氣體增壓泵在我們日常生產中非常常見，包括很多成品設備上也配有氣體增壓泵。很多人反應，氣體增壓泵經常性的突然不工作，究其原因很多人認為是活塞片卡住了。

Gas booster pumps are very common in our daily production, including many finished products, and also equipped with a gas booster pump. Many people react, gas booster pump often suddenly do not work, the reason, many people think that the piston chip stuck.

大多數這種現象是因為換氣閥里面的閥芯密封出了問題，大多數生產廠家做的閥芯，放置O型圈的凹槽深淺不一，太淺O型圈暴露在外的量較大，時間長了O型圈容易磨損，一旦O型圈爛掉，閥芯和閥體就出現金屬之間相互直接接觸，這樣就容易被卡住。另外，如果凹槽太深，O型圈裸露出的部位太少，容易出現密封不良，漏氣。根據多年的經驗，O型圈裸露在外的量以O型圈厚度的1/4佳。這個數據一能使密封性能好；并不會損傷O型圈。

Most of this phenomenon is because the spool valve inside the valve seal is out of the question, most manufacturers do, the depth of groove for placing the O ring, O ring is too shallow exposed a large amount, long time O ring to wear, once the O ring rot, spool and body appeared between the metal direct contact with each other, so it is easy to get stuck. In addition, if the groove is too deep, the exposed part of the O ring is too small, easy to seal bad, leak. According to the experience of many years, the amount of O ring exposed outside is 1/4 best with the thickness of O circle. This data will make the sealing performance good and will not damage the O ring.

另外，氣體增壓泵在裝閥體的時候，容易把O型圈割傷，從而影響O型圈的使用壽命，這也是氣體增壓泵出故障的一大原因。

In addition, the gas booster pump in the valve body, it is easy to cut O ring, thus affecting the life of O ring, which is a major reason for the gas booster pump failure.
