詳細介紹
REXROTH油泵是液壓系統(tǒng)的動力機構(gòu),它將原動機(電動機、內(nèi)燃機等)的機械能轉(zhuǎn)變?yōu)橐后w的壓力能。
力士樂油泵可以分為容積式和非容積室(蝸輪式)兩種。非容積式有離心泵、軸流泵等,利用高速旋轉(zhuǎn)的葉輪使進口產(chǎn)生真空吸入液體,并在出口連續(xù)輸出壓力液體。這種泵進口與出口相通,效率隨液體粘度增加而降低,并且輸出液體量隨出口壓力升高而顯著減少。
容積式泵是通過一個封閉的空間容積的變化來實現(xiàn)吸油和壓油的。當這個封閉容積由小變大時進行吸油,由大變小時進行壓油。典型的為力士樂柱塞泵,柱塞從缸孔中拉出時吸油,壓進時壓油。這種泵進口與出口是被隔開的,效率取決于隔開吸壓油腔的各對運動零件間的結(jié)構(gòu)工藝間隙及油液的粘度等。粘度越高效率越高,輸油量幾乎保持不變。
REXROTH油泵是一種既輕便又緊湊的泵,提出了一種具有一個由含鋁材料制成的外殼的油泵和設(shè)置在該外殼中的可運動的模制件,其中,該可運動的模制件至少部分地由一種可燒結(jié)的、至少包含一種奧氏體的鐵基合金的材料制成,并且其中由一種可燒結(jié)材料制成的該模制件具有一個至少為該外殼的熱膨脹系數(shù)60%的熱膨脹系數(shù)。
1柱塞泵一般用于機床、冶金、鍛壓、礦山及起重機械的液壓傳動系統(tǒng)中,特別廣泛地應用于大功率的液壓傳動系統(tǒng)中。
2葉片泵一般主要用在礦業(yè),煤炭,冶金,化工,環(huán)保等行業(yè)。一般意義的砂泵更多是指用在環(huán)保,挖沙,河道清淤等行業(yè)較多。這個系列砂泵主要以ES或者G系列的較多。除此之外,叫做砂泵的類型還有很多,石油領(lǐng)域的SB砂泵,礦業(yè)上的PS砂泵系列等等。本文介紹的砂泵主要以通常意義上的ES或G系列的挖沙,環(huán)保行業(yè)的用的砂泵。
3齒輪泵適用于輸送石油、化工、涂料、染料、食品、油脂、醫(yī)藥等行業(yè)中的牛頓液體或非牛頓液體,輸送液體的種類可由輕質(zhì)、揮發(fā)性液體,直至重質(zhì)、粘稠,甚至半固態(tài)液體。
