net pump headとは 意味・読み方・使い方

To provide a single suction volute pump with simple constitution, which can be reduced in a requested NPSH (Net Positive Suction Head) to enhance its suction performance.例文帳に追加

要求ＮＰＳＨを小さくし、吸込み性能を向上させ得る簡単な構造の渦巻ポンプ装置を提供する。 - 特許庁

The pressure control method and the pressure control system of the pump contain a computing and estimating means for first acquiring the net generated pressure of the pump which is the difference between the discharge pressure and suction pressure of the pump and indicating the value and the head and flow-rate of the pump, and computing a shared flow rate of each pump with this value and a quadratic approximate expression.例文帳に追加

本発明のポンプの圧力制御方法およびポンプの圧力制御システムは、最初に、ポンプの吐出圧力と、ポンプ吸込み圧力の差であるポンプの正味発生圧力とを求め、この値とポンプの揚程−流量を表す二次近似式より、ポンプ毎の分担流量を演算推定手段を有する。 - 特許庁

To provide an ammonia removal equipment for wastewater achieving the reduction of NPSH (net positive suction head) and the installation height of a diffusion column on the basis of the lowering of the water temperature on the suction side of a treated water pump, low in equipment cost and installation cost and having good maintenance properties.例文帳に追加

処理水ポンプの吸込み側水温の低下に基づき、ＮＰＳＨの低減および放散塔の設置高さの低減を図り、設備費用およびその設置費用が安価で、かつメンテナンス性が良好な排水中のアンモニア除去装置を提供する。 - 特許庁
