(1) pollution of new oil. It is generally believed that the newly purchased hydraulic oil is clean, in fact, this understanding is wrong. Most users buy hydraulic oil, in the transport process due to the container itself is not clean and the process of transport is not strictly sealed and other issues, it is likely to cause pollution. The newly purchased hydraulic oil for sample testing found that its pollution is greater than the NAS11 level, far can not meet the hydraulic system on the use of hydraulic oil requirements. (2) external intrusion of pollutants. External intrusion of pollutants mainly in the atmosphere of dust, through the fuel tank holes, hydraulic cylinder shaft seal, refueling, maintenance was opened seals, pumps and motor shaft, etc. into the system. Engineering rig in the field of construction, in the use of special attention to dust. (3) internally generated contaminants. These processes can not be avoided, but the resulting contaminants should be minimized. Assembly and commissioning of special components must be carried out in a clean room (eg, in a clean room), as well as in the clean room, in the process of installation, assembly, commissioning, packaging, storage, transportation and installation. get on. (4) the hydraulic system of pollutants. Hydraulic system in the course of work continue to produce metal and sealing material wear abrasive particles, filter material peeling off the particles or fibers, peeling paint fragments, oil metamorphism after the chemical reaction to the metal corrosion and the particles, rust and so on Belongs to this class.
