Kusiyanitsa kwapakati pa kuzimitsa kwapafupipafupi, kuzimitsa kwapafupipafupi ndi zida zamakono zotseketsa pafupipafupi
Kusiyanitsa pakati pa kuzimitsa kwapafupipafupi, Kuthetsa pafupipafupi ndi zida zamakono zotseketsa pafupipafupi
Zipangizo zopangira zitsulo zimafunika kuzimitsidwa ndi kutentha. Zida zolimbitsa induction tsopano ndi njira yotchuka kwambiri kwa opanga. Malinga ndi kuchuluka kwa zida, zimatha kugawidwa kukhala zida zowumitsa pafupipafupi, zida zolimbitsa pafupipafupi komanso zida zowumitsa pafupipafupi. Mukamagula, wina amafunikira zida zotsekemera zapafupipafupi, anthu ena amafunikira zida zotsekera pafupipafupi, anthu ena amafunikira zida zamakono zotsekera pafupipafupi, zomwe zimatengera makulidwe azitsulo zomwe zimafunidwa ndi cholembedwacho.
Ngakhale zida zolimbitsa pafupipafupi, zida zolimbitsa pakatikati komanso zida zolimbitsa kwambiri ndizosiyana kwambiri, mfundo zawo zogwirira ntchito ndizofanana. Onsewo amagwiritsa ntchito pafupipafupi kuti atenthe msanga kutentha ndikuzizira pazitsulo. Ndiye kuti, kudzera pakulowetsa kwa pafupipafupi kwamasinthidwe ena aposachedwa, mafupipafupi omwewo a maginito osinthasintha amapangidwa mkati ndi kunja kwa koyilo. Ngati chojambuliracho chikayikidwa pa coil, chojambuliracho chidzakopeka ndikusintha kwamakono ndikuwotchera ntchito.
Kulowetsa kwaposachedwa kwazakuya kwa chojambulira chogwirira ntchito kumadalira pafupipafupi (nyengo pamphindikati). Kutalika kwafupipafupi, kutsika kwakanthawi kolowera, ndikocheperako. Chifukwa chake, ndizotheka kusankha mafupipafupi osiyanasiyana kuti mukwaniritse zosanjikiza zolimba zakuya, ndichifukwa chake anthu ena amasankha zida zotsekera pafupipafupi, ena amasankha zida zotsekera pafupipafupi, ndipo anthu ena amasankha zida zapamwamba zotulutsa mawu. Tiyeni tikambirane za kuumitsa kwapafupipafupi, kuumitsa kwapakatikati komanso zida zowumitsa kwambiri.
1. Zida zotsekera kwambiri ndi 50-500KHz, wosanjikiza wolimba (1.5-2mm), pafupipafupi zolimba, chogwirira ntchito sikophweka kuyikiritsa, kupunduka, kuzimitsa mtundu, kupanga bwino kwambiri, zida zamtunduwu ndizoyenera kukangana , monga mtundu wa pinion, shaft (wa 45 # chitsulo, 40Cr chitsulo).
2. Chida chothanirana pafupipafupi cha 30-36kHz, cholimba (1.5-3mm). Wosanjikiza wolimba amatha kugawidwa pamizere yantchitoyo. Chithandizo cha kutentha kwapamwamba pama modulus gear ndikutenga kulimba kwambiri kwa martensite posintha mawonekedwe a gawolo, kwinaku mukusunga kulimba ndi kupindika kwa maziko (mwachitsanzo, kuzimitsa malo), kapena kusintha mawonekedwe am’madzi nthawi yomweyo kupeza kukana dzimbiri, kukana asidi, kukana soda, ndi kuwuma kwapamwamba kuposa njira yakale (mwachitsanzo, mankhwala othandizira kutentha).
3. Makina azimitse pafupipafupi ndi 1-10KHz komanso pafupipafupi pazakuuma kolimba (3-5mm). Zipangizo zamtunduwu ndizoyenera kutengera ziwalo, monga ma crankshafts, magiya akulu, katundu wambiri, makina opera makina, ndi zina zambiri (izi ndizitsulo 45, 40Cr Steel, 9Mn2V ndi ductile iron).
Kusankha zida zotsekera mu band frequency kumatsimikizidwa ndi kasitomala, ndipo kusankha kwa malonda kumatsimikizidwanso ndi kasitomala. Zida zotsekera zamagulu angapo amtunduwu zimatsimikizika ndi chozimitsira chomwe chazimitsidwa. Makasitomala amafunika kusiyanitsa pakati pa malonda ndi kusankha wopanga wodalirika komanso wodalirika. Zogulitsa zitha kupangitsa kuti ntchito yawo ikhale yothandiza kwambiri.
