shaft sleeve 125LY-33DZ-2 is a part of AC lubricating oil pump.
The AC lubricating oil pump 125LY-33DZ-2 is a specialized power equipment for the hollow side sealing circuit of the generator sealing oil system. Its main function is to deliver sealing oil to the air side sealing surface of the generator rotor, form an air side sealing oil film, and block the leakage of hydrogen gas inside the generator into the atmosphere. This pump has the characteristics of precise flow rate, stable pressure, and reliable operation. It can automatically adjust the output according to the pressure requirements of the air side sealing system, ensuring the stability of the air side sealing oil film. At the same time, taking away the heat from the sealing parts through oil circulation and protecting the sealing components is a key equipment to ensure the normal operation of the generator sealing oil system and prevent hydrogen leakage.
