Volvo excavator hydraulic oil filter cleaning steps

How to clean the hydraulic oil filter element of Volvo excavator and how long is the cleaning cycle? The cleaning cycle of Volvo excavator filter element is generally 3 months. If there is a differential pressure alarm system, the filter element will be replaced according to the differential pressure. This article will introduce you to cleaning methods.

Volvo excavator filter cleaning steps

1. Drain the original hydraulic oil before cleaning, check the oil return filter element, oil absorption filter element, and pilot filter element to see if there are iron filings, copper filings or other impurities. .

2. When cleaning hydraulic oil, 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.

3. Identify the hydraulic oil label. Do not mix hydraulic oils with different labels and brands, which may react and deteriorate to produce floccules. It is recommended to use the oil specified for this excavator.

4. The oil suction filter element must be installed before refueling. The nozzle covered by the oil suction filter element directly leads to the main pump. The entry of impurities will accelerate the wear of the main pump, and the pump will be beaten.

5. Refuel to the standard position, there is generally an oil level gauge on the hydraulic oil tank, see the level gauge. Pay attention to the parking method, generally all cylinders are fully retracted, that is, the forearm and bucket are fully extended and landed.

6. After cleaning the Volvo filter element, pay attention to the main pump to exhaust air, otherwise the whole car will not move temporarily, the main pump will make abnormal noise (air sonic boom), and the cavitation will damage the main pump. The air exhaust method is to directly loosen the pipe joint on the top of the main pump and fill it up directly.

Cleaning precautions

Volvo excavator filter

1) Rinse the tank with an easy-drying cleaning solvent, then use filtered air to remove solvent residue.

2) Precautions for cleaning all pipelines of Volvo filter system. In some cases, the pipelines and joints need to be impregnated.

3) Install an oil filter in the pipeline to protect the oil supply pipeline and pressure pipeline of the valve.

4) Install a flushing plate on the collector to replace the precision valve, such as electro-hydraulic servo valve, etc.

5) Check that all pipelines are properly sized and connected correctly.

Volvo hydraulic filter main filter material

1. Commonly used filter media are surface type and depth type: Surface type: the shape of the holes is regular, and the size is basically the same: the filtration only occurs on the surface of the filter media, the pollutants are intercepted upstream of the filter media, and the pollutant holding capacity is small, and the commonly used materials are metal Depth type such as silk woven mesh, metal microporous plate, filter membrane, etc.: composed of fibers or particles, the micropores are irregular in shape, uneven in size, intercept and absorb pollutants, and have a large pollutant holding capacity. The commonly used materials are filter paper, non-woven Cloth, metal fiber sintered adhesive, powder sintered adhesive, etc.

2. In Volvo hydraulic system, the commonly used filter materials include inorganic fiber composite filter paper, plant fiber filter paper, and metal wire woven mesh, among which inorganic fiber composite filter paper has become the main choice.

3. Volvo hydraulic filter is a composite filter paper with glass fiber as the main raw material. It is processed by wet method, and the filtration precision can be controlled manually. It has the advantages of plant fiber and chemical fiber and is widely used.

With the development of filter material manufacturing and the higher requirements of the hydraulic system, the gradually dense filter material has become the development trend and will definitely play a leading role. The gradually densified filter material can be directly synthesized by the filter material manufacturer, or can be used in combination with different precision filter papers.
