單吸式臥式脫硫循環泵工作原理：

該密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)主(zhu)要(yao)由副葉(xie)(xie)輪（或副葉(xie)(xie)片(pian)）與(yu)停(ting)車密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)（橡(xiang)膠油(you)(you)封(feng)(feng)(feng)(feng)(feng)(feng)）組成。工(gong)(gong)作(zuo)時由于(yu)(yu)副葉(xie)(xie)輪（或副葉(xie)(xie)片(pian)）旋轉(zhuan)(zhuan)產生的(de)(de)(de)離(li)心力(li)使密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)腔(qiang)處于(yu)(yu)負(fu)壓狀態，從(cong)而阻(zu)止(zhi)液(ye)體向外(wai)(wai)泄漏，此時，停(ting)車密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)不起作(zuo)用(yong)(yong)。橡(xiang)膠油(you)(you)封(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)唇(chun)口因(yin)負(fu)壓而松開，與(yu)軸(zhou)套產生一(yi)定間(jian)隙，減小(xiao)其之(zhi)間(jian)的(de)(de)(de)磨損，延長(chang)了使用(yong)(yong)壽命；停(ting)機時，由于(yu)(yu)副葉(xie)(xie)輪（或副葉(xie)(xie)片(pian)）停(ting)止(zhi)旋轉(zhuan)(zhuan)，密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)腔(qiang)由負(fu)壓轉(zhuan)(zhuan)為正壓，停(ting)車密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)開始工(gong)(gong)作(zuo)，橡(xiang)膠油(you)(you)封(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)唇(chun)口在壓力(li)作(zuo)用(yong)(yong)下緊緊包(bao)住軸(zhou)套，從(cong)而達到密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)目(mu)的(de)(de)(de)。若允(yun)許冷(leng)卻(que)(que)水(shui)滲入介(jie)質內(nei)，可(ke)選(xuan)用(yong)(yong)帶(dai)(dai)冷(leng)卻(que)(que)水(shui)K型(xing)動力(li)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)，即可(ke)添加(jia)外(wai)(wai)冷(leng)卻(que)(que)水(shui)裝置，延長(chang)油(you)(you)封(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)使用(yong)(yong)壽命。該密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)油(you)(you)封(feng)(feng)(feng)(feng)(feng)(feng)采(cai)用(yong)(yong)氟橡(xiang)膠制(zhi)成，主(zhu)要(yao)適用(yong)(yong)于(yu)(yu)輸(shu)送含固體顆粒的(de)(de)(de)料漿、含雜質的(de)(de)(de)污水(shui)等腐蝕性介(jie)質（帶(dai)(dai)冷(leng)卻(que)(que)水(shui)K型(xing)動力(li)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)用(yong)(yong)的(de)(de)(de)冷(leng)卻(que)(que)水(shui)為潔凈的(de)(de)(de)自來水(shui)，壓力(li)適宜在0.05Mpa以內(nei)）。
