Kodi vacuum emulsifier yocheperako ndi yotani?

1. Nthawi zambiri pamakhala njira ziwiri zodziwira digiri ya vacuum, imodzi ndiyo kugwiritsa ntchito kupanikizika kotheratu (ie: digirii ya vacuum kwathunthu) kuti izindikire, ndipo ina ndiyo kugwiritsa ntchito mphamvu yachibale (ie: digiri ya vacuum) kuti adziwe.
2. Zomwe zimatchedwa "kupanikizika kwathunthu" zikutanthauza kuti pampu yotsekemera imagwirizanitsidwa ndi chidebe chodziwika. Pambuyo pa nthawi yokwanira yopopera mosalekeza, kupanikizika mu chidebe sikupitirirabe ndikusunga mtengo wina. Panthawiyi, mphamvu ya gasi mu chidebe ndi mtengo wathunthu wa mpope. kupanikizika. Ngati mumtsuko mulibe mpweya, ndiye kuti kupanikizika kotheratu ndi zero, komwe ndi chikhalidwe cha vacuum. M'malo mwake, kukakamiza kwathunthu kwa pampu ya vacuum kuli pakati pa 0 ndi 101.325KPa. Kupanikizika kotheratu kumafunika kuyezedwa ndi chida champhamvu kwambiri. Pa 20 ° C ndi kutalika = 0, mtengo woyamba wa chida ndi 101.325KPa. Mwachidule, kuthamanga kwa mpweya komwe kumadziwika ndi "theoretical vacuum" monga momwe amatchulidwira kumatchedwa: "pressure absolute" kapena "absolute vacuum".
3. "Vacuum yachibale" imatanthawuza kusiyana pakati pa kupanikizika kwa chinthu choyezedwa ndi mpweya wa mumlengalenga wa malo oyezera. Kuyezedwa ndi vacuum gauge wamba. Popanda vacuum, mtengo woyamba wa tebulo ndi 0. Poyesa vacuum, mtengo wake umakhala pakati pa 0 ndi -101.325KPa (nthawi zambiri amawonetsedwa ngati nambala yolakwika). Mwachitsanzo, ngati muyeso woyezera ndi -30KPa, zikutanthauza kuti mpope ukhoza kuponyedwa kumalo opanda mpweya omwe ndi 30KPa otsika kuposa mphamvu ya mumlengalenga pamalo oyezera. Pampu yomweyi ikayesedwa m'malo osiyanasiyana, kuchuluka kwake kwamphamvu kumatha kukhala kosiyana, chifukwa kupanikizika kwamlengalenga kwa malo osiyanasiyana oyezera kumakhala kosiyana, komwe kumachitika chifukwa cha zolinga zosiyanasiyana monga kutalika ndi kutentha m'malo osiyanasiyana. Mwachidule, kuthamanga kwa mpweya komwe kumadziwika ndi "malo oyezera kuthamanga kwa mpweya" monga momwe zimatchulidwira kumatchedwa: "kupanikizika kwachibale" kapena "vacuum yachibale".
4. Njira yodziwika bwino komanso yodziwika bwino yasayansi pamakampani opanga vacuum yapadziko lonse lapansi ndikugwiritsa ntchito chizindikiro champhamvu chonse; amagwiritsidwanso ntchito kwambiri chifukwa cha njira yosavuta yoyezera vacuum wachibale, zida zoyezera zofala kwambiri, zosavuta kugula komanso mtengo wotsika mtengo. Zoonadi, ziwirizi ndizosinthana mwamalingaliro. Njira yosinthira ili motere: kuthamanga kwathunthu = kuthamanga kwa mpweya pamalo oyezera - mtengo wathunthu wa kukakamiza kwachibale.
