Abstract

본 발명은, 모터의 축의 각 대향단부에 임펠러를 구비하면서, 모터의 주위에 고리형 공간 또는 유로가 형성되어 있는 전주류형 이중흡입펌프를 제공한다. 수직 이중흡입펌프는 외측실린더 및 이 외측실린더에 수용된 모터를 구비한다. 모터는 고정자 및 이 고정자에 회전가능하게 배치된 회전자를 구비한다. 외측실린더는 고정자 주위에 형성되는 유로를 형성한다. 회전자를 지지하는 주축은 거의 수직으로 연장된다. 또한, 펌프는 주축의 상ㆍ하단부에 각각 장착되어 유로와 연통하는 한 쌍의 상부 및 하부임펠러를 포함한다.The present invention provides a mainstream dual suction pump having an impeller at each opposite end of a shaft of a motor, and having an annular space or a flow path formed around the motor. The vertical double suction pump has an outer cylinder and a motor housed in the outer cylinder. The motor has a stator and a rotor rotatably disposed on the stator. The outer cylinder forms a flow path formed around the stator. The main axis supporting the rotor extends almost vertically. In addition, the pump includes a pair of upper and lower impellers respectively mounted at upper and lower ends of the main shaft and communicating with the flow path.
