Máy bơm nước chìm thoát nước công suất lớn, chịu tải nặng 1000QGSW-125
The principle of the fully-flow submersible electric pump lies in its impeller being integrated within the motor's rotor cavity, forming a single unit where the rotor functions as the pump's impeller housing. This design transforms the motor's non-working section into an active component. During operation, water flows through the rotor cavity, preserving the submersible pump's advantages of low investment, compact structure, easy installation, low noise, and efficient heat dissipation. With water flowing directly in and out, the fully-flow submersible electric pump delivers superior hydraulic performance, smooth flow channels, and high overall efficiency.
Flood Control and Drainage: The low-lift, high-flow design is suitable for rapid drainage from urban rainwater pumping stations and water conservancy flood control pumping stations.
Agricultural Irrigation: High-flow water intake supports farmland irrigation, meeting the needs of integrated irrigation and drainage.
Urban Circulating Water: Used for landscape water bodies and river circulation, improving water resource utilization.
Special Terrain Projects: Flexible installation methods (vertical, horizontal, and inclined) adapt to complex terrain and simplify pumping station structure.
The water quality is mild sewage, allowing particles with an equivalent diameter of ≤1/10 of the nominal diameter to pass through, and without a large amount of fibrous debris.
Technical Features
The principle of a full-thru submersible electric pump is that the pump impeller is embedded in the inner cavity of the motor’s rotor, forming an integral unit with the rotor. The inner wall of the stator acts as the pump’s impeller housing, turning the inactive portion of the motor into the active part. During operation, water flows through the inner cavity of the rotor. This device retains the advantages of a submersible electric pump, such as low investment, compact structure, easy installation, low noise, and excellent heat dissipation. Because water flows directly in and out, the full-thru submersible electric pump features excellent hydraulic performance, smooth flow, and high installation efficiency.
(1) Wet-type stator structure, no need for winding sealing
The coils in the wet-type stator winding structure are made of specialized water-resistant winding wire, impervious to water immersion. This eliminates insulation safety issues caused by water leakage due to poor sealing. Reliability is significantly higher than that of existing dry-type stator submersible electric pumps.
(2) Compact Structure with Reduced Dimensions
With its small size and compact structure, the axial dimension is nearly halved compared to traditional dry-type submersible axial flow pumps. Lightweight design with 40% reduction in metal consumption enables rapid installation. Supports diverse engineering applications including vertical, horizontal, and inclined configurations, simplifying pump station structures. Particularly suitable for dual-purpose pumping stations combining irrigation and drainage. Horizontal through-flow installation is primary, though inclined or vertical mounting is also feasible. This project employs horizontal gate installation.
(3) The efficiency of the pump assembly has been significantly improved.
Water flows through the system with minimal bends and irregular pipe configurations, resulting in uniform velocity distribution and smooth flow patterns. Localized losses are greatly reduced, and the short flow path further minimizes flow losses, leading to a marked increase in assembly efficiency.
(4) Exceptionally low noise levels and excellent heat dissipation conditions
Operating conditions are significantly improved, featuring superior underwater heat dissipation, low noise, and minimal environmental impact.
(5) The pump is easy to operate and facilitates automatic control. It requires minimal foundation excavation and has a short construction period.t and reducing space.
It is evident that the fully submersible electric pump is a highly efficient, reliable, and resource-saving product, primarily used in low-head, high-flow hydraulic projects for motorized drainage and irrigation, flood control, and drainage.
