Abstract

The invention relates to a method for improving steam turbine oil operation performances. The method solves the problem that based the prior art, only the de-emulsifier can improve demulsibility of steam turbine operation oil. Through utilization of 0.5 to 10wt% of an additive composition in steam turbine oil operation, the method solves the above problem and can be used for improving steam turbine oil operation performances, wherein the additive composition comprises: by weight, 0.05 to 10 parts of an antirust agent and 75 to 99.4 parts of base oil.

Description

technical field [0001] The invention relates to a method for improving the running performance of steam turbine oil. Background technique [0002] Steam turbine is also called turbine (Turbine), which is the key equipment for energy conversion in power generation equipment. A steam turbine is a rotary power machine that converts steam energy into mechanical work, and is one of the main equipment of a steam power plant. The structure and purpose of the gas turbine are similar to it. It is a thermal gas power machine that converts the thermal energy carried by the hot gas into rotating mechanical energy. The water turbine belongs to the turbo machinery in the fluid machinery, and it is a power machine that converts the energy of water flow into rotational mechanical energy. [0003] Steam turbines include drive steam turbines and industrial power generation steam turbines. According to different uses, there are power station steam turbines, industrial steam turbines and mari...
