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 couplings cause fever, excessive wear elastic ring. 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 Shandong submersible drilling rig, to avoid failure problems delayed production schedule . Blasting rigs working principle and structural analysis have many friends rigs for blasting works is not very understanding, the following small series for everyone to be a detailed description: the role of atmospheric pressure, circulating liquid from the settling tank through the return ditch along the wellbore The annular gap flow to the bottom, because the turntable drive drill, drill driven by rotation of the drilling pneumatic submersible drilling rig, built by the mud pump suction vacuum the debris mud suction lumen DTH drill rig, then rose to tap into the sedimentation tank by slurry pump submersible drilling rig, the circulating fluid continues to flow after precipitation wellbore, so again and again, forming a reverse circulation drilling work. Mud or water from the drill pipe into the outflow from the wellhead. Positive cycle blasting rig. Mud or water from the drill pipe sucked out from the wellhead inflows. For the reverse circulation drilling machine. Refers to reverse circulation drilling fluid (mud or water) in the drilling machine cycle ways to say, the drilling machine drill drilling time will have to produce sediment, slag stone, by reverse circulation can take the mud these scum to the ground, and then through the mud after the settler back to drilling. Thus, the continuous cycle, and finally into the hole. Reverse circulation can bring a larger diameter slag.
