Problems solved by technology

The disadvantages are: the application range of the existing lubricating oil is relatively narrow, and the versatility is poor. Generally, it is only suitable for 1-2 tractor systems. Each tractor needs to be equipped with a variety of corresponding lubricating oils. It is not convenient to use, and it is easy to cause mistakes. oil, causing mechanical failure

Abstract

The invention relates to a tractor five-purpose lubricating oil composition comprising the following components in percentage by weight: 3.5-5.5% of high-temperature detergent, 3.5-5.0% of ashless dispersant, 1.0-1.7% of oxidation and corrosion inhibitor, 0.4-2.5% of oiliness agent, 0.03-0.1% of metal deactivator, 5.0-12.0% of viscosity index improving agent, 0.3-0.8% of pour point depressant, 0.001-0.005% of kilfoam, and the balance of solvent refining base oil or hydrogenated base oil. The lubricating oil composition has easy availability of raw materials, simple production process and highperformance price ratio, and can meet the oil consumption requirements of a whole oil consumption system, namely engine, hydraulic pressure, driving, braking and speed changing of large-medium sized tractors, thereby effectively simplifying oil varieties and avoiding mechanical failures caused by wrong use of oil products; and by using the lubricating oil composition, each lubricating system of the large-medium sized tractors can be kept in a good working state to avoid failures caused by insufficient lubrication, thereby prolonging the service life of the whole machine.

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular to a five-purpose lubricating oil composition for tractors that can meet the requirements of the engine-hydraulic-transmission-braking-speed-change system of large and medium-sized tractors. Background technique [0002] A typical large and medium-sized tractor includes a diesel engine, hydraulic (hydraulic suspension)-transmission (clutch, power output shaft, power conversion, gear transmission)-brake (wet) system, where the engine is a separate oil tank, according to the size and design of the engine power Different, some hydraulic-transmission-brake systems have separate fuel tanks for hydraulic pressure, transmission, transmission, and brake, and some hydraulic-transmission-brake-transmission systems share a single fuel tank. According to the special requirements of different oil systems for lubricating oil, sometimes as many as three types of lubricating oil are used, namely die...
