Ikhanda lokufafaza elihlangene elishisayo elivulekile

Ukwesekwa komkhiqizo ngokwezifiso

Ijoyinti elivulekile elishisayo:Ijoyinti elivulekile elishisayo liyisifafazi esisethwe ngaphansi kwesimo sezithiyo ngaphansi kosilingi.Ngokuhlukanisa imisebenzi yengxenye yokuzwa kanye nengxenye yokufafaza ye-sprinkler evaliwe, umlilo ungazwakala ngokuphumelelayo futhi ucishwe ngisho nalapho kunezithiyo eduze nophahla.Umkhiqizo awunawo umsebenzi wokuchelela, umsebenzi wokuzwa kuphela.Ingxenye ezwa ukushisa ebekwe engxenyeni engezansi yendawo engaphezulu izwa ukushisa okubangelwa umlilo.Ukunisela nokucima umlilo kwenziwa ngekhanda lokufafaza elivulekile elixhunywe epayipini lesibili lomkhiqizo.
Izinga lokufaka:
1.Lo mkhiqizo uzofakwa ngezinga lokushisa elimakiwe elihambisana nezinga lokushisa elilindelekile endaweni yokufaka.Izinga lokushisa elizungezile lendawo yokufaka lo mkhiqizo kufanele ligcinwe lingaphansi kwezinga lokushisa eliphezulu le-ambient.Uma izinga lokushisa lomkhiqizo liphezulu kakhulu, lingabangela ukwehluleka.Ngaphezu kwalokho, lo mkhiqizo kufanele ufakwe engxenyeni lapho ukuphakama kwayo kusuka phansi kuya ophahleni kungadluli i-10m.
2.I-torque yokuqinisa ipayipi yalo mkhiqizo izoba ngu-30N·M, angeke yeqe ku-40N·M.sicela unake ukuthi ungasebenzisi amandla amaningi ekuqiniseni amapayipi.Ukuqina kakhulu kuzodala ukuvuza kwamanzi.
3.Ibanga phakathi kwengxenye ezwela ukushisa yalo mkhiqizo kanye nebhodi losilingi elifakiwe kufanele libe phakathi kuka-0.3m.
4.Lo mkhiqizo uzosethwa engxenyeni ngayinye ehlukaniswe yimishayo enwebeka ngaphezu kuka-0.4 m ukusuka endaweni yokufaka.Ngaphandle kokuthi ibanga elimaphakathi phakathi kwemishayo lingaphansi noma lilingana no-1.8m.
5.Lapho ububanzi noma ukujula kokunikezwa komoya kanye nepayipi lokukhipha umoya neshalofu kudlula u-1.2 m, umkhiqizo uzofakwa endaweni engaphezulu, futhi ikhanda lokufafaza elivulekile lizofakwa endaweni engaphansi yezithiyo zokufafaza njengepayipi lomoya.
6.Ikhanda lokufafaza elivulekile elixhuma uhlangothi lwesibili lomkhiqizo lizofakwa phakathi kwama-3.25 m ohlangothini oluvundlile kanye no-8.5 m ohlangothini oluqondile lwe-eksisi yomkhiqizo.
I-7.Umkhiqizo ngamunye ungaxhunywa namakhanda avuliwe angaphezu kwama-2.Uma amakhanda amabili okufafaza avulekile axhunyiwe, qiniseka ukuthi ayikho inkinga ngokulahlekelwa kwengcindezi ngaphambi kokufaka.
