V38D12RAX-95 Hydraulic Oil Piston Pump
| Theoretical Displacement | ~38 cm³/rev | Determines maximum flow output (flow = displacement × speed × volumetric efficiency). |
| Maximum Continuous Pressure | 28 MPA (4060 PSI) | Safe long-term operating pressure; exceeding this causes premature wear of pistons, valve plates, or seals. |
| Peak Pressure | 35 MPA (5075 PSI) | Short-duration pressure (≤5วินาที) for emergency heavy loads (e.g., sudden machine jolts); avoid prolonged use. |
| Rated Speed | 1000 – 2500 รอบต่อนาที | Optimal speed range for high volumetric efficiency (≥91%) and low noise (≤76 dB(อัน) at 1m distance). |
| Minimum Speed | ≥600 rpm | Prevents cavitation (air bubble formation in oil); running below 600 rpm reduces suction efficiency and causes flow instability. |
| Hydraulic Fluid Compatibility | isos vg 32/46/68 mineral-based hydraulic oil | Must meet cleanliness standard Nas 8 or higher (ใช้ 10 μm filtration to avoid contamination of precision internal components). |
| Operating Temperature Range | -15° C ถึง +80 ° C (5° F ถึง +176 ° F) | Extreme temperatures (below -15°C or above 80°C) thicken/thin oil, reducing pump efficiency and damaging seals. |
