Select and Use the Appropriate Machinery Hydraulic Oil

Choosing good and suitable hydraulic oil during use, management and maintenance is very important for the machines. To prevent the hydraulic oil being contaminated , it is necessary to do this. Pollutants biggest hazard is caused by the corrosion of equipment and clogging the filter and the orifice, to accelerate oil aging and corrosion of components, mineral oil and hydraulic oil can work continuously at 50 ~ 65 ℃, the maximum temperature is in the 120 to 140 ℃. Oil temperature rising will accelerate the oxidative deterioration of hydraulic oil and oxidation of acidic substances can cause corrosion of metal components. When the work pressure is high, users should use the high viscosity of the hydraulic oil. To solve the problem of leakage, when the high pressure is to overcome its sticky resistance should be given priority.

The hydraulic pump is one of the most sensitive components of hydraulic oil viscosity and viscosity-temperature performance, and therefore, the system regards hydraulic oil requirement as an important basis for the choice of hydraulic oil, hydraulic components use the compatibility can guarantee a minimum configuration requirements. For choosing the hydraulic oil, uses should pay attention to the types of hydraulic parts , used material seals and paint with hydraulic oil to achieve the design life and to meet the performance requirements. Smaller tank size of oil oxidation has high stability, extreme anti-pressure and anti-wear ability. For many machines, such as hydraulic cone crusher and ball mill etc., it is important to select the high quality oil. Hydraulic oil with high quality standards can speed up the movement of the system implementing agencies, the oil flow rate is also high and hydraulic pressure loss increases. While the leakage relatively reduces, it should choose a lower viscosity oil. Conversely, when the flow rate of the oil increases, the low leakage will have an impact on the working movement speed, then...
