众所周知,密封是潜水电泵的核心,是潜水电泵的关键技术所在,没有一个好的密封设计,再好的潜泵设计都将失去基础。同时,密封技术的落后,也是我国潜泵和国外的主要差距之一。本文拟就小型下吸式潜水 As we all know, the seal is the core of the submersible pump, submersible pump is the key technology where there is no good seal design, even the best submersible pump design will lose the foundation. At the same time, the backwardness of sealing technology is also one of the major gaps between China’s submersible pumps and foreign countries. This article is intended for small submersible diving
