Small drilling machinery rely gravel from the rotational movement of drilling. A large pot cone play, forward and reverse circulation rotary drilling fight, hydraulic driving head hit machine, DTH play vibration rotary machine. Only a simple rotary drilling playing computer equipment, improve the structure of rotary drilling machine to play two parts, recycling washing equipment consisting of well drilling equipment. Auger playing computer, including rod and starts playing. Nominal diameter rod generally have four kinds of play and 114 mm 60,73,89. By playing a game of heads and full-ring play two categories. Suitable soil, sand and gravel 300 drilling machine how to sell, generally smaller than the diameter of the rod loose play ground, playing pipe inner diameter and the inside diameter, usually 150? 200 mm 300 drilling machine service life, up to 300 mm. However, due to inhalation or squeeze pump capacity constraints, drilling depth is generally less than 150 meters and a depth less than 50 meters high chip removal efficiency. We often hear the impact of playing computer and playing computer DTH, in fact, the principle is the same. Most of the works are based on playing computer and playing computer rotation into technology. Usually small drilling machine can also be used from the beginning through the nozzle at the bottom of the pressurized spray chamber, formed to carry cuttings to fight rising pump water to the spray reverse circulation. It can rise higher rate, a strong ability to discharge debris and pebbles to form a drilling rig in the rate. Several common drilling machine: Impact drilling machine is the impact drill with a rope to the well site, by the power means for driving the percussion mechanism and drive up and down the rope and impact drill, chisel crushed rock and drilling. This is an ancient method of drilling, equipment is simple, low cost, but drilling and fishing ballast must alternate 300 drilling machine image, so slow drilling speed. Rotary drilling machine is powered by a turntable 300 drilling rigs, drill pipe and drill together to drive the rotary cutting, grinding and drilling geotechnical borehole with the drill continues to lengthen and deepen, with the circulating mud cuttings brought to the surface . It is faster than the impact drilling machine drilling speed, and ease of handling the situation well collapse. Composite drilling machine is affixed on a red rotating drill hole, using a circulating fluid or gas driven rotary drill punch mandrel, while the impact of the drill movement and rotation of two broken rock and drilling. 300 drilling machine life, Prius old brand, a county 300 drilling rigs provided by Luoyang Prius Drilling Equipment Co., Ltd.
