Turbine oil, also known as turbine oil, usually includes steam turbine oil, gas turbine oil, hydraulic turbine oil and antioxidant turbine oil, etc. It is mainly used for turbine oil and sliding bearings , reduction gears, governors and hydraulic control systems of associated units. of lubrication. The main functions of turbine oil are lubrication, cooling and speed regulation.   Performance requirements   According to the functional characteristics of turbine oil, in order to ensure the safe and economical operation of the steam turbine unit, turbine oil must have: ① Good oxidation stability; ② Suitable viscosity and good viscosity-temperature properties; ③Good anti-emulsification; ④ Good rust and corrosion resistance; ⑤ Good anti-foaming and air release properties.   advantage   Due to the energy saving and high power characteristics of gas turbines , during operation, the lubricating oil is affected by high-heat surfaces, mixed with air (flue gas), pumped and circulated at a considerable rate, and used under high pressure. Therefore, gas turbines are required The oil has better high-temperature oxidation stability and wear resistance than steam turbine oil.   Note on usage   When using turbine oil, attention should be paid to: ① Prevent gas leakage, water leakage, and electric leakage of the turbine unit as much as possible; ② Control the return oil temperature below 65°C; ③ Regularly cut water and release impurities from the oil tank to keep the oil clean and free from water, rust, Sediment and other pollution.   Maintenance measures   In order to extend the service life of oil products, the maintenance of oil during operation should be strengthened. The following preventive measures can be taken: ① Add T501 antioxidant; ② Add T746 anti-rust agent; ③ Remove mechanical impurities and oil in the oil at any time to ensure that Ensure system cleanliness.   Oil change index   Our country has promulgated the L-TSA turbine oil oil change indicator SH/T0636-96; the ammonia-resistant turbine oil oil change indicator SH/T0137-92 and the ship turbine oil oil change indicator GJB3714-89; in addition, GB7596-87 and GB/ T9939-86 respectively stipulates relevant turbine oil quality monitoring items and indicators in the operation of the power sector and the chemical fiber and fertilizer industry.
