一、機(ji)械疏通(tong)(tong)(tong)常見(jian)的(de)分為兩種(zhong)：電動下水管(guan)道(dao)疏通(tong)(tong)(tong)機(ji)、首要疏通(tong)(tong)(tong)器和高壓水射流疏通(tong)(tong)(tong)車。
1、電動下(xia)水(shui)(shui)管(guan)道(dao)(dao)疏(shu)通(tong)(tong)機是主要用(yong)于家(jia)庭(ting)下(xia)水(shui)(shui)管(guan)道(dao)(dao)疏(shu)通(tong)(tong)，家(jia)庭(ting)下(xia)水(shui)(shui)管(guan)道(dao)(dao)比較小，長時間使(shi)用(yong)管(guan)道(dao)(dao)內(nei)壁(bi)會有一層(ceng)污垢(gou)，使(shi)管(guan)道(dao)(dao)內(nei)徑(jing)減小，造成管(guan)道(dao)(dao)堵塞，電動下(xia)水(shui)(shui)管(guan)道(dao)(dao)疏(shu)通(tong)(tong)機疏(shu)通(tong)(tong)下(xia)水(shui)(shui)管(guan)道(dao)(dao)的(de)效果(guo)非常(chang)好，方便(bian)快(kuai)捷。電動下(xia)水(shui)(shui)管(guan)道(dao)(dao)疏(shu)通(tong)(tong)機的(de)原理是通(tong)(tong)過旋轉把(ba)有一定(ding)彎度彈(dan)性的(de)鋼(gang)絲轉進堵塞的(de)下(xia)水(shui)(shui)管(guan)道(dao)(dao)里，將各種污垢(gou)攪爛、攪溶，把(ba)堵塞物布條、頭發之類的(de)東西帶出來，達(da)到疏(shu)通(tong)(tong)下(xia)水(shui)(shui)管(guan)道(dao)(dao)的(de)效果(guo)。
2、手(shou)搖疏通器(qi)一(yi)般用于簡單的家(jia)(jia)庭下水(shui)(shui)管(guan)(guan)道(dao)疏通，這種類型(xing)的下水(shui)(shui)管(guan)(guan)道(dao)疏通器(qi)結構(gou)簡單，價格便(bian)宜，一(yi)般家(jia)(jia)里放一(yi)個可(ke)以(yi)隨時疏通下水(shui)(shui)管(guan)(guan)道(dao)。
3、高(gao)壓水(shui)(shui)射流疏通(tong)車是利用高(gao)壓水(shui)(shui)射流（幾百斤(jin)壓力，自由調節）沖洗(xi)疏通(tong)管(guan)道(dao)，將管(guan)道(dao)內壁上的污垢徹底清(qing)除，隨著(zhu)水(shui)(shui)流流出(chu)管(guan)道(dao)。高(gao)壓水(shui)(shui)射流疏通(tong)車是目(mu)前(qian)最先(xian)進的下水(shui)(shui)管(guan)道(dao)疏通(tong)工(gong)具，適(shi)用范圍很廣(guang)泛：家(jia)庭下水(shui)(shui)管(guan)道(dao)疏通(tong)工(gong)業園區下水(shui)(shui)道(dao)疏通(tong)，市政排(pai)水(shui)(shui)管(guan)道(dao)清(qing)洗(xi)疏通(tong)等。
二、化學疏通(tong)下(xia)水管道的方(fang)法(fa)主要包(bao)括管道疏通(tong)劑疏通(tong)下(xia)水管道
市(shi)場上具(ju)有強酸性(xing)或強堿性(xing)兩種類型的(de)管(guan)(guan)道(dao)疏通(tong)劑(ji)，管(guan)(guan)道(dao)疏通(tong)劑(ji)疏通(tong)下水(shui)管(guan)(guan)道(dao)的(de)原理是與堵塞物(wu)(wu)產生化學(xue)反應(ying)，將(jiang)下水(shui)管(guan)(guan)道(dao)內(nei)的(de)堵塞物(wu)(wu)溶解一部分，放如一定(ding)量的(de)水(shui)將(jiang)堵塞物(wu)(wu)沖到主管(guan)(guan)道(dao)。
但是有幾點需要注意(yi)，管道疏通劑(ji)是不(bu)能食(shi)用(yong)的(de)(de)(de)，一定要放在(zai)小孩子不(bu)能拿到(dao)的(de)(de)(de)地方；管道疏通劑(ji)有比(bi)較強的(de)(de)(de)腐蝕性(xing)，直接與手(shou)接觸對皮膚傷害(hai)很大，在(zai)使用(yong)的(de)(de)(de)時候(hou)一定要戴上(shang)手(shou)套。
