Steam turbines include drive steam turbines and industrial power generation turbines. There are power station steam turbines, industrial steam turbines and marine steam turbines according to different routes. The working principle of the steam turbine is that a certain temperature and pressure gas enters the nozzle, expands and accelerates in the nozzle, and the thermal energy of the gas is converted into kinetic energy. The gas impinges on the moving blade at high speed, and the moving blade drives the impeller to rotate, thereby converting the kinetic energy into the rotating mechanical energy of the main shaft. Steam turbine oil and other lubricating grease products are used in many places on steam turbines. Lubricating grease is actually the blood of the device, and the quality of the blood also reflects the current state of the device.
