Description

Technical field

[0001] The invention relates to a hydraulic oil filter device, in particular to an oil filter device using variable structure filtering, magnetization, adsorption and rotating magnetic field, 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 solid particle...

Embodiment Construction

[0040] Please refer to the attached figure 1 To attach Figure 17 As shown, the present invention is an oil filtering device adopting variable structure filtering, magnetization, adsorption and rotating magnetic field. Runner 17, filter element 18, outer tub 19 and end cap 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 housing 89 , an output tube 811 , an elastic thin wall 87 , a plug-in H-type filter 812 and a plug-in series H-type filter 813 .

[0042] Wherein, the input pipe 81 is connected to one end of the casing 89 , which is connected to a hydraulic oil inlet 1 ; the...
