The requirement of installing the long arm of excavator and the solution to the problem of deviation

　　行走跑偏故障：

　　Travel Deviation fault:

　　当华体会国际 出现行走跑偏故障时应当对挖掘机组合阀进行检查。拆卸其限压阀上的2根油管，用堵头堵住出油口，启动发动机，拉动有堵头组合阀的行走操纵手柄华体会国际 ，检测油压正常;再拆卸另一侧行走组合阀上的2根油管，再次启动发动机，观察其限压阀的2个油孔是否存在油液流出，若无此现象，则排除组合阀故障问题。这时，我们应当对中间回转接头进行检查。

　　When the long arm excavator has a travel deviation fault, the combination valve of the excavator should be checked first. Remove the two oil pipes on the pressure limiting valve, plug the oil outlet, start the engine, pull the travel control handle with the plug combination valve and the long arm excavator, and check whether the oil pressure is normal; Remove the two oil pipes on the traveling combination valve on the other side, start the engine again, and observe whether there is oil flow out of the two oil holes of the pressure limiting valve. If there is no such phenomenon, eliminate the failure of the combination valve. At this time, we should check the intermediate swivel.

　　由于中间回转接头处油道众多，油道间易发生串通，因此我们可先将行走马达油管拆卸2个，随后将其中1个马达油管。此动作操作完毕后，再次启动发动机，拉动堵死油管马达的换向阀，观察其油液压力是否过低且是否存在液压马达的油孔油液流出，若存在则视为回转接头的油道密封问题，须将其更换后，故障方可解除。

　　Since there are many oil channels at the middle swivel, the oil channels are easy to cross-talk, so we can remove two oil pipes of the traveling motor first, and then one of them is motor oil pipe. After the operation is completed, start the engine again, pull the reversing valve that blocks the oil tube motor, observe whether the oil pressure is too low and whether there is oil flow out of the oil hole of the hydraulic motor. If there is any, it is regarded as the oil channel sealing problem of the rotary joint, and the fault can be removed only after it is replaced.
