BETTCHEM multi-purpose agricultural machinery oil additive helps ensure a bountiful autumn harvest.

Right now, the nationwide harvest of autumn grains has entered its peak period.

As agricultural modernization continues to deepen,

More new agricultural machines are being deployed to the front lines of the autumn harvest.

The transmission system, as the core component of agricultural machinery,

As agricultural machinery transmission systems continue to be upgraded,

The requirements for lubricating oils regarding their load-carrying capacity, oxidation stability, and friction performance are becoming increasingly stringent.

Harsh operating conditions—performance first.

The shift in agricultural production methods has led to a sharp increase in demand for machinery and equipment.

Modern agricultural machinery not only needs to operate stably under heavy loads for extended periods, but also...

We also need to address complex challenges posed by diverse climates and geological conditions.

Especially now, during the busy autumn harvest season.

The efficient operation of agricultural machinery directly affects the harvest of crops.

Whether it's a tractor, a combine harvester, or other agricultural machinery equipment

All will face extreme operating conditions such as frequent startups, prolonged operation, and high temperature and high pressure.

Given the relatively harsh operating conditions faced by agricultural machinery, the following key performance aspects require particular attention:

I. Load-bearing capacity

As non-road vehicles, agricultural machinery’s transmission systems are subjected to numerous low-speed, heavy-load operating conditions as well as impact loads. Therefore, the lubricating oil must exhibit excellent load-carrying performance, rapidly forming a boundary adsorption film or a chemical reaction film under low-speed, heavy-load or impact-loading conditions in gear mechanisms, thereby preventing gear surface wear, scoring, and galling.

• Rust resistance performance

Liquid-phase corrosion reflects the oil's tendency to corrode metal components under conditions where water is present. Corrosion resistance Since agricultural machinery inevitably comes into contact with moisture during field operations, the lubricants must exhibit excellent liquid-phase rust-prevention performance. The moisture in the transmission systems of agricultural machinery primarily originates from: “Freshwater”—for this reason, liquid-phase corrosion test conditions are generally set to distilled water. A Law).

• Friction performance

Friction performance is a key characteristic of lubricants used in agricultural machinery transmission systems, directly affecting gear-shifting feel and wet-brake performance. The end-point dynamic coefficient of friction of the oil is measured under various conditions of temperature, pressure, and rotational speed. mu _{And E} ) and the coefficient of kinetic friction at the midpoint ( mu _M ) and mu _{And E} With mu _M the ratio ( E/M ) Determine the friction performance of the oil.

• Oxidation stability / Low sludge tendency

The oxidative stability of an oil reflects its resistance to aging. CEC L-48 This method is widely used to evaluate the oxidation stability of transmission oils, taking into account the operating temperatures and oil-change intervals of agricultural machinery. CEC L-48-00 ( B ) The method will then define the experimental conditions. 150 °C, 192h and with 100 The rate of change in kinematic viscosity and the increase in acid value are used to evaluate the oxidative stability of lubricating oils.

During oxidation, lubricating oils may produce sludge and gum-like substances. If these deposits adhere to the surfaces of components, they can clog lubrication passages, increase friction, and impair heat dissipation. Therefore, a low tendency to form sludge is also an essential performance characteristic for lubricants used in agricultural machinery transmission systems.

Of course, the industry standards for lubricants used in agricultural machinery transmission systems are already highly comprehensive, and all the technical requirements specified in these standards are equally important and essential. For lubricant companies, a high-performance, multi-purpose, and highly stable composite additive for agricultural machinery can help enterprises better reduce costs and improve efficiency.

BETTCHEM BT5050 The highlight lies in... Excellent gear wear protection, rust prevention performance, corrosion control, and oxidation stability. / It has a low tendency to form sludge. At the same time, it can be used to formulate lubricants for transmission systems, hydraulic gears, and brake systems—all in one common lubrication system.
