DIRECT-COUPLED AUTOMATIC WATER SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a direct-coupled automatic water supply device for hardly causing the transfer of the vibration of a pump to a first frame and a pump cover, preventing the resonance of the first frame and the pump cover and achieving quiet operation. SOLUTION: The direct-coupled automatic water supply device 1 has the first frame 3 to be mounted in position. The first frame contains an installed second frame 12 having a smaller shape and the second frame is supported on a bottom plate via a first vibration isolator 17 in a vibration isolating manner. The second frame has an installed pump assembly 30 having a turbine pump 33 for supplying a city water flowing into a suction pipe 31 to a discharge pipe 32 in a pressure intensified state while involving vibration during operation. The pump assembly is supported on the second frame via a second vibration isolator 49 in a vibration isolating manner. The pump assembly and the second frame are covered with the pump cover 91.
