1. What is the detailed interpretation of the model “A10VG45DGDM1/10R-NSC10F023S-S”?
| Model Segment | Technical Explanation |
|---|---|
| A10VG | Series Identifier: Axial Piston Variable Displacement Pump (Designed for closed-loop hydraulic systems, industrial-grade heavy-duty performance for mobile and stationary applications) |
| 45 | Nominal Displacement: 45 cm³/rev (cubic centimeters per revolution, indicating the volume of hydraulic fluid displaced per shaft rotation) |
| DGDM1 | Control Type: D = Dual control (pressure + flow); G = Enhanced damping configuration (reduces pressure fluctuations); DM1 = Dual-mode regulation (pressure + flow control with electronic feedback compatibility) |
| 10R | Mounting & Rotation: 10 = SAE 1-bolt flange (complies with SAE J744 Class 1, compact mounting interface); R = Clockwise rotation (viewed from the shaft end) |
| NSC10F023S | Configuration Code: NS = Integrated safety valve; C10 = Relief valve pressure setting (250 bar); F023 = Production batch code; S = Enhanced wear-resistant coating (for harsh working conditions) |
| -S | Supplementary Configuration: Second “S” denotes special sealing design (high-temperature and high-pressure resistant seals) |
