What are the factors that affect the efficiency of coal washing equipment? And for this device, the indispensable accessory is its gear, and what are the factors that affect the lubrication of this accessory? Next, I will explain it to everyone, hoping it will be helpful to you.

　　1. Temperature

　　When the temperature drops, the smooth oil will thicken. When the temperature rises, it will become thinner. Therefore, low viscosity smooth oil is required under low temperature conditions, while heavy oil is required under high temperature conditions to prevent dry conflicts between metals.

　　2. Load

　　High viscosity oil is more resistant to heavy loads and prevents collisions between metals than thin oil. Therefore, light loads require low viscosity smooth oil, while high loads require high viscosity smooth oil.

　　3. Speed

　　The faster the sliding and rotating speed, the less time it takes to squeeze the smoothing agent between the gears. At the same time, smooth oil is more prone to clumping and thickening during high-speed operation. Therefore, use high viscosity and heavy oil at low speeds, low viscosity oil and thin oil at high speeds.

　　4. Gear category

　　When using straight teeth, helical teeth, herringbone teeth, and bevel gear pairs, sliding and rotation can cause useful oil films to slow down the direct contact between the meshing teeth. The goal of relative sliding operation is not conducive to maintaining the oil film on non equal axis transmission devices such as turbine rods and hyperbolic gears in coal washing machines. On this transmission device, there is often a significant occurrence of smooth boundaries. Therefore, heavy oil is still required on turbine worm gear devices and large eccentricity hyperbolic gear transmission devices. When these transmission devices are subjected to heavy loads and high pressures, it is necessary to choose smooth oils with high viscosity, smoothness, smoothness, or even extreme pressure enhancers that possess the characteristics of high-strength oil films.

　　5. Instantaneous pressure

　　The rhythmic force emitted by the engine requires a smooth boundary compared to heavy oil to prevent sudden splitting of the oil film, as only a small amount of smooth oil can be left behind. In this situation, a smoothing oil containing an extreme pressure booster is required.
