れにケーシングな固定する工事が繁雑であると共に既設
の竪軸ポンプに実施するためには。In this method, the work of providing a support in the pit and fixing the casing to this is complicated, and it is difficult to implement it on an existing vertical pump.
ヒツト自体な空にしてからでなげればならないという問
題があった。There was a problem in that it had to be emptied of humans before being released.
本考案は、前記従来技術の欠点を解消するために得れた
ものであって、極めて単純な支持装置によってケーシン
グを支持することにより、ケーシングの固有振動数を変
更し、以てポンプの回転に伴う振動との共振會防止する
ことな目的とするものである。The present invention was achieved in order to eliminate the drawbacks of the prior art, and by supporting the casing with an extremely simple support device, the natural frequency of the casing is changed, thereby controlling the rotation of the pump. The purpose is to prevent resonance with accompanying vibrations.
