Problems solved by technology

However, the amount should not be too large, because when the amount is too large, there will be a square relationship resistance, which has a great impact on the speed, so special attention should be paid to the amount
Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering, but now many The viscosity of lubricating oil changes greatly with temperature, and the effect is poor in processing operations with large temperature changes

Abstract

The invention relates to lubricating oil. The lubricating oil consists of phosphate, dialkyl zinc dithiophosphate, succinimide, salicylate, polymethacrylate, an antioxidant alpha-naphthylamine, N,N-bisec-butyl p-phenylenediamine, chlorinated paraffin, a rust remover and a demulsifying agent. The lubricating oil disclosed by the invention is good in using effect in a relatively wide temperature range, applicable to be used as the lubricating oil for a diesel engine, small in viscosity in use, capable of commendably saving energy and reducing oil consumption, and also not too large in viscosity during low-temperature start in order to prevent the problem of difficulty in start.

Description

Technical field [0001] The invention belongs to the field of industrial oils, and specifically relates to a lubricating oil. Background technique [0002] When the engine is running, if some friction parts are not properly lubricated, dry friction will occur. Practice has proved that the heat generated by dry friction in a short period of time is enough to melt the metal, causing damage to the mechanical parts or even jamming (many water or oil leaking cars have troubles such as pulling cylinders and holding axles, the main reason is this). Therefore, the friction parts in the engine must be given good lubrication. When the lubricating oil flows to the friction part, it will adhere to the friction surface to form an oil film to reduce the resistance between the friction parts. The strength and toughness of the oil film are the key to its lubricating effect. However, the dosage should not be too large, because when the dosage is too large, it will produce resistance of the squar...
