REXROTH葉片泵主要用于由于顆粒太大以至于一般渣漿泵不能輸送的強(qiáng)磨蝕性物料的連續(xù)輸送。適用于挖泥、吸砂礫、疏浚河道、采礦及金屬冶煉爆渣輸送等。 REXROTH葉片泵依靠旋轉(zhuǎn)葉輪對(duì)液體的作用把原動(dòng)機(jī)的機(jī)械能傳遞給液體。由于離心泵的作用液體從葉輪進(jìn)口流向出口的過(guò)程中,其速度能和壓力能都得到增加,被葉輪排出的液體經(jīng)過(guò)壓出室,大部分速度能轉(zhuǎn)換成壓力能,然后沿排出管路輸送出去。 葉輪進(jìn)口處因液體的排出而形成真空或低壓,力士樂(lè)葉片泵的吸水池中的液體在液面壓力(大氣壓)的作用下,被壓入葉輪的進(jìn)口,于是,旋轉(zhuǎn)著的葉輪就連續(xù)不斷地吸入和排出液體。 REXROTH葉片泵工作前,先將泵內(nèi)充滿液體,然后啟動(dòng)離心泵,葉輪快速轉(zhuǎn)動(dòng),葉輪的葉片驅(qū)使液體轉(zhuǎn)動(dòng),液體轉(zhuǎn)動(dòng)時(shí)依靠慣性向葉輪外緣流去,同時(shí)葉輪從吸入室吸進(jìn)液體。 葉輪中的液體繞流葉片,REXROTH葉片泵在繞流運(yùn)動(dòng)中液體作用一升力于葉片,反過(guò)來(lái)葉片以一個(gè)與此升力大小相等、方向相反的力作用于液體,這個(gè)力對(duì)液體做功,使液體得到能量而流出葉輪,這時(shí)液體的動(dòng)能與壓能均增大。 上海維特銳與德國(guó)REXROTH合作多年,上海維特銳在德國(guó)設(shè)立的公司可以持續(xù)穩(wěn)定供應(yīng)力士樂(lè)產(chǎn)品
