The mud motor is mainly composed of drive head, bearing assembly, universal joint, rotor, stator and bypass valve.
The motor part is composed of a stator and a rotor. The drilling fluid pumped into the drilling tool flows through the motor to drive the rotor to rotate and then flows through the drill bit. The rotational force of the rotor is transmitted to the drill bit to drive the drill bit to rotate. The bypass valve is to make the circulating fluid bypass the motor.
When there is no circulation or low pump volume circulation, the spring keeps the piston in the upper position. At this time, the hole is opened and the mud can flow into or out of the drill string. The action of the piston depends on the displacement. When the displacement reaches the maximum, the piston is pushed down and seated on the piston seat, the hole is closed, and the drilling fluid flows directly through the motor.
