Ukuhlaziywa kwemodi yokwehluleka kanye nemiphumela kuyinqubo yokubukeza izingxenye eziningi ngangokunokwenzeka, izinhlangano, kanye nezinhlelo ezingaphansi ngangokunokwenzeka ukuze kutholakale izindlela zokwehluleka ezingaba khona ohlelweni kanye nezimbangela nemiphumela yazo. Kuyithuluzi elihle lokuhlaziywa kokwehluleka, njengoba kusiza ukuvimbela ukwehluleka noma ukunciphisa umthelela wazo. Ngaphezu kwalokho, kungathuthukisa ikhwalithi, ukuthembeka, kanye nokuphepha kohlelo noma umkhiqizo. Lokhu kungaholela ekwanelisekeni kwamakhasimende okuthuthukisiwe kanye nokwethembeka, kanye nezindleko ezincishisiwe kanye nezingozi ezihlobene nokwehluleka. I-FMEA ngokuvamile ihilela izinyathelo ezinhlanu ezilandelayo:
Isinyathelo 1: Buza ukuthi iyiphi ingxenye yebhizinisi eyinkinga?
Isinyathelo sesi-2: Dala iqembu elingasebenzisana.
Isinyathelo 3: Khombisa futhi uchaze zonke izinyathelo.
Isinyathelo 4: Thola izindlela zokwehluleka.
Isinyathelo 5: Beka izinto ezibalulekile ngokusekelwe ku-RPN.
Vele, singasebenzisa futhi imodi ye-FEMA ekuhlolweni kwekhwalithi yeamavalvu olwandle.
Isinyathelo 1: Thola Izindlela Zokwehluleka Ezingaba Khona
Bhala zonke izindlela ezingaba khonaamavalvu olwandlekungahluleka (isib. ukuvuza, ukugqwala, ukuphuka komshini).
Isinyathelo 2: Hlaziya Izimbangela Nemiphumela
Cabanga ngezigaba ezahlukene: ukuklama, ukukhiqizwa, kanye nokusebenza. Thola izimbangela eziyinhloko zemodi ngayinye yokwehluleka. Hlola imiphumela engaba khona yokwehluleka ngakunye ohlelweni, ukuphepha, kanye nokusebenza.
Isinyathelo 3: Bala Izinombolo Zokubaluleka Kwengozi (RPN)
Hlola ubukhali (S), ukwenzeka (O), kanye nokutholwa (D) kwemodi ngayinye yokwehluleka. Nikeza amaphuzu ngobukhali, ukwenzeka, kanye nokutholwa.
Bala i-RPN yemodi ngayinye yokwehluleka: RPN = S × O × D.
Isinyathelo 4: Thuthukisa Izenzo Zokunciphisa Ubunzima
Beka phambili izindlela zokwehluleka ngokusekelwe kuma-RPN azo. Gxila ezintweni ezine-RPN ephezulu kuqala. Sebenzisa izinyathelo zokulungisa ezifana nokushintsha komklamo, ukuthuthukiswa kwezinto, kanye nokuhlolwa okuthuthukisiwe. Thuthukisa izindlela zokuvimbela kanye nokuhlolwa kokulawula ikhwalithi.
Isinyathelo 5: Sebenzisa futhi Uqaphe
Hlanganisa izenzo zokulungisa enqubweni yokukhiqiza. Qapha njalo ukusebenza kwe-valve kanye nokusebenza kahle kwezenzo zokunciphisa.
Isinyathelo 6: Buyekeza futhi Ubuyekeze
Vuselela njalo i-FMEA ngedatha entsha kanye nokuqonda. Yenza ukubuyekezwa njalo ukuqinisekisa ukuthi i-FMEA ihlala yamanje. Yenza izinguquko ngokusekelwe kwimpendulo, ubuchwepheshe obusha, kanye nezinqubo ezithuthukisiwe.
Ngokubhekana ngendlela ehlelekile nezindlela zokwehluleka ezingaba khona, i-FMEA iyasizaabahlinzeki bama-valve asolwandlefuthiabakhiqizi bama-valve asolwandleukuthuthukisa ikhwalithi kanye nokuthembeka kwemikhiqizo yabo.
