What is the role of the hydraulic oil used in the hose crimping machine Hydraulic oil is the blood of the hose crimping machine equipment, which has the effect of transferring and transforming energy. The accuracy of the selection of hydraulic oil is closely related to the operating power and service life of the equipment. Its functions are mainly manifested in the following points. Today's crimping machine technology Let's analyze it: 1. Appropriate viscosity, viscosity-temperature characteristics Viscosity is the primary consideration when selecting hydraulic oil. Under the same operating pressure, if the viscosity is too high, the movement resistance of hydraulic components will increase, and the pipeline pressure drop and power loss will increase; if the viscosity is too low, the volume of the added oil drum will be lost. The leakage in the assembly increases and the oil film of the sliding parts becomes thinner, so that the support can be lowered, and there is a foggy phenomenon, which overflows from the exhaust port. 2. Lubricity (wear resistance) There are many moving parts in the hydraulic system that need to be lubricated to avoid the wear of the relative moving surface, especially the hydraulic equipment with higher pressure, which requires much higher anti-wear properties of the hydraulic oil. 3. Antioxidant The hydraulic oil is also oxidized during use. The acidic substance generated after the hydraulic oil is oxidized will add corrosiveness to the metal. The generated sludge deposits will block the filter and fine gaps and make the equipment work abnormally. Therefore, it is requested to have Antioxidant. 4. Anti-rust and anti-corrosion When hydraulic oil is in use, it is inevitable to touch moisture and air, as well as acidic substances generated after oxidation, which will affect the corrosion of the metal valve core.

2. Lubricity (wear resistance)

There are many moving parts in the hydraulic system that need to be lubricated to avoid the wear of the relative moving surface, especially the hydraulic equipment with higher pressure, which requires much higher anti-wear properties of the hydraulic oil.

3. Antioxidant

The hydraulic oil is also oxidized during use. The acidic substance generated after the hydraulic oil is oxidized will add corrosiveness to the metal. The generated sludge deposits will block the filter and fine gaps and make the equipment work abnormally. Therefore, it is requested to have Antioxidant.

4. Anti-rust and anti-corrosion

When hydraulic oil is in use, it is inevitable to touch moisture and air, as well as acidic substances generated after oxidation, which will affect the corrosion of the metal valve core.
