Special oil for construction machinery is also called smooth oil for construction machinery. Special smooth oil must be used in the transmission parts of large mechanical equipment such as excavation machinery, loading machinery, hoisting machinery, bulldozing and road building machinery. Smooth oil for construction machinery mainly includes four categories and more than ten types, including diesel booster engine oil for construction machinery, anti-wear hydraulic oil for construction machinery, heavy-duty gear oil and hydraulic transmission oil for construction machinery.
1. Better have more oil than less
We know that a small amount of oil will lead to lack of oil supply, poor smoothness and mechanical accidents. Therefore, when refueling, you should not "prefer to add more" because you are afraid of the lack of fuel. In practice, too much oil will not only increase the power consumption of the crankshaft due to the increase of rotating resistance, but also the oil is easy to produce bubbles, emulsions and spills, resulting in poor smoothness.
2. The engine oil with high viscosity is better for the engine than the engine oil with low viscosity
If the viscosity grade of lubricating oil is too high, the pumping performance of the oil pump will be poor, the flow will be reduced, and its smoothness, washability and heat dissipation will be deteriorated, which is easy to cause semi dry friction of the machine parts, causing problems such as Bush burning and shaft holding.
3. Using high viscosity engine oil can solve the problems of weak work and oil channeling
The external characteristics of the deterioration of the technical condition of the engine are the inability of the engine to work, the consumption of engine oil and the channeling of engine oil, and the lack of basis for "using high viscosity engine oil to solve the above problems". On the contrary, it will increase the starting resistance of the starter, deteriorate the smoothness and aggravate the wear of the parts.
