IMINININGWANE YOMKHIQIZO
incazelo yomkhiqizo
Uma injini kaphethiloli ye-chainsaw isebenza, uphethiloli uyasha ngaphakathi kwesilinda bese amagesi okukhipha uphethiloli ekhishwa enjinini ngepayipi lokukhipha uphethiloli. Igesi evamile yokukhipha uphethiloli ayibonakali ngeso lenyama. Uma uphethiloli ungashiswanga ngokuphelele noma injini ingasebenzi kahle, kuzoba nama-hydrocarbon, i-carbon monoxide, ama-nitrogen oxide, kanye nezinhlayiya ze-carbon egesini yokukhipha uphethiloli, futhi igesi yokukhipha uphethiloli izobonakala imhlophe ngendlela engavamile, imnyama, noma iluhlaza okwesibhakabhaka. Singahlulela ukusha kukaphethiloli ngokusekelwe kumbala wokukhipha uphethiloli wenjini bese sithatha izinyathelo zokuxazulula izinkinga ezifanele.
Uma injini kaphethiloli isebenza, uphethiloli uyasha ngaphakathi kwesilinda bese amagesi okukhipha umoya ephuma enjinini ngepayipi lokukhipha umoya. Igesi yokukhipha umoya iqukethe ikakhulukazi umhwamuko wamanzi, i-carbon dioxide, kanye ne-nitrogen. Igesi evamile yokukhipha umoya ayibonakali ngeso lenyama.
Uma uphethiloli ungashiswanga ngokuphelele noma injini ingasebenzi kahle, kuzoba nama-hydrocarbon (HC), i-carbon monoxide (CO), ama-nitrogen oxide (NOx), kanye nezinhlayiya ze-carbon kugesi yokukhipha umoya, futhi igesi yokukhipha umoya izobonakala imhlophe ngokungavamile, imnyama, noma iluhlaza okwesibhakabhaka. Singahlulela ukusha kukaphethiloli ngokusekelwe kumbala wogesi wokukhipha umoya wenjini bese sithatha izinyathelo zokuxazulula izinkinga ezifanele.
1, Ukukhipha intuthu emhlophe
Intuthu emhlophe emhubheni wokukhipha umoya yakhiwe kakhulu yizinhlayiya zikaphethiloli noma umhwamuko wamanzi ezingakashiswa futhi zingakashiswa ngokuphelele. Ngakho-ke, noma yisiphi isimo esibangela ukuthi uphethiloli ungashiswa ngokuphelele noma amanzi angene esilindani sizobangela ukuthi umhubhe ukhiphe umusi omhlophe.
Izizathu eziyinhloko zokukhishwa kwentuthu emhlophe yizinjini zikaphethiloli ze-chainsaw yilezi ezilandelayo:
1. Izinga lokushisa liphansi futhi ingcindezi yesilinda ayanele, okuholela ekungakhiqizweni kahle kukaphethiloli, ikakhulukazi ngesikhathi sokuqala kokubanda lapho intuthu emhlophe ikhishwa emthonjeni wokukhipha umoya;
2. Amanzi okungena e-Muffler;
3. Okuqukethwe kwamanzi amaningi kuphethiloli, njll.
Uma i-chainsaw iqala ukubanda, i-exhaust ikhipha intuthu emhlophe. Uma intuthu emhlophe inyamalala ngemva kokuba injini ifudumale, kufanele ibhekwe njengento evamile. Uma injini ye-chainsaw isakhipha intuthu emhlophe ngesikhathi sokusebenza okuvamile, kuyiphutha. Iphutha kufanele lisuswe ngokuhlanza amanzi aku-muffler, ukufaka esikhundleni sikaphethiloli, nezinye izindlela.
2, Ukukhipha intuthu eluhlaza okwesibhakabhaka
Intuthu eluhlaza okwesibhakabhaka emhubheni wokukhipha umoya ikakhulukazi iwumphumela wamafutha amaningi angena ekamelweni lokushisa futhi ahlanganyele ekushiseni. Ngakho-ke, noma yisiphi isizathu esibangela ukuba uwoyela ungene ekamelweni lokushisa sizobangela umusi oluhlaza okwesibhakabhaka ovela emhubheni wokukhipha umoya.
Izizathu eziyinhloko zokukhishwa kwentuthu eluhlaza okwesibhakabhaka yizinjini ze-chainsaw yilezi ezilandelayo:
1. Ukuguguleka kwezindandatho zepiston, ukuphuka kwezindandatho zepiston, kanye nokujikeleza kwezimbobo zezindandatho zepiston ndawonye;
2. Ukuhlanganiswa okungalungile noma ukwehluleka kokuguga kwezivalo zikawoyela, ukulahlekelwa umsebenzi wokuvala;
3. Ukuguguleka kwesiqondiso se-valve;
4. Ukuguga okukhulu kwamapistoni nezindonga zesilinda;
5. Injini ifakwe ohlangothini noma iguqulwe;
6. Ukuvaleka kwe-respirator;
7. Izinga likawoyela alilungile;
8. Inani elikhulu lamafutha elingeziwe.
Uma kukhona ukungasebenzi kahle kwentuthu eluhlaza okwesibhakabhaka enjinini, into yokuqala okufanele uyihlole ukuthi uwoyela osesaheni ugcwele ngokweqile yini. Okulandelayo, ngokuvamile kuyadingeka ukuqaqa nokuhlola umshini ukuze kutholakale imbangela bese kutholakala ikhambi lokuxazulula inkinga.
3, Ukukhipha intuthu emnyama
Uma ipayipi lokukhipha umoya le-chainsaw likhipha intuthu emnyama, kungenxa yokuthi uphethiloli awukashiswa ngokuphelele futhi uphethiloli wenjini uqukethe izinhlayiya zekhabhoni emnyama.
Ukushiswa okuphelele kukaphethiloli kudinga isilinganiso esithile sikaphethiloli nomoya ukuze kugcinwe ekamelweni lokushiswa. Uma isilinganiso somoya ekamelweni lokushiswa siphansi kakhulu noma siphezulu kakhulu, singabangela injini ukuthi ikhiphe intuthu emnyama. Ngakho-ke, izizathu eziyinhloko zokuthi kungani izinjini zikaphethiloli ezincane ze-chainsaw zikhipha intuthu emnyama yilezi ezilandelayo:
1. I-nozzle eyinhloko ye-carburetor igugile;
2. Isihlungi somoya simanziswa noma sivinjwe uthuli oluningi, okuholela ekumelaneni nokudla ngokweqile kanye nomthamo onganele wokudla;
3. Ukusebenza ngokweqile kwenjini;
4. I-nozzle eyinhloko ye-carburetor ikhethwe ngendlela engafanele. Isibonelo, uma injini isetshenziswa ezindaweni eziphakeme, ngenxa yokwehla kokuqukethwe komoya-mpilo emkhathini, kufanele kukhethwe i-nozzle eyinhloko ekhethekile yokuphakama okuphezulu, ngaphandle kwalokho kungaholela entuthwini emnyama.
Ezinjini zikaphethiloli ezikhipha intuthu emnyama, ukuhlolwa nokuxazulula izinkinga kungenziwa ngokufaka isihlungi somoya endaweni entsha, ukufaka i-nozzle eyinhloko, nokuqinisekisa ukuthi injini igcwele ngokweqile.
