The rotary water well drilling rig mainly relies on the rotary motion of the drilling tool to break the rock formation and form the hole. Common ones include large and small pot cone drilling rigs, forward and reverse circulation rotary drilling rigs, hydraulic power head drilling rigs, down-the-hole vibration rotary drilling rigs, etc. A simple rotary drilling rig only has a drilling device, while a well-structured rotary drilling rig consists of a drilling device and a circulating well cleaning device. The drilling tools of rotary table water well drilling rig include drill pipe and drill bit. Commonly used name of drill pipe,There are 4 diameters of 60, 73, 76, 89, 102 and 114 mm. Drills are divided into two categories: drills for full drilling and drills for annular drilling.
The large and small pot cones use their pot cone drills to rotate and cut the soil layer. According to the size of the drilling tools, they are called large pot cones and small pot cones, which can be driven by manpower or power.
The rotary drilling rig commonly used in positive and reverse circulation mud washing rotary drilling rigs, namely the rotary drilling rig with positive circulation mud washing, is composed of a tower, a hoist, a rotary table, a drilling tool, a mud pump, a faucet and a motor. During operation, the power machine drives the turntable through the transmission device, and the drill bit is driven by the active drill pipe to rotate and break the rock formation at a speed of 30-90 rpm.
