ukadaulo wa Ingiant | Makampani atsopano | Epulo 8.2025
Mu makina ambiri a mafakitale, ma slip ring induction motors akhala gwero lamphamvu la zida zambiri zolemera chifukwa cha kapangidwe kake kapadera komanso magwiridwe antchito abwino kwambiri, kupereka chithandizo chokhazikika komanso chodalirika pazinthu zosiyanasiyana zovuta kupanga. Kenako, tiyeni tifufuze kapangidwe kake, mfundo yogwirira ntchito, mawonekedwe a magwiridwe antchito, minda yogwiritsira ntchito komanso momwe ma slip ring induction motors angakulitsire mtsogolo.
Ⅰ. Chiyambi
Ma mota olowetsa mphete ya Slip-ring amachita gawo lofunika kwambiri m'mafakitale, ndipo magwiridwe antchito awo amakhudza mwachindunji magwiridwe antchito ndi kukhazikika kwa maulalo ambiri opangira. Ndikofunikira kwambiri kuti akatswiri amakampani amvetsetse chidziwitso chofunikira cha ma mota olowetsa mphete ya slip-ring.
Ⅱ. Zoyambira za Slip-Ring Induction Motor
(I) Tanthauzo ndi Mfundo
Slip-ring induction motor ndi injini yopangira mphamvu ya magawo atatu yomwe imasintha mphamvu zamagetsi kukhala mphamvu yamakina kutengera mfundo ya electromagnetic induction. Njira yake yogwirira ntchito ndikupanga mphamvu ya maginito yozungulira podutsa mphamvu yosinthira kudzera mu stator winding, yomwe imayambitsa mphamvu mu rotor winding, potero imapanga electromagnetic torque kuti iyendetse rotor kuti izungulire.
(II) Chifukwa chiyani mugwiritse ntchito mphete zopindika
Mphete zotsetsereka zimagwira ntchito yofunika kwambiri mu ma moteri olowetsa magetsi. Kumbali imodzi, ndi udindo wotumiza mphamvu zamagetsi kuchokera kuzinthu zosasuntha kupita kuzinthu zozungulira kuti zitsimikizire kuti mphamvu ikuyenda bwino; kumbali ina, polumikiza zotsutsana ndi magetsi akunja, liwiro la injini lingasinthidwe molondola kuti likwaniritse zosowa zosiyanasiyana za mafakitale osiyanasiyana.
Ⅲ. Kapangidwe ndi zigawo za injini yolowetsa mphete yotsetsereka
(I) Stator
Stator ndi kapangidwe kakunja kosasuntha ka mota, komwe ma windings amalowa mkati. Pamene ma alternating current a magawo atatu amadutsa mu ma windings awa, mphamvu ya maginito yozungulira imapangidwa, zomwe zimapangitsa kuti mota igwire ntchito.
(II) Chozungulira
Rotor ndi gawo lozungulira la mota, lokhala ndi rotor yozungulira (rotor yotsetsereka). Cholumikizira cha mphete yotsetsereka chimakhala ndi mphete zitatu zodziyimira pawokha, zomwe zimalumikizidwa ku rotor kudzera m'ma terminals ndipo zimayambitsa kutumiza mphamvu. Maburashi ndi mphete zotsetsereka zimagwira ntchito limodzi kuti zitsimikizire kuti mphamvu yodutsa ikuyenda bwino.
Ⅳ. Mfundo yogwirira ntchito ya mota yolowetsa mphete yotsetsereka
(I) Njira yogwirira ntchito mwatsatanetsatane
Pamene AC ya magawo atatu yalumikizidwa ku stator winding, stator imapanga mphamvu ya maginito yozungulira. Malinga ndi mfundo ya induction ya electromagnetic, mphamvu ya maginito iyi imayambitsa mphamvu mu rotor winding. Mphete yotsetsereka ndi burashi zimatumiza mphamvu kuchokera ku stator kupita ku rotor winding, ndikupanga electromagnetic torque, kuyendetsa rotor kuti izungulire, ndikuzindikira kusintha kwa mphamvu yamagetsi kukhala mphamvu yamakina.
(II) Udindo waukulu wa "kutsetsereka"
"Kutsetsereka" kumatanthauza kusiyana pakati pa liwiro la mphamvu ya maginito yozungulira ndi liwiro lenileni la rotor, lomwe ndi chinthu chofunikira kwambiri pakugwira ntchito kwa mota. Kukhalapo kwa kutsetsereka kumapangitsa kuti rotor winding ipangitse mphamvu yamagetsi, zomwe zimapangitsa kuti mota igwire ntchito mosalekeza. Mwa kusintha kukana kwakunja kolumikizidwa ndi dera la rotor, kutsetsereka kumatha kusinthidwa mosavuta kuti kukwaniritse kuwongolera kolondola kwa liwiro la mota ndi torque.
Ⅴ. Kuwongolera liwiro la mota yolowetsa mphete yotsetsereka
(I) Mfundo yoyendetsera liwiro
Kuwongolera liwiro la injini ya Slip-ring induction kumadalira kwambiri kusintha kutsetsereka. Kusintha kukana kwakunja kwa rotor kumatha kuwongolera bwino kutsetsereka, motero kukwaniritsa kusintha kolondola kwa liwiro la injini kuti ikwaniritse zofunikira za liwiro la ntchito zosiyanasiyana zamafakitale.

2. Voltage ndi ma frequency: Ngakhale kusintha kwa voltage ndi ma frequency a stator winding kungakhudze liwiro la mota, kungayambitse kusakhazikika kwa torque ndi kuchepetsa mphamvu, ndipo sikugwiritsidwa ntchito kawirikawiri pa ntchito zenizeni. Mu makina osinthasintha a frequency drive, kuwongolera molondola kwa voltage ndi frequency ratio kungapangitse zotsatira zabwino zowongolera liwiro.
3. Kusintha kwa nambala ya pole: Kusintha chiwerengero cha pole kumasintha liwiro logwirizana. Mu ma motors opangidwa mwapadera okhala ndi liwiro lawiri kapena la multi-speed slip-ring induction, kusintha kwa nambala ya pole kumachitika kudzera mu kasinthidwe ka stator winding kuti asinthe liwiro la mota. Njirayi ili ndi kukhazikika kwakukulu komanso magwiridwe antchito, koma pali njira zochepa zowongolera liwiro.
4. Mphamvu yonyamula katundu: Liwiro la injini limasintha ndi mphamvu yonyamula katundu. Mphamvu yonyamula katundu ikawonjezeka, liwiro la injini limachepa; mphamvu yonyamula katundu ikachepa, liwiro la injini limawonjezeka. Mu ntchito zenizeni, mphamvu ya injini ndi kasinthidwe kake ziyenera kusankhidwa moyenera malinga ndi makhalidwe a katundu kuti zitsimikizire kuti ntchito yake ndi yokhazikika.
VI. Ubwino ndi kugwiritsa ntchito ma motors olowetsa mphete yotsetsereka m'makampani
(I) Ubwino wa ntchito zamafakitale
1. Mphamvu yoyambira yapamwamba: Poyambira, imatha kupanga mphamvu yoyambira yapamwamba yokhala ndi mphamvu yoyambira yochepa, yomwe ndi yoyenera zida zoyambira zolemera monga makina amigodi ndi ma crane olemera.
2. Kuwongolera liwiro losinthasintha: Mwa kusintha choletsa chakunja, liwiro la injini limatha kusinthidwa mosavuta kuti likwaniritse zosowa za njira zosiyanasiyana zopangira.
3. Mphamvu yayikulu: Kuwonjezera kukana kwa rotor circuit kungathandize kuti mphamvu ya injini igwire bwino ntchito, kuchepetsa kutaya mphamvu yogwira ntchito, komanso kupititsa patsogolo kugwiritsa ntchito mphamvu moyenera. Ndi yoyenera zida zazikulu zamafakitale zomwe zimafunikira mphamvu zambiri.
4. Kapangidwe kolimba komanso kolimba: Kapangidwe kolimba ka kapangidwe kake kamalimbana kwambiri ndi mphamvu zamagetsi ndi makina, ndipo kamatha kugwira ntchito mokhazikika kwa nthawi yayitali m'malo ovuta a mafakitale.
5. Sinthani kuti zigwirizane ndi kusintha kwa katundu: Makhalidwe a liwiro ndi mphamvu ya galimoto amatha kusinthidwa okha malinga ndi zofunikira pa katundu, ndipo amatha kugwira ntchito bwino pansi pa zinthu zopepuka komanso zolemera.
(II) Milandu yogwiritsira ntchito mafakitale
1. Makampani a zitsulo ndi migodi:Mu mgodi waukulu wamkuwa, chopukusira chimayenera kuswa miyala yayikulu m'zidutswa zazing'ono.
