摘　　要：针对大型潮流能发电机水下密封的问题,设计真空离心灌封装置,分析在不同离心转速下的灌封结果,对聚氨酯灌封后的定子进行浸泡实验和耐水压试验。结果表明,离心灌封装置转速为200 r/min,定子表面灌封胶层的粘附强度、厚度、密实度、硬度满足要求;经过浸泡实验和水压试验,发电机定子绝缘性能满足要求,密封达到预期目标。For the sealing of underwater large-scale tidal current generator,polyurethane pouring material was used,vacuum centrifugal sealing device was designed,and sealing results under different rotate speeds of centrifugal device were analyzed.Immersion test and hydrostatic test of the sealing generator stator were conducted.The results showed that adhesion strength,thickness,compactness and hardness met the requirement completely.After immersion test and hydrostatic test,the insulation performance of generator stator met the requirement,and the sealing reached the expected target.
