Uvuni wowumitsa vacuum ndi chipangizo chomwe chimagwiritsidwa ntchito potenthetsa, kuyanika, kapena kuchiza zinthu zomwe zimatentha kwambiri kapena zimatha kuphulika.Itha kupereka mpweya wopanda okosijeni kapena wocheperako kuti mupewe kutulutsa kapena kusintha kwa zinthu.Chipangizochi chagwiritsidwa ntchito kwambiri m'madera ambiri chifukwa cha ntchito zosiyanasiyana, monga chithandizo chamankhwala, kuyesa kwa sayansi, ndi kupanga mafakitale.

1, Kukonzekera musanagwiritse ntchito

(1) Sankhani zida zoyanika zoyenera (chitsanzo, mphamvu, ndi zina zotero) malinga ndi zofunikira zowumitsa;

(2) Chiyikeni pamalo abwino komanso okhazikika;

(3) Lumikizani magetsi, mapaipi otulutsa, ndi doko lotulukira.

2, ntchito yoyambira

(1) Yatsani mphamvu yosungira;

(2) Yang'anani mosamala momwe mphete ya mphira pakhomo ilili, kutseka valavu yotulutsa vacuum, ndikutsegula vacuum leakage valve;

(3) Yatsani pulagi yamagetsi mkati mwa bokosi;

(4) Dinani batani la "Vacuum Extraction", gwirizanitsani payipi yochotsa ku zitsanzo zouma, ndikuyamba ntchito yochotsa vacuum;

(5) Pamene mulingo wofunikira wa vacuum wafika, dinani batani la "Close Vacuum Leakage Valve", kutseka vacuum leakage valve, ndipo gwiritsani ntchito batani la "Heating" kuti musinthe kutentha mkati mwa bokosilo.(Zindikirani: Vavu yotulutsa vacuum iyenera kutsekedwa poyamba ndiyeno kutentha kuyenera kuyatsidwa);

(6) Mukadikirira kuti kuyanika kumalizike, tsekani batani la “vacuum extraction”, tsegulani vacuum exhaust valve, ndikubwezeretsanso mphamvu ya mumlengalenga.

3, Kusamala kuti mugwiritse ntchito

(1) Zidazi ziyenera kugwiritsidwa ntchito pansi pazimene zimakwaniritsa zofunikira za kutentha kwa chilengedwe;

(2) Kuphatikizika kwa payipi ya m'zigawo kuyenera kukhala kolimba ndipo sikuyenera kukhala kutayikira, apo ayi zidzakhudza zotsatira zoyesera;

(3) Musanagwire ntchito, fufuzani ngati mphete ya rabara ya pakhomo ilibe, mwinamwake iyenera kusinthidwa panthawi yake;

(4) Panthawi yotentha, makinawo ayenera kutsekedwa panthawi yake kuti azitha kuziziritsa zipangizo, kuti asawonongeke chifukwa cha kutentha;

(5) Mukatha kugwiritsa ntchito, yeretsani zida ndikudula magetsi munthawi yake.

Mwachidule, kugwiritsa ntchito ng'anjo yowumitsa vacuum molingana ndi njira zolondola zogwirira ntchito kumatha kupititsa patsogolo moyo wautumiki ndi mphamvu ya makinawo, ndikupereka maziko odalirika oyesera pazoyeserera zoyenera zakumunda.
