description To provide a fine air bubble generating pump which enables reduction of power consumption of a pump with a simple structure and efficiently causes cavitation effect to generate fine air bubbles.SOLUTION: A fine air bubble generating pump 1 of the invention is provided with: a suction part 4 which suctions water; and a discharge part 5 which discharges water. Further, a passage 7 in which water flows is formed. The suction part 4 has: a reduction part 12 in which a cross section is reduced from the upstream side to the downstream side of the passage 7; an expansion part 13 in which the cross section is expanded from the upstream side to the downstream side; and a narrow passage part 14 formed between the reduction part 12 and the expansion part 13. Thus, the simple structure can further reduce power consumption for increasing a pressure of the liquid to a high pressure and efficiently cause cavitation effect to generate fine air bubbles.SELECTED DRAWING: Figure 1 【課題】簡易な構成でポンプの消費動力を抑制し、効率的にキャビテーション効果を起こして微細気泡を発生させることができる微細気泡生成ポンプを提供する。【解決手段】本発明の微細気泡生成ポンプ1では、水を吸入する吸入部4および水を吐出する吐出部5が設けられ、水が流動する流路7が形成され、吸入部4が、流路7の上流側から下流側に向かって断面積が縮小する縮小部12と、上流側から下流側に向かって断面積が拡大する拡大部13と、縮小部12と拡大部13との間に形成された細流路部14と、を有する構成としている。そのため簡易な構成で、液体を高圧にするための消費動力をより抑制して効率的にキャビテーション効果を起こして微細気泡を発生させることができる。【選択図】図1
