    Structure composition and configuration of small water well drilling rig?


    1. Hydraulic oil pump: it is double connected type. The large displacement pump provides power for the power head, and the small displacement pump provides power for four outrigger cylinders, landing mast oil cylinders and afterburner / lifting pulley oil cylinders.

The upper port of the mandrel can be connected with the rubber hose interface of the concrete pouring equipment to pour concrete; the lower port of the mandrel is connected with drill pipe and drill bit through flange. The high speed shaft is driven by a high torque hydraulic motor
