以液压式上击器为例,分析了震击过程中的能量变化。
The energy variation on a hydraulic upward jar during the jarring process was investigated in the field.
上击器采用液压原理,其震击力可由上提力的大小自由调节,但使用时不允许超过工具限定的最大负荷。
The up jarring section takes use of hydraulic mechanism, the jarring force can be adjusted according to up elevating load but can not exceed the max. load for tool load rated.
