Ikhava engezansi ingasetshenziswa ngokuvundlile, mpo noma ngokuvundlile ukuze kuqinisekiswe ukusebenza kahle futhi akukho msindo.Ngokusebenzisa impahla eluhlaza enogqinsi oluncane, ingacindezelwa ukuze ihlangabezane nezidingo zendawo yokusebenza encane ngomshini yesimanje.Isihlangu sesitho sinendawo ebushelelezi, isimo esivamile nokubukeka okuhle, okwengeza umbala kusimo sethuluzi lomshini ukuze kuthuthukiswe izinga lethuluzi lomshini.Kunezinhlobo ezimbili ezahlukene zekhava engezansi.Kunezinhlobo ezimbili eziyinhloko, eyodwa uhlobo lwe-louver (eyaziwa kakhulu ngokuthi: uhlobo lomugqa owodwa), kanti enye iwuhlobo lwe-"U".Ukuma kokutsheka noma ukuma kwendlu kuthuthukisa ukukhishwa koketshezi.
Ngokuthuthukiswa okuqhubekayo kwezinto zokusebenza zemishini, izidingo zohlelo lokuvikela ziyathuthukiswa ngokufanayo.Ikakhulukazi, ukusetshenziswa kwama-servo motors kwenza ijubane lokucubungula imishini libe phezulu nangaphezulu, kwesinye isikhathi lifike ku-200m/min, okudinga izinto eziqinile ezingazweli kodwa ezinesisindo esincane.Ukuvikelwa.
Ngaphezu kwalokho, ukusetshenziswa kwekhava engezansi emkhakheni wezokwelapha, ukulinganisa, ukulawula okuzenzakalelayo kanye nobuchwepheshe bokudla kuya ngokuya kuba banzi.Lezi zimboni zidinga ikhava yokuzivikela ukuze ingangeni uthuli kanye nokudla.
Isembozo se-Bellow sisetshenziswa kabanzi futhi kabanzi endaweni yokuphakamisa yomugqa wokuhlanganisa wokukhiqiza izimoto.Ikhava yethu yokuvikela ingahlangabezana ngokugcwele nezidingo zokuphakama kwayo nokusebenza okushelelayo.
Cishe zonke izindawo ezidinga ukuvikelwa zingakhelwa futhi zikhiqizelwe wena ngesikhathi esifushane ngohlobo lwekhava ehlanganisiwe ebhonsayo.
1. Lolu hlobo lwesihlangu lunezici zokungesabi: ukunyathela, izinto eziqinile ezishayisanayo futhi ezingagugi, ukuphila isikhathi eside, ukuvala kahle nokusebenza okulula.
2. Izinto ezisetshenziswa kulo mkhiqizo azikwazi ukumelana nokupholisa, uwoyela kanye namafayili ensimbi.
3. Isembozo sokuzivikela sinezinzuzo ze-stroke ende kanye nokucindezelwa okuncane.
