PVH141 Variable Axial Piston Pump
| Theoretical Displacement | ~141 cm³/rev (cubic centimeters per revolution) | Defines the maximum oil volume the pump can discharge per shaft rotation (varies slightly by manufacturer calibration). |
| Maximum Continuous Pressure | 30 – 35 MPA (4350 – 5075 PSI) | Safe long-term operating pressure; ensures pump durability without component damage. |
| Peak Pressure | 38 – 42 MPA (5510 – 6090 PSI) | Short-duration (≤5วินาที) pressure for emergency or heavy-load scenarios (avoid prolonged operation at peak pressure). |
| Rated Speed | 1800 – 2400 รอบต่อนาที (revolutions per minute) | Optimal speed range for high volumetric efficiency (≥92%) and low operating noise. |
| Minimum Speed | ≥600 rpm | Prevents cavitation (air bubbles in oil) and ensures consistent oil suction; avoid running below this speed for extended periods. |
| Hydraulic Fluid Compatibility | isos vg 32/46/68 mineral-based hydraulic oil | Must meet cleanliness standard Nas 8 or higher (use high-efficiency suction/return line filters to avoid contamination). |
| Operating Temperature Range | -20° C ถึง +80 ° C (-4° F ถึง +176 ° F) | Extreme temperatures (below -20°C or above +80°C) degrade seal performance and oil viscosity, leading to pump failure. |
