Embodiment Construction
[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0032]Embodiments of the present invention: a method for improving the performance of a screw drilling tool, the method improves the performance of the screw drilling tool by improving the motor assembly 2 and the cardan shaft assembly 3 in the screw drilling tool; wherein the motor assembly The stator 2-1 and the rotor 2-2 are combined in a spiral structure, thereby prolonging the lead of the motor assembly 2, increasing the number of stages of the motor assembly and the number of heads of the stator and rotor, and improving the efficiency of the mud pump system. Displacement, so that the output torque and speed of the motor assembly 2 can be increased; at the same time, a certain curvature is set at the lower end of the cardan shaft outer cylinder...
