Abstract
PURPOSE: To equalize driving hours as well as to minimize start and stop frequencies for pumps in such a way that a pump-well water-level meter is provided in a pump-well while at the same time a discharge flow meter is provided on the discharge side of a group of pumps, discharge rate of the pumps is decided according to signals from the both.
CONSTITUTION: A pump-well water-level meter 7 is provided in a pump-well 4 while at the same time a discharge flow meter 8 is provided on the discharge side of a group of pumps 5, signals from the both are input to a computer 9, the pumps 5 are driven so that water-level may be within a certain extent when signals from the both are computed, and with use of the results, the pumps start and stop to meet the pumping conditions selected by incorporated algorithm. Thus, useless starts and stops of the pumps can be eliminated with the possibility of equalization of pump driving hours.
