詳細(xì)介紹
一、特點(diǎn)：涉及NTP同步排吸泵的配套裝置，是在水泵入口處設(shè)置一儲(chǔ)罐，下部引進(jìn)一吸水管，出口與頂部設(shè)置一連通的射引管。其設(shè)計(jì)合理，結(jié)構(gòu)簡(jiǎn)單，使用方便，可避免倒灌式吸水建造費(fèi)用大、維修不便及吸上式底閥易失靈、搶修困難、影響生產(chǎn)之弊端，使水泵性能得*到*全*面發(fā)揮，特別是對(duì)水泵吸程的有*效利用提供了可靠的保障，節(jié)約了土建、維修及使用費(fèi)用及電力，對(duì)于起、停頻繁的水泵機(jī)組尤為有*效。在電子、電力、化工、化肥、冶金、制藥、石油、農(nóng)*藥、油漆、造紙、食品、電鍍、環(huán)保、消防、市政、凈水、工、紡織印染、采掘選礦、民用建筑等行業(yè)中廣泛適用。
