["J'ai plusieurs types de pompes centrifugeues à auto-suctionement,吸,,但是它们都不是同一个厂家生产的,而且根本没有自吸功能,"

"Ce n'est pas qu elles n'ont 自自吸功能,而是你的泵入口管道上的止回阀漏水,或泵入口管道漏气的问题。在还没有把问题搞清楚之前急着下结论不好 供参考。"

如果灌泵没问题 建议观察液位 液位到达一定程度再试 得一点点摸索 还有坑槽内是否有其他管线

泵选型参数是否有误,另外密度1.83也是影响自吸高度的,选型时是否考虑?

上个图看下,泵没反转吧

这是前面遇到的工况,没有图片了!只是记得是江苏的厂家,但是泵肯定没有反转!杨程不低于20米,流量在30立方左右,设计计算不会有问题,我附近很多单位都反馈自吸泵不给力,我弄不明白是自吸泵本身技术不成熟还是我们选择的泵制造厂家技术不成熟,现在我都不敢用了!

自吸泵如果选型没问题,工艺流程没问题,操作没问题,泵本身无故障没问题,那么就没问题,放心用
