Disadvantages:
ʻOku nau bulky pea ʻoku ʻi ai ʻenau ngaahi fie maʻu pau ki he ngaahi uaea, ngaahi hokotanga hui, conduits, linings, mo e nima (ʻOku totonu ke tatau ʻa e inisi honau matolu ʻi loto ʻo e foʻi mama fakamaʻu ʻi he nima mo e inisi honau matolu ʻi tuʻa ʻo e nima pea maʻu ia ʻaki ha lahi foʻi nati; Kapau ʻoku fakaʻaongaʻi e nima ukamea, ʻoku totonu ke silaʻi kinautolu ʻaki hono faʻo ʻo hangē ko hono tuʻutuʻuní; Kapau ʻoku fakaʻaongaʻi ha nima taʻe ʻi ai ha keipolo, kuo pau ke silaʻi ʻa e huʻanga ʻo fakatatau ki he ngaahi fie maʻu angamaheni). ʻOku ʻikai ngofua ke fakaava ʻa e hiva lolotonga hono fakaivia ʻi he ngaahi ʻatakai fakatuʻutamaki; ʻOku fie maʻu ha ngaahi meʻangaue makehe ʻi hono fakaava ʻo e hiva, pea ʻe lava ke hoko ha ngaahi meʻa fakatuʻutāmaki ʻi hono fola mo tokangaʻi hala hono folá. ʻOku ʻikai ngofua ke Flameproof ʻa e ngaahi puha ʻi he souni 0 pea ʻoku angamaheni ʻaki hono fakaʻaongaʻi ki he moto, Māmá, mo e alā meʻa pe.
Intrinsically faʻahinga malu:
Tefitoʻi Moʻoni ʻo e Maluʻi Fakaʻauhá:
Intrinsically malu, pe “Malu ʻi he feituʻu ʻoku ʻikai,” ʻoku ʻuhinga ia ki ha tefitoʻi moʻoni ʻo e maluʻi ʻo e pa ʻa ia ʻoku fakangatangata ai ʻa e ivi ʻo e ʻuhila pe ngaahi nunuʻa vela ʻoku faʻu ʻi ha meʻangaue pe ko hono ngaahi uaea fehokotaki ki ha tuʻunga ʻoku ʻikai lava ʻo vela. ʻOku ʻuhinga ʻeni ʻi he ngaue angamaheni pe ngaahi tuʻunga pau ʻo e fehalaaki, ʻikai ha fili fakafepakiʻi ʻE lava ke tutu ʻa e tuifio. ʻOku kau ʻi he ngaahi tefitoʻi founga maluʻi ʻa e fakangatangata ʻo e voltage mo e lolotonga pea mo e capacitance mo e inductance ʻo e circuit, vahevahe ki he Type ia (fakaʻata ʻa e fehalaaki ʻe ua) mo e Type ib (fakaʻata ha foʻi fehalaaki ʻe taha).
Ngaahi Lelei:
ʻOku ʻikai fie maʻu ki he ngaahi meʻangaue ha ngaahi keipolo makehe, ʻai ke malu ange ki he kau ngaue ke tokangaʻi mo monomono, pea ʻe lava ke fakaava ʻa e ngaahi takafi lolotonga ʻa e fakaʻuhila.
Disadvantages:
ʻOku ʻikai feʻunga ia ki he ngaahi meʻangaue malohi maʻolunga pea ʻoku angamaheni ʻaki hono fakaʻaongaʻi ki he ngaahi meʻangaue ʻoku maʻulalo ʻa e malohi ʻi hono fua, mapuleʻi, mo e fetuʻutaki. ʻIb’ ʻe lava ke ngaue ʻa e faʻahinga ʻi he Souni 0; ʻIb’ ʻe lava ke ngaue ʻa e faʻahinga ʻi he Souni 1.
Faʻahinga ʻo e Positive Pressure:
Tefitoʻi Moʻoni ʻo e Maluʻi Fakaʻauhá:
Ko e tefitoʻi moʻoni ʻo e malohi lelei ʻOku kau ʻi he faʻahinga maluʻi ʻo e pa fakahu ʻa e ʻea foʻou pe kasa inert ʻi ha teke malohi pau ki he ʻaʻa, taʻofi ʻa e ngaahi kasa vela mei he hu ki ai mo e, ko ia, taʻofi ʻa e ngaahi maʻuʻanga afi mei he fetuʻutaki mo e ngaahi kasa ʻoku pa, ʻo taʻofi ai ʻa e ngaahi pa. ʻOku kau ʻi he ngaahi meʻa mahuʻinga ki he ngaahi meʻangaue fakaʻuhila ʻoku teke malohi ʻa hono tauhi ʻo ha kasa maluʻi (ʻea foʻou pe kasa inert) teke malohi ʻi loto ʻi he puha ʻoku lahi ange ʻi he 50 Pascals. ʻOku kau ʻi he ngaahi fie maʻu ki he ngaahi meʻangaue fakaʻuhila ʻoku pressurized: ʻa e hiva, Maʻuʻanga Fakamatala, pea kuo pau ke matuʻuaki ʻenau ngaahi fetuʻutaki 1.5 liunga taimi ʻa e lahi taha ʻo e teke malohi lelei ʻi he tapuni ʻa e ngaahi feituʻu exhaust kotoa pe ʻi he ngaahi tuʻunga ngaue angamaheni ʻo hange ko ia ʻoku fakamahinoʻi ʻe he kautaha naʻa nau faʻu, mo ha teke malohi siʻisiʻi taha ʻo e 200Pa.
