Abstract

The invention provides a method for detecting the abrasion loss of a sealing element. The method at least comprises the following steps of adding a tracing element to the sealing element; putting thesealing element into a machine table to be put into actual use or carrying out a bench test; extracting oil liquid of the sealing element in actual operation of a machine table or in a bench test to obtain an oil liquid sample; and detecting the concentration of the tracer element in the oil sample through oil, and calculating to obtain the wear degree of the sealing element. According to the method for detecting the abrasion loss of the sealing element, the abrasion degree of the sealing element is obtained before the sealing element is abraded and loses efficacy, and economic losses and environmental pollution caused by sealing failure of the sealing element are avoided.

Description

technical field [0001] The invention relates to the technical field of wear detection of seals, in particular to a method for detecting wear of seals. Background technique [0002] Seal wear failure is one of the main failure forms that lead to the shutdown of mechanical equipment. According to incomplete statistics, in hydraulic seals, the failure caused by wear accounts for about 84% of the total seal failure. Sealing element wear, medium leakage, etc. will lead to major national economic losses and environmental pollution damage. If the degree of wear of the sealing element can be detected in an early stage and adjusted in time, the major economic losses and environmental pollution caused by the failure of the seal can be effectively reduced. [0003] At this stage, there is a lack of effective means for seal wear and failure detection. At present, the failure research on seals is limited to the failure cause analysis after seal failure, which belongs to "after-event res...
