Precautions for cleaning the hydraulic system of hydraulic press

The hydraulic system pipeline and oil tank of the hydraulic press are relatively clean, and the cleaning oil can be used with the viscosity of the working fluid. If the system is found to be dirty, the cleaning may be slightly low viscosity oil for cleaning. The accessories of the hot oil system of the hydraulic press hydraulic system are easily detached, and are usually heated to 50-60 ℃. When the cleaning pressure is 0.2-0.4 Mpa, the flow rate of the clean oil is as high as possible to facilitate the removal of dirt.

Normally installed filters are between 50-100 μ In the cleaning circuit of the coarse filter, install a return port of 10-50 at the inlet μ Filter installation. Coarse efficiency filter, gradually switching to fine grid oil filter and gradient filter after flushing for a period of time. The cleaning time is set at eight hours to one day, and every half hour, the hydraulic oil filter of the machine is opened for cleaning, and the fine mesh filter is gradually replaced and washed. Good low viscosity oil is used to extend the cleaning interval, and the heavily polluted hydraulic system of the hydraulic machine is cleaned, reused, and the viscosity of the oil to be cleaned is cleaned using similar oil.

After the cleaning of the hydraulic system of the hydraulic press is completed, add a new hydraulic working oil. After the cleaning oil is removed, immediately add a new hydraulic oil and conduct a short test run to prevent pipeline corrosion and other adverse effects of the hydraulic press. Try to eliminate cleaning oil as much as possible, including pumps, valves, pipelines, and accumulated cleaning oil in the cooler. Loosen the pipeline, blow with compressed air, or add working oil, and remove the cleaning oil.
