Lip seal test experiment table

Abstract

The invention relates to a lip seal test experiment table, which comprises a T-shaped groove platform, wherein the T-shaped groove platform is provided with an alternating-current motor, and the alternating-current motor is fixedly provided with a shaft sleeve. An oil chamber is installed on the shaft sleeve and is connected with a static torque sensor through a key, and the right end of the static torque sensor is put into a connecting flange through key connection. An oil spur is sheathed onto the shaft sleeve, and the right side of the shaft sleeve is provided with a plastic end cover. An oil limiting chamber is fixedly arranged on the T-shaped groove platform through bolt connection, and the bottom of the oil limiting chamber is provided with an oil leak hole. A lip-shaped seal ring is installed into the oil chamber. The lip seal test experiment table can inspect the function of the lip-shaped seal ring and the feasibility and the reliability of key components under simulation of the actual condition, and a seal performance test of the seal ring under the working condition is realized. A research for expanding the test range of the inner diameter of the seal ring is realized, and a research of the disassembly process and method of the shaft sleeve is realized. A research of the influence of temperature on the seal effect is realized, and the lip seal test experiment table mainly measures the temperature change in a contact area of the shaft sleeve and the seal ring and an oil supply chamber. The lip seal test experiment table can conduct experiments to a plurality of tested seal rings at the same time.

Description

technical field [0001] The invention relates to a test bench for testing the comprehensive performance of sealing elements, in particular to a lip seal test bench. Background technique [0002] Whether the mechanical equipment can operate normally and whether the performance can be performed well is closely related to the design of the sealing structure and the sealing performance of the sealing element. If the seal fails, the loss caused by the leakage of the working medium or lubricating fluid is very alarming, which not only increases the friction, wear and power consumption of the machine, shortens the working life of the machine, but also causes environmental pollution and corrosion of equipment due to leakage. and working environment. More serious also can catch fire and explode because of this, cause the safety accident of personal, equipment. Therefore, carrying out research on sealing technology has become one of the key research projects in the current technical ...

AI Technical Summary

Problems solved by technology

[0003] At present, there is still a lack of effective technical means for testing the performance of lip seals. There are two commonly used methods: one is to use a general friction and wear testing machine to conduct tribological tests on sealing materials, mainly to test the friction coefficient of materials. , wear resistance and other tribological properties are far from the actual use of the sealing element, so this test method cannot reflect the leakage prevention ability of the sealing element under actual working conditions, nor can it judge the processing and assembly quality of the sealing element; therefore, If the sealing ring is applied to the actual working system only based on the results obtained from this test, it is likely to cause serious adverse effects on the machinery and equipment; the other is to use bench experiments to simulate actual working conditions and measure Leakage

However, the leakage is only one of the comprehensive performance indicators of the sealing ring, so this experimental method cannot comprehensively evaluate the performance of the sealing ring
