在金刚石钻进过程中，往往因水量不足或停泵断水而导致钻头微烧或烧毁。这种现象严重影响金刚石钻进技术经济效果。为此，必须认真掌握和控制向孔内送入足够的水量，防止和减少烧钻。为了减少和防止烧钻事故的发生，制造使用了靶式流量警报器，该警报器在现场一年多的使用中，取得了一定的作用。但该警报器所用材料来源缺乏，且零件易磨损，于是我们又重新研制了泵压电极接触警报停车装置。该装置是借助泵压表内扇形齿轮，在泵压的作用下要产生一定程度的摆幅，我们在一定摆幅的 In the diamond drilling process, often due to insufficient water or stop the water pump caused bit micro-burning or burned. This phenomenon seriously affects the economy of diamond drilling technology. To this end, we must carefully grasp and control the amount of water into the hole to prevent and reduce burns. In order to reduce and prevent the occurrence of burnt-out accidents, a target-type flow alarm was manufactured that has been used for more than a year in the field and has played a role. However, the source of the siren was lacking and the parts were worn out, so we reworked the pump-pressure electrode contact alarm parking device. The device is based on the pressure pump table fan gear, the pump pressure to produce a certain degree of swing, we swing in a certain
