泥浆泵的拉杆与缸套是一种易损另件，尤其是使用泥浆的就更为显著，所以使用中更换频繁。从前我队采用的恢复办法，是既费氧气（或电焊条）又费工时，实不经济，尤其是处在深山的野外勘探队，氧气来源困难，因此，恢复工作就更有问题了。 Mud pump rod and cylinder liner is a fragile pieces of other, especially the use of mud is even more significant, so the use of frequent replacement. In the past, our team resorted to recovery measures that cost both oxygen (or welding electrodes) and labor-intensive labor. It is not economical, especially in field exploration teams in the deep mountains, where oxygen sources are difficult to come by. Therefore, recovery work is even more problematic.
