產(chǎn)品詳情
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,在這一過(guò)程中,葉輪中的液體繞流葉片
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。
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
這時(shí),葉輪進(jìn)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(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葉片泵以其結(jié)構(gòu)簡(jiǎn)單、使用維修方便
效率較高而成為農(nóng)業(yè)上應(yīng)用廣泛一種水泵
但也因提不上水而令人倍感煩惱。
