例如，有一台1959年成都生產的ZB 111-65型全油浸組合式旋片式真空泵，benlai，tadexingnenghenhao，bengyinqingcui，zaoshengbuda，shiyanshishiyongbanian，xingnengyizhinengdadaobiaopaiguiding，houyinmouniandongtianguanbengshiweifangqi，kaibengweinengzhubuqidong，zaiturankaibenghou，zhenkongduzaiyeshangbuqu，yinci，qizhiduonianweiyong。weiyanjiuzhenkongbengweixiujishu，zuozheyuxiubengduoniandewuyougenlaoshifuyiqiduitajinxingjianxiu。dajiahuiyi，dangshigaibengchuxiandongdongdechoudaqisheng，banyidaliangshanwu，bengtifarelihai，tingbuqingyoufoupaiqifamendetiaodongsheng。genjuqingkuangpanduan，shishubuchouqi，choudaqidemaobing。danxuyaojinyibuzhaqingguzhangyuanyin。xianrancaiyongjiandandehuanyoufangfashibunengjiejuewentide，yinweibengshituranchuxianguzhangde，biranyoumouxiebujianzaodaosunhuaisuozhi。dangdakaiyouxiang(即泵外殼)蓋檢查，發現排氣閥門蓋蓋板一螺釘已失，拆下另一螺釘、取出閥門蓋板，發現兩級排氣孔內的彈子均已飛走，蓋板上已被彈子打出很深的凹坑，即將打穿。
是否就是因為彈子飛走後使泵產生不抽氣的毛病呢?
