摘　　要：热屏在屏蔽电泵中能够阻隔泵端的热量传递到电机端,起到保护电机的作用。根据机组轴向尺寸及节省材料的要求,设计了空水冷热屏结构,增强了隔热能力,在减少原材料的同时减小机组的轴向尺寸,提高了高温高压屏蔽电泵的可靠性。The heat shield was used to isolate the heat from pump to motor for protection purpose. Construction of the air-water cooled heat shield was design in accordance with the axial dimension and requirement of saving materials. The raw materials were decreased while the axial dimension of pump set was reduced, to improve the reliability of screened pumps operating under high temperature and pressure.
