Problems solved by technology
However, the current water-lubricated radial bearing test bench simulates the radial load of the rotor by pulling the rotor. Although it can simulate the operating performance of the rotor, it is easy to cause the seal in the test bench because the simulation test is carried out by dragging the rotor. The service life of parts is shortened, which increases the economic cost of the test and prolongs the development cycle of the test

Description
technical field [0001] The invention relates to the technical field of bearing tests for nuclear power plant reactor coolant pumps, in particular to a vertical water-lubricated radial bearing test device and a test simulation method thereof. Background technique [0002] In recent years, as people gradually realize the significance of the environment and energy saving to the sustainable development of human beings, the voice of developing new energy-saving and pollution-free products is getting higher and higher. Nuclear pumps have huge advantages in this regard, so water-lubricated bearings have great potential for development. [0003] In the main pump, the water-lubricated bearing is one of the key core components of the main pump. The design of the bearing system, the reliability and durability of the operation can directly affect the safety, reliability and stability of the main pump operation and the maintenance of the main pump. cycle. The bearing test bench can tes...
