Sealing detection device and method for electric rotating connector

Abstract

The invention provides a sealing detection device and method for an electric rotating connector. The detection device comprises a sealing box which is used to contain liquid, the sealing box is internally provided with a fixation structure which fixes a casing of the electric rotating connector, a transmission shaft is assembled at the wall of the sealing box in a sealing and rotating manner, the transmission shaft includes a power output end and a power input end, the power output end is in transmission connection with a rotating shaft of the electric rotating connector so that the rotating shaft rotates relative to the casing, and rotation torque is input via the power input end. When the electric rotating connector is fixed to the fixation structure, the transmission shaft can drive the rotating shaft of the electric rotating connector to rotate relative to the casing, the rotation state of the electric rotating connector during use can be simulated, thus, the sealing performance of the electric rotating connector in the rotation state can be tested, and the reliability of the electric rotating connector is ensured.

Description

technical field [0001] The invention relates to a sealing detection device, in particular to a sealing detection device and a detection method of an electric rotary connector. Background technique [0002] Electrical rotary connectors are widely used in power equipment, and whether the electrical rotary connectors are safe and reliable determines the normal operation of the power system. After the electrical rotary connector is produced and assembled, its performance generally needs to be tested to determine whether the electrical rotary connector is qualified and whether it can be put into use. The traditional detection method is generally to put it directly into the pressure ax to test the sealing performance under a certain hydrostatic pressure. The multiple conductive slip rings fixed on the shaft realize the conductive connection in the rotating state through sliding cooperation with the fixed contact wire of the housing. The traditional sealing test cannot detect the ...

Problems solved by technology

The traditional detection method is generally to put it directly into the pressure ax to test the sealing performance under a certain hydrostatic pressure. The multiple conductive slip rings fixed on the shaft realize the conductive connection in the rotating state through sliding cooperation with the fixed contact wire of the housing. The traditional sealing test cannot detect the dynamic sealing performance of the electric rotary connector in use, and it cannot be accurately determined. Whether its dynamic sealing performance is reliable or not leaves a certain safety hazard for later use
