Abstract: A WATER SUPPLY APPARATUS (1) IS CAPABLE OF PERFORMING A BACKUP OPERATION, WITHOUT LOWERING WATER SUPPLY CAPABILITY, WHEN A FAILURE HAS OCCURRED IN ONE CONTROL SUBSTRATE DUE TO SURGE OR NOISE CAUSED BY LIGHTNING OR SENSOR WEAR, BY SWITCHING TO THE OTHER CONTROL SUBSTRATE, AND CAPABLE OF RELIABLY PERFORMING THE BACKUP OPERATION. THE WATER SUPPLY APPARATUS INCLUDES: A PLURALITY OF PUMPS (3); A PLURALITY OF MOTORS (4) CONFIGURED TO DRIVE THE PLURALITY OF PUMPS (3); A PLURALITY OF INVERTERS EACH CONFIGURED FOR VARIABLE ROTATIONAL SPEED CONTROL OF A CORRESPONDING ONE OF THE PLURALITY OF MOTORS (4); AND A FIRST CONTROL BOARD AND A SECOND CONTROL BOARD EACH CONFIGURED TO CONTROL THE PLURALITY OF INVERTERS. WHEN AN ABNORMALITY OCCURS IN THE FIRST CONTROL BOARD, THE SECOND CONTROL BOARD BACKS UP THE FIRST CONTROL BOARD TO THEREBY ALLOW THE WATER SUPPLY APPARATUS TO CONTINUE ITS OPERATIONS. THE FIRST CONTROL BOARD, THE PLURALITY OF INVERTERS, AND THE SECOND CONTROL BOARD ARE CONNECTED IN SERIES BY COMMUNICATION LINES.

Abstract: A water supply apparatus is provided to meet demands for energy saving by controlling the rotational speed of a pump (1), for example, so as to lower the rotational speed in the time zone when water is not used much while avoiding the time zone when water is used in large quantities. The water supply apparatus includes the pump (1) configured to pressurize and deliver water, a frequency converter configured to supply electric power to the pump (1) to operate the pump (1) at a variable speed, and a controller (15) configured to send operating signals to the frequency converter so as to operate the pump (1) either at a first operation or at a second operation with less power consumption than the first operation. The controller (15) is configured to judge whether the operation of the pump (1) should be shifted from the first operation to the second operation based on an operational state of the pump (1).
