Ukucima umlilo ngesikhathi esifanele kuphakanyiswa ukuthi kusetshenziswe ukucima umlilo. Kunezinhlobo eziningana : i-air-foam, i-carbon dioxide nezicisha umlilo, okuhlukile kwezinye izici eziyisisekelo zobuchwepheshe.
Kulesi sihloko sizocabangela isimiso sesenzo nokuthi singasebenzisa kanjani ukucima umlilo ngomlilo ngendlela efanele.
Kuyini ukucisha umlilo wokucima umlilo?
Isici esikhethekile somlilo wokucima umlilo somlilo i-carbon dioxide njengenhlangano yokucima umlilo kulo, ukuze kungabikho umlilo nosizi oluhlala emlilweni.
Uma usebenzisa, udinga ukwazi ukuthi umlilo wokucima umlilo ungabhubhisa izinto ezivuthayo ezivuthayo ezingashisi ngaphandle kokungenisa umoya futhi ukuthi akusebenzi ukucima i-sodium, i-potassium, i-aluminium, i-magnesium nama-alloys. Futhi angeke isetshenziselwe ukucima umuntu ovuthayo, ngoba inqwaba efana neqhwa le-carbon dioxide eboshwe esikhumbeni izobangela ama-frostbite, ngoba izinga lokushisa layo li--70 ° С.
Kunconywa ukuba isetshenziswe ezitshalweni zezimboni, ezimotweni ezinama-laboratories amakhemikhali, ezindaweni zokufakelwa kagesi ngaphansi kwezingcindezi, ngisho nasamamyuziyamu nezinqolobane zomlando, njengoba i-carbon dioxide igubungula indawo engumlilo futhi ihlanza imvelo yomswakama ongenamlilo kuze kube yilapho ukushisa komlilo kuphelile.
Ngokuya endaweni yokusebenzisa, izicima umlilo zomlilo ziyizimoto, ezifuywayo nezimboni, futhi ngokuya ngobukhulu - eziphathekayo neziphathekayo.
Idivayisi kanye nemigomo yokusebenza komcibisholo wokucima umlilo we-carbon dioxide
Isicima umlilo esivamile esivamile sinedivaysi elandelayo:
1 - steel cylinder; 2 - i-lever noma i-shut-off device, i-tube - 3 ye-siphon; 4 - insimbi; 5 - thinta ukuze uthumele; 6 - hlola noma uphawu; 7 - i-carbon dioxide.
Isimiso sokusebenza komcibisholo wokucima umlilo njengesibhakabhaka sincike ekutheni ukukhokhiswa kwekhabhoni dioxide kuthathelwe indawo ngokucindezela kwayo (5.7 MPa), esethwe lapho ibhodlela lokucima umlilo ligcwala. Ngakho-ke, lapho i-lever icindezelekile, umshini we-carbon dioxide uphonsela ngokushesha kwi-tube ye-siphon kuya enhlokweni, kuyilapho udlula kusuka esimweni se-liquid kuze kube seqhwa-elilodwa, okusiza ukupholisa indawo lapho i-jet izoqondiswa khona.
Ukucisha umlilo we-carbon dioxide
Ukusebenzisa umcimazi wokucima umlilo oshisayo:
- Vula isheke noma uphawu.
- Ukuqondisa emlilweni insimbi.
- Cindezela i-lever. Uma umcimazi wokushisa umlilo ufakwe i-valve, vula itholakale kuze kube yilapho liyeka.
Ukusebenzisa ukucima umlilo, akudingekile ukukhulula yonke into.
Imigomo yokusetshenziswa komcibisholo wokucima umlilo we-carbon dioxide
Ukusebenzisa ukucisha umlilo akuzange kubangele ukulimala, kubalulekile ukulandela imithetho ethile lapho uyisebenzisa:
Uma ugcina, uhambisane nombuso wokushisa -40 ° C kuya ku-50 ° C, gwema ukukhanya kwelanga kanye nemiphumela yokushisa amadivayisi.
Uma ucima, uletha insimbi emlilweni ungasondeli ku-1m.
Ungasebenzisi umlilo wokucima umlilo ngemuva kokuphela kwesikhathi (ngokuvamile iminyaka engu-10).
Emagumbini avaliwe, emva kokusebenzisa ukucisha umlilo, kuyadingeka ukuba uvuselele.
Ungavumeli ukucima umlilo kusetshenziswe ngaphandle kwephawu kumkhiqizi noma inkampani yokuvuselela. Qaphela isikhathi sokuvuselelwa kokugunyazwa kwezicima umlilo (ngonyaka) kanye nokuhlolwa kobuqotho be-steel cylinder (njalo eminyakeni emihlanu).
Yenza umsebenzi wokuhlola nokulungisa izicima umlilo kuphela eziteshini zokushaja ezikhethekile.
Uma ukhetha ukucima umlilo, kudingeka ukuthi uqondiswe yindawo ekamelweni lapho kuzobe khona khona, ngoba ubukhulu obudingekayo bokukhokha kanye nobude bokunikezwa kwe-agent yokucima kuxhomeke kulokhu.
