超临界屏蔽电泵用空-水冷却的热屏结构

摘要

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 materi-als. The raw materials were decreased while the axial di-mension of pump set was reduced, to improve the reliability of screened pumps operating under high temperature and pressure.%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。
