两台强夯机做相同工况的强夯作业,起升时间几乎相差一倍。根据现场施工情况和强夯机的使用说明书,通过计算,确定所需起升时间长的强夯机为故障机,故障现象为起升速度慢。遵循先易后难,先观察后试验的原则对故障原因进行排查,对该型强夯机的液压系统进行分析,经过观察、检测及拆检,发现故障所在。通过更换梭阀上的破损O形密封圈,重装后试机,起升速度恢复正常,故障排除。
Two strong tamping machine to do the same working conditions of dynamic compaction, lifting time almost doubled. According to the site construction and the use of strong tamping machine manual, through calculation, to determine the required long tamping machine for the failure of the machine, the phenomenon of failure to lift slowly. Follow the first easy after the first hard to observe the principle of the test to troubleshoot the cause of the failure, the dynamic system of the tamping machine analysis, after observation, inspection and disassembly, and found the fault lies. Replace the shuttle valve on the damaged O-ring, reloading the test machine, hoisting speed back to normal, troubleshooting.
