氣體增壓泵常見故障分析及處理辦法

氣體增壓泵如果不能正常(chang)工作，有如下幾種(zhong)可能:

驅(qu)動活(huo)塞(sai)密封(feng)伯磨損，導致活(huo)塞(sai)上(shang)側和下側串氣(qi);

Gas booster pump if it does not work, there are several possible:

Sealing job wear of piston driven, causing the piston upper and lower side hernia;

控(kong)制(zhi)閥(fa)損壞，導致換向閥(fa)不能正常工作;

換(huan)向閥太(tai)臟(zang)，或它(ta)的密封件損壞(huai)，導致它(ta)不能動作;

Control valve damage, lead to the valve does not work;

Reversing valve is too dirty, or the seal is damaged, leading to not move;

兩活(huo)塞(sai)連接(jie)處損壞(huai)，開口銷脫落，兩活(huo)塞(sai)桿(gan)錯位，導致活(huo)塞(sai)桿(gan)不能移動(dong);

The two piston pin joint damage, loss, two piston rod dislocation, causes the piston rod can not move;

在工作中有進會出現這種情況:需增壓氣體被斷開，卻開著增壓泵，增壓泵噪聲也很大。此進氣體增壓泵工作頻率很高，壓(ya)力卻無法加上(shang)去(qu)，增(zeng)壓(ya)泵噪聲也(ye)很大(da)。長時間這樣工作，很容易損壞泵。同樣道理(li)，當增(zeng)壓(ya)泵出口壓(ya)力很低時，增(zeng)壓(ya)泵工作頻率會很高，增(zeng)壓(ya)泵也(ye)容易損壞。

In the work with a will appear this kind of circumstance: the need for booster gas is disconnected, but open the booster pump, booster pump noise is also great. The inlet gas booster pump working frequency is high, the pressure is not added, the booster pump noise is also great. Long time like this, it is easy to damage the pump. Similarly, when the pressure pump outlet pressure is very low, the booster pump working frequency will be high, a booster pump is easy to damage.

在實際工作中級連氣體增壓泵出現過這種特殊情況:卸壓(ya)閥(fa)(fa)V5不(bu)(bu)斷卸壓(ya)，增壓(ya)泵1頻率很快，增壓(ya)泵2頻率低，仔細檢(jian)查后(hou)(hou)發(fa)現V5設(she)(she)定值偏小(xiao)，調(diao)高設(she)(she)值后(hou)(hou)，出現可(ke)調(diao)壓(ya)力開關(guan)閥(fa)(fa)V6大量放氣(qi)。后(hou)(hou)來確認是(shi)增壓(ya)泵1有(you)問題。原來該增壓(ya)泵1的控制閥(fa)(fa)V2上(shang)側(ce)與管道2連通，沒有(you)斷開。因(yin)(yin)此增壓(ya)泵1不(bu)(bu)斷增壓(ya)，不(bu)(bu)愛V6控制。換句話(hua)說，該泵與設(she)(she)計圖紙要求型號(hao)一(yi)樣，但是(shi)它(ta)少裝了(le)一(yi)個小(xiao)零件及氣(qi)路客道堵(du)頭，從而導致工作不(bu)(bu)正常。這個零件應該安裝在泵內，因(yin)(yin)此不(bu)(bu)易發(fa)現。為了(le)使該設(she)(she)備能夠正常工作，采取了(le)的方法:將增壓(ya)泵1進(jin)氣(qi)的截止球閥(fa)(fa)進(jin)氣(qi)量關(guan)小(xiao)，從而降低了(le)增壓(ya)泵1的工作頻率，使泵組維持正常工作。徹底解決則是(shi)裝上(shang)該堵(du)頭。

Had this special case in practical work intermediate even gas booster pump: V5 constant pressure relief valve pressure relief, pressure pump 1 frequency quickly, booster pump 2 frequency is low, after careful examination found that V5 setting value is small, increase the set value, the adjustable pressure valve appeared V6 deflation. It was later confirmed the booster pump 1 problems. The booster pump control valve 1 V2 side and pipe 2 connected, no disconnection. Therefore the booster pump 1 continuous pressure, don"t love V6 control. In other words, the pump and the design requirements of the drawings models, but it installed a few small parts and pneumatic gate plug, resulting in not working properly. This part should be installed in the pump, so it is not easy to find. In order to enable the device to work properly, take a method: cut-off valve air intake booster pump 1 inlet off small, thereby reducing the booster pump working frequency 1, the pump to maintain the normal working group. Solve is installed on the plug.

還有一種特(te)殊情況:增壓泵(beng)2突然停(ting)止工作，總壓力也上(shang)不去了(le)。在(zai)現(xian)場檢查，發現(xian)它的換向閥(fa)V3被頂信不能動彈(dan)。于(yu)是關了(le)增壓泵(beng)組的壓縮空氣，卸(xie)下(xia)V3時，發現(xian)V3的閥(fa)心(xin)被一股氣往處彈(dan)出。原(yuan)來導致V3的閥(fa)心(xin)不能運動是因(yin)為該閥(fa)右(you)端(duan)有壓強，沒(mei)有卸(xie)壓。之所以沒(mei)有卸(xie)壓是因(yin)為活塞停(ting)在(zai)了(le)中(zhong)間(jian)位置，沒(mei)有碰開控制閥(fa)V1。導致活塞停(ting)在(zai)中(zhong)間(jian)有三個原(yuan)因(yin):

氣體增壓泵1出現異常造成增壓(ya)泵2進氣口壓(ya)國過大(da);

氣體增壓泵2有兩個(ge)(ge)增壓氣(qi)缸(gang)，工作時是雙向壓縮(suo)，雙向行(xing)程(cheng)都需要(yao)提供(gong)驅動(dong);活(huo)塞(sai)在靜止(zhi)狀態下(xia)啟(qi)動(dong)時靜摩擦(ca)力大。裝回換向閥V3，打開壓縮(suo)空氣(qi)重(zhong)新啟(qi)動(dong)，泵組工作正常解(jie)決這(zhe)種故障還有一(yi)個(ge)(ge)辦法，就是關掉壓縮(suo)空氣(qi)，讓高(gao)壓氣(qi)體出口壓強降(jiang)到(dao)3Mpa左右，再重(zhong)新啟(qi)動(dong)泵組。
