Pakalipano, njira yodziwika kwambiri yodula chitoliro yomwe amagwiritsidwa ntchito ndi opanga chitoliro cha zitsulo zozungulira ndi kudula kwa plasma. Pakudula, utsi wambiri wachitsulo, ozoni, ndi nitrogen oxide udzapangidwa, zomwe zidzaipitsa kwambiri chilengedwe. Chinsinsi chothetsera vuto la utsi ndi momwe mungakowerere utsi wonse wa plasma muzochotsa fumbi kuti mupewe kuwonongeka kwa mpweya.

Pakudula kwa plasma kwa mapaipi achitsulo ozungulira, zovuta pakuchotsa fumbi ndi:
1. Mpweya wozizira wochokera kumphepete mwa doko loyamwitsa umalowa mu doko loyamwa kuchokera kunja kwa kusiyana kwa makina ndipo mpweya wa mpweya ndi waukulu kwambiri, zomwe zimapangitsa kuti utsi wonse ndi mpweya wozizira mu chitoliro chachitsulo ukhale waukulu kuposa momwe mpweya wabwino umakokera. wosonkhanitsa fumbi, zomwe zimapangitsa kuti zikhale zosatheka kuyamwa kwathunthu utsi wodula.
2. Mphuno ya mfuti ya plasma imawombera mpweya kumbali ziwiri zosiyana panthawi imodzi panthawi yodula, kotero kuti utsi ndi fumbi zimatuluka kumapeto onse a chitoliro chachitsulo. Komabe, ndizovuta kubwezeretsa utsi ndi fumbi bwino ndi doko loyamwa lomwe limayikidwa mbali imodzi ya chitoliro chachitsulo.
3. Popeza gawo lodula liri kutali ndi malo olowera fumbi, mphepo yomwe imafika kumalo olowera kumapangitsa kuti zikhale zovuta kusuntha utsi ndi fumbi.

Kuti izi zitheke, mfundo zamapangidwe a vacuum hood ndi:
1. Mpweya wa mpweya womwe umakokedwa ndi wosonkhanitsa fumbi uyenera kukhala wochuluka kuposa kuchuluka kwa utsi ndi fumbi lopangidwa ndi kudula kwa plasma ndi mpweya mkati mwa chitoliro. Kuchuluka kwa mpweya woipa woipa uyenera kupangidwa mkati mwa chitoliro chachitsulo, ndipo mpweya wambiri wakunja suyenera kuloledwa kulowa m'chitoliro chachitsulo momwe zingathere kuti ugwire bwino utsi mu fumbi lotolera.
2. Tsekani utsi ndi fumbi kumbuyo kwa kudula kwa chitoliro chachitsulo. Yesetsani kuteteza mpweya wozizira kuti usalowe mkati mwa chitoliro chachitsulo polowera kolowera. Kuponderezedwa kolakwika kumapangidwa mkatikati mwa chitoliro chachitsulo kuti utsi ndi fumbi zisatuluke. Chinsinsi ndicho kupanga zida zotsekereza utsi ndi fumbi. Zimapangidwa modalirika, sizimakhudza kupanga bwino, ndipo ndizosavuta kugwiritsa ntchito.
3. Mawonekedwe ndi malo oyika malo olowera. Doko loyamwa liyenera kugwiritsidwa ntchito kuyamwa utsi wambiri ndi fumbi mkati mwa chitoliro chachitsulo mu chitoliro kuti chikwaniritse. Onjezani chododometsa kumbuyo kwa kudula kwa mfuti ya plasma kuti musunge utsi ndi fumbi mkati mwa chitoliro chachitsulo. Pambuyo pa nthawi ya buffering, imatha kuyamwa kwathunthu.

muyeso weniweni:
Ikani chiwombankhanga cha utsi pa trolley mkati mwa chitoliro chachitsulo ndikuchiyika pafupifupi 500mm kuchokera kumalo odulira mfuti ya plasma. Imani kwa kanthawi mutadula chitoliro chachitsulo kuti mutenge utsi wonse. Zindikirani kuti nsonga ya utsi iyenera kuyikidwa bwino pamalowo mutadula. Kuonjezera apo, kuti kuzungulira kwa trolley yoyendetsa utsi ndi chitoliro chachitsulo chigwirizane wina ndi mzake, ngodya ya gudumu la trolley yoyendayenda iyenera kukhala yogwirizana ndi ngodya ya chogudubuza chamkati. Pakuti plasma kudula lalikulu-m'mimba mwake wozungulira weld mipope ndi awiri a 800mm, njira angagwiritsidwe ntchito; kwa mapaipi okhala ndi m'mimba mwake osakwana 800mm, utsi ndi fumbi lokhala ndi mainchesi ang'onoang'ono silingatuluke kuchokera kunjira yotulutsira chitoliro, ndipo palibe chifukwa chokhazikitsa chotchinga chamkati. Komabe, polowera utsi wa utsi woyamba, payenera kukhala chododometsa chakunja kutsekereza kulowa kwa mpweya wozizira.
