Kuyaziwa kabanzi ukuthi zombili izindlala zekhebula ezingaqhumi kanye namabhokisi okuhlangana enziwe ngensimbi engagqwali noma nge-aluminium alloy die-casting., futhi babelana ngezinga elifanayo lesilinganiso sokuvikela ukuqhuma. Lezi zisetshenziswa ngokuyinhloko ezimbonini ezivame ukuba nezingozi zomlilo neziqhumane, njengamakhemikhali, isitoreji kanye nezinto zokuhamba, ezemithi, ezempi, kanye nemikhakha ye-petroleum. Nokho, abaningi bangase bangawuqondi ngokugcwele umehluko phakathi kwezindlala zekhebula ezingaqhumi namabhokisi okuhlangana. Ake ngicacise ukungezwani kwabo.
Umehluko oyinhloko usekusetshenzisweni kwazo ngokulandelana kanye nobubanzi bokusebenza. Izindlala zekhebula ezingaqhumisi zisetshenziswa uma ubude bezintambo bude kakhulu, okwenza kube nzima ukuxhuma ngomsele, noma lapho i-wiring inokugoba okuningi nokuhlukana. Basiza ekwenzeni lula ukuxhumana kwalezi zindlela zezintambo eziyinkimbinkimbi.
Ngokolunye uhlangothi, amabhokisi okuhlangana angaqhumi asebenza ngenjongo ehlukile. Zisetshenziswa lapho ukuxhumana kwezintambo zangaphandle, ukusatshalaliswa, noma izinto zikagesi zidinga izindlu zokuzivikela. Lawa mabhokisi okuhlangana ngokuvamile afika namatheminali axhumayo futhi angavama ukuhlakazwa ukuze kube lula ukusetshenziswa..
