Checking and Replacement Techniques for Hydraulic Oil in 800-Ton Four-Column Hydraulic Press - Compiled by Hydraulic Press Manufacturer
If the oil temperature of the 800-ton four-column hydraulic press is excessively high, check whether the set value of the pressure control valve is too high. If it is, reduce the working pressure of the machine.
After the hydraulic press has naturally cooled down, open the oil drain plug and take an oil sample.
Check the viscosity index of the oil. If the viscosity is too low, it will affect the pressure indicators of the hydraulic press.
If the oil is visibly cloudy or contaminated with water, it is recommended to replace it as soon as possible.
When replacing the hydraulic oil, make sure to drain all the oil from the entire hydraulic system of the 800-ton four-column hydraulic press, including the hydraulic tank. Replace all the oil, ensuring that each oil change does not fall below 100 kg.
In the case of heating due to leakage at the connection between the hydraulic pump and the hydraulic press, tighten all connections and enhance sealing.
If the hydraulic press has a small oil tank capacity and poor heat dissipation conditions, increase the oil tank capacity and install cooling equipment.
