An underground turbine generator is a safe and reliable power supply equipment of high precision, high reliability, and long life in mine and other mine drilling measurement instruments. Because of the current problems of low output power and high energy loss of underground turbine generators in general, a set of coalmine underground turbine generators is initially designed by modeling the turbine with CREO software and numerical calculation with ANSYS CFX software, the optimal hydraulic model was determined by considering multiple factors in rotor and stator geometry size, taking the output power as the objective function and optimizing it by using orthogonal experimental method. By comparing the downhole turbine generator model before and after optimization, it was found that the optimized flow line distribution and pressure distribution were well improved. At the same time, the work capacity of the drilling fluid on the turbine was improved. Among them, the output power is positively correlated with the hub ratio, stator inlet angle, and distance between the stator and rotor. On the contrary, it negatively correlated with the rotor number. This conclusion has important guiding significance for optimizing the hydraulic performance of underground turbine generators.
