PURPOSE: A shaft alignment measuring system for a multi-shaft connection type vertical pump is provided to easily check the coaxial alignment of multiple shafts during inspection of a multi-shaft connection type vertical pump. CONSTITUTION: A shaft alignment measuring system for a multi-shaft connection type vertical pump comprises a cylindrical clamp(20), movable jigs(30), a lower support ring(31), a guide rail(21), levelers(32), and distance measuring sensors(33). The cylindrical clamp is fixed to a first shaft(1) on the top of a coupling(10). The movable jigs are coupled to the cylindrical clamp. The lower support ring is connected to the lower parts of the movable jigs in order to support the movable jig at a uniform interval. The guide rail is formed in the cylindrical clamp in order to guide the movement of the movable jigs. The levelers are installed on the top of the movable jigs in order to confirm the horizontality of the jigs. The distance measuring sensors are provided on the bottom of the movable jigs in order to measure changes in distance to a second shaft(2).
