July 24 — due to Typhoon "Cimarron," Xiamen City faced severe flooding, with the Wucun Tunnel experiencing serious water accumulation. Although emergency efforts by the fire department have reduced the water level from 800 meters to 427 meters over three days, the situation is still far from resolved. Today, a newly installed submersible sewage pump has been deployed to tackle the remaining water and mud, marking a crucial step in the rescue operation at Wucun Tunnel.
This is a grand debut for the submersible sewage pump, which has proven its strength in handling thick sludge and debris. As the water recedes, sediment and solid materials are now exposed, making it impossible for regular pumps to function effectively. The submersible sewage pump, however, is designed specifically for such challenging conditions.
Submersible sewage pumps are built as a single unit with the motor and pump integrated, allowing them to operate fully submerged. They can handle long fibers, bags, belts, grass, and other debris, making them ideal for draining wastewater, sludge, and even sticky or viscous liquids.
Compared to traditional horizontal pumps, submersible sewage pumps offer several advantages:
1. **Compact Design**: Since they operate underwater, they can be directly placed in the sump, eliminating the need for a separate pump room and saving space and construction costs.
2. **Easy Installation and Maintenance**: Small models can be manually installed, while larger units often come with automatic coupling systems, making installation and maintenance straightforward.
3. **Long-Lasting Performance**: With a coaxial design and shorter shafts, the load on the bearings is reduced, resulting in longer service life compared to conventional pumps.
4. **No Cavitation Issues**: This feature ensures smooth operation without the risk of damage caused by air pockets or insufficient water supply, providing greater reliability for operators.
Submersible sewage pumps are widely used in municipal projects, industrial settings, hospitals, buildings, restaurants, and construction sites. Their versatility and efficiency make them an essential tool in flood control and wastewater management.
As the Wucun Tunnel continues to recover, the role of the submersible sewage pump highlights the importance of advanced technology in disaster response. Stay tuned with Asia Fluid Network for more updates on this critical operation.
