Background technique

The engine is a machine that can convert other forms of energy into mechanical energy. When the engine is working, the moving parts have a certain interaction force. Due to the high-speed relative motion, the surface of the parts will inevitably produce friction, resulting in wear. Therefore , in order to reduce wear, reduce frictional resistance, and prolong service life, there must be a lubrication system on the engine, and lubricating oil is usually used, which brings some problems. Since the generator runs at high speed for a long time, the lubrication system The sealing structure is easily damaged and causes oil leakage, which not only causes environmental pollution and increases the cost, but also may damage the internal parts of the generator due to the leakage of lubricating oil, so the seal needs to be replaced frequently. The traditional method is to manually compress the seal. If it enters the seal cavity or the crankshaft, it will cause the seal to flang, the service life is not long, and the replacement is too frequent.
