Convenient Move Reliable Water Well Wheel Mobile Drilling Rig 300m For Countryside Wells

ST300 series Water Well Drilling Rig is a light, efficient and versatile drilling equipment powered by diesel engine from China famous brand. It is mainly suitable for drilling wells, agricultural irrigation wells and other uses, especially for water extraction in mountainous and rock formations engineering.

• Hydraulic automatic feeding mechanism is adopted to improve drilling efficiency and reduce labor intensity
• Ball clamping mechanism or hydraulic chuck is adopted, no need to stop to change the rod - operation is convenient, safe and reliable
• Hashole bottom hole pressure gauge for monitoring situation in the hole
• Compact structure, centralized handle, small floor area, light weight, strong decomposition force and convenient movement - operable in plains and mountains

• Bending moment of drill pipe is too large during reaming and pipe pulling back
• Excessive bending moment causes: actual curve of guide hole deviates greatly from theoretical curve; irregular hole after reaming creates angle between pipe and reamer/drill pipe axis

During the working process of water well drilling rig, the pump is used for reverse circulation operation. Under the action of atmospheric pressure, the circulating fluid flows from the sedimentation tank to the bottom of the well through the return ditch along the annular gap of the well. At this time, the rotary table drives the drill pipe to drive the drill bit to rotate for drilling.
