通常清理气轨气孔的方法是用一根比导轨表面小孔直径小的钢丝,对小孔逐个穿通,这种做法,有时会把杂物捅回导轨内腔,以致开机后这些杂物又重新堵住小孔。这种做法还不宜在实验中进行。为了克服以上缺点,我们设计了一个清理附件。用该附件配在吸尘器上清理气轨效果较好。该附件是用一根直径比导轨侧表面宽度略小的塑料硬管,把它的一端锯一斜口然后烤软压扁成一椭圆形。该斜口表面要与导轨表面密切吻合,不能有漏气现象产生,再把塑料管的另一端用软管接到吸尘器的吸 Usually clean up the air hole method is to use a smaller diameter than the track surface of the small diameter wire, the hole one by one through this practice, sometimes debris will be stabbed back into the guide rail cavity, so that these debris boot again Block the hole. This practice should not be carried out in the experiment. In order to overcome the above shortcomings, we designed a cleaning attachment. With the attachment on the cleaner to clean the airway better. The attachment is made of a plastic tube slightly smaller in width than the rail-side surface, sawing one end of the tube at a bevel and then billet softly flattened into an oval shape. The inclined surface to be closely consistent with the rail surface, can not have leakage phenomenon, and then the other end of the plastic hose connected to the vacuum cleaner suction
