| 摘要 |
The invention is concerned with a procedure for use with a pump (6) for the movement of liquid, powered by an internal combustion engine, which pump is not capable of pumping air (gas) and thereby drawing liquid up into itself at start-up when elevated significantly above the body of liquid from which it is to pump; in which procedure the internal combustion engine also powers a hydraulic pump (3) which in turn drives by hydrostatic transmission an immersed pump (10) which pumps liquid up to the pump (6) during the start-up phase.
