However, the long-term non-use of the equipment can cause the phenomena of emulsification, oxidation or oil deterioration of the hydraulic oil in the pipeline. If the devices are directly opened again, the pollution of the hydraulic valve is caused, and particularly, in the case of a proportional valve and a servo valve, the problems of valve core blockage, nozzle hole blockage of the servo valve and the like are caused. Therefore, it is common to take the form of a direct start-up for equipment that is not soon shut down, but the direct start-up can cause servo valve failure if the equipment is shut down for too long.
