Upkeep of Hydraulic Fittings

The quality of a hydraulic fittings system depends not only on the rational design and performance of the merits of system components, but also because of the pollution prevention and treatment system, the system of pollution affects the reliability of hydraulic fittings systems and components work life, according to statistics, the hydraulic fittings system failures at home and abroad about 70 percent is due to pollution caused. Oil pollution among the system are several key harm, you have to have to introduce, respectively. Pollution and wear of hydraulic fittings, oil rise to devices of various pollutants in various forms of wear, solid particles into the kinematic pair gap, on the surface of the cutting parts wear or fatigue wear. High-speed flow of solid particles on the the surface of components caused by erosion impact. Oil in the water and the resultant deterioration of oil oxidation on the corrosive elements. In addition, the system of oil involving air caused by cavitation, resulting in surface erosion and damage components. Plug and the clamping device failure, solid particles to plug the gap and orifice of hydraulic fittings valves, causing valve obstruction and clamping affect work performance, and also result in serious accidents. Accelerate the deterioration of oil properties, oil in water and air for their thermal energy include the main conditions of oil oxidation, oil in the oxidation of metal particles on the oil play a good, solid catalytic role, in addition, oil in water and suspension significantly reduces air bubbles between the film's strength, deputy campaign to lessen lubrication performance. Oil pollution is really a hydraulic fittings system on the system from the side effects of the substance, its oil planet form of another form, can be divided according to their physical form: solid pollutants, liquid pollutants, gaseous pollutants. Pollutants can be divided into hard solid contaminants are: diamond, cutting, silicon sand, dust, wear metals and metal oxides; soft contaminants are: additive, water, condensate, oil and polymer decomposition providers maintenance When the cotton into yarn, fiber. Liquid contaminants you should never meet the system requirements notch oil, water, paint, and halides such as chlorine and its often difficult for folks to get rid of, so replacement for select the line when the hydraulic fittings oil hydraulic fittings oil system standards, avoid some do not necessary failure. Gaseous pollutants a brand new mixed with the air system. These particles are often so small, so can not subside while being suspended in oil, finally pushed into the space among the various valves, hydraulic fittings system on a reliable, these limited control over the achievement gap, importance and accuracy is important. Sources of pollutants: associated with contaminants in the oil system, mainly in the following way: the external intrusion of pollutants: the external intrusion of pollutants is mainly sand or dust your market atmosphere, usually through the tank holes, cylinder seal shaft , pumps and motors shaft penetrated it. Mainly the use of the healthy environment. Internal pollutants: components on the inside machining, assembly, testing, packaging, storage, transportation and setting up other sectors in the remainder contaminants, of course, these processes should not be avoided, but can be reduced to some minimum, one impressive components in the assembly and debugging requires clean room or clean platform setting. Pollutants generated hydraulic fittings system: the system in operation due process component of the products of wear and tear particles, falling down more than a sand castings, pumps, valves and hydraulic fittings while on the metal particles falling down, falling off things corroded pipeline in its oil oxidation and the decomposition in the particles and colloidal matter, even more serious is this system before the pipeline is put into operation without washing and some an associated with impurities.
