簡要描述:德國Rexroth力士樂齒輪泵工作原理圖齒輪泵格 力士樂齒輪泵工作原理很簡單,就是個(gè)主動(dòng)輪個(gè)從動(dòng)輪,兩個(gè)齒輪參數(shù)相同,在個(gè)泵體內(nèi)做旋轉(zhuǎn)運(yùn)動(dòng)。在這個(gè)殼體內(nèi)部形成類似個(gè)“8“字形的工作區(qū),齒輪的外徑和兩側(cè)都與殼體緊密配合,傳送介質(zhì)從進(jìn)油口進(jìn)入,隨著齒輪的旋轉(zhuǎn)沿殼體運(yùn)動(dòng),Z后從出油口排出

力士樂齒輪泵也叫正排量裝置,即像個(gè)缸筒內(nèi)的活塞,當(dāng)個(gè)齒進(jìn)入另個(gè)齒的流體空間時(shí),液體就被機(jī)械性地?cái)D排出來。因?yàn)橐后w是不可壓縮的,所以液體和齒就不能在同時(shí)間占據(jù)同空間,這樣,液體就被排除了。由于齒的不斷嚙合,這現(xiàn)象就連續(xù)在發(fā)生,因而也就在泵的出口提供了個(gè)連續(xù)排除量,泵每轉(zhuǎn)轉(zhuǎn),排出的量是樣的。隨著驅(qū)動(dòng)軸的不間斷地旋轉(zhuǎn),泵也就不間斷地排出流體。泵的流量直接與泵的轉(zhuǎn)速有關(guān)。實(shí)際上,在泵內(nèi)有很少量的流體損失,這使泵的運(yùn)行效率不能達(dá)到100%,因?yàn)檫@些流體被用來潤滑軸承及齒輪兩側(cè),而泵體也絕不可能無間隙配合,故不能使流體100%地從出口排出,所以少量的流體損失是必然的。然而泵還是可以良地運(yùn)行,對大多數(shù)擠出物料來說,仍可以達(dá)到93%~98%的效率。齒輪泵工作原理很簡單,就是個(gè)主動(dòng)輪個(gè)從動(dòng)輪,兩個(gè)齒輪參數(shù)相同,在個(gè)泵體內(nèi)做旋轉(zhuǎn)運(yùn)動(dòng)。在這個(gè)殼體內(nèi)部形成類似個(gè)“8”字形的工作區(qū),齒輪的外徑和兩側(cè)都與殼體緊密配合,傳送介質(zhì)從進(jìn)油口進(jìn)入,隨著齒輪的旋轉(zhuǎn)沿殼體運(yùn)動(dòng),zui后從出油口排出,zui后將介質(zhì)的壓力轉(zhuǎn)化成機(jī)械能進(jìn)行做功
