Submersible axial flow pumps are suitable for irrigation and drainage pumping stations. They offer high flow rates, low head, and are suitable for conveying raw water or light sewage. They can be used at temperatures below 50°C and head levels below 10 meters. They are simple to operate and use. With the installation system, they can be built into underground pumping stations, preserving the surface. They are ideal for locations along rivers and lakes with significant water level fluctuations, providing a comprehensive solution for flood control.
Power: 15-2500 kW
Head: 1-10 m
Flow: 350-50,000 m³/h
Applications and Features
The QZ submersible axial-flow pump is an upgrade to the traditional split-unit unit. The motor driving the pump is a dry, fully enclosed, submersible three-phase asynchronous motor. This unit’s pump and motor are coaxially integrated, enabling long-term submersible operation. It offers a range of advantages unmatched by traditional units. Because the pump and motor are integrated and submersible, the labor-intensive and time-consuming on-site assembly process of aligning the pump and motor axes is eliminated, making on-site installation convenient and fast. Submersible operation significantly simplifies the pump station’s civil engineering components, reduces installation floor space, and saves 30%-40% of the total construction cost. Submersible operation offers low noise levels, improved motor cooling, and zero high temperatures and noise interference within the pump station, improving the station’s operating environment. Furthermore, fully underground pump stations can be constructed as required, preserving the surface environment. Operation is flexible, allowing the unit to be started and stopped at any time, eliminating the need for pre-startup lubrication of the pump’s rubber bearings. Remote and automatic control are readily available. The unit is easily disassembled and maintained. The use of this unit is a solution to flood control problems in riverside and lake areas with large water level fluctuations. It eliminates the long shaft between the pump and the motor, thus improving operational reliability.
Operating Conditions
· Power supply, 50 Hz frequency, 380 V three-phase AC power
· Water temperature not exceeding 40°C
· Water pH value should be between 5.5 and 8.5
· The pump must be fully submerged in water, with the submersion depth not less than 0.8 meters.
Supporting Electric Cabinets
1. Step-Down Voltage Starter (9.2 kW – 410 kW): This cabinet offers low inrush current and voltage drop during startup. However, due to the impact on the power grid, it is not suitable for frequent starting.
2. Soft Starter (2.2 kW – 410 kW): Soft starters offer low starting current and no impact on the power grid, making them suitable for frequent starting. They also feature phase loss and overload protection.
3. Variable Frequency Starter (7.5 kW – 500 kW): This cabinet offers comprehensive functionality, with protection for short circuit, phase loss, three-phase imbalance, overload, and water shortage depending on the model.
