| Summary: | Turbodrills are extensively utilized within the oilfield development industry. In order to enhance the performance output of turbodrills, a novel stator and rotor structure has been conceptualized. Fluent 19.0 numerical simulation software was employed to ascertain the output characteristics of the rotor within the flow field. The drilling engine output performance was the subject of a qualitative study, which was conducted using the drilling mud pump test equipment during drilling. Furthermore, a speed torque meter measurement system was designed to quantitatively analyze the output torque and speed performance of the prototype. The results show that: ① Through the numerical simulation method, it is verified that the new structural rotor has the output performance of a conventional rotor. ② Comparing the numerical solution and the test value, it can be seen that the relative error value is within 4.3%, indicating that the numerical simulation has a certain accuracy. ③ When the inlet displacement is 30 L/s and the speed is 1400 r/min, the maximum value of the numerical solution of the output torque of a single rotor group is 12.45 N/m. When the inlet displacement increases from 18 L/s to 30 L/s, the maximum torque numerical solution increases from 10.78 N/m to 27.44 N/m. |
