真(zhen)空(kong)壓力本(ben)身具有清(qing)洗疏通管(guan)(guan)道(dao)(dao)的功(gong)能。為防止可(ke)能發生(sheng)的固(gu)體(ti)(ti)過大導(dao)致管(guan)(guan)道(dao)(dao)阻塞現象，高速真(zhen)空(kong)排水(shui)(shui)(shui)系(xi)統(tong)(tong)(tong)還可(ke)在機組(zu)的入(ru)口處(chu)加裝(zhuang)切(qie)割機，將固(gu)體(ti)(ti)顆粒(li)解(jie)體(ti)(ti)剁(duo)碎，地(di)鐵真(zhen)空(kong)排水(shui)(shui)(shui)，同時保護管(guan)(guan)道(dao)(dao)。真(zhen)空(kong)排水(shui)(shui)(shui)系(xi)統(tong)(tong)(tong)，是(shi)對重力排水(shui)(shui)(shui)系(xi)統(tong)(tong)(tong)的一(yi)(yi)種有益補充，是(shi)有別于重力排水(shui)(shui)(shui)系(xi)統(tong)(tong)(tong)的一(yi)(yi)種新型排水(shui)(shui)(shui)系(xi)統(tong)(tong)(tong)，利用真(zhen)空(kong)設(she)備(bei)，使管(guan)(guan)道(dao)(dao)內產生(sheng)一(yi)(yi)定的真(zhen)空(kong)度，利用空(kong)氣(qi)作為輸送介質，從而實(shi)現污水(shui)(shui)(shui)收集的一(yi)(yi)種排水(shui)(shui)(shui)方(fang)式。采用城(cheng)市排水(shui)(shui)(shui)系(xi)統(tong)(tong)(tong)，在毫無(wu)故障的理想狀況下，同口徑大小的排水(shui)(shui)(shui)管(guan)(guan)道(dao)(dao)一(yi)(yi)般也要(yao)6.5分鐘才能將這些水(shui)(shui)(shui)排走。如果(guo)某一(yi)(yi)座(zuo)城(cheng)市立(li)交橋下積水(shui)(shui)(shui)面積達500平方(fang)米、積水(shui)(shui)(shui)深度達8米，采用排水(shui)(shui)(shui)能力為2立(li)方(fang)米/秒(miao)的真(zhen)空(kong)排水(shui)(shui)(shui)系(xi)統(tong)(tong)(tong)，僅需要(yao)34分鐘即可(ke)將這些水(shui)(shui)(shui)排凈(jing)。

真空壓力本身(shen)具有清洗(xi)疏通管(guan)道的(de)(de)功能(neng)。為(wei)防止可能(neng)發生的(de)(de)固(gu)體(ti)(ti)過大(da)導致管(guan)道阻塞(sai)現(xian)象，高(gao)速真空排(pai)水系統還可在機組的(de)(de)入(ru)口處加裝(zhuang)切割(ge)機，將(jiang)固(gu)體(ti)(ti)顆粒解體(ti)(ti)剁(duo)碎，同時保(bao)護管(guan)道。管(guan)道敷設不需設計坡度、豎向處理容易，可以對污水進行提升(sheng)、施工安(an)裝(zhuang)方便快(kuai)捷(jie)。整個系統密封性好(hao)、無滲漏、無氣味(wei)、無臭味(wei)外逸。埋深淺、管(guan)徑小、無淤泥、運管(guan)費低、投資(zi)小。普遍采用的(de)(de)重力排(pai)水系統大(da)多只(zhi)能(neng)順利通過濃度較低、雜質很(hen)少的(de)(de)液(ye)體(ti)(ti)，一旦泔水、淤泥、塑料袋(dai)、碎石、磚塊等雜物混為(wei)一體(ti)(ti)，極(ji)易堵塞(sai)管(guan)道。
