Test device for simulating intrusion of particulate matter into rotating lip seal in real time under sandstorm

Abstract

The invention provides a test device for simulating the intrusion of particulate matter into a rotating lip seal in real time under sandstorm, including a rotary lip seal system, a sandstorm environment simulation system and a visual monitoring system. In the rotary lip seal system, one end of a medium cavity is provided with lip seal, the other end of the medium cavity is connected with a variable speed variable frequency motor, a hollow transparent shaft is placed in the medium cavity, one end of the hollow transparent shaft is in elastic contact with the edge of the lip seal, and the other end of the hollow transparent shaft is fixed on a saddle support on a base. Sandstorm outlets of the sandstorm environment simulation system are located in one end of the hollow transparent shaft and the seal surface of the lip seal, and the seal surface is located within the visual range of the visual monitoring system. The test device has the advantages of low cost and convenient installation, can simulate the sealing performance and the service life of the rotating lip seal in the sandstorm environment, can simulate the damage process of the rotating lip seal more effectively in the sandstorm environment, and can timely monitor the process of intrusion of environmental particulate matter into the rotating lip seal.

Description

technical field [0001] The invention relates to a rotary lip seal test technology for simulating work in a sandstorm environment, in particular to a test device for real-time monitoring of the intrusion of environmental particles into a rotary lip seal. Background technique [0002] Sealing devices are key core components in the equipment manufacturing industry, and often directly determine the performance, quality and reliability of major equipment and main engines. Once the seal fails, it will cause lubricant deterioration or leakage, increase machine wear, power consumption and shorten its service life, cause environmental pollution or corrosion of equipment, and cause serious accidents such as fire and explosion or even personal safety. Rotary shaft lip seal (referred to as lip seal) is widely used in aerospace, transportation, petrochemical and biopharmaceutical fields due to its compact structure, low price and reliable performance. It relies on working pressure (inclu...

Problems solved by technology

[0005] In order to overcome the deficiency that the existing technology cannot realize the sealing performance test by immersing particles into the rotary lip seal in a sandstorm environment, the present invention provides a test device for real-time monitoring of particulate matter intrusion into a rotary lip seal in a simulated sandstorm environment. The system truly simulates the actual wind and sand environment and is combined with the visual monitoring system and data acquisition and control system to comprehensively evaluate the sealing performance and service life of the rotary lip seal, which can more realistically simulate the damage process of the rotary lip seal damaged by the wind and sand erosion environment, and Real-time monitoring of the process of environmental particles intruding into the rotary lip seal
