调整引导轮泵的流量。

  1. 松开锁紧螺母 (1) 。

  1. 顺时针转动调整螺钉 (2) 将增大泵的输出流量。 逆时针转动调整螺钉 (2) 将减少泵的输出流量。 将调整螺钉 (2) 转动 1/4 圈将改变下述压力时泵的输出流量。

    1. 第一个调节器弹簧的压力范围是 17800 kPa (2600 psi) 到 25700 kPa (3750 psi)。 如果在该压力范围内调整泵的输出流量,输出流量将改变大约 22L/min (5.8 US gpm)。

    1. 第二个调节器弹簧的压力范围是 25700 kPa (3750 psi) 到 34300 kPa (4950 psi)。 如果在该压力范围内调整泵的输出流量,输出流量将改变大约 14L/min3 (.7 US gpm)。

  1. 拧紧锁紧螺母 (1) 至扭矩为 12 ± 3 N·m (9 ± 2 lb ft)。

  1. 调整驱动泵。 使用锁紧螺母 (3) 和调整螺钉 (4) 代替锁紧螺母 (1) 和调整螺钉 (2) 调整驱动泵。 重复步骤 1 至 3。

调整引导轮泵的最大输出流量。

  1. 松开锁紧螺母 (5) 。

  1. 转动调整螺钉 (6) 以便调整最大输出流量。 顺时针转动调整螺钉 (6) 将减小泵的最大输出流量。 逆时针转动调整螺钉 (31) 将增大泵的最大输出流量。 当调整螺钉 (6) 转动 1/4 圈时,流速改变大约 3.6 L/min (1.0 US gpm)。

  1. .拧紧锁紧螺母 (5) 至扭矩为 55 ± 10 N·m (41 ± 7 lb ft)。

  1. 调整驱动泵的最大输出流量。 使用锁紧螺母 (8) 和调整螺钉 (7) 代替锁紧螺母 (5) 和调整螺钉 (6) 。 重复步骤 1 至 3。
