PROBLEM TO BE SOLVED: To provide a method for transferring liquid to a high ground without using a pump although a force-feeding method by means of the pump is a main stream with regard to liquid transfer.SOLUTION: A form of embodiment of this invention is illustrated based on a figure. A drawing of Fig.1 is the total image figure of liquid transfer. Liquid is entered into a liquid tank. On the first stage, a check valve 1 is attached to the lower surface side of a liquid-lifting pipe of which the lower surface is opened and the liquid-lifting pipe is erected in the water. A suction pump 2 and an open valve 3 are attached to a tip part of the liquid-lifting pipe. On the second stage, the liquid-lifting pipe is caused to stand up from amidst the upper part of a precedent stage of liquid-lifting pipe. On a lower part of the liquid-lifting pipe, a check valve 4 is attached and, on an upper part thereof, a suction pressure-charging pump 5 and an open valve 6 are attached. On and after the third stage, the liquid-lifting pipe, a check valve 7, a suction pressure-charging pump 8 and an open valve 9 are successively attached likewise.SELECTED DRAWING: Figure 1 |
