Lapho ukhetha amandla nezinto ezibonakalayo ze-isifudumezi sepayipi likawoyela, izici ezilandelayo ezibalulekile zidinga ukucatshangelwa:
Ukukhetha amandla
1. Isidingo sokushisa: Okokuqala, thola umthamo kanye nezinga lokushisa lento ezoshiswa, okuzonquma amandla okushisa adingekayo. Ukuphakama kwamandla okushisa, isivinini sokushisa siyashesha, kodwa futhi kudla amandla amaningi.
2. Izimfuneko zezinga lokushisa: Cacisa ngokusobala izinga lokushisa eliphezulu elidinga ukufezwa, futhi amamodeli ahlukene wamahitha anezinga lokushisa elihlukile ukuze kuqinisekiswe ukuthi i-heater ekhethiwe ingahlangabezana nezimfuneko zokushisa.
3. Isibalo samandla okushisa: Amandla okushisa angabalwa kusetshenziswa ifomula elandelayo:
Amandla okushisa=W * △ t * C * S/860 * T
Phakathi kwazo, u-W uyisisindo sesikhunta semishini (iyunithi: KG), △t umehluko wezinga lokushisa phakathi kwezinga lokushisa elidingekayo kanye nezinga lokushisa lokuqala (iyunithi:℃), u-C amandla athile okushisa (iyunithi: KJ/(kg · ℃)), S iyisici sokuphepha (emvamisa sithathwa njengo-1.2-1.5), futhi u-T yisikhathi sokushisa esidingekayo (iyunithi yehora).
Ukukhetha okubalulekile
1. Ukumelana nokugqwala: Khetha izinto ezikwazi ukumelana nokugqwala okuhle, njengensimbi engagqwali, ezifanele izikhathi ezine-acidic ne-alkaline corrosion media.
2. Ukumelana nezinga lokushisa eliphezulu: Khetha izinto ezikwazi ukumelana namazinga okushisa aphezulu, njengensimbi engagqwali noma ama-alloys akhethekile, ngokuya ngezinga lokushisa eliphezulu elifiswayo.
3. Ukusebenza kwezindleko: I-thermal conductivity ephezulu, ukumelana nokugqwala okuphezulu, nezinto zokumelana nezinga lokushisa eliphakeme ngokuvamile zinezindleko eziphakeme zokuqala, kodwa zinganikeza impilo ende yesevisi nokusebenza okuphezulu.
4. Amandla omshini: Khetha izinto ezinamandla anele okusebenza ukuze zimelane nokucindezela okubangelwa ukucindezela kokusebenza nokushintsha kwezinga lokushisa.
5. Ukusebenza kwe-insulation: Qinisekisa ukuthi impahla ekhethiwe inokusebenza okuhle kokushisa ukuze uqinisekise ukusetshenziswa okuphephile.
Lapho kukhethwa amandla nempahla yesifudumezi sepayipi likawoyela, kuyadingeka ukuthi kucutshungulwe izinto ezifana nezidingo zokushisisa, izidingo zokushisa, ukuphumelela kwezindleko, ukumelana nokugqwala, ukumelana nezinga lokushisa eliphezulu, amandla emishini, kanye nokusebenza kokushisa. Ngokucubungula lezi zici ngokugcwele, iihithalokho okulungele kakhulu isimo sohlelo lokusebenza kungakhethwa.
Uma unezidingo ezihlobene ne-heater yepayipi likawoyela, wamukelekileXhumana nathi.
