Principles and core advantages of deep well pump technology
Deep well pump is a special type of pump designed specifically for the development of deep groundwater sources. Its core working principle is based on the combination of centrifugal force and fluid dynamics: the multi-stage impeller at the lower end of the pump shaft is driven by a motor to rotate at high speed, and the water body moves from the center of the impeller to the edge under the action of centrifugal force. After obtaining dynamic energy, it is converted into pressure energy through guide vanes and gradually lifted to the surface. Compared to ordinary water pumps, deep well pumps have three major technical advantages:
High head characteristic: By connecting multiple impellers in series (2-10 stages), it is possible to achieve water delivery with a lift of 10-500 meters, meeting the demand for extracting well water at a depth of 100 meters;
Compact underground installation: The pump body diameter is only 50-300mm, compatible with standard well pipes (such as 100mm/150mm/200mm diameter), and the minimum installation clearance is only 20mm
High efficiency conversion: Adopting a large channel impeller design and wear-resistant coating technology, the efficiency of the clean water pump can reach over 80%, saving 15% -20% energy compared to traditional centrifugal pumps.
Deep analysis of application scenarios across the entire industry
In the field of agricultural irrigation
Drip irrigation/sprinkler irrigation system: Select submersible pumps with a flow rate of 10-50m ³/h and a head of 50-100m, and use pressure sensors to achieve constant pressure water supply, with a water-saving rate of 40%
Drought resistance in arid areas: The vertical long shaft pump, combined with a frequency converter, can automatically adjust the flow rate according to soil moisture, and the daily irrigation area of a single pump can reach 200 acres
Industrial production scenarios
Mining: The horizontal deep well pump is equipped with wear-resistant rubber impellers to process mine water with a sand content of ≤ 1500g/m ³, with a continuous operating life of over 8000 hours
Chemical industry: Stainless steel 316L material pump body+fluoroplastic seal, resistant to strong acids (pH ≤ 2) and strong alkalis (pH ≥ 13), used for conveying chemical raw material liquids
Municipal and Civil Scenarios
High rise building water supply: multi-stage submersible pumps are used in series to achieve secondary water supply for 300 meter super high-rise buildings, and pressure tanks are equipped to stabilize water pressure
Emergency drainage: diesel engine driven deep well pump (flow rate 200-500m ³/h), assembled within 30 minutes, suitable for urban waterlogging rescue
