Zoyenera kuchita ngati ma frequency apamwamba zida zotentha ali ndi overcurrent

Choyamba, fotokozani momveka bwino kuti malingaliro a mapangidwe a makina otenthetsera othamanga kwambiri a Tongcheng, popeza dongosolo la alamu lapangidwa, liyenera kukhala ndi tanthauzo lake ndi mtengo wake. Poyambira chenjezo la dongosololi ndikuti,

A. Zikuwonetsa kuti zalephera, chonde siyani makinawo mwachangu momwe mungathere kuti muthetse mavuto.

B. Fotokozerani vutolo, mutha kudziwa mwachangu malo a vutolo, ndikupereka chithandizo pakukonza. Chifukwa chake, alamu ikachitika, chonde siyani makinawo kuti awonedwe ndikuwongolera nthawi kuti mupewe kuwonongeka kwakukulu.

Zifukwa za overcurrent:

Coil yodzipangira yokha ili ndi mawonekedwe olakwika ndi kukula kwake, mtunda pakati pa chogwirira ntchito ndi coil induction ndi yaying’ono kwambiri, pali kagawo kakang’ono pakati pa chogwirira ntchito ndi coil induction kapena coil induction palokha, ndipo koyilo yokonzekera induction imakhudzidwa. ndi kasitomala zitsulo fixture pa ntchito kapena pafupi izo. Mphamvu ya zinthu zachitsulo, etc.

Njira:

1. Panganinso koyilo yolowera, kusiyana pakati pa koyilo yolowera ndi gawo lotenthetsera liyenera kukhala 1-3mm (pamene malo otentha ndi ochepa)

Ndikoyenera kugwiritsa ntchito chubu chamkuwa chozungulira kapena chubu chamkuwa chokhala ndi makulidwe a 1-1.5mm ndi pamwamba pa φ5 ​​kuwongolera koyilo yolowera.

2. Kuthetsa dera lalifupi ndi kuyatsa kwa coil induction

3. Zida zokhala ndi maginito osakwanira bwino monga mkuwa ndi aluminiyamu zikatenthedwa, kuchuluka kwa ma koyilo olowera kumayenera kuonjezedwa.

4. Zidazi zipewe kuwala kwa dzuwa, mvula, chinyezi, ndi zina.

Onani ngati mphamvu yotenthetsera ikufanana ndi chitetezo. Ngati machesi ali olondola, onani ngati ntchitoyo ndi yolondola, makamaka nthawi yotentha.

5. Sinthani ku chotchinga chachikulu chachitetezo, pokhapokha ngati chowotcha chimakhala chabwinobwino

C. Kuyamba mochulukira: Zifukwa zambiri ndi:

1. Kuwonongeka kwa IGBT

2. Kulephera kwa board board

3. Zimayambitsidwa ndi kulinganiza mphete zazing’ono zamaginito

4. Bwalo lozungulira ndilonyowa

5. Mphamvu yamagetsi ya board board ndi yachilendo

6. Dera lalifupi la sensa

Njira:

1. Bwezerani dalaivala bolodi ndi IGBT, chotsani mphete yaing’ono ya maginito kuchokera kutsogolo, yang’anani njira yamadzi, ngati bokosi lamadzi latsekedwa, kuwombera bolodi logwiritsidwa ntchito ndi chowumitsira tsitsi, ndikuyesa magetsi.

2. Overcurrent pambuyo ntchito kwa nthawi pambuyo booting: chifukwa zambiri osauka kutentha dissipation wa dalaivala. Njira yothandizira: perekaninso mafuta a silicone; onani ngati njira yamadzi yatsekedwa.

D. Kuwonjezeka kwa mphamvu kuposa panopa:

(1) Kuyatsa kwa Transformer

(2) Katswiriyu sikufanana

(3) Kulephera kwa board board

Njira:

1. Mkati mwa makina ndi coil induction ayenera kuziziritsidwa ndi madzi, ndipo gwero la madzi liyenera kukhala loyera, kuti lisatseke chitoliro chozizira ndikupangitsa makinawo kutenthedwa ndi kuwonongeka.

Kutentha kwa madzi ozizira sikuyenera kukhala kokwera kwambiri, kuyenera kukhala kotsika kuposa 45 ℃.

2. Osagwiritsa ntchito tepi yazinthu zosalowa madzi mukayika koyilo yolowera kuti mupewe kulumikizidwa koyipa kwamagetsi

Osasintha ma coil soldering kukhala brazing kapena siliva soldering!

3. Pali zifukwa zambiri zokhudzira kuchuluka kwa kutembenuka kwa koyilo yolowera pakali pano, komanso kumayambitsa kuchulukirachulukira.

Choyamba, zimagwirizana ndi zinthu za workpiece;

Kachiwiri, ngati koyiloyo ndi yayikulu kwambiri, yapano idzakhalanso yaying’ono;

Apanso, koyiloyo ndi yaying’ono kwambiri, kuchuluka kwa kutembenuza koyilo kumakhala kocheperako.
