The role of hydraulic filter

The method of collecting pollutants in the fluid is a variety of forms. The appliances that capture pollutants made by filtering materials are called filters. The magnetic pollutant is called a magnetic filter with a magnetic material. There are also electrostatic filters, separation filters, etc. In the hydraulic system, all those who collect polluting particles in the fluid are called hydraulic filters. In addition to the most widely used hydraulic filter, in addition to the method of using porous materials or winding fine gaps to intercept pollutants, there are also magnetic filters and electrostatic filters for hydraulic systems.
After the above impurities are mixed with hydraulic oil, with the circulating effect of hydraulic oil, it will have a destructive effect everywhere, which seriously affects the normal operation of the hydraulic system, such as a small gap between the relative motion components in the hydraulic component (with μM) and the festival. The flowing holes and gaps are stuck or blocked; the oil membrane between the relative motion components is destroyed, the surface of the gap is scratched, the internal leakage is increased, the efficiency is reduced, the heating is increased, the chemical effects of the oil are exacerbated, and the oil deteriorates. According to production statistics, more than 75%of the failure in the hydraulic system is caused by impurities mixed with impurities in hydraulic oil. Therefore, it is important to maintain the cleaning of oil to prevent oil from pollution.
General hydraulic filter is mainly composed of filter element (or filter) and case (or skeleton). The countless gaps or small holes on the filter element constitute the circulation area of oil. Therefore, when the impurities in the mixed oil are greater than these tiny gaps or small holes, they are blocked and filtered out of the oil. Because different hydraulic systems have different requirements, it is impossible to completely filter the impurities mixed in the oil, and sometimes it is not necessary to demand.
