Claims (1)
ポンプ１の軸３の軸封装置６を大気圧に比して負
なる吸引側８に装着したポンプ１に於て、ポンプ
１の匡体内に配接された吐出管７の上方に細孔１
０を開孔し、吸引側の端部９と、流体力学的に連
絡させる。斯の如き時、ポンプ１が停止した時、
吐出管内７を下降する空気が、この細孔１０に達
した時ポンプ１の匡体内に噴出して、吸引側の端
部９に達して、吸引管のサイフオン作用を停止せ
しめ、常にポンプ１の匡体内に、呼び水を残留さ
せ、次のポンプの始動時に、順調に自吸作用を行
ふポンプ。 In the pump 1, in which the shaft sealing device 6 of the shaft 3 of the pump 1, which is driven directly or indirectly by the prime mover 2, is mounted on the suction side 8 which is negative compared to atmospheric pressure, A small hole 1 is placed above the discharge pipe 7 in contact with the
0 is drilled and placed in hydrodynamic communication with the end 9 on the suction side. In such a case, when pump 1 stops,
When the air descending inside the discharge pipe 7 reaches this pore 10, it is ejected into the housing of the pump 1 and reaches the end 9 on the suction side, stopping the siphon action of the suction pipe and causing the pump 1 to constantly flow. A pump that allows priming water to remain in the casing and performs self-priming smoothly when the next pump starts.
