气体增压泵在我们日常生产中常见，包括很多成品设备上也配有气体增压泵。很多人反应，气体增压泵经常性的突然不工作，究其原因很多人认为是活塞片卡住了。

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.

大多数这种现象是因为换气阀里面的阀芯密封出了问题，大多数生产厂家做的阀芯，放置O型圈的凹槽深浅不一，太浅O型圈暴露在外的量较大，时间长了O型圈容易磨损，一旦O型圈烂掉，阀芯和阀体就出现金属之间相互直接接触，这样就容易被卡住。另外，如果凹槽太深，O型圈裸露出的部位太少，容易出现密封不良，漏气。根据多年的经验，O型圈裸露在外的量以O型圈厚度的1/4佳。这个数据一能使密封性能好；并不会损伤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，气体增压泵在装阀体的时候，容易把O型圈割伤，从而影响O型圈的使用寿命，这也是气体增压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.
