V38D12RAX-95 Hydraulic Oil Piston Pump
| Theoretical Displacement | ~38 cm³/rev | Determines maximum flow output (flow = displacement × speed × volumetric efficiency). |
| 最大連続圧力 | 28 MPA (4060 psi) | 安全な長期動作圧力; exceeding this causes premature wear of pistons, valve plates, or seals. |
| ピーク圧力 | 35 MPA (5075 psi) | Short-duration pressure (≤5秒) for emergency heavy loads (例えば, sudden machine jolts); avoid prolonged use. |
| 定格速度 | 1000 – 2500 RPM | 高容量効率のための最適な速度範囲 (≥91%) そして低ノイズ (≤76 dB(a) at 1m distance). |
| 最小速度 | ≥600 rpm | キャビテーションを防ぎます (air bubble formation in oil); running below 600 rpm reduces suction efficiency and causes flow instability. |
| 油圧液互換性 | ISOS VG 32/46/68 mineral-based hydraulic oil | Must meet cleanliness standard NAS 8 または高 (use 10 μm filtration to avoid contamination of precision internal components). |
| 動作温度範囲 | -15°C〜 +80°C (5°F〜 +176°F) | Extreme temperatures (below -15°C or above 80°C) thicken/thin oil, reducing pump efficiency and damaging seals. |
