CONTROL DEVICE OF A SINGLE-PHASE AC MOTOR PUMP, CAPABLE OF REDUCING MAINTENANCE COSTS

摘要

PURPOSE: A control device of a single-phase AC motor pump is provided to improve durability and reduce noise by controlling drive and stop motions smoothly through sensing a pressure sensor and electric controlling.;CONSTITUTION: A control device of a single-phase AC motor pump(10) comprises a coupling part(22) corresponding to a pressure switch joining unit(12) and a pressure sensor unit(20). The pressure sensor unit comprises a housing, a pressure sensor(26), and a control board(24). The pressure sensor is installed inside the housing and senses the pump pressure. A control circuit of the control board proportionally controls output of a motor based on analog signals that is increased or decreased by the pressure sensor.;COPYRIGHT KIPO 2012
