Oil hazards Keywords: oil | lubricants | machinery and equipment machinery and equipment in the work, lubricating oil due to long-term contact with the metal by the ambient air temperature, pressure, electric field, light and other factors, an increase in oil gradually foreign substances, which results in the oil in water will, at the end of the dust, sand, metal shavings, and the long-term use gradually oxidized so that a change in chemical composition, resulting in deterioration and harmful impurities. Generally have the following categories: 1, defaced by a foreign substance use lubricant in the system susceptible to a variety of mechanical impurities during dirty. Wherein the end metal, dust, sand, fiber material and the like. This is due to the friction parts worn down metal powder fall into the oil, or because of lax systems and mechanical enclosure and make sand dust intrusion oil. Another phenomenon is a liquid diluted with contaminated or other work, such as a diesel engine, since part of the combustion of the fuel oil did not flow completely to the lubrication system, the lubricating oil is gradually diluted. 2, when the dirty water in the lubricating oil in machinery and equipment, often water infiltration, which is due to a variety of mechanical equipment lubrication system, hydraulic transmission, or water-cooling unit tight enough so that water flows into the oil, in addition, the air Water can be absorbed, because the oil has water absorption, water absorption is determined by the size of the ambient temperature. Such as transformer oil transformer dissolved moisture and temperature have a great relationship. 3, the thermal decomposition of a wide variety of oils, and high when it is part of the mechanical contact device, such as an engine fuel in the combustion zone, when in direct contact with red-hot metal and hardened, and the high pressure oil at the beginning of the arc direct contact, will suffer from a great local overheating phenomenon direct partial combustion, and can heat the oil to a relatively high temperature, then the oil will be thermally decomposed (cracking), and the results will be generated gum Coke, which is called coke. 4, the oxidation of the lubricant during use, mainly due to chemical changes in the role of oxygen in the air, the oil in the working length of time with the temperature increase, the contact area with the air to increase the contact pressure increases and other factors, role and deepened, with the result that the oil generated some harmful substances, such as acids, resin and asphaltene and so on. Due to increasing oil oxidation, dark discoloration of the oil, the viscosity increases, acid quality increases, the oil appears deep mixed slag, so increasing impurity content. 5, heavy metals (ash) sources of heavy metals has two aspects, one that comes with the new base oil and additives in the heavy metal content of heavy metals, and second metal equipment wear off, the presence of heavy metals in the ash content of the excessive use.
