Abstract
【課題】 複数のポンプユニットを用いなくても冗長性を確保することが可能なポンプユニットを提供する。
【解決手段】 予め設定された単位流量で液体を送る配管に設けられるポンプユニットは、n+1台のポンプ及び定流量弁を具備する。ポンプは、n台を直列に配列して前記液体をそれぞれで昇圧することで前記単位流量を満たすように設定され、n+1台が直列に配列される。定流量弁は、前記n+1台のポンプの下流に設置され、前記流体が前記n+1台のポンプのうちn台のポンプにより昇圧された場合、前記流体に第1の抵抗をかけて前記流体を前記単位流量で送る。また、定流量弁は、前記流体が前記n+1台のポンプにより昇圧された場合、前記流体に前記第1の抵抗よりも大きな第2の抵抗をかけて前記流体を前記単位流量で送る。
【選択図】図1
