Driller: The working principle of driller

Driller: Driller is mainly used to develop groundwater resources, including domestic water, agricultural water and industrial water, and also suitable for hydrogeological exploration, construction engineering, bridge foundation drilling, etc. The structure type of drilling machine has traction type, truck type and car back machine type. General drilling machine by diesel engine, friction clutch, gearbox, transmission box, transmission shaft, mud pump, clean water pump, vacuum pump, turntable, faucet, winch, hydraulic system, operating mechanism, mast, drilling tools, frame and so on. The driller works by pumping and reverse circulation. Its working principle is that under the action of atmospheric pressure, the circulating liquid flows from the sedimentation tank to the bottom of the well through the return ditch along the annular gap. At this point, the rotary table drives the drill pipe and drives the drill bit to rotate the hole. The negative pressure generated by the mud pump draws the clastic mud into the drill pipe cavity, then rises to the faucet, where it is discharged into the settling tank, where the deposited circulating fluid continues to flow into the hole and forms a reverse circulation drilling operation.

The drilling step is to deploy the right pump. After well completion, dynamic and static water level and corresponding water yield should be measured according to construction drainage in the drilling process. Then determine the total pump head based on the difference between the surface and the dynamic water level and the type of irrigation you use, and the pump flow should not exceed the water flow in the well. According to the above two cases, the corresponding pump should be purchased. Reasonable borehole layout, borehole location layout should be based on the actual local hydrogeological conditions. If there is no hydrogeological data, you can refer to the existing water source Wells nearby as the basis for well layout. In areas where shallow groundwater is not abundant, Wells shall not be drilled blindly; In shallow groundwater rich areas, suitable for farmers to build shallow Wells, but the layout of Wells should not be too close, so as to avoid adjacent water Wells mutual influence. With the correct construction method, there are two construction methods of large hole well: one is large slotting method, artificial excavation or blasting construction; Two, caisson method, drainage construction or not drainage construction. Opposite pumping construction generally adopts mechanical hammer and manual hammer, relying on the gravity of the hammer to drive the straw directly into the ground.
