Abstract

PURPOSE:To make the whole of pipelines and column pipe into framing structure and improve the resistance to vibration by a method wherein a barrel tank is divided into a plurality of pipelines and each pipelines and the column pipe are connected by a supporting member. CONSTITUTION:The barrel pipelines 9 are located around the column pipe 5 and are connected to the column pipe 5 at the lowermost parts thereof. Each pipelines and the column pipe are connected by the supporting member 10 at the intermediate part thereof. Water, flowed down through the barrel pipelines 9, is pumped up by an impeller attached to the tip end of a shaft 6 and rises up through the column pipe 5. Whole of the pipelines and the column pipe are made by the framing structure, therefore, the rigidity of the structure is increased and, further, the weight thereof is lightened while the resistance to vibration is improved.

る。A column pipe 5 is inserted into the barrel tank 2, and water flowing down inside the barrel tank is sucked up by the impeller 7 attached to the tip of the shaft 6, and flows into the column pipe. It is designed to rise inside. The column pipe 5 is supported by the barrel tank 2 by a column support 8 having a backlash structure.

震性は問題となる所である。Conventional bit barrel type vertical pumps have the structure described above, so the weight inside the barrel tank is extremely large when water is included, and because it has a cantilevered structure that supports only the barrel flange 3, natural vibrations occur. As the number decreases, earthquake resistance becomes a problem.

〔発明の目的〕[Purpose of the invention]

. In FIG. 2(a) and FIG. 2(b) showing a cross section taken along arrow A-A in FIG. connected to the pipe. Further, in the intermediate portion, each pipe and column pipe are connected by a support member 10. The flow of water is the same as before, except that the downward flow in the barrel tank is changed to the barrel piping 9.
