当燃油输油泵使用柴油时,燃油输油泵具有以下技术规格:
- 使泵在 2940 rpm 转速下运转。 整个旁通压力应为
716 到 786 kPa (104 到 114 psi) 。 - 使泵在 840 rpm 转速下运转。 在
550 kPa (80 psi) 压力下的流速必须为3.0 L/min (0.8 US gpm) 。 - 使泵在 2940 rpm 转速下运转。 在
650 kPa (94 psi) 压力下的流速必须为4.50 L/min (1.19 US gpm) . - 使泵在120 rpm 转速下运转。 保持进口对空气打开 10 秒钟。 封闭进口。 泵必须能保持
30 kPa (4 psi) 的真空度最少 30 秒钟。 - 使泵在 840 rpm 转速下运转。 保持进口对空气打开 10 秒钟。 封闭进口。 泵必须能保持
45 kPa (7 psi) 的真空度最少 30 秒钟。 - 封闭进口让泵在 120 rpm 转速下运转 30 秒钟。 泵的进口必须具备最小为
60.9 kPa (8.8 psi) 的吸入提升力。 - 使泵在 140 rpm 转速下运转。 在
200 kPa (29 psi) 压力下的流速必须为0.25 L/min (0.07 US gpm) 。
从驱动端观看泵时,泵的旋转方向为顺时针。
