Manufacturing Process of the 200QJ Deep Well Submersible Pump

The production of the 200QJ Deep Well Submersible Pump adheres to stringent quality control protocols and utilizes advanced manufacturing techniques to ensure superior product performance and reliability. The process encompasses several critical stages, from material selection to final testing.

Detailed Process Flow:

1. Material Sourcing & Quality Inspection: High-grade raw materials are procured, including stainless steel for pump casings, shafts, and impellers (e.g., AISI 304/316 for corrosion resistance, special alloys for aggressive media). Copper windings for motors and insulation materials are rigorously inspected to meet international standards (e.g., ASTM, DIN).
2. Casting & Forging: Components such as impellers, diffusers, and certain motor parts are precisely cast from selected alloys or forged to enhance structural integrity and mechanical properties. This ensures high strength and wear resistance, crucial for the pump's service life in abrasive conditions.
3. CNC Machining & Precision Engineering: Critical components like pump shafts, bearing housings, and impeller bores undergo advanced CNC machining. This process guarantees extremely tight tolerances, superior surface finishes, and perfect alignment, which are vital for hydraulic efficiency, reduced vibration, and extended bearing life.
4. Motor Winding & Assembly: The submersible motor is meticulously wound with high-quality copper wire, insulated, and impregnated with varnish to ensure electrical integrity and thermal stability. The stator and rotor are balanced, and the motor is then sealed, often with a non-toxic, food-grade oil or water fill, for efficient cooling and lubrication.
5. Pump Section Assembly: Impellers, diffusers, and intermediate casings are carefully stacked and assembled on the pump shaft. Advanced hydraulic design principles are applied during assembly to ensure each stage contributes optimally to the overall head and flow characteristics. Dynamic balancing of impellers is performed to minimize vibration.
6. Sealing & Protection: High-integrity mechanical seals (often silicon carbide or tungsten carbide) are installed to prevent water ingress into the motor chamber, ensuring long-term reliability. External coatings or specialized treatments may be applied for enhanced corrosion resistance.
7. Performance Testing & Quality Assurance: Each finished 200QJ Deep Well Submersible Pump undergoes rigorous testing in accordance with international standards such as ISO 9906 (Centrifugal pumps - Hydraulic performance acceptance tests) and ANSI/HI 11.6 (Rotodynamic Submersible Pumps for Hydraulic Performance). This includes:
   • Hydraulic performance curve verification (Head, Flow, Efficiency)
   • Motor electrical performance (Power consumption, Current, Voltage, Insulation resistance)
   • Vibration and noise levels
   • Pressure and leakage tests
8. Packaging & Dispatch: Pumps are carefully packaged to prevent damage during transit, typically using robust crating with appropriate protective materials. Documentation, including installation guides and test certificates, is included.
