REXROTH離心泵的作用液體從葉輪進口流向出口的過程中，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，這時，葉輪進口處因液體的排出而形成真空或低壓，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葉片泵主要用于由于顆粒太大以至于一般渣漿泵不能輸送的強磨蝕性物料的連續(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葉片泵工作前，先將泵內(nèi)充滿液體，然后啟動離心泵，葉輪快速轉(zhuǎn)動，葉輪的葉片驅(qū)使液體轉(zhuǎn)動，液體轉(zhuǎn)動時依靠慣性向葉輪外緣流去，同時葉輪從吸入室吸進液體。 在這一過程中，力士樂葉片泵的葉輪中的液體繞流葉片，在繞流運動中液體作用一升力于葉片，反過來葉片以一個與此升力大小相等、方向相反的力作用于液體，這個力對液體做功，使液體得到能量而流出葉輪，這時液體的動能與壓能均增大。 REXROTH葉片泵安裝不當(dāng)。兩帶輪中心距太小或兩軸不太平行，傳動帶緊邊安裝到上面，致使包角太小，兩帶輪直徑計算差錯以及聯(lián)軸傳動水泵兩軸偏心距較大等，均會造成水泵轉(zhuǎn)速變化。 上海維特銳在德國與REXROTH合作，可長期穩(wěn)定供應(yīng)力士樂葉片泵，力士樂電磁閥，REXROTH導(dǎo)軌，力士樂柱塞泵等產(chǎn)品 R900533637 PV7-1X/100-118RE07MC7-16 R900533582 PV7-1X/16-30RE01MC0-08
