Automatic impurity removal system for hydraulic oil

The invention belongs to the technical field of filtration and impurity removal, and discloses an automatic hydraulic oil impurity removal system which comprises an impurity removal device, an oil pump, a driving element, an impurity detection element, an electromagnetic conversion device and a control element. The magnetisable filter screen is used for filtering solid particle impurities in the hydraulic oil and adsorbing metal particle impurities, the oil-water separation device is used for separating water unit impurities in the hydraulic oil, and the control element is in communication connection with the impurity detection element, the driving element and the electromagnetic conversion device. According to the automatic impurity removal system for the hydraulic oil, the control element is suitable for controlling the driving element to drive the oil pump to work so as to pump the hydraulic oil in the oil tank into the impurity removal device after the impurity detection element detects that the impurity
