KFP2130-KP2107CMMS 油圧パイロットギアポンプ
Theoretical Displacement ~3.0 cm³/rev Low displacement = low flow (ideal for pilot circuits, which require minimal oil volume for control). 最大連続圧力 7 MPa (1015 psi) Pilot systems operate at low pressure; exceeding 7 MPa damages control valves. 定格流量 (で 1500 RPM) ~4.5 L/min (毎分リットル) 次のように計算されます: Displacement × Speed ÷ 1000 (3.0 cm3/回転× 1500 回転数÷ 1000 = 4.5 l/min). 定格速度 1000 – 2000 rpm Optimal speed for stable flow (avoids pressure fluctuations in pilot lines). Minimum Speed ≥500 rpm Prevents flow instability (pilot circuits need consistent oil supply to avoid delayed control responses). Hydraulic Fluid Compatibility ISO VG 32/46 mineral-based hydraulic oil Must meet cleanliness standard NAS 9 または高 (pilot valves have small orifices—contamination causes blockages). Operating Temperature Range -10°C to +70°C (14°F to +158°F) Extreme temperatures degrade NBR seals or thicken oil, slowing control responses.
