この発明は下水の水を成る揚程だけ揚水するときなどに
用いられるスパイラルポンプのランナー支持装置の改良
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a runner support device for a spiral pump used when pumping sewage water by a certain pumping height.
通常、この種のスパイラルポンプでは、そのランナーの
主軸はその両端に配置された上部メタルと下部の水中メ
タルによって支持され、且つ従来の構造では上部メタル
を分解、点検のため取外すときはランナーも共に取外す
必要があり、上部メタルの分解、点検に著しい手間を要
した。Normally, in this type of spiral pump, the main shaft of the runner is supported by an upper metal and a lower submersible metal placed at both ends, and in conventional structures, when the upper metal is disassembled or removed for inspection, the runner is also removed. It was necessary to remove it, and it took considerable effort to disassemble and inspect the upper metal.
それ故、この発明の目的はランナーを取外すことな（、
上部メタルのみを取外すことができるスパイラルポンプ
のランナー支持装置を提供することである。Therefore, the purpose of this invention is not to remove the runner (
To provide a runner support device for a spiral pump from which only the upper metal can be removed.
次にこの発明の一実施例を示す図面を参照のもとに説明
する。Next, an embodiment of the present invention will be described with reference to the drawings.
第１図はこのスパイラルポンプの概略を示し、１は駆動

れるようになっている。FIG. 1 shows an outline of this spiral pump. 1 is a drive motor, and the runner 3 of this spiral pump has its main shaft supported by an upper metal 2 and an underwater metal 4, and is decelerated via a coupling 6 or as desired. It is connected via a device to a drive device 1 and is adapted to be rotated thereby.
本発明によるランナー支持装置の特徴は上部メタル２の

主軸の上部が支持されるようになっていることである。The feature of the runner support device according to the present invention is that a support metal 5 is attached under the upper metal 2 with a base plate interposed therebetween, and when the upper metal 2 is removed, the upper part of the runner main shaft is supported by the support metal 5. This is what is happening.

を閉止する支持板１８とカバー１９から成っている。That is, as shown in FIG. 2, the upper part of the main shaft 10 of the runner 3 is supported by an upper metal 2 mounted on a base plate 12 provided on a concrete base 11, and the upper metal is supported by a thrust bearing 13. , radial bearing 14, spacer 15 between these bearings,
and cases 16 and 17 surrounding them, and a support plate 18 and cover 19 that close the ends.

成っている。In the runner support device according to the present invention, a support metal 5 is attached to the lower surface of the base plate 12, that is, the side surface of the base plate on the runner side. It consists of a supporting metal case 22 surrounding the base plate 12 and fixed to the base plate 12.
従って、このスパイラルポンプが通常の状態に在るとき
には、ランナー３およびその主軸１０は下部の水中メタ
ル４と上部メタル２および補助的に支持メタル５によっ
て支持され、作動時にはランナー３０回転により下水面
の水を上水面の水に揚水高さＨだけ揚水する。Therefore, when this spiral pump is in a normal state, the runner 3 and its main shaft 10 are supported by the lower submersible metal 4, the upper metal 2, and auxiliary support metal 5, and during operation, the runner 30 rotates to lower the sewage surface. Water is pumped to the water surface by a pumping height H.
もし上部メタル２を分解、点検もしくは修理などのため
取外す場合には、主軸１０の上部は支持メタル５のみに
よっても支持することができるので、上部メタル２のみ
を取外すことができ、従来のようにランナー３も共に取
外す必要はないことになる。If the upper metal 2 is to be removed for disassembly, inspection, or repair, the upper part of the main shaft 10 can be supported only by the support metal 5, so only the upper metal 2 can be removed, and the There is no need to remove runner 3 as well.
上記のように、本発明によれば、ランナー３を取外すこ

で著しい効果がある。As described above, according to the present invention, only the upper metal can be removed without removing the runner 3, so disassembly of the runner and disassembly and inspection of the upper metal can be performed extremely easily, and maintenance of the spiral pump It has a remarkable effect on.
