The Important Role Of Lubricating Oil On Dredgers

Let us introduce the important role of lubricating oil on dredgers:

    1. The volume of the dredging machine and the volume of the fuel tank are small, the amount of lubricating oil installed is also small, and the oil temperature is high during operation, which requires the lubricating oil to have good thermal stability and oxidation resistance.

    2. Because the environment of river water is bad, coal dust, rock dust and water are more, the lubricating oil is inevitably polluted by these impurities, so the dredger oil is required to have better anti-rust, anti-corrosion and anti-emulsification properties; When the lubricating oil is contaminated, its performance will not change too much, that is, it is less sensitive to pollution.

    3. The temperature of the open-air dredger varies greatly in winter and summer. In some areas, the temperature difference between day and night is also large. Therefore, the viscosity of the lubricating oil is required to change with temperature. It is necessary to avoid the viscosity of the oil becoming too low when the temperature is high. The lubricating film cannot be formed, and the lubricating effect should not be achieved, and the viscosity should be too high when the temperature is low, so that starting and running are difficult.

    4. For some dredging machinery and equipment, especially in mines that are prone to fires and explosions, it is required to use a flame-resistant lubricant (anti-flammable liquid), and flammable mineral oil cannot be used.

    5, the lubricant is required to adapt to the seal, so as not to damage the dredger seal.
