Water pumps transport liquids through the centrifugal force generated by the rotating impeller. The impeller's speed (typically 1500-3000 rpm) flings the liquid toward the outer edges, generating high-pressure output. Simultaneously, negative pressure (vacuum levels up to 0.08-0.095 MPa) is created in the center, enabling continuous water absorption. Centrifugal pumps, the mainstream type, boast efficiency rates of 60-80% and are suitable for municipal water supply (pressure range 0.2-1.6 MPa) and industrial circulation systems. Submersible pumps, with an IP68 waterproof design and a head of up to 200 meters, are specifically designed for deep well pumping and flood control drainage. Progressive cavity pumps utilize precise screw meshing (clearance 0.1-0.3 mm) to transport high-viscosity media, making them particularly suitable for the petroleum and chemical industries.
Automatic control systems utilize liquid level sensors (accuracy ±1 mm) for intelligent start and stop functions, saving over 30% energy. They are widely used in agricultural irrigation (covering areas up to 500 mu) and sewage treatment plants (with a daily processing capacity of 100,000 tons).
