Abstract

The invention discloses a high-voltage adjustable bellows life testing device, which comprises a complete machine board and a bellows pipe. The four corners of the bottom of the complete machine board are respectively provided with anti-vibration sliders, and the top of the complete machine board is provided with rails. , the inside of the track is provided with a screw, and the top of the track is provided with a screw connecting plate, one side of the track is provided with a screw hand wheel, and a motor fixing plate is vertically arranged above the screw connecting plate, The present invention uses nitrogen as the high-pressure gas to carry out high-pressure and long-term detection on the metal bellows, which can effectively obtain the service life of the metal bellows, provide correct data for mass production, and solve the problem of using metal bellows in high-pressure thermostats Uncertain factors exist during the time, which improves the safety factor of the metal bellows; and the present invention uses nitrogen as the high-pressure gas, which reduces the cost of detecting the metal bellows.

Description

technical field [0001] The invention belongs to the related technical field of life testing of bellows in a high-pressure state, and in particular relates to a high-voltage adjustable bellows life testing equipment. Background technique [0002] The quality of the metal bellows depends on the stability of the trial, and the service life must meet the design requirements. It has not reached the service life measured under high pressure for a long time, and there are uncertain factors in the high-pressure thermostat. Effectively obtain the trial life of bellows and provide correct data for mass production. Contents of the invention [0003] The purpose of the present invention is to provide a high-voltage adjustable bellows life testing equipment to solve the problems that the metal bellows proposed in the background technology cannot measure the service life under high pressure, and there are uncertain factors when entering the high-pressure thermostat. [0004] In order t...
