What is Lube Oil Used For?
- Lubrication function
Dry friction will happen when the engine is running if some friction elements are not adequately oiled. The heat generated by dry friction in a short time will melt the metal, causing damage to the machine parts and various failures.
Therefore, it’s essential to properly lubricate the engine’s frictional components. Lubricating oil will adhere to the friction surface to form an oil film, reducing the resistance between friction parts.
Note: The strength and toughness of the oil film are the keys to its lubricating effect, and the amount should not be too large.
- Cooling function
Most of the heat generated by the combustion of fuel in the engine is discharged into the atmosphere with the exhaust gas, and part of it is also taken away by the cooling medium in the engine.
Excess heat in the engine must be removed from the body, otherwise the engine will burn out due to overheating. This is accomplished by the engine cooling system on the one hand, and on the other hand is taken to the oil pan to distribute by lubricating oil after absorbing heat from surfaces such as cylinders, pistons, and crankshafts.
- Washing function
During the operation of the engine, many pollutants will be produced. For example, the dust, sand and soil brought in the air, the jelly formed after the oxidation of lubricating oil, the carbon deposit formed after the combustion of the mixed gas, and the metal shavings produced by the friction between the parts, etc.
The circulating flow of lubricating oil in the body can clean these pollutants.
- Anti-rust function
When the engine is running or stored, the atmosphere, lubricating oil, moisture in the fuel, and acid gas generated by combustion will cause corrosion and rust to the parts, thereby increasing the damage of the friction surface.
Lubricating oil can form an oil film on the surface of machine parts, which can avoid direct contact between machine parts and water and acid gas, and prevent corrosion and rust.
- Sealing function
There is a certain gap between the cylinder and the piston, the piston ring and the ring groove, and the valve and the valve seat of the engine. These gaps can cause poor cylinder seals.
Lubricating oil forms an oil film in these gaps, which will ensure the sealing of the cylinder, maintain the cylinder pressure and engine output power, and prevent the exhaust gas from scurrying downward into the crankcase.
- Eliminate shock load function
At the end of the compression stroke, the mixture begins to burn and cylinder pressure rises sharply. At this time, the lubricating oil in the bearing gap will ease the impact load on the piston, piston pin, connecting rod, crankshaft and other parts, prevent direct metal contact, and make the engine work smoothly.
What is Lube Oil Purifier?
Lubricating oil purifier is the equipment used to purify lubricating oil. YUNENG is a well-known manufacturer of lubricating oil purifiers in China. It can provide three kinds of lubricating oil filtering equipment, including JT series coalescence dehydration oil purifier, ZJC series lubricating oil vacuum purifier, and DYJC series turbine oil purification device. These three types of oil purifier units manufactured by YUNENG will be briefly introduced below.
JT Series Coalescing and Dehydration Oil Purifier
JT series coalescing and dehydration oil purifier utilizes coalescing dehydration filter elements and is optimally designed in a certain proportion. It is suitable for the online automatic operation of light oil, turbine oil and lubricating oil system with kinematic viscosity less than 46m㎡/s, especially for the online operation of water leakage units.
It integrates the functions of automatic demulsification, high-efficiency dehydration, precision filtration, etc., and can effectively filter out water and impurities in the oil.
ZJC Series Vacuum Lubricating Oil Purifier
This type of vacuum lubricating oil purifier is based on the principle of vacuum separation, and is suitable for industrial oils such as turbine oil, mechanical oil, hydraulic oil, compressor oil, and refrigerating machine oil with kinematic viscosity less than 320m㎡/s.
It can solve the problems of water ingress, emulsification and particle pollution caused in production, transportation and use.
DYJC Series Online Turbine Oil Purification System
DYJC online turbine oil purification system includes both vacuum system and coalescing dehydration system, which can be used according to actual conditions. It is an online oil purification equipment for water, steam turbine and other lubricating oil units.
It can solve the problem of high water content, serious emulsification, and deep dehydration.
