AI Technical Summary
Technical Problem
[0004]现有真空泵机组的排水口常与循环水槽底部平齐或过低，易出现“水位稍降即排水”的问题，导致循环水快速流失，若补水不及时，会引发抽水泵空转、真空生成中断，甚至因干磨损坏泵体密封件，因此，本领域技术人员提供了一种水喷射真空泵机组，以解决上述中的问题
Benefits of technology
1、本实用新型，当机组运行中循环水因蒸发、微量泄漏导致水位下降，但未低于最低水位线时，出水管无法排出循环水，这些水会持续留存于循环水槽与预制水槽组成的闭环系统内，被抽水泵反复抽取、加压后输送至吸入室，再经扩散管回流至循环水槽，实现“无排水空转循环”，这种设计一方面避免了因水位小幅波动导致的断水停机，确保真空生成过程不中断，尤其适用于间歇式介质处理场景。
