Leak Detection(泄漏检查)
1. CLOSE the valve 430 at the last but one Hydraulic ylinder Unit.
2. OPEN the valve 431 at the last HCU to decrease the pressure in the space
between the inner and outer pipe.
3. CLOSE the valve 431 at the last HCU again.
4. Check the pressure increase in the space between at pos.435,at the last HCU
56 If the pressure increases to system pressure level,the leakage has been found.
When the leakage has been eliminated,bring all the valves to their normal position.
1. 关闭阀430在最后一个液压缸单元。
2. 打开最后一个HCU处的阀门431,降低空间压力
内外管之间。
3.再次关闭最后一个HCU的阀门431。
4. 检查最后一个HCU位置435处的间隙压力增加情况
如果压力上升到系统压力水平,则发现有泄漏。
当泄漏消除后,将所有阀门恢复到正常状态的位置。
