The role of industrial lubricants
- 2020-03-31-

Industrial lubricating oil is a liquid lubricant used in various types of machinery to reduce conflicts and maintain machinery and processed parts. It mainly has the effects of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Industrial lubricating oil accounts for 85% of all lubricating materials, and there are many types of trademarks. The world's annual consumption is about 38 million tons. Let us introduce the role of industrial lubricants.

1.Lubrication effect

When the engine is operating, if some conflict areas are not properly lubricated, dry conflicts will occur. Practice has proved that the heat generated by dry conflict in a short period of time is sufficient to melt the metal, damage the components and even jam many water or oil leaking cars. The main reason lies in this problem. There is therefore a need for excellent lubrication of conflicting parts in the engine. When the lubricating oil flows to the conflicting area, it will adhere to the conflicting surface to form a layer of oil film, reducing the resistance between the conflicting parts, and the strength and toughness of the oil film is the key to exerting its lubrication effect.

2, scrub effect

During the operation of the engine, a lot of dirt can occur. Such as sand and dust brought in the air, coke formed after the mixed gas is incinerated, gelatinous matter produced after the oxidation of lubricating oil, and metal shavings caused by conflicts between parts. These dirt will adhere to the conflicting surfaces of the parts, and if not cleaned, it will increase the wear of the parts. In addition, a lot of glue will cause the piston ring to stick and stagnate, causing the engine to malfunction. Therefore, it is necessary to sort these dirts in time. This cleaning process is completed by circulating the lubricating oil in the body.

3. Sealing effect

There is a certain gap between the cylinder and the piston of the engine, the piston ring and the ring groove, and the valve and the valve seat, so as to ensure that the movement pairs will not be stuck. However, these gaps can constitute a poor sealing of the cylinder, and the result of air leakage in the incineration chamber is a reduction in cylinder pressure and engine output. The oil film formed by the lubricating oil in these gaps ensures the tightness of the cylinder, maintains the pressure of the cylinder and the output power of the engine, and can prevent exhaust gas from flowing downward into the crankcase.

4. Cooling effect

Only a small part of the heat generated after the fuel is incinerated in the engine is used for power output and conflict resistance consumption and the driving of auxiliary organizations; most of the remaining heat will be carried by the engine's cooling medium in addition to the exhaust gas discharged to the atmosphere. Take part. The excess heat in the engine should be discharged from the body, otherwise the engine will burn out due to excessive temperature. This is accomplished on the one hand by the engine cooling system, on the other hand, the lubricating oil absorbs heat from the surface of the cylinder, piston, crankshaft, etc., and sends it to the oil pan.

5.Anti-rust effect

When the engine is in operation or storage, moisture in the atmosphere, lubricating oil, fuel oil, and acid gases generated by incineration can cause corrosion and rust on the parts, and then increase the damage to the conflict surface. The oil film formed by the lubricating oil on the surface of the machine can avoid direct contact between the machine and water and acid gas, and avoid corrosion and rust.

6.Eliminate impact load

At the end of the compression stroke, the mixture begins to incinerate and the cylinder pressure rises sharply. At this time, the lubricating oil in the bearing gap will alleviate the impact load on the piston, piston pin, connecting rod, crankshaft and other parts, make the engine work smoothly, avoid direct metal contact, and reduce wear.

The above is the effect of industrial lubricating oil, I believe everyone has already understood. Industrial lubricants reduce friction and wear, reduce conflict resistance to save resources, reduce wear to extend the life of machinery, and improve economic efficiency.
