容積式泵特點及應用

容積(ji)式(shi)(shi)泵具有(you)的特點(dian)有(you)哪些？容積(ji)式(shi)(shi)泵的適用哪些方面(mian)？

空(kong)積式泵(beng)(beng)(beng)的(de)(de)(de)特點：泵(beng)(beng)(beng)在一(yi)定轉速或往(wang)復(fu)次(ci)數下的(de)(de)(de)流(liu)(liu)量(liang)是一(yi)定的(de)(de)(de)，幾乎不隨壓(ya)力(li)而(er)變；工作點壓(ya)力(li)和(he)軸(zhou)功(gong)率取決于(yu)與泵(beng)(beng)(beng)連(lian)接的(de)(de)(de)裝置系統的(de)(de)(de)情(qing)況(kuang)，因此當(dang)泵(beng)(beng)(beng)在排出管路(lu)不通(tong)的(de)(de)(de)情(qing)況(kuang)下運轉時，其壓(ya)力(li)和(he)軸(zhou)功(gong)率會增大到使泵(beng)(beng)(beng)或原動(dong)(dong)(dong)機(ji)破壞，所以須(xu)設置安(an)(an)全閥來保護泵(beng)(beng)(beng)；往(wang)復(fu)泵(beng)(beng)(beng)的(de)(de)(de)流(liu)(liu)量(liang)和(he)壓(ya)力(li)有較(jiao)(jiao)大脈(mo)動(dong)(dong)(dong)，需要采(cai)取相應的(de)(de)(de)消減脈(mo)動(dong)(dong)(dong)措(cuo)施；回(hui)轉泵(beng)(beng)(beng)一(yi)般無(wu)脈(mo)動(dong)(dong)(dong)或只有小(xiao)(xiao)的(de)(de)(de)脈(mo)動(dong)(dong)(dong)；具有自吸能(neng)力(li)，泵(beng)(beng)(beng)啟動(dong)(dong)(dong)后(hou)即能(neng)抽除管路(lu)中的(de)(de)(de)空(kong)氣吸入液(ye)體；啟動(dong)(dong)(dong)泵(beng)(beng)(beng)時須(xu)將排出管路(lu)閥門(men)打開；往(wang)復(fu)泵(beng)(beng)(beng)是低速機(ji)械，尺寸大，制造和(he)安(an)(an)裝費用也大；回(hui)轉泵(beng)(beng)(beng)轉速較(jiao)(jiao)高；往(wang)復(fu)泵(beng)(beng)(beng)適用于(yu)高壓(ya)力(li)(有高達350兆帕的(de)(de)(de))和(he)小(xiao)(xiao)流(liu)(liu)量(liang)；回(hui)轉泵(beng)(beng)(beng)適用于(yu)中小(xiao)(xiao)流(liu)(liu)量(liang)和(he)較(jiao)(jiao)高壓(ya)力(li)。

往復泵(beng)適宜(yi)(yi)輸(shu)送(song)(song)(song)清潔的(de)液體(ti)或氣液混合(he)物，有的(de)泵(beng)如隔(ge)膜泵(beng)可輸(shu)送(song)(song)(song)泥(ni)漿、污水等，主(zhu)(zhu)要用(yong)于給水、提供高(gao)壓(ya)液源(yuan)和(he)計(ji)量(liang)輸(shu)送(song)(song)(song)等。回(hui)轉泵(beng)適宜(yi)(yi)輸(shu)送(song)(song)(song)有潤(run)滑性的(de)清潔的(de)液體(ti)和(he)液氣混合(he)物，特別是粘度大的(de)液體(ti)，主(zhu)(zhu)要用(yong)于油品(pin)、食(shi)品(pin)液體(ti)的(de)輸(shu)送(song)(song)(song)和(he)液壓(ya)傳動(dong)方面。
