Posankha a pafupipafupi zida zotenthetsera induction , m’pofunika kuwerengera?
Kusankhidwa kwa mafupipafupi amakono makamaka kusankha maulendo afupipafupi, ndiko kuti, kusankha gulu lafupipafupi, osati kusankha molondola mtengo wafupipafupi, ndizopanda tanthauzo. Ziyenera kunenedwa kuti 8kHz ndi 10kHz ndizofanana; 25kHz ndi 3kHz zitha kugwiritsidwanso ntchito mofanana; koma 8kHz ndi 30kHz, 30kHz ndi 250kHz sangagwiritsidwe ntchito mofanana, chifukwa sali mu gulu lafupipafupi, pali dongosolo la kusiyana kwakukulu.
Kuchulukira kwa zida zamagetsi zothamanga kwambiri komanso zapakati-pafupipafupi zavotera ma frequency amayiko onse. Malingana ndi zofunikira za kukula kwa magawo osiyanasiyana ndi kuya kwa wosanjikiza wouma, maulendo oyenerera amatha kusankhidwa malinga ndi Table 2-1 ndi Table 2.2.
Table 2-1 Wowuma wosanjikiza kuzama kwa mtengo wanthawi zonse
Mafupipafupi / kHz | 250 | 70 | 35 | 8 | 2. 5 | 1. 0 | 0.5 | |
Kuzama kwa wosanjikiza / mm | Wamng’ono kwambiri | 0. 3 | 0. 5 | 0. 7 | 1. 3 | 2.4 | 3.6 | 5. 5 |
pazipita | 1.0 | 1.9 | 2.6 | 5. 5 | 10 | 15 | makumi awiri ndimphambu ziwiri | |
mulingo woyenera | 0. 5 | 1 | 1.3 | 2.7 | 5 | 8 | 11 |
① Pa 250kHz , chifukwa cha kutentha kwachangu kwambiri, deta yeniyeni ikhoza kukhala yaikulu kuposa mtengo wa tebulo.
Table 2-2 Kusankhidwa kwa mafupipafupi panthawi ya kuzimitsidwa kwa cylindrical mbali

Table 2-3 ndi tchati chaposachedwa chosankha mafupipafupi panthawi yowumitsidwa kwa magawo a John Deere Company ku United States. Kutalika kwa gawo ndi kuya kwa wosanjikiza wowumitsidwa zaphatikizidwa, ndipo zitha kugwiritsidwanso ntchito ngati tchati chofotokozera pakusankha pafupipafupi.
Table 2-3 Kusankhidwa kwa ma frequency apano a magawo owumitsidwa

Zindikirani: 1. Kuzama kwazitsulo zowuma patebulo kumatengedwa kuchokera kuzitsulo zotentha zapakati pa carbon, ndipo kuya kwazitsulo zolimba zimayesedwa mpaka 45HRC.
2. The osachepera anaumitsa wosanjikiza kuya zimadalira katundu katundu wa Kutentha kwa nthawi yochepa (chisanadze kutentha boma mankhwala), ndi pazipita anaumitsa wosanjikiza kuya zimadalira hardness wa zinthu ndi mlingo wa kutenthedwa pamwamba.
3. A imayimira ma frequency oyenera kwambiri; B imayimira mafupipafupi oyenera; C imayimira ma frequency ocheperako.
