Description

Technical Field

[0001] This utility model relates to the field of shaft seal testing technology, specifically a shaft seal wear resistance testing device. Background Technology

[0002] A shaft seal is a sealing element used to seal rotating or reciprocating shafts. It relies on the elastic lip of the seal to fit tightly against the shaft surface, generating a certain radial pressure on the contact surface to form a sealing surface and prevent liquids, gases or dust from leaking along the shaft surface.

[0003] After a shaft seal is installed on a shaft, the shaft will inevitably rub against the seal due to frequent rotation or reciprocating motion. Therefore, the seal must have strong wear resistance; otherwise, it will break and fail to perform its normal sealing function. Based on this, the wear resistance of the seal needs to be tested during production. Currently, the wear resistance test for shaft seals is generally conducted by manually grinding with abrasive tools such as files, and then the wear condition of the seal is visually observed by the staff.

[0004] The tests conducted by manual polishing and visual observation by staff have too many uncertainties, making the test results lack objectivity and accuracy. During manual polishing, it is impossible to guarantee the polishing force and polishing time for different parts of the sealing ring, resulting in inconsistent wear on different parts of the sealing ring.
