Abstract
PURPOSE: To open and close in conformity with the actual characteristic of a variable speed pump by a system wherein an opening and closing device of the bypass passage of a variable speed pump is actuated with a flow signal transmitted from a flow relay detecting only the variable speed pump water flow.
CONSTITUTION: A flow relay 8 is provided, for example, for a variable speed pump 1 discharge pipe in order to detect only the water pumped by the variable speed pump 1, the allowable minimum flow of the variable speed pump 1 being directly detected to actuate the solenoid valve V of the bypass pipe 6. The open and close section of the bypass passage 6 comprising the flow relay 8 and the solenoid valve V is detecting the water flow of the variable speed pump 1 to actuate to open/ close the bypass passage 6 during detecting the allowable minimum flow, which is free from interlocking the other part of the pump system with a signal exchange.
