Defu supply lubricating oil to cool various parts of the country dedicated removable cooling plate heat exchangers

Lubricant cooling down special removable plate heat exchangers Tel: 18305346630 QQ: 848071990 Taobao shop: Populus Tianshan shop link: http; // defuhuanreqi.taobao.com the total amount of petroleum oil in an amount of more than 90%, so lubrication oil usually refers to petroleum oil. Mainly used to reduce friction between the moving parts of the surface, while the equipment has a cooling, sealing, corrosion, rust, insulation, power transmission, clean impurities and so on. Mainly in the lubricating oil fraction and a residual fraction from the crude distillation unit for raw materials. The main properties of the lubricating oil viscosity, oxidation stability and lubricity, they are closely related to the lubricating oil composition of the fractions. Viscosity is an important reflection of the quality of lubricating liquidity indicators. Different conditions have different viscosity requirements. Heavy-duty and low-speed machinery to use high viscosity oil. Represents oil oxidation stability in the environment of use, the temperature, oxygen in the air as well as antioxidant capacity of the metal catalytic performance. After the oxidation of oil, according to the conditions of use will generate small asphaltenes-like carbon-based material, it was viscous paint or paint-like substance, aqueous or viscous material, thereby reducing its performance or loss. Lubrication indicate wear properties of lubricating oil. The lubricating oil additive is added to the lubricant in the concept of one or more compounds to the lubricant obtain some new features or to improve some characteristics of conventional lubricants. Additives according to the functions are mainly antioxidant and metal deactivators, extreme pressure anti-wear agents, friction modifiers (also known as an oily agent), detergent dispersants, foam inhibitors, rust inhibitors, oxidation preservatives, flow point improving agent, viscosity index improver, anti-type emulsions and the like. Market in the sale of the above additives are generally single additive composite products, the proportion of the difference is the different components of a single additive and compound additives inside several single additive is different. Lubricate the engine is running, if some friction parts are not properly lubricated, it will produce dry friction. Practice has proved that the dry friction in a short time to produce enough heat to melt the metal, resulting in mechanical damage or seizure (many leaks or spills occur pull-cylinder car, axle failure, the main reason lies in this). It is necessary to give good lubrication of the friction in the engine area. When the oil to a friction parts, it will adhere to form a film on the friction surface, reducing mechanical friction between the resistance and the film strength and toughness is the key to play its lubricating properties. But do not use too large, because it will produce resistance when the square is too large, a great impact on the speed, so pay special attention on dosage. Cooling the fuel heat in the engine combustion produces only a small portion for the power output and the driving friction on consumption and auxiliary bodies; most of the remaining gas to the atmosphere with heat in addition to Chinese and foreign, will be the engine of the cooling medium take part. The engine must be drained of excess body heat, otherwise the engine will burn due to high temperature. In this regard by the engine cooling system to complete, after the lubricating oil on the other hand by absorbing heat from the cylinder, piston, crankshaft surface to distribute the oil pan. Washing the engine, it will produce a lot of dirt. If inhaled air to bring the sand, coke dust, combustion gas mixture formed after oxidation of lubricating jelly, mechanical friction between the metal shavings and so on. The dirt will be deposited on the surface of mechanical friction, if not cleaned off, it will increase the mechanical wear and tear. In addition, the large number of glial make piston rings jamming, causing the engine can not operate normally. Therefore, we must promptly clean up the dirt, the cleaning process by lubricating oil circulating in the body to complete.

However, these gaps can cause cylinder seal is not good, the result is to reduce the leakage chamber cylinder pressure and engine power output. Lubricating film formed in these gaps, to ensure the tightness of the cylinder, and the cylinder pressure to maintain the output power of the engine, and to prevent exhaust gases downwardly into the crankcase. Antirust when the engine is running or storage, air, oil, fuel moisture and acid gases produced by combustion, will cause corrosion and rusting parts, thereby increasing the damage to the friction surfaces. Mechanical lubricant film formed on the surface, to avoid direct mechanical contact with water and acid gases and prevent corrosion and rust. Elimination of the impact load in the compression stroke end, the mixture starts to burn, a sharp rise in the cylinder pressure. In this case, the bearing clearance in oil will ease pistons, piston pins, connecting rods, crankshaft and other parts are subjected to impact load, the engine is smooth, and to prevent direct contact with the metal, reducing wear and tear.
