Description

Technical Field

[0001] The utility model relates to the technical field of floating oil seals, in particular to a floating oil seal sealing detection device. Background Art

[0002] Floating oil seal is a common name for floating seal, which is a kind of mechanical seal in dynamic seal. It is particularly suitable for harsh working environments such as coal powder, mud, water vapor, etc., and has super sealing performance. It is mainly used in low-speed and heavy-load occasions, and has been widely used in coal mining machinery, such as bulldozer walking mechanism, scraper conveyor head (tail) sprocket assembly, etc.; the advantages of floating oil seal include wear resistance, automatic compensation after end face wear, reliable operation, simple structure, etc. Floating oil seal is mainly composed of fixed ring, floating ring, spring and sealing device, etc.; its working principle is: when the equipment shaft rotates, lubricating oil is injected into the packaging cavity; due to a certain friction between the equipment shaft and the floating oil seal, the floating ring always keeps in contact with the equipment shaft; in During the relative movement between the floating ring and the shaft, the lubricating oil is pumped to the outside of the shaft through the gap of the packaging cavity to form an oil film; the contact between this oil film and the shaft can form a lubricating oil seal to block external air and impurities from entering the equipment and prevent lubricating oil leakage; the spring of the floating oil seal enables the floating ring to adapt to shaft deformation and axial displacement caused by other factors. The floating oil seal sealing detection device is usually used to test the sealing performance of the floating oil seal under specific conditions to ensure that it can effectively prevent the leakage of liquid or gas during operation; this detection device combines electronic technology with mechanical transmission, can provide accurate loading speed and force measurement range, and has high accuracy and sensitivity for load and displacement measurement and control.

[0003] At present, with the existing floating oil seal sealing detection device, after the detection is completed, workers usually wait for the material to be received at the material feeding frame at the material feeding place. If the workers keep waiting for the material to be received, it will not only affect their own work efficiency, but also increase a certain labor cost. After a long time, the workers themselves will inevitably become distracted, causing the oil seal to fall to the ground after the detection, thus affecting its service life. Therefore, a floating oil seal sealing detection device is proposed to solve the above problem. Utility Model Content
