How does the screw drill achieve drilling operations

The screw drill is a positive displacement downhole power drilling tool that converts the hydraulic energy of drilling fluid into mechanical energy. When the mud pumped by the mud pump flows through the bypass valve and enters the motor, a certain pressure difference is formed at the motor's inlet and outlet, driving the rotor to rotate around the stator's axis. The rotational speed and torque are then transmitted to the drill bit via the universal joint and drive shaft, enabling the drilling operation.
