AT227318 Hydraulic Pump
| 変位 | 12.5 cm³/rev (calibrated to John Deere OEM standards) | Fixed volume of hydraulic oil delivered per shaft rotation—defines flow rate at a given speed (no adjustability, ideal for constant-load tasks). |
| Pressure Ratings | – Continuous Operating Pressure: 16 MPA (160 バー)
– Intermittent Pressure: 20 MPA (200 バー) – ピーク圧力 (≤3 seconds): 24 MPA (240 バー) |
Medium-pressure tolerance for typical agricultural tasks (例えば, lifting plows, operating loaders) without excessive wear. |
| スピード | – 定格速度: 1,800 RPM (matches John Deere tractor PTO speeds)
– 最高速度: 2,500 RPM – 最小速度: 500 RPM |
Compatible with tractor power take-off (PTO) or engine-driven systems; minimum speed prevents cavitation (air bubble formation). |
| 流量 | – で 1,800 RPM: 22.5 l/min (12.5 cm3/回転× 1,800 回転数÷ 1,000)
– で 2,500 RPM: 31.25 l/min |
Linear flow output—critical for consistent actuator speed (例えば, smooth loader lifting/lowering). |
| Efficiency | – Volumetric Efficiency: ≥88% (at rated pressure/speed)
– Mechanical Efficiency: ≥82% – Total Efficiency: ≥72% |
Balances energy use and performance; sufficient for non-high-precision agricultural applications. |
| 重さ | ~7.5 kg | Lightweight for easy installation/retrofit in tractor engine bays or implement mounts. |
