離心泵的工作原理,離心泵的結(jié)構(gòu)特點(diǎn)一、離心泵的結(jié)構(gòu)特點(diǎn)離心泵的結(jié)構(gòu)特點(diǎn)為：在一個(gè)蝸殼形的泵殼內(nèi)，安裝了一個(gè)可以快速旋轉(zhuǎn)的葉輪，在葉輪上有2～8片葉片。泵殼上有兩個(gè)接口，通向葉輪中心的是進(jìn)口，與吸人管路相接；在泵殼的切線方同的為出口，與排出管路相連接，如圖1-12所示。離心泵的主要工作部件是葉輪。其次是吸液室、泵體（泵殼）、泵蓋、軸封裝置（凄《及填料壓蓋或機(jī)械密封）、軸向力平衡裝置、軸承、聯(lián)軸器、托架、壓出室等。當(dāng)葉輪蓬i時(shí)，液體就能連續(xù)不斷地從吸入口吸人，從排出口排出，并使液體產(chǎn)生壓力而排送到高處：離心泵的結(jié)構(gòu)及組成常用離心泵類產(chǎn)品有如下：IS單級(jí)單吸離心泵ISG型立式單級(jí)管道離心泵ISW型直聯(lián)式單級(jí)臥式離心泵QDL不銹鋼高揚(yáng)程多級(jí)離心泵IH型化工**不銹鋼離心泵IHF耐酸襯氟化工離心泵二、離心泵的工作原理圖1-13所示為離心泵的工作原理示意圖。圖1-14所示為用雨天雨傘旋轉(zhuǎn)甩出傘面上的水來演示離心泵的工作原理。在啟動(dòng)前，要先使液體從漏斗將泵殼與吸入管路內(nèi)灌滿。當(dāng)葉輪飛快旋轉(zhuǎn)時(shí)，葉輪內(nèi)的液體在葉輪內(nèi)葉片的推動(dòng)下也跟著旋轉(zhuǎn)起來，從而使液體獲得了離心力，并沿著葉片流道從葉輪的中心往外運(yùn)動(dòng)。</p><p>
