氣體增壓泵裝置的氣密性如何檢測
氣體增壓泵裝置的氣密性是保證實驗成功的重要因素之一。Gas booster pump device of air tightness is one of the important factors of the success of the experiment.檢查
氣體增壓泵 http://www.jujiaso.cn/氣密性的方法是：把反應裝置中的導管一端浸入水里，用手掌貼反應器的外壁（或用酒精燈微熱），如果裝置不漏氣，容器里的空氣受熱膨脹，導管口就有氣泡逸出；容器冷卻后，又會有水升到導管內形成一段水柱；若裝置漏氣，則不會有氣泡冒出。就好比自行車車胎，補胎的時候，把充氣的輪胎放到水里，看看那里有氣泡。Check gas booster pump air tightness of the method is: the reaction mechanism of the catheter end into the water, the walls of the reactor with the palm of your hand (or slight fever with alcohol lamp), if the device does not leak, the air inside the container, thermal expansion, catheter mouth there are air bubbles escape; Container after cooling, the water would have to intraductal form a water column; If device air, there would be no bubbles. Like bicycle tires, tire repair, the inflatable tires into the water, see there are air bubbles.還有一種方法，在待檢驗物體表面涂上肥皂水，看是否產生氣泡。Another way, in testing the surface coated with soap and water, look to whether have bubbles.
