The difference between sewage pump and submersible pump1. Structural differences:Sewage pump: Due to its need to handle media containing solid particles such as long fibers and paper scraps, its design focuses more on anti clogging and stability. The structure of sewage pumps is relatively complex t

The working principle of a centrifugal pump is to drive the impeller to rotate at high speed through an electric motor, causing the liquid to generate centrifugal force. The liquid is then thrown into the side channel and discharged outside the pump or into the next stage impeller under the action o

Reasons for the increase in copper prices1‌. Supply and demand relationship: The growth rate of global copper mine supply has slowed down, and it is expected to only increase by 2.2% in 2025. At the same time, China has tightened regulations on the construction of new copper smelters, further limiti
