Polymer Concrete Pump Station (Submersible Screw Centrifugal Pump Non-Clogging Type)
مشخصات فنی
Pump type: submersible screw centrifugal pump (equipped with high-efficiency permanent magnet motor, featuring high efficiency, compact size and high power factor, adopting customized precision design to ensure permanent magnets do not demagnetize) Non-clogging characteristics: capable of handling unscreened sewage and industrial wastewater, media containing long fibers and sludge; solids handling capacity approx. 18% (for comparison: vortex type 13%, single-channel impeller 8%, multi-vane centrifugal type 2%) Performance features: high efficiency = low O&M costs; steep performance curve = more stable operating conditions; low NPSH = high self-priming capability; flat power curve = high safety, no overload region Pump station technical specifications: tank diameter 1.2-4.2 m, tank height 2-20 m, inlet/outlet diameter DN80-DN1600, flow rate 10-5200 m³/h, head 5-70 m, pumps 2-4 units Motor: compliant with IE standards, submersible explosion-proof type, with cooling jacket; IP68, insulation class H, motor service factor ≥1.3 Self-cleaning base: screw device base (small inclined bottom-angle inlet guide vanes optimize water inflow, partition walls between pumps provide stability, spiral channel increases water flow rotation intensity to avoid sedimentation and retention) Safety precautions: anti-theft alarm device, safety grille, warning signs, ventilation system
