Special oil for construction machinery, also known as construction machinery lubricating oil, refers to the special lubricating oil specially used for large-scale mechanical equipment such as large-scale excavation machinery, loading machinery, hoisting machinery, bulldozing and road building machinery. What kind of oil is the special oil for construction machinery? Special oil for construction machinery mainly includes four categories, including diesel supercharged engine oil for construction machinery, anti-wear hydraulic oil for construction machinery, heavy-duty gear oil and hydraulic transmission oil, with more than ten varieties.
Special oil for construction machinery
Special oil for construction machinery mainly includes oil for production process, oil for mechanical equipment filling and after-sales oil. The oil used in the production process is mainly the oil used in the metal processing process. The filling and after-sales oil of construction machinery mainly includes engine oil, hydraulic oil, gear oil and hydraulic transmission oil. Engine oil and construction machinery are often in high-speed and high-load working conditions. The power equipment has the characteristics of complex working conditions, high power, thermal load and high sulfur content of fuel. Engine oil needs to have better and lasting high-temperature purification and dispersion, stronger acid neutralization ability, better corrosion resistance, high fuel economy and compatibility of aftertreatment system.
Lubricating oil is generally the product of fractionated oil, and it is also extracted from animal and vegetable oil, including "lubricating grease". It is generally a non-volatile oil lubricant. It is a liquid lubricant used in various types of machinery to reduce friction and protect machinery and processing parts. It is mainly used for lubrication, cooling, rust prevention, cleaning, sealing and buffering.
The quality grade of special oil for construction machinery shall be determined according to the recommendations of the internal combustion engine manufacturer, the mechanical load and thermal load of the diesel engine, the severity of working conditions and other factors. High viscosity oil shall be selected for construction machinery with large tonnage, heavy load and continuous high-speed operation to ensure sufficient oil film strength at high temperature; Small mechanical equipment with small load and moderate working condition can use diesel engine oil with low viscosity.
Special oil for construction machinery is widely used. Special oil for construction machinery is specially used for construction machinery. Neither construction machinery nor automobiles should be mixed. It will be better if matched.
