气体增压泵装置的气密性如何检测

气体增压泵装置的气密性是保证实验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.检查气体增压泵 http://www.xinmingte.com/气密性的方法是：把反应装置中的导管一端浸入水里，用手掌贴反应器的外壁（或用酒精灯微热），如果装置不漏气，容器里的空气受热膨胀，导管口就有气泡逸出；容器冷却后，又会有水升到导管内形成一段水柱；若装置漏气，则不会有气泡冒出。就好比自行车车胎，补胎的时候，把充气的轮胎放到水里，看看那里有气泡。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.还有一种方法，在待检验物体表面涂上肥皂水，看是否产生气泡。Another way, in testing the surface coated with soap and water, look to whether have bubbles.
