Reactor coolant pump water lubrication radial bearing test device and test simulation method

Abstract

The invention discloses a reactor coolant pump water lubrication radial bearing test device and a test simulation method. The invention discloses a reactor coolant pump water lubrication radial bearing test device. An elastic pin coupler can regulate the shaft centering, bears a big instantaneous overload and performs buffer vibration absorption; a single-row deep-groove ball bearing can bear the axial force under an operation working condition and can guarantee the smooth operation of the shafting in the high speed working condition; electromagnetic induction heating can realize the application of different stage temperature loads on the periphery of the bearing; a pressure pump and a regulation valve in a circuit can perform regulation on the bearing cooling water quantity, pressure and temperature; a water tank heater and a cooler regulate the bearing to inject the cooling water temperature; and the test device has the same working condition with the bearing in the reactor coolant pump. The invention is simple in structure, strong in adaptability, wide in application range and is applicable to the performance test of different stage water lubrication radial bearing.

Description

technical field [0001] The invention belongs to the technical field of equipment test devices, in particular to a reactor coolant pump water lubrication 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, reliability and durability of the bearing system directly affect the safety, reliability, stability and maintenance cycle of the main pump. The test bench directly determines the precision of the developed bearing. [0004] However, the main pump water-l...

Problems solved by technology

[0004] However, the main pump water-lubricated radial bearing technology (including the test bench) has been monopolized by a few developed countries such as Europe and the United States, which seriously restricts the development of new types of reactors in my country.
