Before replacing the hydraulic filter element of Volvo excavator, drain the original hydraulic oil, check the oil return filter element, oil suction filter element, and clean the system after the pilot filter element is overhauled and removed.
1. When replacing the hydraulic filter element of Volvo excavator, all hydraulic oil filter elements (oil return filter element, oil suction filter element, pilot filter element) must be replaced at the same time, otherwise it is equivalent to not changing.
2. Do not mix hydraulic oils of different labels and brands, because this may cause the hydraulic oil filter element to react and deteriorate and produce floccules.

3. Before refueling, the hydraulic oil filter element (oil suction filter element) must be installed first. The nozzle covered by the hydraulic oil filter element directly leads to the main pump. The entering of impurities will accelerate the wear of the main pump, and the pump will be beaten.
4. After adding oil, pay attention to the main pump to exhaust air, otherwise the whole vehicle will be temporarily inactive, the main pump will make abnormal noise (air sonic boom), and the cavitation will damage the hydraulic oil pump. The air exhaust method is to directly loosen the pipe joint on the top of the main pump and fill it up directly.
5. Regularly do oil testing. The hydraulic filter element of Volvo excavator is a consumable item, and it needs to be replaced immediately after it is usually blocked.
6. Pay attention to flushing the fuel tank and pipeline of the excavator system, and pass the fueling device with filter when refueling.
7. Do not let the oil in the oil tank directly contact the air, and do not mix the old and new oil, which is helpful to prolong the service life of the filter element.
Volvo excavator hydraulic filter replacement time
The filter element of Volvo excavator must be changed regularly. After 500 hours, the engine needs to be routinely maintained to change the oil and filter elements of engine, diesel, oil and water. Volvo excavator hydraulic filter elements are used in various oil systems to filter out solid impurities mixed in externally or internally generated during system operation. They are mainly installed on the oil suction road, pressure oil road, oil return line, and bypass in the system. Separate filter system superior. Diesel 500, oil 500 (the boss can consider 400 for caring), air filter 2000 (if the dust is more than 1000, change it), hydraulic oil 2000, and air-conditioning filter element should be changed once a year. There is no certain time for this. Generally speaking, when the oil quality fails to meet the requirements, the filter element must be replaced. The time is determined by itself. Because the working environment and workload are different, the service life of the filter element is also different. The quality of the filter element is different, and the time of use is also different. When replacing the filter element, it is recommended to find Guan Wannuo Filter Factory. The company specializes in the production of hydraulic oil filter elements for excavators of various brands, and the product quality is OK.
Volvo excavator hydraulic filter element filter material
The material of Volvo excavator hydraulic filter element is paper filter element, chemical fiber filter element: glass fiber metal fiber sintered felt polypropylene fiber. Polyester fiber mesh filter element: Volvo excavator hydraulic filter element mainly includes stainless steel powder sintered filter element, stainless steel composite mesh sintered filter element, stainless steel woven mesh, etc., as well as PTFE polytetrafluoroethylene folded filter element, but PTFE needs to have internal It is lined with stainless steel frame material to cope with the deformation of the filter element frame caused by high temperature.
