After the hydraulic system is installed, the pipeline, runner, etc. must be cycled before the test. Make system cleanliness meet design requirements.
1) The cleaning fluid should use special cleaning oil with low viscosity or hydraulic oil of the same grade in this system.
2) The cleaning work is mainly based on the main piping system. Before the cleaning, adjust the pressure of the relief valve to 0.3-0.5MPa. The oil discharge circuit of other hydraulic valves should be temporarily cut off at the inlet of the valve, connect the main line to the temporary line, and reverse the reversing valve to a certain position. To make the oil circuit circulate.
3) Temporarily connect a return filter to the return line of the main circuit. Filtering accuracy of the oil filter, 30μm, 20μm, 10μm filter cores are used in different cleaning cycle stages of the general hydraulic system; the servo system uses 20μm, 10μm, 5μm filter elements, and is cleaned in stages. After cleaning, the hydraulic system must meet the purification standards, and systems that do not meet the purification standards are not allowed to operate.
4) The complex hydraulic system can clean each area according to the working area.
5) After cleaning, drain the cleaning oil and confirm that the cleaning oil has been drained before the cleaning is completed.
6) After confirming that the hydraulic system has reached the standard, remove the temporary pipeline, restore the system, and refuel as required.
