Technical Specifications

1. Dimensions and Tolerances:
   • Diameter and Length: Exact dimensions vary depending on the specific engine and pump design but typically range from a few millimeters to several centimeters in diameter.
   • Tolerances: Tight dimensional tolerances (in the range of micrometers) are crucial for proper function and fit within the pump assembly.
2. Performance Requirements:
   • Strength and Durability: The shaft must withstand high cyclic loads and pressures typical in common rail systems.
   • Corrosion Resistance: Materials and surface treatments must resist corrosion from fuel and environmental exposure.
   • Precision: High precision in the geometry of the shaft is necessary to ensure proper interaction with other pump components and consistent fuel delivery.

Quality Control and Testing

1. Non-Destructive Testing (NDT):
   • Ultrasonic Testing: Used to detect internal flaws or inconsistencies in the material.
   • Magnetic Particle Inspection: Helps identify surface and near-surface defects.
2. Dimensional Inspection:
   • Coordinate Measuring Machines (CMM): Utilized for precise measurement of dimensions and geometries.
   • Surface Roughness Testing: Ensures the surface finish meets specifications.
3. Performance Testing:
   • Fatigue Testing: Assesses the durability under cyclic loading conditions.
   • Pressure Testing: Verifies the shaft can withstand the operational pressures without deformation or failure.

By combining high-quality materials, advanced manufacturing processes, and rigorous testing, ELKOSO ensures that its common rail pump shafts meet the demanding requirements of modern diesel engines.
