1. What is the detailed interpretation of the two models, and what are their differences?
| Model Segment | A10VEC60Hz/52WXX-VRF811C04 Explanation | A10VO60DFR1/52L-VUC11N00-S1643 Explanation |
|---|---|---|
| A10VEC / A10VO | Series Identifier: A10VEC = Compact Electro-hydraulic Variable Displacement Pump (integrated electronic control module); A10VO = Standard Axial Piston Variable Displacement Pump (classic industrial-grade series) | Same as left (Different sub-series for specific application scenarios) |
| 60 | Nominal Displacement: 60 cm³/rev (cubic centimeters per revolution) | Same as left (Both share the same core displacement parameter) |
| EC60Hz / DFR1 | Control Type: EC = Electro-hydraulic integrated control; 60Hz = Compatible with 60Hz power supply systems; optimized for frequency-controlled motor drives | D = Dual control (pressure + flow); FR1 = Hydraulic pilot control with pressure compensation (1st-generation optimized valve for stable flow adjustment) |
| 52WXX / 52L | Mounting & Rotation: 52 = SAE 5-bolt flange (complies with SAE J744 Class 5); WXX = Custom mounting configuration (for specific OEM equipment interfaces) | 52 = SAE 5-bolt flange; L = Counterclockwise rotation (viewed from the shaft end) |
| VRF811C04 / VUC11N00 | Configuration Code: VR = Integrated pressure relief + flow control valve; F811 = Valve core material code (wear-resistant alloy); C04 = Pressure setting (300 bar) | VU = Integrated pressure relief + unloader valve; C11 = Pressure setting (280 bar); N00 = Standard factory calibration |
| – | No additional code | S1643 = Production batch & quality traceability code (records manufacturing date, component batch, and inspection information) |
Key Difference Summary:
| Aspect | A10VEC60Hz/52WXX-VRF811C04 | A10VO60DFR1/52L-VUC11N00-S1643 |
|---|---|---|
| Control Mode | Electro-hydraulic integrated control (compatible with 60Hz frequency conversion drives) | Hydraulic pilot pressure compensation control (mechanical-hydraulic hybrid regulation) |
| Mounting Adaptation | Custom OEM interface (WXX) for designated equipment | Standard counterclockwise rotation (L) for general-purpose installation |
| Valve Configuration | Pressure relief + flow control valve (300 bar setting) | Pressure relief + unloader valve (280 bar setting) |
| Traceability | No batch code (OEM bulk supply) | S1643 batch code (general market traceability) |
