加力泵

时下黄河放淤固堤远距离输沙的许多施工中需安装加力泵，而加力泵站内发动机的冷却和泥浆泵填料的冲洗问题，一直难以解决。

At present , much of the construction need to install the pump of thrust augmentation in long-distance transporting the sand of the yellow river silt discharge and dike reinforcement , but it is always difficult to solve the flush problem of engine cooling and pump silt .

克服柱塞式加力燃油泵汽蚀的措施

A methed for overcoming cavitation in plunger afterburning fuel pump

结果表明，燃油系统中加力及泵油部件导致的高压高速航空煤油压强快速变化是造成空蚀的主要原因，空蚀过程中通常还伴有显著的相选择行为及由其引发的镂空效应。

The results showed that pressure changes caused by the afterburning and pumping components in fuel system were the main reason to lead to cavitation erosion . Phase-select and hollow out behaviors had been observed on the eroded surface .
