Disclosed is a hybrid pump system for a scrubber of a ship. According to an embodiment of the present invention, the hybrid pump system comprises: a scrubber which cleans exhaust gas discharged from an engine of a ship; a water treatment unit which recovers a cleaning fluid sprayed to the scrubber to remove pollutants; a first pump which introduces seawater into the ship, transfers the seawater to a heat exchanger, and discharges the seawater to the outside of the ship; a second pump which supplies the cleaning fluid to the scrubber, transfers the recovered cleaning fluid to the heat exchanger side through the water treatment unit, and resupplies the cleaning fluid cooled by the heat exchanger to the scrubber side; a preliminary pump mounted on the same pipe line as that of the first pump and the second pump to perform the role of the first pump or the role of the second pump by a control signal of the control unit; and the control unit which stops, when one of the first pump and the second pump makes a malfunction, the operation of the pump, which has made the malfunction, and operates the preliminary pump as the substitute. The hybrid pump system for the scrubber of the ship includes a configuration to more effectively use the pumps.

    선박용 스크러버를 위한 하이브리드 펌프시스템이 제시된다. 본 발명의 실시예에 따른 하이브리드 펌프시스템은, 선박의 엔진으로부터 배출된 배기가스에 대한 세정역할을 수행하는 스크러버 및 스크러버에 분사된 세정용 유체를 회수하여 오염물질을 제거하는 수처리부를 포함하는 펌프시스템으로서, 해수를 선박 내부로 유입시켜 열교환기로 전달한 후 선박 외부로 배출시키는 제 1 펌프; 세정용 유체를 스크러버에 공급한 후, 회수된 세정용 유체를 수처리부를 통해 열교환기측에 전달하고, 열교환기에 의해 냉각된 세정용 유체를 스크러버측에 재공급하는 제 2 펌프; 상기 제 1 펌프 및 제 2 펌프와 동일한 배관 라인에 장착되고, 제어부의 제어신호에 의해 제 1 펌프의 역할을 수행하거나 제 2 펌프의 역할을 수행하는 예비 펌프; 및 상기 제 1 펌프 및 제 2 펌프 중 어느 하나의 펌프가 오작동을 일으킬 경우, 오작동 펌프의 작동을 정지한 후 예비 펌프로 대체 작동시키는 제어부;를 포함하는 것을 구성의 요지로 한다.
