A method and system for collecting a vibration phase signal of a nuclear reactor cooling pump, falling within the technical field of nuclear power plant security. The system comprises: a vibration probe (11), a vibration signal processor (12), a phase probe (22), a reference pulse signal processor (23) and a phase signal processor (31). The vibration probe (11) is electrically connected to the vibration signal processor (12), the phase probe (22) is electrically connected to the reference pulse signal processor (23), and the vibration signal processor (12) and the reference pulse signal processor (23) are both in a communication connection with the phase signal processor (31). A reference pulse signal is acquired by means of the newly added phase probe (22), and then, the acquired reference pulse signal and an existing vibration signal are calculated by means of the phase signal processor (31) so as to obtain a vibration phase signal of a main shaft of a nuclear reactor cooling pump. In this way, the system for collecting a vibration phase signal of a nuclear reactor cooling pump can monitor the vibration phase signal of the main shaft of the nuclear reactor cooling pump, and can thus analyze a vibration condition of the nuclear reactor cooling pump more comprehensively.
