PARKER柱塞泵的主要特點(diǎn)是:①一定的泵在一定轉(zhuǎn)速下所產(chǎn)生的揚(yáng)程有一限定值。工作點(diǎn)流量和軸功率取決于與泵連接的裝置系統(tǒng)的情況(位差、壓力差和管路損失)。揚(yáng)程隨流量而改變(圖2)。②工作穩(wěn)定,輸送連續(xù),流量和壓力無(wú)脈動(dòng)。③一般無(wú)自吸能力,需要將泵先灌滿液體或?qū)⒐苈烦槌烧婵蘸蟛拍荛_(kāi)始工作。④離心泵在排出管路閥門(mén)關(guān)閉狀態(tài)下啟動(dòng),旋渦泵和軸流泵在閥門(mén)全開(kāi)狀態(tài)下啟動(dòng),以減少啟動(dòng)功率。⑤離心泵適合于用高速電動(dòng)機(jī)和汽輪機(jī)等直接驅(qū)動(dòng),結(jié)構(gòu)簡(jiǎn)單,制造成本低,維修方便。⑥適用性能***,離心泵的流量可以從幾到幾十萬(wàn)米3/時(shí),揚(yáng)程可以從數(shù)米到數(shù)千米;軸流泵一般適用于大流量和低揚(yáng)程(20米以下)。離心泵和軸流泵的效率一般在80%以下,高的可達(dá)90%。
