一、正壓式空氣呼吸器充的是什么氣體
空氣呼吸器,顧名思義就是呼吸的是空氣。正壓式空氣呼吸器氣(qi)(qi)(qi)瓶內(nei)充(chong)裝的是被壓(ya)(ya)縮后的空(kong)氣(qi)(qi)(qi),就是我們(men)正(zheng)(zheng)常正(zheng)(zheng)在(zai)呼吸的大氣(qi)(qi)(qi)環(huan)境里的空(kong)氣(qi)(qi)(qi),空(kong)氣(qi)(qi)(qi)是被通過高(gao)壓(ya)(ya)壓(ya)(ya)縮空(kong)氣(qi)(qi)(qi)充(chong)氣(qi)(qi)(qi)機(ji)升壓(ya)(ya)充(chong)裝到氣(qi)(qi)(qi)瓶里的。正(zheng)(zheng)常情況下,正(zheng)(zheng)壓(ya)(ya)式空(kong)氣(qi)(qi)(qi)呼吸器充(chong)的氣(qi)(qi)(qi)都(dou)是無色無味且(qie)沒(mei)有多少水(shui)汽(qi)的,如果(guo)有味道或者不干凈(jing)肯定是不正(zheng)(zheng)常,對人體呼吸道不好,這(zhe)時候我們(men)就需要(yao)檢查氣(qi)(qi)(qi)瓶和(he)空(kong)壓(ya)(ya)機(ji)充(chong)氣(qi)(qi)(qi)問(wen)題。
二、正壓式空氣呼吸器可以充氧氣嗎
正(zheng)壓(ya)式(shi)空(kong)氣(qi)(qi)呼(hu)吸器(qi)必須裝空(kong)氣(qi)(qi),而且是(shi)經(jing)過壓(ya)縮之后的(de)干凈(jing)純(chun)凈(jing)的(de)空(kong)氣(qi)(qi),一般(ban)在(zai)充氣(qi)(qi)的(de)時候會選擇(ze)空(kong)氣(qi)(qi)比較好(hao)的(de)地方(fang)進行充氣(qi)(qi)。
正壓(ya)式(shi)(shi)空氣(qi)(qi)呼(hu)(hu)吸(xi)(xi)器不能裝(zhuang)氧(yang)氣(qi)(qi),裝(zhuang)氧(yang)氣(qi)(qi)有單純的(de)氧(yang)氣(qi)(qi)呼(hu)(hu)吸(xi)(xi)器,所(suo)以(yi)不能用正壓(ya)式(shi)(shi)空氣(qi)(qi)呼(hu)(hu)吸(xi)(xi)器裝(zhuang)氧(yang)氣(qi)(qi)。而且正壓(ya)式(shi)(shi)空氣(qi)(qi)呼(hu)(hu)吸(xi)(xi)器是有壓(ya)力值的(de),如果裝(zhuang)氧(yang)氣(qi)(qi)壓(ya)力值不一樣也不能準確(que)的(de)清楚(chu)里面(mian)的(de)壓(ya)力是多少,容易出現危險,所(suo)以(yi)為了避免危險情(qing)況出現,正壓(ya)式(shi)(shi)空氣(qi)(qi)呼(hu)(hu)吸(xi)(xi)器一定不能裝(zhuang)氧(yang)氣(qi)(qi)。
三、正壓式空氣呼吸器充氣常見問題
1、空(kong)(kong)氣(qi)(qi)(qi)(qi)呼吸器充(chong)氣(qi)(qi)(qi)(qi)泵(beng)(beng)給正壓(ya)(ya)式空(kong)(kong)氣(qi)(qi)(qi)(qi)呼吸器充(chong)氣(qi)(qi)(qi)(qi)時(shi),如果是(shi)(shi)充(chong)氣(qi)(qi)(qi)(qi)泵(beng)(beng)本身的(de)質量問(wen)題或(huo)者故障,那么很可能(neng)(neng)就(jiu)會造(zao)成氣(qi)(qi)(qi)(qi)壓(ya)(ya)達不到(dao)30mpa。因此若是(shi)(shi)發現無法充(chong)到(dao)規定氣(qi)(qi)(qi)(qi)壓(ya)(ya),首先應檢查(cha)空(kong)(kong)氣(qi)(qi)(qi)(qi)呼吸器充(chong)氣(qi)(qi)(qi)(qi)泵(beng)(beng)自身氣(qi)(qi)(qi)(qi)壓(ya)(ya)是(shi)(shi)否能(neng)(neng)達到(dao)規定氣(qi)(qi)(qi)(qi)壓(ya)(ya),具體辦法就(jiu)是(shi)(shi)將(jiang)空(kong)(kong)氣(qi)(qi)(qi)(qi)呼吸器充(chong)氣(qi)(qi)(qi)(qi)泵(beng)(beng)各(ge)個閥門都關閉,然后(hou)開(kai)機進(jin)行加壓(ya)(ya),觀察充(chong)氣(qi)(qi)(qi)(qi)泵(beng)(beng)上(shang)的(de)壓(ya)(ya)力表是(shi)(shi)否能(neng)(neng)達到(dao)額定壓(ya)(ya)力甚至之上(shang)。
2、空氣(qi)(qi)在(zai)壓縮的時候是(shi)(shi)(shi)(shi)吸熱(re)的,也就(jiu)是(shi)(shi)(shi)(shi)說充(chong)氣(qi)(qi)泵沖入氣(qi)(qi)瓶(ping)內的氣(qi)(qi)體是(shi)(shi)(shi)(shi)帶有(you)熱(re)量(liang)的,是(shi)(shi)(shi)(shi)膨脹的,我(wo)們把手放到(dao)剛充(chong)滿氣(qi)(qi)的氣(qi)(qi)瓶(ping)上會感覺到(dao)氣(qi)(qi)瓶(ping)是(shi)(shi)(shi)(shi)熱(re)的,當(dang)過一段時間(jian)氣(qi)(qi)瓶(ping)內氣(qi)(qi)體熱(re)量(liang)散失,空氣(qi)(qi)體積就(jiu)會變小(xiao),從而導致整體氣(qi)(qi)壓小(xiao)于30mpa,這(zhe)是(shi)(shi)(shi)(shi)一種正(zheng)常的現象(xiang),而不是(shi)(shi)(shi)(shi)氣(qi)(qi)瓶(ping)故障(zhang),在(zai)充(chong)氣(qi)(qi)的時候氣(qi)(qi)壓可以稍高于30mpa來保證氣(qi)(qi)體的充(chong)足(zu)。
