ABNORMALITY DETERMINATION DEVICE OF BOOSTER PUMP, OXYGEN SUPPLY SYSTEM, AND ABNORMALITY DETERMINATION METHOD OF BOOSTER PUMP

To improve operation efficiency by properly determining an abnormality such as a malfunction which occurs at a booster pump for boosting the pressure of liquid oxygen.SOLUTION: A booster pump comprises a power source, a power transmission member for transmitting power, and a booster chamber for boosting the pressure of liquid oxygen. An abnormality determination device detects at least one determination parameter, and determines whether or not an abnormality occurs at the booster pump on the basis of at least one determination parameter. The least one determination parameter includes at least one item among pressure in the booster chamber, discharge pressure from the booster chamber, a consumption energy amount of the power source, a bending load acting on the power transmission member, a compression load acting on the power transmission member, a displacement of the booster chamber, a leakage quantity of the liquid oxygen from the booster chamber, and pulsation generated at the booster pump or piping in which the liquid oxygen flows.SELECTED DRAWING: Figure 2 【課題】液体水素を昇圧するための昇圧ポンプに発生する不具合などの異常を適切に判定することにより、稼働率を向上する。【解決手段】昇圧ポンプは、動力源と、動力を伝達するための動力伝達部材と、液体水素を昇圧するための昇圧室と、を備える。異常判定装置は、少なくとも１つの判定パラメータを検出し、少なくとも１つの判定パラメータに基づいて、昇圧ポンプに異常があるか否かを判定する。少なくとも１つの判定パラメータは、昇圧室内の圧力、昇圧室からの吐出圧力、動力源の消費エネルギ量、動力伝達部材に作用する曲げ荷重、動力伝達部材に作用する圧縮荷重、昇圧室の変位、昇圧室からの液体水素の漏洩量、及び、昇圧ポンプ又は液体水素が流れる配管に生じる振動の少なくとも１つを含む。【選択図】図２
