Ukucinywa komlilo ngexesha elifanelekileyo kucetyiswa ukuba usebenzise umcimi wokucima umlilo. Kukho iintlobo ezininzi : i-foam-moya, i-carbon dioxide kunye nezicima umlilo, ezahluke kwiimpawu zobugcisa eziphambili.
Kule nqaku siza kuqwalasela umgaqo wesenzo kunye nendlela yokusebenzisa umlilo wokucima umlilo ngokuchanekileyo.
Yintoni i-carbon dioxide-fire extinguisher?
Isici esikhethekileyo somlilo we-carbon dioxide ukucima umlilo kukusetyenziswa kwe-carbon dioxide njengento yokucima umlilo kuyo, ukuze kungabi namlilo kunye nentsipho ehlala emlilweni.
Xa usebenzisa oko, kufuneka ukwazi ukuba umbane wokucima umlilo utshabalalisa izinto ezinokutsha ezivuthayo ngaphandle kokungenisa umoya kwaye akusebenzi ukucima i-sodium, i-potassium, i-aluminium, i-magnesium kunye nama-alloys. Kwakhona akunakusetyenziswa ukucima umntu ovuthayo, kuba ubuninzi beqhwa le-carbon dioxide obanjelwe elukhumbeni luya kubangela ubanda, kuba ubushushu balo -70 ° С.
Kunconywa ukuba isetyenziswe kwizityalo zoshishino, kwiimoto kwii-laboratories zamakhemikhali, kwiinkqubo zamandla kagesi phantsi koxinzelelo, kunye nakwiimyuziyam kunye neengqolowa zengqolowa, kuba i-carbon dioxide iphosa indawo yomsakazo kwaye iyanciphisa indawo engenazixhobo ezinokutsha kuze kube yilapho ukushisa komlilo kuphelile.
Ngokuxhomekeka kwindawo yokusetyenziswa, izicima umlilo zomlilo ze-carbon dioxide ziyizimoto, zasekhaya kunye nezoshishino, kuxhomekeke kubukhulu - eziphathekayo neziphathekayo.
Isixhobo nomgaqo wokusebenza komlilo wokucima umlilo
Isicima somlilo esiqhelekileyo sinesi sixhobo esilandelayo:
1 - isinyithi sessimbi; I-2-lever okanye i-shut-off device, i-3-siphon tube; 4 - intsimbi; 5 - ukuphatha ukuthumela; 6 - khangela okanye utywine; 7 - i-carbon dioxide.
Umgaqo wokusebenza kowomlilo wokucima umlilo osuselwe kwi-carbon dioxide isekelwe kwinto yokuba ukuhlawulwa kwekhabhoni dioxide kuthunyiswa yinkxalabo yayo (5.7 MPa), esetyenziswe xa ibhotile yokucima umlilo igcwele. Ngoko ke, xa i-lever igxininiswe, umrhumo we-carbon dioxide ukhawuleza uqhutywe kwi-tube ye-siphon kwi-bell, ngelixa lidlula kwimeko yombane ukuya kwiqhwa-njengaye, elinceda ukupholisa indawo apho i-jet iya kuhanjiswa khona.
Ukucinywa komlilo we-carbon dioxide-fire extinguisher
Ukusebenzisa umlilo wokucima umlilo ofunekayo:
- Khupha isheke okanye itywina.
- Ukuqondisa emlilweni insimbi.
- Cinezela iqhosha. Ukuba umbane wokucima umlilo ufakwe i-valve, uyibuyise ngokukhawuleza kweeyure uze uke.
Ukusebenzisa umcimi wokucima umlilo, akudingekile ukukhulula yonke into.
Imimiselo yokusetyenziswa kwecima yomlilo wekhabhoni dioxide
Ukusebenzisa umcimi wokucima umlilo akuzange kubangele ingozi, kuyimfuneko ukulandela imithetho ethile xa uyisebenzisa:
Xa ugcina, uhambelane nolawulo lokushisa -40 ° C ukuya ku-50 ° C, ugweme ukukhanya kwelanga kunye nemiphumo yokushisa.
Xa ucima, yisela intsimbi emlilweni ungasondeli ngaphezu kwe-1m.
Ungasisebenzisi umlilo wokucima umlilo emva komhla wokuphela (ngokuqhelekileyo iminyaka eyi-10).
Emagumbi avaliweyo, emva kokusebenzisa umcimi wokucima umlilo, kuyimfuneko ukuvuselela.
Ungavumeli ukuba izicima umlilo zisetyenziswe ngaphandle kwetywina kumenzi okanye kwenkampani yokubuyisela. Ukuqwalasela ixesha lokutshatyalaliswa komyalelo wokutshisa i-carbon dioxide izicima umlilo (ngonyaka) kunye nokuhlolwa kwengqibelelo ye-steel cylinder (yonke iminyaka emihlanu).
Yenza umsebenzi wokuhlola nokulungisa izicima umlilo kuphela kwizikhululo zokuhlawula ezizodwa.
Xa ukhetha i-carbon dioxide-fire extinguisher, kuyimfuneko ukukhokelwa yindawo yegumbi apho iya kubakho khona, kuba ubunzima obufunekayo bokuhlawulwa kunye nexesha lokunikezelwa kwe-arhente yokucima kuxhomekeke kule nto.
