Hydraulic seal comprehensive experiment table and experiment method

Abstract

The invention discloses a hydraulic seal comprehensive experiment table and an experiment method, the hydraulic seal comprehensive experiment table comprises a seal experiment oil cylinder, a rotary seal experiment box, a telescopic dragging oil cylinder, a dragging driving hydraulic power loop, a loading hydraulic power loop and a high temperature experiment heating oil supply device, the loadinghydraulic power loop is connected with the seal experiment oil cylinder through a hydraulic pipeline; the oil path of the tested sealing element is controlled through the on-off of the stop valve; reciprocating motion of the telescopic dragging oil cylinder is controlled through the stop valve or rotary motion of the sealing experiment box driven by the rotary motor is controlled; the high-temperature experiment heating oil supply device is connected with the sealing experiment oil cylinder and the rotary sealing experiment box through hydraulic pipelines, and on-off of supply of heating oilis controlled through a stop valve. Various actual working conditions can be simulated to detect the sealing performance, the tribological performance and the sealing piece manufacturing quality, tests of high-temperature, high-speed, high-pressure, impact and other items and dynamic performance change curves with continuously adjustable pressure can be met at the same time, and very high comprehensive experiment capacity and an excellent energy-saving effect are achieved.

Description

technical field [0001] The invention relates to an experimental platform with comprehensive performance, in particular to an energy-saving hydraulic sealing comprehensive experimental platform and an experimental method suitable for testing hydraulic sealing components and hydraulic sealing systems. Background technique [0002] Sealing components and the sealing system composed of them are important components to prevent leakage in the hydraulic system. Their sealing performance and anti-wear performance will have an important impact on the performance, reliability and life of the entire hydraulic system. The development of new and old sealing elements of various models and specifications and their combinations lack effective technical means and methods for the experimental detection of different application conditions. Usually chemical tests are carried out at the stage of raw materials, and physical tests use friction and wear testing machines, hardness testers, tensile t...

AI Technical Summary

Problems solved by technology

This type of test often needs to simulate as much as possible to meet the actual working conditions, and it is necessary to compare various combinations, including seals of different structures and materials of different sizes, products of different manufacturers for the same seal, and different working conditions to deal with the sealing system. Combined research tests and comparative tests, long-term reliability life tests need to consume a lot of power, and high-temperature tests will also cause damage to the experimental device system, and sometimes intensified tests are required to accelerate the test process, etc., the existing experimental equipment It is also difficult to complete, therefore, there is an urgent need for a comprehensive test bench and method that can complete the above functions
