Shandong water well drilling rig is a new, highly efficient, energy-saving, multifunctional hydraulic drilling machine, mainly used for drilling water wells, monitoring wells, geothermal air conditioning in hole, anchor, Defense projects such as drilling; the wall casing follow up rig DTH drilling technology, loose layer effectively tapping into porous rock layers slow technical problems. The rig is equipped with high-power hydraulic motor Rotary cylinder propulsion and lifting, high air pressure DTH drilling footage high efficiency low consumption. Domestic car-DTH Shandong water well drilling rig is currently the top product.
Shandong water well drilling rigs rely on rotating crushing rock hole of the drill. There are big and small cone drills, forward and reverse circulation Rotary drilling rigs, hydraulic power head drill Downhole vibration Rotary drilling rig. Simple Rotary drilling rig drilling equipment only, structure of Rotary drilling rig drilling apparatus and flushing device is composed of two parts. Shandong water well drilling rig Rotary drilling include drill pipe and drill bit. On behalf of commonly used drill pipe has a diameter of 60, 73, 89 and 114 mm 4. Drill comprehensive drilling drill bits for drilling and loop two categories. Large and small cone water well drilling rig in Shandong province using its tapered drill rotation cutting layers. According to the size are called pot-Cone Drill and small cones, can be driven by human or power. Cut chips into the pot of soil, hoisted to the surface discharge, its simple structure, low efficiency, and can only be used for General soil or sand and gravel in diameter not greater than 10 cm, content is not more than 50% formation. Small tapered orifice diameter 0.55 m, drilling depth 80~100 meters; cauldron of cone orifice diameter of 1.1 meters, drilling depth of 30~40 metres. Shandong water well drilling rig, reverse circulation mud Rotary drilling rigs, which are circular mud washing Rotary drilling rig towers, winches, turntable, drilling, mud pumps, taps and motors and other components. Shandong water well drilling rig operation, engine driven by the gear wheel, driven by the actuating rod drill to 30~90 rpm of the speed rotation broken rock. Mud mud pumped under pressure through the pipe at the top of the faucet into the hollow drill down into bits, by water injection to cool, lubricate the bit; cutting through drill pipe at the bottom perimeter of the channel were taken out, after the settler, mud flow back into the mud pit for recycling. Reverse circulation mud washing Rotary rigs drilling method and structure the same as above, but mud cycle in the opposite: mud into itself from the wellhead at the bottom after the settler, carry the debris of mud from the gravel pump water up through the pipe cavity by bit pumped out of the well, back to the settling tank. Pump-suction reverse circulation in this way. Can also flow from the bottom through the nozzle pump pressure into the pipe cavity, formed to bring cuttings up the flow, said Jet reverse circulation. Drilling rigs can form a high flow velocity in the pipe, emit debris and gravel the ability and fast drilling speed. Apply to soil, sand and pebbles in diameter is smaller than the inner diameter of the pipe loose formations, used drill pipe inner diameter is large, typically 150~200 mm, maximum up to 300 mm. But due to the pump suction or pumping power limits, drilling depth in within 150 metres, depth in chip removal efficiency with up to 50 meters high. Compressor washing Shandong water well drilling rig Rotary drilling rig is in the Rotary Rotary drilling rig with air compressor replace pump, using compressed air instead of mud washed well. Reverse circulation is usually used, also known as air-lift reverse circulation. Compressed air through a gas pipeline to the gas-water mixture in the well room to pipe water mixing, form a proportion less than 1 of aerated water flow. Peripheral ring in drill pipe of the water column under the action of gravity, air pipe flow with rising debris and out of the well, flow sedimentation tank sedimentation flow in gravity flow back into the hole. In depth of this rig is large (50 m), chip capacity larger than the pump suction reverse circulation drill rig or Jet, which applies to the larger depth of drought and water shortage area, and boreal permafrost formations.
Shandong water well drilling rig Rotary drilling mud pumps and air compressors are also available and can be selected according to different flushing methods.
Hydraulic power head drill for water well drilling rig Rotary drilling machine in Shandong province. Driven by hydraulic motor through reducer, and along the Tower moves up and down on the head instead of Rotary drilling rig rotary table and tap, drive drill pipe and drill cutting layers. Large drill bits up to 1 m in diameter drilling of large diameter water well, which is characterized by fast drilling speed, simple handling and logging of drill pipe, extension pipe without upgrading drills, Jane from winches, lifting tackle, rotary table, faucet, Kelly and other parts. Down hole vibration Rotary drilling rig, which is vibration and rotary movement into a combination of a rotary rock drilling rig. Drill bits, vibrator, composed of absorber and the guide tube. Vibrator of vibration drill for conical pendulum movement as a whole. Drill mounted on vibration by rubbing the trap outside of the shell, one hand with vibration frequency of about 1000 rpm, about 9 mm in the horizontal circular vibration amplitude on one hand and then 3~12 around the axis of the vibrator RPM low speed rotation with broken rock, and the pipe does not turn, and absorber to avoid vibration of drill pipe. Use compressed air reverse circulation well, cutting through the center of the vibrator tube and pipe discharge cavity well. The rig is simple in structure, drilling and high efficiency. Hole diameter up to 600 mm, drilling depth up to 150 meters.
