The vertical multi-stage long axis semi submersible deep well turbine pump, which is matched with the upgrading and renovation project of the Qiantaigou drainage pump station, is an efficient drainage equipment specially customized for urban drainage conditions. It fully complies with the CJ/T 235-2017 urban construction industry standard and is suitable for the overall renovation positioning of the pump station with a total investment of 29.85 million yuan. It can greatly enhance the regional flood prevention and control capabilities.
Exclusive adaptation characteristics for renovation projects
High flow drainage capacity: After the renovation of the pump station, the flow rate of a single pump can reach 2000-8000m ³/h, which can quickly eliminate the waterlogging caused by heavy rainfall in Huoshan urban area and match the flood control and drainage design standards along the Dongpi River.
Deep water level water intake adaptation: Multiple sections of spliced lifting pipes are designed, and the underwater depth can be flexibly adjusted within the range of 3-20m. It adapts to different water level changes in the pump station collection tank and can stably intake water even during dry seasons.
Quick start without irrigation and water diversion: The vertical downward suction port has a self irrigation effect, eliminating the need for manual pre irrigation and water diversion before each drainage. It can be quickly turned on during emergency drainage during flood season, greatly reducing response time.
High sand content sewage resistance: The guide bearing is made of wear-resistant material such as Sailong/filled polytetrafluoroethylene, and the overcurrent components can be made of high chromium cast iron, which can withstand the wear of sediment and debris in urban rainwater and sewage, and has stronger long-term operational stability.
