Problems solved by technology

[0003] In order to overcome the following problems in the prior art, the static test of the existing large-scale hydraulic damper includes two aspects of low-speed frictional resistance performance and locking performance. One percent, using the same set of test equipment to complete the low-speed friction resistance performance and locking performance test, due to the relatively large range of load changes, the detection accuracy of the equipment cannot meet the requirements of product test accuracy at the same time, seriously affecting the accuracy of the test results, and There is also a huge waste of energy during the test

Abstract

The invention provides a method and a device for test of a large hydraulic damper. A large hydraulic damper block performance test bench and a large hydraulic damper low-speed friction resistance performance test bench are employed to respectively perform test of the block performance and low-speed friction resistance performance so as to guarantee the test accuracy of the block performance and low-speed friction resistance performance and improve the accuracy of test results, through cooperation of arrangement of a damper bracket of the block performance test bench and a holder of a low-friction performance test bench and arrangement of two speeds of a large hydraulic damper low-friction performance test bench hydraulic system, the difficulty when the large hydraulic damper is employed for test is reduced, the operation is simple, the usage is convenient, the test efficiency of the large hydraulic damper is improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of testing hydraulic dampers, in particular to a testing method and equipment for large hydraulic dampers. Background technique [0002] The hydraulic damper is a device used for shock resistance and shock absorption. According to different occasions, the performance requirements of the hydraulic damper are also different. The large hydraulic damper is used for the support and vibration reduction of the main nuclear power equipment. It is a major safety equipment. One end is installed on the main equipment, and the other end is installed on the fixed body. The two ends can produce relative movement. There are two main requirements for its performance: 1. Low-speed friction resistance performance; 2. Lock-up and post-lock performance. For large hydraulic dampers, the performance of its products depends on the performance of the test equipment and the test The level of technology, for example, the patent "CN2...
