【発明の詳細な説明】 〔産業上の利用分野〕 本発明はポンプ用外付け自吸タンクに関し、特に自給
式ポンプ以外のポンプに外付けで自給機能を追加するタ
ンクに関する。Description: BACKGROUND OF THE INVENTION The present invention relates to an external self-priming tank for a pump, and more particularly to an externally-added self-priming tank for a pump other than a self-priming pump.
従来、ポンプ自身より低い位置の液体を吸い上げるポ
ンプとしては、自給式ポンプがある。Conventionally, there is a self-contained pump as a pump for sucking a liquid at a position lower than the pump itself.
上述した従来の自給式ポンプは、自給タンク部がポン
プと一体となっているため、自給能力を変更することが
できないという欠点がある。The conventional self-contained pump described above has a disadvantage that the self-supply capacity cannot be changed because the self-contained tank unit is integrated with the pump.
また、自給式ポンプ以外のポンプでは、ポンプ自身よ
り低い位置の液体を吸い上げることができない。Further, pumps other than the self-contained pump cannot suck liquid at a position lower than the pump itself.
本発明の目的は、自給式ポンプ以外のポンプに連結す

とにある。An object of the present invention is to connect a pump other than a self-contained pump, thereby making it possible to add self-sufficiency without any modification to the pump itself, and to provide a liquid at a lower position than the pump itself such as an underground tank. It is an object of the present invention to provide an external self-priming tank for a pump that can easily suck up water.

しい。A feature of the present invention is that in an external self-priming tank for a pump that sucks up a liquid at a position lower than the pump itself, a self-priming tank sealed with an upper plate provided with a priming port, and one end of the tank is immersed in the liquid. A suction pipe which is inserted into the self-priming tank at the other end and is set up to be slightly below the upper plate, a pump inflow pipe connected to the pump and extending from a lower part of the self-priming tank; An external self-priming tank for a pump, comprising: a flow shield plate that hangs down from a plate and is immersed in the liquid of the self-priming tank. In addition, it is preferable that another self-priming plate be provided that extends horizontally into the liquid from the inner wall of the self-priming tank above the inlet of the pump inflow pipe in the self-priming tank.

The figure is a longitudinal sectional view of one embodiment of the present invention. Self-priming tank 1
A suction pipe 2 is set up slightly below the upper plate 3 and installed therein.
Is attached. A pump inflow pipe 6 is attached below the self-priming tank 1 and is connected to a pump 7.

る。Next, the operation will be described. When a liquid is put into the self-priming tank 1 from the priming port 5 and the pump 7 is operated, the liquid in the self-priming tank 1 is sucked to the pump side through the pump inflow pipe 6. As the liquid in the self-priming tank 1 decreases, the degree of internal vacuum in the self-priming tank 1 increases, and the reduced amount of liquid is sucked into the self-supply tank 1 from the suction pipe 2. The millet or the like sucked up at the same time as the liquid is separated from the liquid by the flow blocking plate 4 and becomes difficult to be sucked into the pump 7.

図に示した第１の実施例に分離板８が追加されている。
この実施例では、遮流板４と分離板８の２重効果により
特にアワの多い液体を吸い上げるのに有利である。FIG. 2 is a longitudinal sectional view of another embodiment of the present invention. First
A separating plate 8 is added to the first embodiment shown in FIG.
In this embodiment, the double effect of the flow blocking plate 4 and the separation plate 8 is particularly advantageous for sucking up a liquid with a lot of bubbles.

る効果がある。As described above, the present invention can add a self-priming capability by connecting to a pump other than the self-priming pump, and can suck a liquid at a position lower than the pump itself, such as an underground tank. There is an effect that can be easily done.
また、自吸式ポンプでは不可能な低い位置の液体を吸
い上げるような大きな自吸能力を、自吸タンクを大きく
することによって比較的容易に実現できる。In addition, a large self-priming capability that can pump a liquid at a low position, which is impossible with a self-priming pump, can be relatively easily realized by enlarging the self-priming tank.
