Oil seal detection system

Abstract

The invention discloses an oil seal detection system, which consists of an air conditioning system and a measuring system, wherein a pedestal is fixed with a bracket slideway, a moving arm is arrangedin the bracket slideway, a post rod is in threaded connection in the moving arm, one end of the post rod contacts with an upright arm while the other end is provided with a rotary handle, one end ofthe moving arm far away from the rotary handle is fixed with a testing shaft which is sleeved with a jacket, the upper end of the jacket is fixed on a cross arm, a ripple flexible sealing member is arranged between the lower end of the jacket and the testing shaft, a ring flange is fixed at the upper end of the jacket, and the wall of the jacket is provided with an air inlet communicated with theair conditioning system. The oil seal detection system has the characteristics of measuring the pressure resistances of the oil seal at different offsets and the offsets of the oil seal at different air pressures, and having wide test application range, low test cost and simple structure.

Description

technical field [0001] The invention belongs to the technical field of oil seal detection equipment, and in particular relates to an oil seal detection system for an adjustable eccentric air pressure test. Background technique [0002] The oil seal is a mechanical component for sealing, also known as the rotating shaft seal ring. The friction part of the machine is oily when the machine is moving. In order to prevent the oil from leaking from the mechanical gap, the oil seal is used. However, with the development of mechanical technology, in addition to preventing oil leakage from mechanical gaps, it is also necessary to prevent water and chemical liquid leakage and prevent dust and sand from invading from the outside. Thereby avoiding the pollution of the environment caused by oil leakage and the damage to the machinery caused by the entry of sand and dust into the machinery. Therefore, the sealing ability of oil seals has become an important subject of research for variou...

AI Technical Summary

Problems solved by technology

The radial force measuring instrument only conducts a directional analysis of the sealing ability of the oil seal by measuring the holding force of the oil seal to the shaft, and cannot make an accurate judgment on the actual sealing ability of the oil seal

Although the durability test bench can accurately judge the actual sealing ability, the test period is too long and the cost is too high
