Feature
Submersible Motor: Dry-type, fully enclosed three-phase asynchronous motor with built-in stator, rotor, and bearing assemblies. The casing is corrosion- and rust-resistant, allowing for long-term submersion.
Pump Body Components: Composed of guide vanes, impeller assembly, impeller housing, and suction chamber. Features a multi-blade design, with corrosion-resistant and wear-resistant materials selectable based on media characteristics.
Sealing Device: Double mechanical seals. The primary seal isolates the media, while the secondary seal prevents leakage. Combined with a pressure relief design in the sealing chamber, it extends seal life.
Control System: Integrates temperature and humidity sensors, and an overload protection module. Supports local control and remote monitoring, providing real-time feedback on motor temperature, winding humidity, operating current, and other parameters.
Application of submersible axial flow pump
Municipal water supply and drainage system
Urban flood prevention and drainage: During the rainy season, submersible axial flow pumps can quickly remove water from low-lying urban areas, underground parking lots, and under overpasses prone to waterlogging, effectively preventing urban waterlogging disasters.
Sewage Treatment Plant: Designed for the conveyance of return sludge in aeration tanks and sedimentation tanks, as well as the lifting and discharge of wastewater within the plant area, suitable for harsh underwater working conditions.
Water conservancy engineering field
Agricultural irrigation and drainage: In plain irrigation areas and low-lying farmland regions, water is drawn from rivers, lakes, or reservoirs for irrigation; during flood seasons, it can also drain accumulated water from farmland to ensure crop growth.
River dredging and water transfer: In conjunction with dredging projects, it involves extracting sediment-laden water flows. It can also be used for large-volume water transfer tasks such as inter-basin water diversion and canal replenishment.
Reservoir and Sluice Integration: As auxiliary equipment for reservoir flood discharge and upstream-downstream water level regulation, it achieves precise water flow control.
Industrial production applications
Thermal power plant circulating water system: In thermal power plants and nuclear power stations, water from rivers or seas is extracted as circulating cooling water to cool the power generation units, ensuring stable operation and low maintenance costs.
Steel and chemical industries: Used for industrial wastewater discharge and cooling water circulation within factory premises. Some corrosion-resistant submersible axial flow pumps can handle media containing acids or alkalis.
Mine drainage: Handling water inflow in mine shafts and transporting slurry during ore beneficiation (requiring pump bodies made of wear-resistant materials).
Port and Ocean Engineering
Port Terminal Drainage: Extract rainwater and accumulated water from the terminal yard and operation areas to ensure the normal operation of the port.
Dry docks and shipyards: Used for filling and draining dry docks to facilitate ship entry for maintenance and exit for launching.
Marine aquaculture: Supplying fresh seawater to aquaculture ponds or discharging wastewater to maintain the circulation and renewal of the aquaculture water body.
