Jacking oil pump discharge filter DQ8302GAFH3.5C is mainly used at the outlet of the oil pump of the jacking device. The shaft-jacking device is an important part of the steam turbine unit. It plays the role of jacking the rotor when turning the engine to warm up and evenly cool down during the startup and shutdown of the unit. In order to ensure the stable operation of the jacking oil system and filter out impurities in the oil, filter element DQ8302GAFH3.5C is used. The simple filtration process is that after the fluid enters the filter, its impurities are blocked by the filter, and the clean fluid is discharged from the filter outlet. When cleaning is needed, just disassemble the filter cartridge, take out the filter element, and then put it in after cleaning. Therefore, the maintenance of filter element DQ8302GAFH3.5C is very convenient.
The jacking oil system in the steam turbine generator unit adopts two-stage oil filter, which effectively maintains the cleanliness of the system. The oil pump adopts the imported constant pressure variable flow plunger pump, and the inlet and outlet pipelines of the oil pump are equipped with pressure switches to timely remind the filter screen of blockage. Duplex filters are used at the inlet and outlet, one for operation and one for standby, so that the filter element can be replaced without shutdown.
Detailed parameters of filter element DQ8302GAFH3.5C:
1. Product characteristics: corrosion resistance;
2. Applicable object: oil products;
3. Working temperature: - 20~+80 ℃
4. Material: stainless steel
High-pressure oil jacking device is not used many times and for a long time each year, so the maintenance should focus on the leakproofness of the pipeline system, focusing on the monitoring and maintenance during the normal operation of the steam turbine, repairing as leakage occurs, and regularly replacing the filter element DQ8302GAFH3.5C according to the differential pressure indication of the oil filter.
