| Abstract: | Nowadays,the current hydraulic design of submersible sewage pumps is traditional and single,however mechanical seal leakage problems still exist after operating underwater for a long time.Furthermore,its efficiency is not high,operation reliability is poor and accidents occur frequently.Therefore,this paper offers multi-operating condition hydraulic design method and double sealed chamber structure design of submersible sewage pumps.The performance of the pump is greatly optimized,operation reliability is strengthened a lot.Meanwhile,the average efficiency is higher than the domestic similar products from 5% to 10%,and the energy saving effect is notable as well. |
