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工作，有如下幾種可能:
驅動活塞密封伯磨損，導致活塞上側和下側串氣;
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;
控制閥損壞，導致換向閥不能正常工作;
換向閥太臟，或它的密封件損壞，導致它不能動作;
Control valve damage, lead to the valve does not work;
Reversing valve is too dirty, or the seal is damaged, leading to not move;
兩活塞連接處損壞，開口銷脫落，兩活塞桿錯位，導致活塞桿不能移動;
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，壓力卻無法加上去，增壓泵噪聲也很大。長時間這樣工作，很容易損壞泵。同樣道理，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。
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:卸壓閥V5不斷卸壓，增壓泵1頻率很快，增壓泵2頻率低，仔細檢查后發現V5設定值偏小，調高設值后，出現可調壓力開關閥V6大量放氣。后來確認是增壓泵1有問題。原來該增壓泵1的控制閥V2上側與管道2連通，沒有斷開。因此增壓泵1不斷增壓，不愛V6控制。換句話說，該泵與設計圖紙要求型號一樣，但是它少裝了一個小零件及氣路客道堵頭，從而導致工作不正常。這個零件應該安裝在泵內，因此不易發現。為了使該設備能夠正常工作，采取了的方法:將增壓泵1進氣的截止球閥進氣量關小，從而降低了增壓泵1的工作頻率，使泵組維持正常工作。徹底解決則是裝上該堵頭。
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.
還有一種特殊情況:增壓泵2突然停止工作，總壓力也上不去了。在現場檢查，發現它的換向閥V3被頂信不能動彈。于是關了增壓泵組的壓縮空氣，卸下V3時，發現V3的閥心被一股氣往處彈出。原來導致V3的閥心不能運動是因為該閥右端有壓強，沒有卸壓。之所以沒有卸壓是因為活塞停在了中間位置，沒有碰開控制閥V1。導致活塞停在中間有三個原因:
氣體增壓泵1出現異常造成增壓泵2進氣口壓國過大;
氣體增壓泵2有兩個增壓氣缸，工作時是雙向壓縮，雙向行程都需要提供驅動;活塞在靜止狀態下啟動時靜摩擦力大。裝回換向閥V3，打開壓縮空氣重新啟動，泵組工作正常解決這種故障還有一個辦法，就是關掉壓縮空氣，讓高壓氣體出口壓強降到3Mpa左右，再重新啟動泵組。
