水壓沖擊器與液動沖擊器的差(cha)異 ：

水(shui)(shui)壓(ya)(ya)沖(chong)擊(ji)器(qi)(qi)首要用于(yu)(yu)采礦業(ye)，而液(ye)動(dong)沖(chong)擊(ji)器(qi)(qi)首要用于(yu)(yu)地質(zhi)鉆探。水(shui)(shui)壓(ya)(ya)沖(chong)擊(ji)器(qi)(qi)可(ke)以鉆向(xiang)上孔(kong)、向(xiang)下孔(kong)等(deng)各(ge)個(ge)方向(xiang)孔(kong)，而液(ye)動(dong)沖(chong)擊(ji)器(qi)(qi)一般只能(neng)鉆向(xiang)下孔(kong)。水(shui)(shui)壓(ya)(ya)沖(chong)擊(ji)器(qi)(qi)壓(ya)(ya)力很(hen)高，高達l8～20MPa，而液(ye)動(dong)錘(chui)作業(ye)壓(ya)(ya)力很(hen)低，一般為0.5～4 MPa。  水(shui)(shui)壓(ya)(ya)沖(chong)擊(ji)器(qi)(qi)的鑿速很(hen)高，而液(ye)動(dong)沖(chong)擊(ji)器(qi)(qi)鑿速很(hen)低，可(ke)以相差十倍或十幾倍。水(shui)(shui)壓(ya)(ya)沖(chong)擊(ji)器(qi)(qi)能(neng)量利(li)用率高于(yu)(yu)液(ye)動(dong)沖(chong)擊(ji)器(qi)(qi)，達到(dao)了一般重型液(ye)壓(ya)(ya)鑿巖機的水(shui)(shui)平，而液(ye)動(dong)沖(chong)擊(ji)器(qi)(qi)能(neng)量利(li)用率一般不超(chao)過30％。 

水壓(ya)(ya)沖(chong)擊(ji)(ji)器首(shou)要依(yi)托水的(de)靜(jing)壓(ya)(ya)力推動活塞做(zuo)功(gong)，故稱為水壓(ya)(ya)沖(chong)擊(ji)(ji)器較為穩妥(tuo)，而(er)現在有人(ren)稱之為水力沖(chong)擊(ji)(ji)器，易和首(shou)要依(yi)托動壓(ya)(ya)力做(zuo)功(gong)的(de)液(ye)動沖(chong)擊(ji)(ji)器概(gai)念相(xiang)混，也有人(ren)稱之為液(ye)壓(ya)(ya)沖(chong)擊(ji)(ji)器，則易和以油為介質的(de)液(ye)壓(ya)(ya)沖(chong)擊(ji)(ji)器概(gai)念相(xiang)混。 

水壓沖擊(ji)器的介質為水，且要濾去雜質，而液動沖擊(ji)器介質可以是(shi)水，也可以是(shi)泥漿(jiang)。 

水壓沖(chong)擊(ji)(ji)器結構與作業原理比較簡單，即由滑閥控制活(huo)塞作往復運(yun)動，而液動沖(chong)擊(ji)(ji)器則有(you)正作用、反作用、雙作用、射(she)(she)流式、射(she)(she)吸式等多種類型。

水(shui)(shui)(shui)壓沖擊(ji)器與液動(dong)沖擊(ji)器的相同點(dian)：都(dou)(dou)是置于孔底，潛孔鑿(zao)(zao)巖(yan)(yan)（DTH或(huo)ITH）都(dou)(dou)可(ke)以(yi)以(yi)水(shui)(shui)(shui)為介質；都(dou)(dou)運(yun)用(yong)開路壓力水(shui)(shui)(shui)，即廢水(shui)(shui)(shui)（低壓水(shui)(shui)(shui)）排(pai)出，水(shui)(shui)(shui)壓沖擊(ji)器在地下礦(kuang)的使用(yong)中，廢水(shui)(shui)(shui)沖刷巖(yan)(yan)渣后排(pai)到礦(kuang)山(shan)集水(shui)(shui)(shui)池，沉淀后通過井(jing)下配(pei)流系統泵(beng)回，再輸送到鑿(zao)(zao)巖(yan)(yan)現場。在用(yong)水(shui)(shui)(shui)不方便的當地可(ke)運(yun)用(yong)移動(dong)式(shi)再循(xun)環系統。

液壓(ya)(ya)潛(qian)(qian)(qian)孔沖(chong)(chong)擊(ji)(ji)器(qi)(qi)與(yu)水(shui)(shui)壓(ya)(ya)潛(qian)(qian)(qian)孔沖(chong)(chong)擊(ji)(ji)器(qi)(qi)結(jie)合了頂錘式(shi)液壓(ya)(ya)鑿(zao)(zao)巖機與(yu)氣動潛(qian)(qian)(qian)孔沖(chong)(chong)擊(ji)(ji)器(qi)(qi)的(de)(de)利益，能(neng)(neng)耗小(xiao)，鑿(zao)(zao)速快，炮孔直。水(shui)(shui)壓(ya)(ya)潛(qian)(qian)(qian)孔沖(chong)(chong)擊(ji)(ji)器(qi)(qi)的(de)(de)動力(li)介質與(yu)沖(chong)(chong)刷介質統一， 比(bi)液壓(ya)(ya)潛(qian)(qian)(qian)孔沖(chong)(chong)擊(ji)(ji)器(qi)(qi)更具有發(fa)展(zhan)前途。水(shui)(shui)壓(ya)(ya)潛(qian)(qian)(qian)孔沖(chong)(chong)擊(ji)(ji)器(qi)(qi)首(shou)要(yao)(yao)利用水(shui)(shui)的(de)(de)靜壓(ya)(ya)力(li)，而液動潛(qian)(qian)(qian)孔沖(chong)(chong)擊(ji)(ji)錘首(shou)要(yao)(yao)利用水(shui)(shui)的(de)(de)動壓(ya)(ya)力(li)，這是兩者的(de)(de)首(shou)要(yao)(yao)差(cha)異。我國水(shui)(shui)壓(ya)(ya)潛(qian)(qian)(qian)孔沖(chong)(chong)擊(ji)(ji)器(qi)(qi)的(de)(de)開發(fa)研討方面的(de)(de)報道還很罕見(jian)，我們(men)應當注意研討國外先進經驗，發(fa)展(zhan)水(shui)(shui)壓(ya)(ya)潛(qian)(qian)(qian)孔鑿(zao)(zao)巖技能(neng)(neng)。
