HGN桁(heng)车式(shi)(shi)(shi)吸(xi)(xi)(xi)泥(ni)机是沉(chen)淀池(chi)常用(yong)(yong)的(de)排(pai)(pai)泥(ni)装置，广泛适用(yong)(yong)于给水净化厂沉(chen)淀池(chi)和(he)排(pai)(pai)水沉(chen)淀池(chi)，用(yong)(yong)于排(pai)(pai)除沉(chen)积在池(chi)底的(de)污泥(ni)。吸(xi)(xi)(xi)泥(ni)方式(shi)(shi)(shi)根据(ju)用(yong)(yong)户(hu)的(de)要求(qiu)，有虹(hong)吸(xi)(xi)(xi)式(shi)(shi)(shi)和(he)泵(beng)(beng)吸(xi)(xi)(xi)式(shi)(shi)(shi)、泵(beng)(beng)虹(hong)两(liang)吸(xi)(xi)(xi)式(shi)(shi)(shi)等三(san)种可供(gong)选择。虹(hong)吸(xi)(xi)(xi)式(shi)(shi)(shi)采用(yong)(yong)潜水泵(beng)(beng)配(pei)水射(she)器(qi)或(huo)真(zhen)空(kong)泵(beng)(beng)来形成(cheng)虹(hong)吸(xi)(xi)(xi)，利用(yong)(yong)沉(chen)淀池(chi)与排(pai)(pai)泥(ni)槽内的(de)液位差排(pai)(pai)泥(ni)，泵(beng)(beng)吸(xi)(xi)(xi)式(shi)(shi)(shi)直接采用(yong)(yong)泵(beng)(beng)抽取沉(chen)淀污泥(ni)。边桁(heng)走边吸(xi)(xi)(xi)泥(ni)，然后将(jiang)污泥(ni)排(pai)(pai)出池(chi)外。
