为给煤矿井下大功率深孔定向钻探设备提供泥浆介质,研制了煤矿井下新型钻探设备——BLY390型煤矿井下履带式泥浆泵车。该泵车立足于大功率设备多体化的思路,克服大功率钻机外形尺寸增大带来的使用和运输不便的问题,采用负载敏感液压技术,解决了单独的泥浆泵对定向钻探负载适应性差的问题。应用实践表明,BLY390型泥浆泵车搬迁便捷、钻场适用性强,输出流量大、压力高,可满足瓦斯抽采、防治水、顶底板治理以及大直径高位钻孔等各种钻孔对介质的需求。
In order to provide mud medium for high power deep hole directional drilling equipment in coal mine, a new type of drilling equipment - BLY390 coal mine track mud pump truck was developed. The pump car based on the idea of multi-body high-power equipment to overcome the use of high-power rig dimensions and transport inconvenience caused by increased use of load-sensitive hydraulic technology to solve a separate mud pump directional drilling load poor adaptability The problem. Application practice shows that BLY390 mud pump truck is convenient to move, has strong applicability of drilling field, high output flow rate and high pressure, and can meet various drilling mediums such as gas drainage, prevention and control water, roof and floor treatment, The demand.
