Special oil filtering device for steam turbine capable of removing impurities and oil filtering method

Abstract

The invention relates to a special oil filtering device for a steam turbine and an oil filtering method. The oil filtering device is mainly used for treating the turbine oil of a generator set and canquickly and effectively remove moisture, gas and impurities in the oil. The oil filtering device comprises a water tank (1), a vacuum tank (2), a heater (3), a condenser (4) and a vacuum pump (5), wherein the water tank is connected with the vacuum pump through a water pipe; the top of the vacuum pump is connected with the condenser through an air inlet pipe (6); the side surface of the vacuum pump is connected with the condenser through a condenser discharging pipe (7), the bottom of the condenser is provided with a water storage tank (8), the lower part of the water storage tank is connected with an air discharging pipe (9) and a water discharging pipe, the upper part of the condenser is connected with the vacuum tank through a pipeline, a vacuum meter (11) is arranged on the pipeline,the invention relates to the oil filtering device of the steam turbine.

Description

Technical field: [0001] The invention relates to a special oil filtering device and an oil filtering method for a steam turbine capable of removing impurities. Background technique: [0002] The oil filter device of the steam turbine is mainly used for the treatment of the turbine oil of the generator set, which can quickly and effectively remove the moisture, gas and impurities in the oil. Improve the quality of oil, ensure the normal operation of the unit adjustment and lubrication system, and extend the maintenance cycle of the unit. [0003] The currently used steam turbine oil filter device contains a lot of water in the filtered oil, and the gas pumped out by the vacuum pump contains too much water vapor. In the vacuum pump, the vacuum oil is lower than the oil level line. The device will absorb a lot of impurities. Invention content: [0004] The object of the present invention is to provide a special oil filter device and oil filter method for steam turbines capa...

AI Technical Summary

Problems solved by technology

[0003] The filter oil of the steam turbine oil filter device currently used contains a lot of water and too much water vapor in the gas pumped out by the vacuum pump. In the vacuum pump, the vacuum oil is lower than the oil level line. Due to the use of After a long time, there will be a lot of water content, and the seals at the joints will leak, and the oil filter will absorb a lot of impurities.
