Description

technical field [0001] The invention relates to a method for simulating a temperature field of a submersible motor based on Ansys Workbench, and belongs to the technical field of temperature field simulation of a submersible motor. Background technique [0002] Excessive temperature rise of the submersible motor will affect its operating state, and will shorten the life of the insulating material with weak heat resistance inside the motor, or even burn it out. Accurate calculation of its temperature field has practical significance. Because submersible motors generally work in 2000-3000m deep oil wells, their working environment is harsh, and factors such as structure and heat dissipation conditions are relatively complicated, which brings certain difficulties to the calculation of temperature. At present, the traditional methods for analyzing the temperature field of submersible motors are all considered as a whole, and the calculated results are mostly average values. Th...
