Isitolo esihlanzekile = umoya ohlanzekile
Ukuqalisa nokuvala injini endaweni evalekile, njengendawo yokulungisa izimoto, kubangela ukunqwabelana kwentuthu eyingozi. Uma sengeza ukuthi lo msebenzi uphindwa ngokwesilinganiso izikhathi eziyishumi nambili ngosuku, khona-ke isikali senkinga sibonakala sibonakala kakhulu. Ukuqinisekisa izimo zokusebenza eziphephile, amagesi akhipha umoya akhishwa ngokuqondile epayipini lokukhipha imoto esebenzisa okuthiwa yi-exhaust gas extractors. Ngokuya ngobukhulu be-workshop noma isiteshi sokuxilonga, izinketho ezahlukene zokususwa kwemikhiqizo evuthayo yengxube ye-fuel-air ifakiwe.
Amabhande - kodwa yini?
Okokuqala, ake sijwayelane nesimiso sokusebenza kwama-hoods. Kafushane nje, kuhlanganisa ukwenza i-vacuum lapho kuphuma amagesi aphuma epayipini le-exhaust lemoto. Lezi zokugcina zikhishwa ngaphandle kwesikhungo kusetshenziswa ipayipi elikhipha umoya eliguquguqukayo. Kuye ngobukhulu be-workshop, izixazululo ezihlukahlukene zokuklama zezinhlelo zegesi zokukhipha igesi zisetshenziswa. Encane, enendawo eyodwa noma ezimbili zokusebenza, okunamahingiswa okukodwa noma okuphindwe kabili noma ukushayelwa kwesigubhu, kanye nalokho okubizwa ngokuthi. ephathekayo (ehambayo) kanye nezinhlelo zaphansi. Ngakolunye uhlangothi, kuma-workshops eziteshi eziningi, ama-extractors ahambayo avame ukufakwa ukuze kuqinisekiswe ukuthi amagesi aphumayo akhishwa ngendlela efanele emotweni ehambayo ngaphambi kokuba ishiye isakhiwo sokusebenzela.
Eyodwa noma emibili
Ama-extractor exhaust eyodwa noma amabili asetshenziswa ezindaweni zokusebenzela zezimoto ezincane. Ahlanganisa isiphephetha-moya kanye nepayipi eliguquguqukayo (amashubhu) elinemibhobho exhunywe epayipini le-exhaust lemoto. Ezixazululweni ezilula, izintambo zilengiswa ezindongeni noma zelulwe ngama-balancers. Ngenxa yalokhu, ngemva kokunqamula i-nozzle epayipini lokukhipha imoto, ipayipi eliguquguqukayo libuyela esimweni salo sokuqala. Esinye isisombululo yilokhu okubizwa ngokuthi i-drum extraction. Igama layo livela enxebeni lepayipi eliguquguqukayo esigubhini esizungezayo esikhethekile. Umgomo wokusebenza uyafana nama-hoods angashadile namabili. Kodwa-ke, i-hose yokufaka umoya eguquguqukayo ilinyazwa esigubhu: kusetshenziswa idrayivu yasentwasahlobo noma ukusebenzisa i-motor kagesi (elawulwa ngesilawuli kude ezinguqulweni eziyinkimbinkimbi). I-extractor yesigubhu ivamise ukugxunyekwa ophahleni noma odongeni lweshabhu.
Iselula futhi iyaphatheka
Ukuthutha okuhambayo, okubuye kwaziwe ngokuthi isitimela sokuthutha, kusebenzisa inqola ekhethekile ehamba kujantshi ukuze ithwale amagesi akhipha umoya. Eyokugcina ifakwe kokubili ngobude ngokuphathelene neziteshi zokuhlola, futhi ngokuphambene ngemuva kwezimoto. Inzuzo yalesi sixazululo yikhono lokuxhuma ipayipi eguquguqukayo kumbhobho wokukhipha ohambayo, hhayi nje imoto emile. I-scraper ivaliwe ngokuzenzakalelayo ngemva kokuba imoto yokuhlola ishiye isango legaraji noma isiteshi sesevisi. Enye inzuzo ye-mobile uthuli extractor ukuthi kungenzeka ukuxhuma amapayipi amaningana aguquguqukayo kuwo. Kuye ngenombolo yabo, ingasebenza nomlandeli oyedwa noma ngaphezulu. Inguqulo yeselula kakhulu ye-hood isistimu ephathekayo (eguquguqukayo). Kulesi sixazululo, fan ibekwe ohlakeni olukhethekile oluhamba ngamasondo. Ngokungafani nezinhlelo ezichazwe ngenhla, inguqulo ephathekayo ayinayo i-nozzle kupayipi yokukhipha. Esikhundleni salokho, kukhona isixhumi esikhethekile esitholakala eduze ngangokunokwenzeka ekuphumeni. Laba bakamuva bakhishwa endaweni yokusebenzela ngosizo lwepayipi eliguquguqukayo.
Ishaneli iphansi
Futhi ekugcineni, uhlobo lokugcina lwe-exhaust outlet yilokho okubizwa ngokuthi uhlelo lwephansi. Njengoba igama lisho, imikhiqizo yenqubo yokushiswa kwengxube ye-air-fuel idluliselwa ekufakweni okungaphansi kwendawo yokusebenzela. Endabeni yamaphuzu anenani elincane lezindawo zokusebenza, isixazululo esilungile siwukuhluka kwayo ngekhebula eliguquguqukayo elibekwe esiteshini esikhethekile phansi. Inzuzo yalesi sixazululo ukuba khona unomphela kwekhebula, okuyinto ngesikhathi esifanayo engathathi indawo ezimweni lapho kungadingeki khona. Ububi obuyinhloko ukulinganiselwa kobubanzi bepayipi ngokwayo kanye nobukhulu bepayipi lokumunca. Enye inketho yesistimu yaphansi uhlelo olunamapayipi aguquguqukayo axhunywe kusokhethi esizinikezele saphansi. Inzuzo ebaluleke kakhulu ukuhamba kwayo: isisebenzi singayixhuma esokhethi lapho kuhlolwa khona imoto. Ukwengeza, kule nguqulo yesistimu yephansi, akukho mingcele kububanzi nobukhulu bepayipi lokumunca isisombululo esifihliwe phansi.
