PUMP DEVICE, PUMP SYSTEM AND METHOD FOR INSPECTING SLIDE BEARING IN PUMP DEVICE

To provide a pump device capable of wholly inspecting an abrasion state of a slide bearing, a pump system, and a method for inspecting the slide bearing in the pump device.SOLUTION: A vertical shaft pump 1 comprises an impeller, a rotational shaft 3, a slide bearing 4, and a pump casing 10. The vertical shaft pump 1 comprises: a light projecting unit 50 that is mounted with the slide bearing 4 so as to be sandwiched in the axial direction and projects inspection light into a gap S between the slide bearing 4 and the rotational shaft 3; a light receiving unit 60 that receives the inspection light having passed through the gap S; and an optical fiber 61 that transmits information related to the inspection light received by the light receiving unit 60 to the outside of the pump casing 10.SELECTED DRAWING: Figure 2 【課題】滑り軸受の摩耗状態を全体的に点検できるポンプ装置、ポンプシステム及びポンプ装置における滑り軸受の点検方法の提供。【解決手段】立軸ポンプ１は、羽根車と、回転軸３と、滑り軸受４と、ポンプケーシング１０と、を備える立軸ポンプ１であって、滑り軸受４を軸方向で挟んで取り付けられ、滑り軸受４と回転軸３との隙間Ｓに点検光を投光する投光部５０、及び、隙間Ｓを通過した点検光を受光する受光部６０と、受光部６０が受光した点検光に係る情報を、ポンプケーシング１０の外部へ伝送する光ファイバー６１と、を備える。【選択図】図２
