Shenhai Explosion-Ubungqina
Izixhobo zombane ezomeleziweyo kufuneka zifakwe kwindawo ebiyelweyo eyilwe ngokufanelekileyo. Le casing ibalulekile kungekuphela nje ekuhlanganiseni izinto zombane kodwa nasekuzikhuseleni kwizoyikiso zangaphandle ezinje ngamasuntswana aqinileyo., ukufuma, kunye namanzi. Ezi zinto zibeka ingozi enkulu njengoko zinokukhokelela kwiisekethe ezimfutshane, ukwaphuka kwe-insulation, kunye nokukhutshwa kombane okunokuba yingozi.
Kuyaziwa ukuba izixhobo zombane zisengozini kwizinto zokusingqongileyo. Izingcolisi eziqinileyo, umzekelo, inokungena kwaye ibangele iisekethe ezimfutshane, ngelixa ukufuma kunokuthoba ubushushu, okukhokelela ekuvuzeni kunye neentlantsi - imeko eyingozi ngokwenene. Ukusebenzisa iindawo ezivaliweyo ezinomlinganiselo wokhuseleko ofanelekileyo kunokuthintela le mingcipheko.
Ngokomgangatho we-GB4208-2008, echaza amanqanaba okhuseleko kwindawo ebiyelweyo (Iikhowudi ze-IP), la manqanaba amelwe yikhowudi ye-IP elandelwa ngamanani amabini kwaye ngamanye amaxesha iileta ezongezelelweyo. Inani lokuqala libonisa umgangatho wokhuseleko kwizinto eziqinileyo, okwesibini kuchasene namanzi. Umzekelo, Indawo evalekileyo ebekwe kwi-IP54 inika inqanaba elithile lokhuseleko kwizinto eziqinileyo kunye nolwelo. I-GB4208-2008 ihlela ukhuseleko kwizinto eziqinileyo 6 amanqanaba kunye ngokuchasene namanzi ukungena 8 amanqanaba.
Xa kuziwa kwiindawo ezivaliweyo:
Ngeendawo eziphilayo eziveziweyo, Ubuncinci be-IP54 buyadingeka.
Ngeendawo ezigqunywe ngaphakathi, kufuneka kwakhona ibe yi IP54 ubuncinci.

| 0 | Ayikhuselekanga | |
| 1 | Thintela izinto eziqinileyo zangaphandle ezinobubanzi obungekho ngaphantsi kwe-50mm | Isixhobo sovavanyo esiyi-50mm spherical esinobubanzi be-diameter akufunekanga singene ngokupheleleyo kwi-casing |
| 2 | Thintela izinto eziqinileyo zangaphandle ezinobubanzi obungekho ngaphantsi kwe-12.5mm | Isixhobo sovavanyo esiyi-12.5mm esingqukuva esinobubanzi akufunekanga singene ngokupheleleyo kwisingxobo |
| 3 | Thintela izinto eziqinileyo zangaphandle ezinobubanzi obungekho ngaphantsi kwe-2.5mm | Isixhobo sovavanyo esiyi-2.5mm esingqukuva esinobubanzi akufunekanga singene ngokupheleleyo kwisingxobo |
| 4 | Thintela izinto eziqinileyo zangaphandle ezinobubanzi obungekho ngaphantsi kwe-1.0mm | Isixhobo sovavanyo esiyi-1.0mm esingqukuva esinobubanzi akufunekanga singene ngokupheleleyo kwisingxobo |

| 0 | Akukho khuselo | |
| 1 | Thintela nkqo ukuthontsiza kwamanzi | Ukuthontsiza okuthe nkqo akufuneki kube neziphumo eziyingozi kwisixhobo sombane |
| 2 | Thintela ukuthontsiza kwamanzi kwicala elithe nkqo xa iqokobhe lithambeka phakathi koluhlu 15 ° ukusuka kwicala elithe nkqo | Xa imiphezulu ethe nkqo ye-casing ithambekele ngaphakathi kwe-engile ethe nkqo ye 15 °, ukuthontsiza kwamanzi nkqo akufuneki kube nefuthe elibi kwisixhobo sombane |
| 3 | Ukukhuselwa kwemvula | Xa imiphezulu ethe nkqo ye-casing ithambekele ngaphakathi kwe-engile ethe nkqo ye 60 °, imvula akufanele ibe nempembelelo eyingozi kwisixhobo sombane |
| 4 | Anti splash amanzi | Xa utshiza amanzi kuwo onke amacala e-casing, akufanele kube nemiphumo eyingozi kwisixhobo sombane |
| 5 | Ukuthintela ukutshizwa kwamanzi | Xa utshiza amanzi kuwo onke amacala e-casing, akufanele kube nemiphumo eyingozi kwisixhobo sombane |
| 6 | Anti strong water spray | Xa utshiza amanzi anamandla kuwo onke amacala e-casing, ukutshiza okunamandla kwamanzi akufanele kube nemiphumo emibi kwizixhobo zombane |
| 7 | Ukuthintela ukuntywiliselwa kwexesha elifutshane | Xa i-casing ibhaptizwa emanzini kuxinzelelo oluchaziweyo kwixesha elithile, umthamo wamanzi angena kwi-casing awuyi kufikelela kwinqanaba eliyingozi |
| 8 | Uthintelo lokuntywila ngokuqhubekayo | Ngokwemiqathango ekuvunyelwene ngayo ngabo bobabini umenzi kunye nomsebenzisi, umthamo wamanzi angena kwi-casing awuyi kufikelela kwinqanaba eliyingozi emva kokungena emanzini ngokuqhubekayo |
Ukukhupha umoya:
Kwizixhobo zeClass I, ubuncinane be-IP54 (kumalungu aphilayo angakhanyiyo) okanye IP44 (iindawo eziphilayo ezigqunyiweyo) Iyafuneka.
Kwizixhobo zeClass II, ukulinganisa akufuneki kube ngaphantsi kwe IP44, kungakhathaliseki uhlobo lwamalungu angaphakathi.
Ukuba izixhobo zombane eziphuculweyo zine ukhuselekile ngaphakathi iisekethe okanye iinkqubo, ezi kufuneka zicwangciswe ngokwahlukeneyo kwiisekethe ezingakhuselekanga ngokwangaphakathi. Iisekethe ezingakhuselekanga ngokwasengqondweni mazihlaliswe kwikompatimenti enomlinganiselo ubuncinane we-IP30, iphawulwe ngesilumkiso: “Sukuvula ngelixa unamandla!”
Indawo ebiyelweyo yezixhobo zombane zokhuseleko olwandisiweyo ibalulekile ekukhuseleni amacandelo angaphakathi kuphazamiseko lwangaphandle kunye nokuqinisekisa ukusebenza kokugquma kweesekethe kuhlala kungaguquki., kungoko igama “indawo ebiyelweyo yokhuseleko.”
