Abstract

The invention discloses a hydraulic damper sealing double-medium detection apparatus and a detection method thereof. The hydraulic damper sealing double-medium detection apparatus comprises an apparatus main body and further comprises a work module arranged inside the apparatus main body, and the work module comprises a hydraulic detection unit, an air pressure detection unit, a vacuum-pumping unit and a reversing valve; and the top portion of the apparatus main body is also provided with a detection work platform, a hydraulic damper is fixedly placed on the detection work platform, the work module is connected with an inner cavity of the hydraulic damper through the reversing valve, and by use of motion of the reversing valve, the hydraulic detection unit, the vacuum-damping unit or the air pressure detection unit can be respectively controlled to act on the hydraulic damper so that sealing performance of the hydraulic damper can be detected through a liquid medium and a gas medium. According to the invention, the accuracy of a detection result is guaranteed, the detection steps are simple and convenient, the detection time is shortened, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to a hydraulic shock absorber sealing performance detection device and a detection method thereof, in particular to a hydraulic shock absorber sealing performance double-medium detection device and a detection method thereof. Background technique [0002] With the rapid development of the new energy field, the pace of development of the wind power industry is accelerating, and the power of the unit is increasing, which also puts forward higher requirements for the overall performance of the unit system. In order to ensure the smooth operation of the transmission system of wind turbines, the traditional pure rubber shock absorber cannot meet the requirements of large damping at low frequencies, so hydraulic shock absorbers have been developed. The specially designed hydraulic shock absorber has a multi-layer rubber elastic structure, which can not only ensure the strength of the restrained load, but also play a quiet and shock-free...
