Abstract:

This work aims at characterizing the behavior of the hydraulic filters used to reduce the polluting particles contained in the hydraulic systems working to high pressure, live with aim at the pollution of the fluid employed. By analyzing the cause of the hydraulic installations breakdowns, one notes that they are caused in most of the cases by the hydraulic fluid which exceeds a threshold of pollution following an insufficient filtration. An analysis of pollution was carried out on the level of two filters on a hydraulic system (one on the discharge pipe whose pressure is about 250 bar with an filtering element of mesh x=15 ?m and a second on the return line towards the tank subjected to a pressure P = 10 bar, having meshes dimension of x = 25 ?m).This study is based on the analysis of the effectiveness, the rate of separation as well as the degree of retention of these two hydraulic filters (pressure filter and that of return) of a hydraulic system on the level of the iron and steel hot rolling mill in ARECLOR MITTAL complex in Algeria.In addition, our study is based on the method of the oils analysis by the electronic counting of the particles according to the standards (NAS 1638), and detect the relation which exists between the number of the particles selected and the differential pressure, as well as the frequency of each filter filling
