The oil filter is the main component of the steam turbine. Then, what are the types of the oil filter of the steam turbine?
The main spare parts of steam turbine oil filter function is to filter hydraulic oil filtration equipment, mainly composed of shell and filter core. Generally, the hydraulic oil often contains granular impurities, which will cause wear of the hydraulic components relative to the moving surface, slide valve stuck, choke orifice, and greatly reduce the reliability of the system. It is necessary to install a certain precision oil filter in the system to ensure the normal operation of the hydraulic system.
There are mainly mesh filter on the market, line gap filter, paper filter, sinter filter; The mesh type oil filter is surrounded by a very porous plastic or metal cylindrical skeleton, wrapped in a layer or two layers of copper wire mesh, the filtration accuracy depends on the number of layers of copper mesh and mesh size; Gap type oil filter with steel wire or aluminum wire wrapped in the outer shell of the cylindrical skeleton to form the filter element, relying on the tiny gap between the copper wire filter mixed with the liquid impurities; Paper oil filter its filter core is made of plain or corrugated phenolic resin or wood pulp microporous filter paper, the paper core around the framework made of tin-coated iron with holes, in order to increase strength; Sinter type oil filter, its filter element is made of metal powder sintering, the use of micro pores between particles to block the impurities in the oil through. The filter element can withstand high pressure, good corrosion resistance, high filtration accuracy, suitable for high pressure and high temperature hydraulic system requiring fine filtration.
The above is the main content of what types of steam turbine oil filters are.
