[0002] Mechanical seal is a common sealing technology used to prevent fluid or gas leakage in rotating or reciprocating mechanical devices. It usually consists of a friction fit between two contacting surfaces and an elastic element. The background of mechanical seals can be traced back to the early industrial revolution, when the operating speed and working conditions of mechanical equipment became increasingly demanding, and traditional packing seals began to show some limitations. Mechanical seals are a better solution due to their reliability and durability. Mechanical seals usually consist of a connecting part between a rotating shaft and a stationary housing. Common designs include a sealing ring on the rotating shaft and a sealing seat on the fixed housing. With this configuration, the mechanical seal can effectively prevent liquid or gas leakage while reducing friction and wear. However, the motor equipment on the market now generally adopts a closed structure that is difficult to dismantle, cumbersome to assemble, and inefficient.

The utility model arranges a sealing ring between the front cover and the rear cover of the motor, and semi-sealing ring grooves for placing the sealing ring are respectively arranged on the connection surfaces of the front cover and the rear cover, and finally the front cover and the rear cover are fixed by bolts. Such a sealing method makes the motor casing have a longer service life and better sealing performance, and can effectively protect the iron core in the casing and prevent the iron core from rusting. However, the above-mentioned motor sealing structure is complicated in structure, and it is very troublesome to disassemble and assemble, and the efficiency is low.
