PURPOSE: A water pumping method in a circulating hydraulic power station is provided to absorb the used amount as moving distance of a reciprocating pump by offsetting the weight of water, and to pump water actively as displacement with pumping loss. CONSTITUTION: A facing rod(1) of an axis of symmetry is formed between an upper tub(21) and a lower tub(9). A reciprocating pump having three chambers and three plates is drawn in both ends of the facing rod. The reciprocating pump and the upper tub are connected to pumping pipes(22). The facing rod is moved down with the weight of water as the height of the pumping pipes by a driving pipe(17) of the reciprocating pump. The water pumping of the reciprocating pump is input with adding loss in absorbing, pumping and the loss from the sectional difference between a fixing pipe(16) and the driving pipe as the moving distance of the reciprocating pump with the displacement per second. The pumping method of the circulating water power plant applies the loss of the pumping water input to be below 20% at the minimum of 10kw from 10m head of water. The water is efficiently used and stored without environmental pollution. |
