Mechanical equipment for drilling water wells and completing operations such as downhole pipes and wells. Including power equipment and drill bits, drill pipes, core pipes, drill stands, etc. Generally, it is divided into three categories: rotary machine, impact drilling rig, and compound rotary machine. A water well drilling rig is a mechanically driven water well drilling equipment. Its working principle is: the power machine transmits the power to the drilling rig gyrator through the clutch, transmission shaft and gearbox in turn, and then the gyrator transmits the rotary motion of the gyrator to the active drill pipe of the drilling rig through the vertical shaft sleeve, thereby driving the drilling tool. Rotation; the drilling tool relies on the feeding cylinder on the gyrator and its own gravity, and realizes its drilling work by controlling the control valve. When the drilling rig is working, mud is used as flushing fluid (positive circulation); the hoisting system is used to r...
