed in a corrosive test fluid, and the surface of the pump core is immersed or adhered to test the corrosion time. During the fatigue resistance test, the pump core is continuously pressed to test the number of presses.

[0003] The existing pump core corrosion and fatigue resistance testing device has certain drawbacks when used. The traditional pump core corrosion and fatigue resistance testing device can only test the corrosion resistance and fatigue resistance of the pump core separately, and cannot test them at the same time. The pump core is not easy to take out from the corrosive test liquid storage tank. It is easy to shake on the workbench surface during the test, which will also cause the workbench to shake, and the mass of the pump core is easily adsorbed to the punch head, affecting the test effect.
