The Precision Manufacturing Process of the 125QJR Deep Well Submersible Pump

The integrity and performance of the Υποβρύχια αντλία 125QJR βαθιάς πηγαδιού are fundamentally rooted in a meticulously controlled manufacturing process, adhering to international standards to ensure optimal quality and durability. This section details the comprehensive stages from raw material procurement to final product testing.

1. Raw Material Procurement and Inspection:

Only high-grade materials are sourced, including stainless steel (e.g., AISI 304, 316, or Duplex Stainless Steel for enhanced corrosion resistance), cast iron for specific components, and specialized elastomers for seals. Each batch undergoes rigorous incoming inspection to verify chemical composition, mechanical properties (tensile strength, hardness), and adherence to international material standards like ASTM and EN specifications. This initial step is crucial for the structural integrity and resistance to abrasive and corrosive media typical in deep wells.

2. Component Fabrication and Machining:

• Casting & Forging: Impellers, diffusers, and certain housing parts are precision-cast or forged from selected stainless steel or durable cast iron alloys. This process ensures high density, excellent wear resistance, and the structural strength required to withstand high pressures and dynamic loads.
• CNC Machining: Critical components, including shafts, bearing housings, and motor parts, undergo advanced CNC (Computer Numerical Control) machining. This achieves micron-level tolerances, essential for minimizing vibrations, optimizing hydraulic efficiency, and ensuring precise alignment during assembly. This precision directly contributes to the pump's impressive energy-saving characteristics and extended service life, which can exceed 10 years with proper maintenance.
• Welding: Automated welding processes, often using TIG (Tungsten Inert Gas) or Laser welding, are employed for joining stainless steel components, ensuring strong, corrosion-resistant seams that maintain the pump's hermetic seal.

3. Motor Winding and Assembly:

The submersible motor, a core component, is wound with high-grade copper wires, insulated with water-resistant materials, and encapsulated in a robust, hermetically sealed casing. Precision balancing of the rotor minimizes vibration and extends bearing life. The entire assembly process occurs in a controlled environment to prevent contamination.

4. Final Assembly:

Pump and motor sections are carefully integrated, with critical seals and bearings positioned for optimal performance. Lubrication systems are checked, and all mechanical connections are secured according to strict torque specifications.

5. Quality Control and Testing Standards:

Every Υποβρύχια αντλία 125QJR βαθιάς πηγαδιού undergoes rigorous testing to guarantee performance and reliability:

• Hydraulic Performance Testing: Pumps are tested against specified flow rates and heads to confirm conformity with design curves, adhering to ISO 9906 (Centrifugal, mixed flow and axial pumps - Hydraulic performance acceptance tests - Grades 1, 2 and 3).
• Motor Electrical Testing: Voltage, current, power factor, insulation resistance, and dielectric strength are verified according to IEC 60034 standards.
• Leakage and Pressure Testing: The entire assembly is subjected to hydrostatic pressure tests to ensure absolute leak-tightness, critical for submersible operation.
• Vibration Analysis: Dynamic balancing tests are performed to minimize vibration, extending bearing and mechanical seal life, compliant with ISO 10816.
• Endurance Run: A final operational test simulates real-world conditions to detect any potential defects under continuous load.

These stringent procedures ensure that the Υποβρύχια αντλία 125QJR βαθιάς πηγαδιού delivered to our clients is not only compliant with international quality benchmarks but also engineered for maximum service life and minimal operational disruptions.
