Lower valve, lower valve are equipped with the valve opening flowed through for drilling fluid, and the valve opening in lower valve is opposite with the valve opening position in upper valve group.Work as mud
When the cleaner for high-pressure drilling fluid pumped out flows through concussion connector, coupling enters motor sub-assembly, drive rotor is rotated around the axis of stator,
And rotating speed and torque are passed into drill bit by universal shaft component passes to transmission shaft component.When the rotor in motor sub-assembly
Lower valve base mounted thereto is driven to rotate during rotation, the valve opening in lower valve is constantly staggered or overlaps with the valve opening in upper valve group,
The variation of the area of passage generating period of the drilling fluid of helicoid hydraulic motor is passed through, and then generates waterpower pulse.
The utility model has the advantages that compared with prior art：The structure design of the utility model is reasonable, uses
