The difference between low-temperature anti-wear hydraulic oil and ordinary hydraulic oil. How often should hydraulic oil be changed? Excavator 3000 hours

Description :

　　Low temperature anti-wear hydraulic oil is refined by isomerization dewaxing synthesis of base oil and carefully formulated with various high-performance additives to become a long-life low pour point anti-wear hydraulic oil. Reduce equipment maintenance costs: Contains extreme pressure anti-wear additives, which can effectively control gear and bearing wear even under heavy load conditions for a long time, and provide a long service life for hydraulic pumps, reducing maintenance frequency. Excellent low-temperature performance: can be used in harsh low-temperature environments Hydraulic system pressure stability: excellent anti foaming and air release properties, better meeting the circulation requirements of lubricating oil, ensuring accurate power transmission, reducing microseismicity at least, thereby avoiding the possibility of surface wear due to lubrication film defects.

　　Hydraulic oil, also known as anti-wear hydraulic oil, is usually referred to as hydraulic oil for simplicity. Hydraulic oil is a general term, which is divided into ordinary anti-wear hydraulic oil, high-pressure anti-wear hydraulic oil, high-pressure ash free anti-wear hydraulic oil, low-temperature anti-wear hydraulic oil, low-temperature ash free hydraulic oil, low-temperature hydraulic oil, low-temperature ash free hydraulic oil, aviation hydraulic oil, jack hydraulic oil, etc

　　Low temperature hydraulic oil is divided into ordinary low-temperature hydraulic oil and cold region anti-wear low-temperature hydraulic oil according to its low-temperature performance and anti-wear performance. It can be used in the northern cold season and can also be used throughout the country.

　　The correct usage method of anti-wear hydraulic oil:

　　Firstly, it is necessary to choose the right oil: the appropriate viscosity grade must be selected based on the design parameters, operating conditions, ambient temperature, etc. of the hydraulic system. Excessive viscosity can lead to increased pressure drop and power loss in the operating system, while excessive viscosity can make it difficult to start in cold seasons. The viscosity is too low, the internal leakage of the pump increases, and the volumetric efficiency decreases. If the viscosity is too low, the system pressure will decrease, the oil temperature will increase, and wear will increase, which can easily cause system control failure. It is necessary to have good lubricity to ensure that important components of the system are not worn out and to reduce failures (especially with more prominent requirements for anti-wear hydraulic oil). It has good adaptability to non-metallic materials such as elastic seals and coatings, and will not cause metal corrosion, coating dissolution, or excessive expansion of rubber. The product needs to have good foam resistance and air release, good filterability and a certain degree of cleanliness. Considering economy, choosing the right one doesn't necessarily have to be expensive.
