PURPOSE: A submersible pump having a vibration sensor is provided to detect the fault of a rotating shaft in real time by attaching the vibration sensor to the submersible pump. CONSTITUTION: A submersible pump(10) includes a driving motor(70). When power is applied to the submersible pump(10) through a power cable(80), the driving motor(70) is driven so that a propeller(90) coupled to a rotating shaft(20) is rotated, thereby pumping water to the outside. Plural vibration sensors(40) are attached to the submersible pump(10) so as to detect vibration of the rotating shaft(20). The vibration sensors(40) detect horizontal and vertical vibration of the rotating shaft(20) in real time. The vibration sensors(40) are attached to a connection box(50) surrounding a bearing(30) of the rotating shaft(20), and a bearing housing(60) surrounding a bearing(30').
