前言 FH_1-915水刹车是我国五十年代进口的与R3200钻机配套的水剎车。这种水刹车在国内数量不少,但近年来由于缺少配件,设备带病运转,造成设备损坏,甚至报废。去年6月份以前,我矿11台水刹车几乎全部损坏;而我矿32524队在钻纳60~#时(井深3186米)又急需FH_1-915水剎车。因此,我们组织有关人员改进修复了两台FH_1-915水刹车。修复的两台水刹车经两口3000多米深井的考验,效果良好,受到钻井工人的好评。
Foreword FH_1-915 water brake is a kind of water brake imported from China in the 1950s and matched with R3200 drilling rig. This kind of water brake is quite a lot in China, but in recent years due to the lack of spare parts, the equipment runs ill, resulting in equipment damage or even scrapped. Last year in June last year, I mine 11 water brakes almost all damage; and my mine 32524 team in the drill 60 ~ # (well depth 3186 meters) and FH_1-915 water brake in urgent need. Therefore, we organized the relevant personnel to improve and repair two FH_1-915 water brakes. Two water brake repair by two more than 3000 meters deep test, the effect is good, well received by drilling workers.
