UKhuseleko loKuqhushumba kwi-Automation ye-Industrial: Ukubeka phambili uKhuseleko ngaphezu kweNzuzo
Ukukhuselwa kogqabhuko-dubulo akuyomfuneko nje yokuthotyelwa—ngumgaqo wokhuseleko osisiseko. Njengoko abavelisi bee-automation baseTshayina besanda kumashishini asemngciphekweni omkhulu afana neekhemikhali zepetroli, imigodi, kunye namandla, ukuqonda imigangatho yokukhusela uqhushumbo kubaluleka kukhuphiswano lwehlabathi kunye nokhuseleko lokusebenza.
INzululwazi eNgemva koKuqhushumba koShishino
Ukudubula kufuna izinto ezintathu ezibalulekileyo:
- Into eqhumayo-Iigesi (i-hydrogen, i-methane), ulwelo (utywala, ipetroli), okanye uthuli (iswekile, isinyithi, umgubo)
- OxidizerNgokuqhelekileyo kukho ioksijini emoyeni
- Umthombo wokutshisa-Iintlantsi, iindawo ezishushu, ukukhutshwa okumileyo, okanye ukusabela kweekhemikhali
Umgaqo osisiseko wokuthintela ugqabhuko-dubulo ubandakanya ukuphelisa nayiphi na enye yezi zinto zintathu.
Ukuqonda iimpawu zeSixhobo soBonelelo: "Ex ed IIC T6"
Oku kuphawulwa kuqhelekileyo kwisixhobo sokuthintela uqhushumbo kubonisa:
- Ex: Ukuthotyelwa kwemigangatho yokukhusela uqhushumbo
- e: Ukunyuka koyilo lokhuseleko
- d: Indawo ebiyelweyo engenamlilo
- IIC: Ifanelekile kwiigesi ezinomngcipheko ophezulu (i-hydrogen, i-acetylene)
- T6: Elona qondo lobushushu liphezulu ≤85°C (ikhuselekile kwizinto ezineendawo ezisezantsi zokutshisa)
Iindlela ezingundoqo zoKhuseleko lokuqhambuka
Indawo evalekileyo engatshiyo (Ex d)
Ilungiselelwe ngokukodwa ukuqulatha uqhushumbo lwangaphakathi kunye nokuthintela ukuvutha kweatmospheres eziyingozi zangaphandle.
Ukhuseleko lwangaphakathi (Eks i)
Inciphisa amandla ombane ukuya kumaqondo angaphantsi koko kufunekayo ukubangela ukuvutha, nangexesha leempazamo. Ifuna izithintelo zodwa ukugcina ukhuseleko kuyo yonke inkqubo.
UHlelo lweNdawo eyiNgozi: Imimandla, amaQela eGesi kunye noHlelo loBubushushu
UHlelo loMmandla (iMigangatho ye-IEC)
- Zowuni 0: Ubukho obuqhubekayo bomoya oqhumayo
- Indawo yoku-1: Ubukho obunokwenzeka ngexesha lemisebenzi eqhelekileyo
- Indawo yesi-2: Ubukho obunqabileyo okanye obufutshane bomoya oqhumayo
IGas Group Classification
- IIA: Iigesi ezinobungozi obuphantsi (propane)
- IIB: Iigesi ezisemngciphekweni ophakathi (ethylene)
- IIC: Iigesi ezinobungozi obuphezulu (i-acetylene, i-hydrogen)
Uqondo lobushushu
| T-Class | Ubushushu boMphezulu obona buninzi |
|---|---|
| T1 | ≤450°C |
| T6 | ≤85°C |
IiNgozi zeMbali: Izifundo kuKhuseleko
- I-BP Texas City (2005): Iingozi ezili-15 ezibangelwa kukutshiswa komphunga wehydrocarbon
- EBuncefield, UK (2005): Ugqabhuko-dubulo olukhulu lomoya olubangwa kukugcwala kwetanki
- I-Imperial Sugar, USA (2008): Ukudubula kothuli kubulale abantu abali-14 ngenxa yokungahoywa ngokwaneleyo
Ezi ntlekele zigxininisa ukubaluleka kokhuseleko lwenkqubo yokukhusela ugqabhuko-dubulo oluqinisekisiweyo, olufanelekileyo kwindawo.
Ukukhetha Izixhobo eziziSebenzisayo eziKhuselekileyo: Iingqwalasela eziphambili
Xa ukhetha izisombululo ezizenzekelayo kwindawo ezinobungozi, soloko uqinisekisa:
- Ngaba isixhobo siyahambelana neemfuno zakho zowuni kunye neqela legesi?
- Ingaba iqondo lobushushu lifanelekile kwisicelo sakho?
- Ngaba onke amacandelo ayinxalenye yenkqubo eqinisekisiweyo yokuthintela uqhushumbo?
Ungaze ulalanisekwimigangatho yokukhusela ugqabhuko-dubulo. Ukhuseleko lumele lube yeyona nto iqhubayo ekwenzeni izigqibo zoyilo—kuba oko kusesichengeni kunabela ngaphaya kotyalo-mali lwemali kubomi babantu.
