Ithini indlela yokufaka isifudumezi somoya?

I-heater duct yomoya isetshenziswa kakhulu ukushisisa ukugeleza komoya odingekayo ukusuka ekushiseni kokuqala kuya ezingeni lokushisa lomoya elidingekayo, elingafika ku-850°C. Isetshenziswe kabanzi kumalabhorethri amaningi ocwaningo lwesayensi nokukhiqiza afana ne-aerospace, imboni yezikhali, imboni yamakhemikhali namanyuvesi. Ifaneleka ngokukhethekile ekulawuleni izinga lokushisa okuzenzakalelayo, ukugeleza okukhulu kanye nokushisa okuphezulu okuhlanganisiwe izinhlelo kanye nokuhlolwa kwezesekeli.

II-heater ye-air ductinezinhlobonhlobo zokusetshenziswa: ingashisa noma iyiphi igesi, futhi umoya oshisayo okhiqizwayo womile, awunamswakama, awuhambisani, awushi, awuqhumi, awugqwali ngamakhemikhali, awungcolisi, uphephile futhi unokwethenjelwa, futhi indawo eshisayo iyashisa ngokushesha ( iyalawuleka).

Amafomu okufaka weizifudumezi zomoyangokuvamile zihlanganisa okulandelayo:

1. Ukufakwa kwe-Docking;

2. Ukufakwa kwe-plug-in;

3. Ukufakwa okuhlukile;

4. Izindlela zokufaka njengokufakwa kokungena. .

Abasebenzisi bangakhetha izindlela ezihlukene zokufaka ezifanele ngokusekelwe esimweni sabo sangempela. Ngenxa yobukhethekile bayo, i-casing material ye-heater duct heater ngokuvamile yenziwe ngensimbi engagqwali noma ishidi likathayela, kuyilapho izingxenye eziningi zokushisa zenziwe ngensimbi engagqwali. Ngakho-ke, lapho ukhetha, uma impahla yenziwe nge-carbon steel, kuyadingeka Iziqondiso ezikhethekile zokuqinisekisa ikhwalithi yokufaka nokuphila isikhathi eside.

Mayelana nokulawula i-heater ye-air duct, idivayisi yokuxhuma kufanele yengezwe phakathi kwefeni ne-heater ukuze kuqinisekiswe ukuthi i-heater iyaqala. Lokhu kufanele kwenziwe ngemuva kokuqala kwe-fan. Ngemva kokuba i-heater iyeka ukusebenza, isiphephetha-moya kufanele sibambezeleke isikhathi esingaphezu kwemizuzu engu-3 ukuze i-heater ingashisi kakhulu futhi yonakaliswe. Izintambo zesiyingi esisodwa kufanele zihambisane nezindinganiso ze-NEC, futhi ukusebenza kwegatsha ngalinye akufanele kudlule ku-48A.

Umfutho wegesi oshisiswe yi-heater yepayipi lomoya ngokuvamile aweqi ku-0.3kg/cm2. Uma ukucaciswa kwengcindezi kudlula lokhu okungenhla, sicela ukhethe i-heater circulation. Ukushisa okuphezulu kokushisa kwegesi nge-heater ephansi yokushisa akudluli ku-160 ° C; uhlobo lwezinga lokushisa eliphakathi alwedluli ku-260°C, kanti uhlobo lwezinga lokushisa eliphezulu aludluli ku-500°C.
