The role of the four agencies function of composition Water well drilling rig is to complete the well pipe, wash well and other operating machinery and equipment, the four institutions which are mainly composed of about four parts; a power head, water drill rig completed perfusion utility portion of concrete, using gear box mechanism, low-speed shaft in the middle of a large hole in the spindle, catchy may, under the port connected to the drill pipe, drill and hose connectors at concrete pouring device through the flange; 2, hydraulic pumps, pipe roof rigs, power function is to provide support to the power head, pipe roof rig parameters, the composition of the duplex; 3, a drill mast, pipe roof drilling rig manufacturers, function is to ensure the verticality of the borehole, the structure constitutes a giant steel pipes, channels and angles welded combination; 4, four legs frame, composed by a hydraulic cylinder and holder, adjust the level of the body's role to support and stabilize the body at the scene; the development process of well drilling early in the year 2nd century ago, China has used bamboo bow stretch manpower and with the impact of the cone drill formations and drilling rigs original impact, then the long-term use in rural China. To the 1950s, we introduced from abroad rope hammer drill, in the early 1960s began to develop large pot cones, red cones and other simple drilling rig caught. 1966 years ago began to develop positive cycle rotary drilling rig, pipe roof drilling rig prices, after 1974 years ago, the successful development of reverse circulation rotary drill rigs and complex, in the late 1970s created a DTH vibration rotary rig. Europe and the United States in the 19th century, the main use of rope hammer drill, in the 1860s, the French-first-use dial rotary drilling rig, later spread to America and rapid development. In the 1950s, it began to develop reverse circulation rotary turntable rig, and later appeared with compressed air instead of mud wash well as media rotary turntable rig, to 70 years the development of hydraulic power head rotary drilling rig.
