PVE19RW-Q1830-1-30-CC-11 Variable Displacement Hydraulic Pump
| Theoretical Displacement | ~60 cm³/rev (based on “Q1830” code) | Determines maximum oil flow per shaft rotation (flow = displacement × speed, adjusted for volumetric efficiency). |
| Maximum Continuous Pressure | 30 الآلام والكروب الذهنية (4350 PSI) | Safe long-term operating pressure; avoid exceeding to prevent piston/valve plate wear. |
| ضغط الذروة | 35 الآلام والكروب الذهنية (5075 PSI) | Short-duration pressure only (e.g., lifting heavy loads); prolonged use causes damage. |
| Rated Speed | 1500 – 2400 دورة في الدقيقة | Optimal speed 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 this speed reduces suction efficiency. |
| Hydraulic Fluid Compatibility | ISOS VG 32/46/68 mineral-based hydraulic oil | Must meet cleanliness standard NAS 8 or higher (use 10μm filtration to avoid contamination-related failures). |
| Operating Temperature Range | -20° C إلى +80 درجة مئوية (-4°F to +176°F) | Extreme temperatures degrade seal performance; use oil heaters/coolers if operating outside this range. |
