Thus, when the second particle size sensor 131a detects that the particle size of the hydraulic oil in the main pipeline 131 is higher than or equal to the preset particle size, it indicates that the filtering effect is not good, the particle size of the hydraulic oil still does not reach the standard of being discharged into the hydraulic oil station 10, the third electromagnetic valve 132a is closed, the fourth electromagnetic valve 133a is opened, the hydraulic oil flows into the first main pipeline 12a through the second branch pipeline 133 and returns to the oil filtering device 11 for secondary filtering, when the second particle size sensor 131a detects that the particle size of the hydraulic oil in the main pipeline 131 is lower than the preset particle size, it indicates that the filtering effect is good, the third electromagnetic valve 132a is opened, the fourth electromagnetic valve 133a is closed, and the hydraulic oil flows back to the hydraulic oil station 10 through the first branch pipeline 132, so that the oil filtering effect can be ensured, the hydraulic oil with the higher particle size is prevented from flowing back to the hydraulic oil station 10, secondary damage is caused to the hydraulic oil station 10, and the service life of the hydraulic oil station 10 is prolonged.
