不同(tong)的(de)(de)包裝物(wu)對真(zhen)空(kong)(kong)(kong)(kong)(kong)度(du)也有(you)著不同(tong)的(de)(de)要求(qiu),有(you)些對空(kong)(kong)(kong)(kong)(kong)氣要求(qiu)嚴格的(de)(de)貨物(wu),就(jiu)要用(yong)大(da)(da)功(gong)力的(de)(de)抽(chou)(chou)(chou)真(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)抽(chou)(chou)(chou)除空(kong)(kong)(kong)(kong)(kong)氣。但是有(you)客戶反映,本(ben)來(lai)抽(chou)(chou)(chou)真(zhen)空(kong)(kong)(kong)(kong)(kong)力挺大(da)(da)的(de)(de)真(zhen)空(kong)(kong)(kong)(kong)(kong)機,使用(yong)過(guo)一段(duan)時(shi)間就(jiu)打(da)不到原先的(de)(de)真(zhen)空(kong)(kong)(kong)(kong)(kong)度(du)了,這是什么(me)原因造成的(de)(de)以及該怎么(me)處理呢?下面我來(lai)教大(da)(da)家幾招(zhao):
1、可(ke)能的原(yuan)因(yin)是真空(kong)包(bao)裝機的泵(beng)(beng)體長時間沒有換油(you)(you),或(huo)者長期包(bao)裝含(han)有水(shui)分的貨物(wu),導(dao)致少量的水(shui)分進(jin)入(ru)機油(you)(you)中造成污染(ran),這就導(dao)致了真空(kong)泵(beng)(beng)不正(zheng)正(zheng)常(chang)工(gong)作,達(da)不到要求的真空(kong)度。請更換真空(kong)泵(beng)(beng)油(you)(you)。(如進(jin)口泵(beng)(beng)需要找廠家買(mai)專用泵(beng)(beng)油(you)(you),國(guo)產泵(beng)(beng)可(ke)以用殼牌的。)
2、真(zhen)空(kong)包(bao)裝(zhuang)機(ji)的(de)密封(feng)性不(bu)(bu)好,比如單(dan)室的(de)小型真(zhen)空(kong)包(bao)裝(zhuang)設備和(he)外抽式(shi)真(zhen)空(kong)機(ji)都有海綿做的(de)密封(feng)墊(dian),這(zhe)些(xie)零部(bu)件是需要定(ding)期檢查的(de),出現問(wen)題也會達(da)不(bu)(bu)到包(bao)裝(zhuang)物所要求的(de)真(zhen)空(kong)度(du)。請(qing)更換(huan)海綿密封(feng)墊(dian)或(huo)硅膠密封(feng)條。
