摘　　要：离心泵中输送的液体局部压力达到临界压力时,高速旋转过程中液体中会产生气泡。气蚀是离心泵中气泡运动、破裂、聚拢、消失的全过程。简要介绍了离心泵发生气蚀的原因、危害和相应的对策。When the partial pressure of the liquid delivered in the centrifugal pump reached the critical pressure, bubbles were generated in the liquid during the high-speed rotation. Cavitation was the whole process of bubble movement, breakdown, coalescence and disappearance in centrifugal pump. Causes, hazards and Countermeasures of cavitation in centrifugal pumps were briefly introduced.

关 键 词：离心泵 气蚀形成 对策 危害
