Brief characteristics of the underground hole drill rig with open-air rig and downhole drilling rig of the points, so today small to explain your use of downhole drilling rig it. A downhole drilling rig can be used in the new open hole concrete load-bearing walls, windows, air conditioning, smoke machines, water heaters and other types of reserve drilling, pipe openings and ventilation, fire drill pipe, duct openings, wall surface removal, floor removal, drilling, reinforcement drilling; Φ10mm-Φ300mm direct drilling, and a variety of sized hole through the wall. II. You can punch in road, highway, railway, bridge, bridge, playing ventilation holes, the water hole, pipe roof drilling machines, various pipelines hole, road open trunking III. Drilling and installation of anchor bolts, fixed all types of large cement surface drilling equipment, using advanced diamond drill bits, cutting equipment, fast drilling in concrete, stone only, brick walls, openings, to better meet the different requirements of construction. Problem well drilling rig daily work often appears as a multi-purpose drilling rig tire type full hydraulic drilling machine, with advanced structure, easy to use, auxiliary time is short and so, but in the course of daily use will inevitably be some failures, which Xiaobian to sort out some of these common symptoms. 1, the hydraulic system is often first appear insufficient pressure. 2, the oil tank is too small or pump damage caused by high oil temperature of hydraulic system failure. 3, the viscosity of the oil pump too high or too low causes fever and severe wear. 4, the brake band on the inner surface oil slick caused by skidding winch brake. 5, rig power machine with slip clutch assembly coaxial heat caused by couplings, pipe roof rig quote, flexible ring excessive wear. 6, friction or excessive wear and tear caused by the compression spring aging or broken clutch slipping. These are the common failure, water well drilling rig itself compact structure, strong integrity, because the complexity of the production and operation to increase the difficulty of routine maintenance, so routine maintenance should be cautious to avoid failure problems delayed production schedule.
