It not only connects the pump body and the pipeline, ensures the smooth transmission of fluid, also bears the key task such as absorbing vibration, compensating the expansion and deformation of pipeline due to thermal expansion and contraction or external force. However, in the actual operation process, with the progress of wastewater evaporation process, the solid content in wastewater gradually increases, and these solid particles or formed crystals cause frequent scouring to the soft connection at the inlet of circulating pump. This scouring effect leads to continuous corrosion and damage of soft connection material, seriously affects the stability and reliability of the system.
