Abstract

The invention relates to a bidirectional-loading double-turning water-lubrication thrust bearing testing apparatus with a pretightening force. The testing apparatus comprises a motor, a loading part, and a testing part. The loading system employs two sets of independent hydraulic loops and is provided with two sets of loaded piston cylinders and two sets of loaded thrust bearings; loading is carried out on two directions simultaneously and the loads are adjusted respectively and can change according to different designated rules, thereby simulating the complicated operation condition of the real machine. The testing part mainly includes a testing bearing water tank, two sets of testing thrust bearing support systems, two sets of testing thrust bearing bushes, two sets of thrust plates, and one set of flywheels; and springs are installed in the testing thrust bearing support systems and pretightening is carried out on the testing thrust bearing bushes. Therefore, effective performance testing is carried out on the two sets of testing bearings. The loading part and the testing part of the apparatus are independent to each other; the installation and maintenance become simple; and performance testing can be carried out on a thrust bearing with any lubrication medium in any support mode. The provided apparatus can be applied to various fields like the thrust bearing of the nuclear main pump motor and the like.

Description

technical field [0001] The invention relates to a bidirectional loading and double steering water lubricated thrust bearing test device with pretightening force. Background technique [0002] The thrust bearing is one of the most important components in the main pump motor of nuclear power, and its working performance is directly related to the safe operation of the unit. With the improvement of the operating reliability of nuclear power equipment, the requirements for thrust bearings are also higher. The AP1000 main pump motor in large-scale third-generation nuclear power plants uses imported bearings. In the process of independently developing the CAP1400 main pump motor, it involves the development and verification of bearings. Bearings need to be adjusted for working conditions. Contents of the invention [0003] The purpose of the present invention is to disclose a test device which is easy to install and maintain, and can effectively test and verify the performance...
