空氣增壓泵壓力達不到的原因所在

空氣增壓泵假如不能正常工作,那就要看看下面幾種情況了

1)空氣增壓泵的驅動活塞密封伯磨損,導致活塞上側和下側串氣

2)控制閥破壞,導致換向閥不能正常(chang)工(gong)作

3)換(huan)向閥太臟,或它的(de)密封件損壞(huai),導致它不能(neng)動(dong)作

4)兩(liang)(liang)活(huo)塞(sai)毗連處損壞,開口銷脫落(luo),兩(liang)(liang)活(huo)塞(sai)桿錯位,導(dao)致活(huo)塞(sai)桿不能移動(dong)

5)增壓缸密封(feng)件漏氣.

在工作中有進會出現這種環境:需增壓氣體被斷開,卻開著空氣增壓泵,增壓泵噪聲也很大.此進增壓泵工作頻率很高,壓力卻無法加上去,增壓泵噪聲也很大.長時間如許工作,很輕易損壞泵.同樣原理,當增壓泵出口壓力很低時,增壓泵工作頻率會很高,增壓泵也容易損壞.

在現(xian)實工(gong)作(zuo)中級連增(zeng)(zeng)壓(ya)泵(beng)(beng)出現(xian)過這種(zhong)特別情況:卸壓(ya)閥V5不(bu)停(ting)(ting)卸壓(ya),增(zeng)(zeng)壓(ya)泵(beng)(beng)1頻率(lv)很(hen)快(kuai),增(zeng)(zeng)壓(ya)泵(beng)(beng)2頻率(lv)低(di),細致查抄后發現(xian)V5設(she)定值(zhi)偏小(xiao),調高設(she)值(zhi)后,出現(xian)可調壓(ya)力開(kai)關(guan)閥V6大(da)量(liang)放(fang)氣(qi)(qi).厥后確(que)認是(shi)(shi)增(zeng)(zeng)壓(ya)泵(beng)(beng)1有題目.原(yuan)來(lai)該(gai)(gai)(gai)增(zeng)(zeng)壓(ya)泵(beng)(beng)1的(de)(de)控(kong)制閥V2上側(ce)與(yu)管道2連通(tong),沒有斷開(kai).因(yin)此(ci)增(zeng)(zeng)壓(ya)泵(beng)(beng)1不(bu)斷增(zeng)(zeng)壓(ya),不(bu)受V6控(kong)制.換(huan)句話說,該(gai)(gai)(gai)泵(beng)(beng)與(yu)計劃圖(tu)紙要(yao)求型(xing)號(hao)一(yi)(yi)樣,但是(shi)(shi)它少裝了(le)一(yi)(yi)個小(xiao)零件及氣(qi)(qi)路客道堵(du)頭(tou),從而(er)導(dao)致工(gong)作(zuo)不(bu)正(zheng)(zheng)(zheng)常(chang).這個零件應該(gai)(gai)(gai)安裝在泵(beng)(beng)內,因(yin)此(ci)不(bu)易發現(xian).為了(le)使(shi)該(gai)(gai)(gai)裝備(bei)可以大(da)概正(zheng)(zheng)(zheng)常(chang)工(gong)作(zuo),接(jie)納(na)了(le)的(de)(de)方(fang)法:將增(zeng)(zeng)壓(ya)泵(beng)(beng)1進氣(qi)(qi)的(de)(de)停(ting)(ting)止球閥進宇量(liang)關(guan)小(xiao),從而(er)低(di)落了(le)增(zeng)(zeng)壓(ya)泵(beng)(beng)1的(de)(de)工(gong)作(zuo)頻率(lv),使(shi)泵(beng)(beng)組維持正(zheng)(zheng)(zheng)常(chang)工(gong)作(zuo).徹底辦理則是(shi)(shi)裝上該(gai)(gai)(gai)堵(du)頭(tou).

另(ling)有(you)(you)一種特殊情況:增(zeng)壓(ya)(ya)(ya)泵(beng)忽然制(zhi)止工(gong)作,總壓(ya)(ya)(ya)力也上不(bu)去了.在現(xian)(xian)(xian)場檢(jian)查,發現(xian)(xian)(xian)它的換向(xiang)閥V3被頂(ding)信(xin)不(bu)能動(dong)(dong)彈(dan).于(yu)(yu)是關了增(zeng)壓(ya)(ya)(ya)泵(beng)組(zu)(zu)的壓(ya)(ya)(ya)縮(suo)(suo)空(kong)氣(qi),卸下V3時(shi)(shi),發現(xian)(xian)(xian)V3的閥心被一股(gu)氣(qi)往處彈(dan)出(chu).原來導(dao)致V3的閥心不(bu)能活(huo)(huo)動(dong)(dong)是由于(yu)(yu)該(gai)閥右端有(you)(you)壓(ya)(ya)(ya)強(qiang),沒有(you)(you)卸壓(ya)(ya)(ya).之以是沒有(you)(you)卸壓(ya)(ya)(ya)是因(yin)為活(huo)(huo)塞停(ting)在了中心位置,沒有(you)(you)碰開(kai)控制(zhi)閥V1.導(dao)致活(huo)(huo)塞停(ting)在中間有(you)(you)三個緣故原由:(1)增(zeng)壓(ya)(ya)(ya)泵(beng)1出(chu)現(xian)(xian)(xian)非常造成增(zeng)壓(ya)(ya)(ya)泵(beng)2進氣(qi)口壓(ya)(ya)(ya)國過大(da);(2)氣(qi)體增(zeng)壓(ya)(ya)(ya)泵(beng)有(you)(you)兩個增(zeng)壓(ya)(ya)(ya)氣(qi)缸,工(gong)作時(shi)(shi)是雙(shuang)向(xiang)壓(ya)(ya)(ya)縮(suo)(suo),雙(shuang)向(xiang)行(xing)程都(dou)必要提(ti)供(gong)驅(qu)動(dong)(dong);(3)活(huo)(huo)塞在靜(jing)(jing)止狀態(tai)下啟動(dong)(dong)時(shi)(shi)靜(jing)(jing)摩擦力大(da).裝回換向(xiang)閥V3,打開(kai)壓(ya)(ya)(ya)縮(suo)(suo)空(kong)氣(qi)重新啟動(dong)(dong),泵(beng)組(zu)(zu)工(gong)作正常解(jie)決這種故障還有(you)(you)一個辦法,就是關掉壓(ya)(ya)(ya)縮(suo)(suo)空(kong)氣(qi),讓高壓(ya)(ya)(ya)氣(qi)體出(chu)口壓(ya)(ya)(ya)強(qiang)降到3Mpa左右,再重新啟動(dong)(dong)泵(beng)組(zu)(zu).
