Problems solved by technology

The steam turbine oil disclosed above has mainly anti-corrosion and anti-rust properties, and the extreme pressure and anti-wear properties are average due to the selection and addition content of extreme-pressure anti-wear agents. The stability is poor and the cooling performance is average, so it is not a qualified turbine oil
[0005] To sum up, due to the strict performance requirements of steam turbine oil, among various performances, there will be a phenomenon that one performance is highlighted and another performance is insufficient, that is, an effective balance cannot be achieved among various performances: the requirements Better extreme pressure anti-wear performance and lubricating performance, the viscosity of the oil will be lower, and the cooling performance and anti-emulsification performance will be affected; too many organic additives will also lead to unstable performance of the oil and high temperature stability. poor
