Indlu yesikhwama noma isihlungi sesikhwama siyidivayisi yokuhlunga umoya isitshalo sokuxuba i-asphalt. Iyithuluzi elingcono kakhulu lokulawula ukungcoliswa kwezitshalo ze-asphalt. Isebenzisa inani lezikhwama ekamelweni ukuhlunga umoya. Umoya wenziwa ukuthi udlule ezikhwameni futhi ngenxa yalokho lonke uthuli luzonamathela ezikhwameni.
Izihlungi zezikhwama eziningi zizoba nezikhwama ezinde eziyisilinda zokuqoqa uthuli. Lezi zikhwama zizofakwa ngaphakathi kwamakheji ukuze zisekelwe. Amagesi azodlula kusukela ekugcineni kwesikhwama kuya ngaphakathi. Le nqubo izokwenza uthuli lunamathele ekugcineni kwangaphandle kwesihlungi sesikhwama. Indwangu elukiweyo noma enefefe isetshenziswa njengendlela yokuhlunga.
Izindlu zezikhwama, sezineminyaka eminingi zilawula uthuli esitshalweni se-asphalt. Basaqhubeka nomsebenzi wabo nanamuhla. Umqondo oyisisekelo uyafana, izinto ezintsha zokuhlunga nezindlela ezintsha zokuxazulula izinkinga zizenza zivumelane nezimo kunangaphambili.
Ukusetshenziswa kwesihlungi sesikhwama esitshalweni se-asphalt:
Isihlungi sesikhwama sesitshalo se-asphalt sisetshenziselwa ukulawula ukungcola. Kuzosiza ukuqeda i-dist namagesi ayingozi. Uthuli lukhiqizwa ngama-aggregate futhi isikhathi esiningi asifuni ukuthi uthuli olwengeziwe lungene emkhiqizweni wokugcina. Izokonakalisa umkhiqizo wokugcina. Amagesi ayingozi akhishwa ngenxa yesishisi esishisa isigubhu. Lamagesi kanye nothuli lwenziwa ukuthi ludlule ezikhwameni zokuhlunga ukuze kuhlanzwe.
Izihlungi zezikhwama zisebenza njengedivayisi yesibili yokulawula ukungcola. Abaqoqi uthuli abayinhloko yizihlukanisi ze-cyclone. Lezi zihlukanisi eziyinhloko zibamba uthuli olusindayo ngokumunca nokudala isishingishane ngaphakathi kwegumbi. Uthuli olulula namagesi ayingozi ngeke abanjwe yilokhu. Yilapho ukubaluleka kwezihlungi zezikhwama izitshalo zokuxuba itiyela iba khona. Igesi ngemva kokweqa isihlukanisi sesishingishane izohamba iye ngasegunjini elikhulu. Zonke izindlu zezikhwama zizoba neshidi leshubhu noma ifremu lapho izikhwama zilenga khona. Kukhona amapuleti ama-baffle ngaphakathi. Lawa ma-baffle plate azogcina uthuli olunzima futhi angawavumeli ukuthi alimaze izihlungi. Njengoba isihlungi sesikhwama sizosetshenziswa ngokuqhubekayo. Uthuli oludlula kuyo luzobhajwa kancane kancane phezu kwesihlungi semidiya. Lokhu kuzodala ukuphakama kwengcindezi futhi indlela yokuhlanza izosiza ukuhlanza izikhwama njalo.
Ukuhlanza izikhwama uhlelo oluzungezayo lwefeni phezulu kwesihlungi luvumela ukuhlanzwa kwezikhwama eziyi-8 kuphela ngesikhathi. Lokhu kuhle njengoba inani elincane lezikhwama zithola umfutho womoya omuhle. Ngakho-ke inqubo yokuhlanza isebenza kahle kakhulu. I-air pulse ekhishwa fan phezulu izosiza ekukhipheni ikhekhe lothuli elizokwakhiwa ngaphandle kwezikhwama. Kukhona indawo yokungena umoya ongcolile kanye nendawo yokukhipha umoya ohlanzekile. Phansi indlu yezikhwama izoba nendawo yokuphonsa uthuli oluqoqiwe.
Le nqubo isivumela ukuthi sisebenzise izikhwama ngokuqhubekayo ngaphandle kwenkinga. Kubiza kakhulu futhi kusebenza ngempumelelo.
Ukugcinwa kwezikhwama zokuhlunga zezitshalo ze-asphalt
Izikhwama zokuhlunga ezixubeni ze-asphalt zisetshenziswa ezivezwe emazingeni okushisa adlulele namagesi abi kakhulu. Kunezinye izimboni ezifaka ubunzima ezikhwameni zokuhlunga lezi wukuguquguquka okuvamile kwezinga lokushisa, ukuqala nokuvala imishini, ukushintsha amafutha ahlukahlukene. Ngezinye izikhathi indawo ezungezile enokhahlo kanye nothuli oluningi nomswakama futhi kubeka ingcindezi enkulu ezintweni zokuhlunga.
Ukucindezela ngaphakathi kwegumbi lokuhlunga isikhwama kufanele kugcinwe ukuze izikhwama ziqhubeke nokusebenza kahle. Nokho ezikhathini eziningi amakhasimende afuna ukusebenzisa imishini ngisho noma lina futhi lokhu kungase kube inhlekelele. Kunezimo lapho uphethiloli wesikhwama udale umonakalo omkhulu kuzihlungi zezikhwama futhi kudingeke ukuthi zishintshwe ngokushesha.
Ukushintsha izikhwama kuwumsebenzi odla isikhathi futhi oyisicefe odinga ukuthi isitshalo sivalwe futhi kuwumsebenzi ongcolile. Zonke izikhwama kufanele zikhishwe phezulu kwesisefo sesikhwama bese kushintshwa izikhwama ezintsha ekhejini elikhona. Lapho amakheji ehilelekile, umsebenzi uyisicefe.
Uma unohlobo olufanele lwesihlungi sesikhwama esifakelwe okokusebenza kwakho uqinisekiswa ngokusebenza okungenangcindezi. Xoxisana nathi uma ufuna ukuthi sifake izihlungi zezikhwama kunoma yiziphi izitshalo zakho ezikhona ze-asphalt.
