1985～1986年间,我们改变了原来用强力提拉钻具,切割管材的做法,多次成功地处理了水平钻的一般烧钻和严重烧钻事故,加快了施工速度,同时节约了材料和资金。我们的经验可归纳为: 1.一旦发现烧钻,立即回拔钻具,打开钻机(SGZ—1型)离合器,以避免发生新的机械事故。换向阀推回终止位置,停止钻具回拔,防止机械体移动。 2.分析事故原因,做好处理前的准备工作。 3.将油泵泵压调到最大,使换向阀频频换向,目的是窜动钻具,松动被固结的钻头。然后,一手持换向阀柄准备给进,一手握离合器,试探转动钻具。在
From 1985 to 1986, we changed the original practice of using powerful pulling tools to cut pipes. We succeeded in handling the horizontal burrs and serious burns many times successfully, speeding up the construction and saving materials and funds . Our experience can be summarized as follows: 1. Once found burned, immediately pull back the drill, open the rig (SGZ-1 type) clutch, to avoid new mechanical accidents. Valve to push back to the end position, stop drilling tool back to prevent the movement of machinery. 2. Analysis of the cause of the accident, do a good job before the preparatory work. 3. The pump pump pressure to the maximum, so that reversing valve frequent commutation, the purpose is to move the drill, loose the drill was consolidated. Then, a hand-held reversing valve handle ready to feed, one clutch, test rotation drilling. in
