液压系统使用 46#耐磨液压油。加油或补充液压油时，必须使用10μm

The hydraulic system uses 46# wear-resistant hydraulic oil. <br>When refueling or replenishing hydraulic oil, the hydraulic oil must be filtered by an oil filter device with a filter accuracy of 10μm before adding it to the oil tank. <br>The hydraulic oil should be replaced with new oil after two years of use. <br>Before adding new oil, the manhole should be opened, and the oil tank should be cleaned out <br>of the high-pressure double- cylinder oil filter of the hydraulic system. The return oil filter is equipped with a blockage alarm switch. When the oil filter is blocked and alarms, the filter element should be replaced in time, otherwise It will cause the system to malfunction due to oil contamination. <br>After the oil filter has been used for one year, the filter element should be replaced regardless of whether it is clogged. <br>The accumulator configured in the hydraulic system should be checked every six months to see if its charging pressure is at the specified value. <br>During the inspection, the hydraulic oil in the accumulator should be emptied and measured with a special charging valve when the accumulator is not filled with liquid. <br>If the nitrogen pressure in the airbag is insufficient, the accumulator inflator should be used to inflate to the specified pressure value.

The hydraulic system uses 46# wear-resistant hydraulic oil. When refueling or replenishing hydraulic oil, the hydraulic oil must be filtered by an oil filter with a filtering accuracy of 10μm before being added to the oil tank. After using hydraulic oil for two years, replace it with new oil. Before adding new oil, open the manhole and clean up the oil tank. The high-pressure double-cylinder oil filter and oil return filter of the hydraulic system are all equipped with blockage alarm switches. When the oil filter is blocked for alarm, the filter element should be replaced in time, otherwise the system will fail due to oil pollution. After using the oil filter for one year, whether it is blocked or not, the filter element should be replaced. The accumulator equipped with hydraulic system should be checked once every six months to see if its inflation pressure is the specified value. When checking, the hydraulic oil in the accumulator should be emptied, and measured with a special charging valve when the accumulator is not filled with liquid. If the nitrogen pressure in the airbag is insufficient, the accumulator inflator should be used to charge to the specified pressure value.
