V38D12RAX-95 Hydraulic Oil Piston Pump
| Theoretical Displacement | ~38 cm³/rev | Determines maximum flow output (flow = displacement × speed × volumetric efficiency). |
| Maximum Continuous Pressure | 28 الآلام والكروب الذهنية (4060 PSI) | Safe long-term operating pressure; exceeding this causes premature wear of pistons, valve plates, or seals. |
| ضغط الذروة | 35 الآلام والكروب الذهنية (5075 PSI) | Short-duration pressure (≤5 seconds) for emergency heavy loads (e.g., sudden machine jolts); avoid prolonged use. |
| Rated Speed | 1000 – 2500 دورة في الدقيقة | Optimal speed range for high volumetric efficiency (≥91%) and low noise (≤76 dB(أ) 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 (use 10 μm filtration to avoid contamination of precision internal components). |
| Operating Temperature Range | -15° C إلى +80 درجة مئوية (5°F to +176°F) | Extreme temperatures (below -15°C or above 80°C) thicken/thin oil, reducing pump efficiency and damaging seals. |
