Mapampu ofalitsa ndi ofunikira kwambiri m'mafakitale ambiri, makamaka omwe amafunikira vacuum yambiri. Mapampu awa atsimikizira kuti amagwira ntchito bwino komanso ndi odalirika mobwerezabwereza. Lero tifufuza mozama momwe pampu yofalitsa imagwirira ntchito ndikuwona momwe imagwirira ntchito popanga vacuum yabwino kwambiri.
Mapampu ofalitsa madzi amadziwika kuti amatha kupeza mwachangu ndikusunga kuchuluka kwa vacuum m'malo ambiri. Amagwiritsidwa ntchito kwambiri popanga zinthu monga semiconductor, vacuum coating, ndi zipinda zoyeserera malo. Koma kodi amagwira ntchito bwanji?
Mfundo yogwirira ntchito ya pampu yofalitsa imayang'ana kwambiri njira yofalitsa mamolekyu. Mwachidule, kufalitsa kumaphatikizapo kuyenda kwa mamolekyu kuchokera kudera lomwe lili ndi kuchuluka kwakukulu kupita kudera lomwe lili ndi kuchuluka kochepa. Pa mapampu ofalitsa, njirayi imachitika pang'onopang'ono.
1. Kutulutsa nthunzi: Pampu yofalitsa imadzazidwa ndi madzi oyenera opompedwa, nthawi zambiri mafuta otsika nthunzi monga silicone kapena polyphenylene ether. Pogwiritsa ntchito ma coil amagetsi kapena zotenthetsera zakunja kuti madziwo atenthe, zomwe zimapangitsa kuti asungunuke ndikupanga nthunzi yothamanga kwambiri.
2. Mphuno: Pamwamba pa pompo yofalitsira mpweya, pali cholumikizira mpweya kapena chopopera mpweya. Mphuno iyi yapangidwa kuti ipange mpweya wa nthunzi wothamanga kwambiri, womwe ndi wofunikira kwambiri pakugwira ntchito kwa pompo.
3. Kugwedezeka kwa jet: Jet ya supersonic ya nthunzi imatsikira pansi pa pampu. Ikagundana ndi mamolekyu a mpweya wozizira mu pampu, amakankhidwira pakati, zomwe zimapangitsa kuti pakhale malo okhala ndi vacuum yambiri.
4. Malo Ogwira: Mamolekyu a nthunzi amapitirizabe kugundana ndi mamolekyu a mpweya, zomwe zimapangitsa kuti pakhale unyolo wozungulira pampu yonse. Njira imeneyi imapanga malo ogwirira ntchito pomwe mamolekyu a mpweya amakankhidwira ndi kugwidwa nthawi zonse, zomwe zimapangitsa kuti pakhale malo ambiri opumira mpweya.
5. Ma Baffles: Pofuna kupewa mamolekyu a mpweya kuti asabwerere m'chipinda chopanda mpweya, pampu yofalitsa mpweya imakhala ndi ma baffles kapena misampha yambiri. Ma baffles amenewa amagwira ntchito ngati chotchinga, zomwe zimathandiza kuti mpweya wopopedwa usabwerere m'mbuyo.
Ndikofunikira kudziwa kuti kugwira ntchito bwino kwa pampu yofalitsa madzi kumadalira zinthu zingapo monga kusankha madzi opopera, kapangidwe ka nozzle ndi kutentha kogwirira ntchito. Gawo lililonse liyenera kuyesedwa mosamala kuti ligwire bwino ntchito.
M'nkhani zaposachedwa, kupita patsogolo kwa ukadaulo wa mapampu ofalitsa nkhani kwayang'ana kwambiri pakukweza magwiridwe antchito ndikuchepetsa kuwononga chilengedwe. Ofufuza akufufuza madzi ena otulutsa pampu omwe ali ndi mphamvu zochepa zotenthetsera dziko lapansi komanso omwe alibe poizoni wambiri. Kupita patsogolo kumeneku kwapangidwa kuti kuchepetse kuwonongeka kwa chilengedwe komwe kumakhudzana ndi mafuta achikhalidwe ofalitsa nkhani.
Mwachidule, mapampu ofalitsa uthenga amathandiza kwambiri popanga ndi kusunga mpweya wochuluka m'mafakitale osiyanasiyana. Kumvetsetsa momwe mapampu awa amagwirira ntchito kumatithandiza kumvetsetsa njira zovuta zomwe zimagwiritsidwa ntchito popanga mpweya wabwino. Pamene ukadaulo ukupitirira kukula, tikuyembekezera kusintha kwina pakugwiritsa ntchito bwino mpweya wofalitsa uthenga komanso kuteteza chilengedwe.
