FAQ;
1. Model Interpretation & Core Parameters
Q3: What is the FR control mode’s working principle and typical application scenarios?
A3: FR (Flow Control with Pressure Limiting) is a combined control mode: ① Primary function: Maintains constant flow by adjusting swashplate angle—when system flow demand is stable, the pump automatically compensates for pressure fluctuations to keep flow constant; ② Secondary function: Integrates pressure limiting—if system pressure exceeds the set value (adjustable via control valve), the swashplate retracts to reduce displacement, preventing overload. Typical applications: Concrete mixers, small excavators, and hydraulic presses requiring stable speed (flow-dependent) with overload protection.
Q4: What are the differences between this pump and other A10VSO variants (e.g., A10VSO45DRG)?
A4: Core differences lie in control modes and application focus: ① A10VSO45DFR: FR control prioritizes constant flow, suitable for flow-sensitive systems (e.g., conveyor belts); ②A10VSO45DRG: DRG (Pressure Control with Remote Adjustment) prioritizes constant pressure, ideal for pressure-sensitive scenarios (e.g., clamping devices); ③ Structural difference: FR models have a flow feedback spool, while DRG uses a pressure feedback piston; ④ Cost: FR models are 5-8% more expensive than DRG due to more complex flow control components.
Q5: What hydraulic fluids are compatible, and what are the cleanliness requirements?
A5: ① Fluid types: Standard mineral oil (ISO VG 32-68, e.g., Rexroth HLP 46); optional eco-friendly oil (Rexroth HEES) or water-glycol (HFC) with seal upgrade (order code suffix "FH"); ② Viscosity range: 10-1000 mm²/s (operating: 16-36 mm²/s); ③ Cleanliness: Mandatory NAS 9 class (ISO 18/15); for EO (electronic control) variants, upgrade to NAS 8 class; ④ Moisture content: ≤0.1% (critical for preventing corrosion of the swashplate and piston pairs).
