What is a Water Well Drilling Rigs? Simply speaking, a water well drilling rig is a mechanical device that drills a water well and completes downhole pipe, well washing, etc., including power equipment and drill bits, drill pipes, core pipes, drill stands, and the like. The following is a brief introduction to the classification and working principle of water well drilling rigs and the correct use of water well drilling rigs.

Water well drilling machine mechanism

1. Hydraulic oil pump: It is a double-type, large displacement pump provides power for the power head. The small displacement pump provides power for four leg cylinders, landing mast cylinders, and afterburning/lifting cylinders.

2. Four legs: The small well drilling equipment consists of a hydraulic cylinder and a fixed frame. The level of the body can be adjusted at the work site to support and stabilize the body.

3. Mast: It is a frame structure welded by giant steel pipe, channel steel and angle steel. The inner groove of the channel steel on both sides is used as the power head to run up and down to ensure the verticality of the hole. The ups and downs of the well mast are completed by hydraulic cylinders.

4. Power head: The mechanism adopting the gear reducer has a large-diameter mandrel in the middle of the low-speed shaft. The upper end of the mandrel can be connected with the hose interface of the concrete pouring equipment to inject concrete; the lower end of the mandrel passes The blue plate is connected to the drill pipe and the drill bit. The high speed shaft is driven by a high torque hydraulic motor.

Classification and working principle of water well drilling rig

Water well drilling rigs can be divided into three categories: rotary water well drilling rigs, impact water well drilling rigs, and composite water well drilling rigs. The former can be subdivided into: large and small pot cone drilling rigs, positive and negative circulation rotary rigs, hydraulic power head drilling rigs, and downhole impact rotary drilling rigs.
