Description

Technical field

[0001] The invention relates to a hydraulic oil filter, in particular to an oil filter using self-adaptive filtering, electrification and rotating magnetic field in full frequency band working conditions, and belongs to the technical field of hydraulic equipment.

Background technique

[0002] Statistics at home and abroad show that about 70% to 85% of hydraulic system failures are caused by oil pollution. Solid particles are the most common and harmful pollutants in oil pollution. Hydraulic system failures caused by solid particle pollutants account for 70% of total pollution failures. Metal debris accounts for 20% to 70% of the particle pollutants in hydraulic system oil. Taking effective measures to filter out the solid particle pollutants in the oil is the key to the pollution control of the hydraulic system, and it is also a reliable guarantee for the safe operation of the system.

[0003] Filters are key components of hydraulic systems to remove s...

Embodiment Construction

[0040] Please refer to the attached figure 1 To attach Figure 18 As shown, the present invention is an oil filter with adaptive filtering, electrification and rotating magnetic field in full frequency range, which consists of a base plate 6, a filter 8, a U-shaped particle separation module 3, an oil return cylinder 7, and an inner cylinder 15. The spiral flow channel 17, the filter element 18, the outer barrel 19 and the end cover 25 are composed of several parts. Wherein, the filter 8 , the U-shaped particulate separation module 2 , the oil return cylinder 7 , and the outer barrel 19 are placed on the bottom plate 6 in sequence.

[0041] The filter 8 is used to input the hydraulic oil, and can attenuate the pulsating pressure in the high, medium and low frequency bands in the hydraulic system, and suppress the flow fluctuation. The filter 8 is composed of an input tube 81 , a casing 88 , an output tube 89 , an elastic thin wall 87 , an H-type filter 812 and a series H-typ...
