回转供气机构是潜孔钻机和切削潜孔两用钻机上的连续工作机构,它的质量、效率、寿命及运转情况对钻机的生产效率影响极大。近20年来的生产实践证明,如果回转供气机构能够高效率的正常工作,钻机就能充分发挥其效率,完成预定的生产任务。反之,钻机效率不能充分发挥,台班进尺显著下降。而且,采用何种回转供气机构,对钻机的制造成本也有较大的影响。国外潜孔钻机和切削潜孔两用钻机上,采用直接驱动式回转供气机构是极少的,国内还未用过,但是,直接驱动工作装置在工程机械上如卷扬、行走等机构中已广泛应用,
Rotary air supply unit is a continuous working mechanism on the double-drilled and down-the-hole drilling rig. Its quality, efficiency, life and operation have a great impact on the production efficiency of the drilling rig. Nearly 20 years of production practice has proved that if the rotary gas supply agencies to work efficiently and efficiently, the rig can give full play to its efficiency, to complete the scheduled production tasks. On the contrary, drilling rig efficiency can not give full play, stage significantly reduced footage. Moreover, what kind of rotary gas supply mechanism, the manufacturing cost of the rig also has a greater impact. Foreign DTH drilling and cutting DTH dual-use rig, the use of direct-drive rotary gas supply mechanism is minimal, the country has not been used, but the direct drive of the working device in the construction machinery such as winch, walking and other agencies Has been widely used,
