摘要
随着煤矿井下水平定向钻进技术的不断发展,定向钻孔直径和孔深不断增加,对螺杆马达的动力源——泥浆泵提出了更高的性能要求。根据大直径深孔钻孔工艺要求,研制了整体履带式的煤矿井下钻探用BLY600/15K型泥浆泵车。该泵车采用了闭式液压系统电液比例控制技术,实现了遥控器控制泵车履带行走、泵量调节、油温监测等功能。试验表明,泥浆泵车性能先进、可靠,满足钻孔工艺要求。
With the continuous development of horizontal directional drilling technology in coal mine,the diameter and depth of directional drilling are increasing, which puts forward higher performance requirements for the power source screw motor of mud pump. According to the technical requirements of large diameter deep hole drilling, BLY600/15 K mud pump vehicle for drilling of underground coal mine was developed. The pump vehicle adopts the electro-hydraulic proportional control technology of closed hydraulic system, which realizes the functions of remote control of pump vehicle crawler walking, pump volume adjustment, oil temperature monitoring, etc. The test shows that the performance of the mud pump vehicle is advanced and reliable, which meets the requirements of drilling technology.
