Without large drilling engineering crawler drilling machine , which greatly improves the performance of drilling speed and efficiency, particularly in remote areas of crawler drilling machine crowd is more widely used, but for which work has many friends don't know, will give members a detailed description below.
So how do crawler drilling machine work?
Crawler works by pump suction reverse circulation drilling machines. It of work principle is in atmosphere pressure of role Xia, cycle liquid by precipitation pool by back ditch, along wells of ring clearance flow to bottom, because at of turntable drive drill pipe, led bit rotating for drilling, by pump pumping sucking established of negative pressure put debris mud inhalation drill pipe within cavity, then rose to taps, by pump row into precipitation pool, precipitation Hou of cycle liquid continues to into well hole, such so cycle, formed has anti-cycle of drilling work.
Mud or water enter from the drill pipe, flow from the wellhead. For normal circulation drilling machines. Mud or water sucked out from the drill pipe, inflow from the well head. For reverse circulation drilling machines. Direct and reverse circulation refers to the drilling fluid (mud or water) cycle in the crawler drilling machine said, crawler drilling machine drill drilling produces slag, slag stone, through positive and negative cycle may be brought to the ground by mud slag, after settler mud again to go back to drilling. This constant loop, the last hole. Slag can take larger diameter reverse circulation.
