郑州液压钻机的特点以及分类（Characteristics and classification of Zhengzhou hydraulic drilling machine） Characteristics and classification of Zhengzhou hydraulic drilling machine Hydraulic drilling rig is the most common drilling rig in our country. It is also called oil pressure drilling machine. Below we talk about the characteristics and classification of hydraulic drilling machine: Advantages of hydraulic drilling rig: The pressure at the bottom of the hole can be accurately maintained according to the degree of the pressure indicator; The labor intensity of the workers was greatly lightened during the operation; The utility model can prevent the sudden falling of the drill pipe and bring in and turn over and cause the wounding event; When drilling or handling faults, it can be used as an oil pressure jack; The frame has some mobile tanks, can be automatically removed from the empty gyrator; Some are equipped with the twisting machine, automatic unloading twist drill. The drill is made of diamond, carbide, drill bit and fishtail bit, which can be used for coring drilling and non coring drilling. Classification of hydraulic drills: Rotary drilling machine Rely on the rotary movement of the drilling tool to break the rock formation into holes. There are large and small pot cone drill, positive and reverse circulation rotary drilling, hydraulic power head drill, rotary drill hole vibration etc.. The simple rotary pile driver only has the drilling device, and the perfect rotary pile driver has two parts, the drilling device and the circulating well washing device. The drilling tools of rotary well drilling rig include drill rod and drill bit. The nominal diameters of commonly used drill pipes are 60, 73, 89 and 114 mm in 4 ways. The drill bit and comprehensive drilling annular drilling bit two categories. The big pot, the pot cone cone using rotary drill cutting soil. According to the size of the drill are called cauldron cone and cone pot, can be driven by manpower or power. The
