Ndikusintha kosalekeza kwa zofunikira zamakampani pakuwongolera liwiro la crane, njira zachikhalidwe zoyendetsera liwiro la crane monga kuwongolera liwiro la rotor asynchronous motor rotor resistance regulation, thyristor stator voltage regulation regulation and cascade speed regulation zili ndi izi: yokhotakhota asynchronous motor ili ndi mphete zosonkhanitsa ndi maburashi, zomwe zimafunika kukonzedwa pafupipafupi. Zolephera zomwe zimachitika chifukwa cha mphete zosonkhanitsa ndi maburashi ndizofala kwambiri. Kuphatikiza apo, kugwiritsa ntchito kuchuluka kwa ma relay ndi ma contactor kumapangitsa kuti pakhale kukonza kwakukulu pamalopo, kulephera kwakukulu kwa dongosolo lowongolera liwiro, komanso zizindikiro zosakwanira bwino zamakina owongolera liwiro, zomwe sizingakwaniritsenso. zofunikira zapadera zopangira mafakitale.
Kugwiritsiridwa ntchito kwakukulu kwa ukadaulo wa AC variable frequency regulation m'mafakitale kumapereka njira yatsopano yoyendetsera liwiro lalikulu komanso lapamwamba la ma cranes oyendetsedwa ndi ma AC asynchronous motors. Ili ndi zizindikiro zoyendetsera liwiro lapamwamba kwambiri, imatha kugwiritsa ntchito ma motors a asynchronous cage agologolo okhala ndi mawonekedwe osavuta, odalirika ogwiritsira ntchito komanso kukonza bwino, ndipo ndi othandiza komanso opulumutsa mphamvu. Dongosolo lake loyang'anira zotumphukira ndi losavuta, ntchito yokonza ndi yaying'ono, ntchito zoteteza ndi kuyang'anira zatha, ndipo kudalirika kwa magwiridwe antchito kumakhala bwino kwambiri poyerekeza ndi dongosolo lakale la AC. Chifukwa chake, kugwiritsa ntchito ma AC ma frequency frequency regulation ndiye gawo lalikulu pakukula kwaukadaulo wowongolera liwiro la crane AC.
Ukadaulo wowongolera liwiro la AC ukagwiritsidwa ntchito pama cranes, poyerekeza ndi njira yanthawi yayitali yoyendera ma asynchronous motor rotor resistance regulation system yomwe imagwiritsidwa ntchito kwambiri pamsika, imatha kubweretsa zotsatirazi pazachuma komanso chitetezo ndi kudalirika:
(1) Ma Crane omwe amagwiritsa ntchito ukadaulo wa AC variable frequency regulation ali ndi mwayi wokhazikika bwino chifukwa cha mawonekedwe amakina agalimoto yoyendetsedwa ndi ma frequency converter, ndipo sadzakhala ndi chodabwitsa choti liwiro lagalimoto limasintha ndi katundu wa cranes zachikhalidwe, zomwe imatha kupititsa patsogolo ntchito zotsitsa ndi zotsitsa.
(2) The variable frequency crane imayenda bwino, imayamba ndi mabuleki bwino, ndipo kugwedezeka ndi kukhudzidwa kwa makina onse kumachepetsedwa kwambiri pakuthamanga komanso kutsika panthawi yogwira ntchito, zomwe zimapangitsa chitetezo ndikuwonjezera moyo wa zida zamakina.
(3) Kuphulika kwamagetsi kumayendetsedwa pamene galimoto ili pa liwiro lotsika, ndipo kuphulika kwa mbedza yaikulu ndi trolley kumatsirizidwa ndi kuphulika kwa magetsi, kotero kuti moyo wa brake pad wa brake wamakina umakulitsidwa kwambiri ndipo mtengo wokonza umachepetsedwa. .
(4) The gologolo khola asynchronous galimoto ndi dongosolo losavuta ndi kudalirika mkulu ntchito m'malo mapiringidzo rotor asynchronous galimoto, kupewa kulephera kwa galimoto kuwonongeka kapena kulephera kuyamba chifukwa cha kukhudzana osauka chifukwa kuvala kapena dzimbiri wa wokhometsa mphete ndi burashi. .
(5) Chiwerengero cha contactors AC kwambiri yafupika, ndi dera lalikulu la galimoto akwaniritsa kulamulira contactless, kupewa kuwotcha contactor kukhudzana chifukwa cha ntchito pafupipafupi ndi kuwonongeka kwa galimoto chifukwa cha kuyaka kwa contactor kulankhula.
(6) Dongosolo la AC variable frequency regulation system limatha kusintha mwachangu liwiro la giya lililonse komanso kuthamangitsa ndi kutsika nthawi malinga ndi momwe malo alili, kupangitsa kuti crane yosinthika ikhale yosinthika kuti igwire ntchito ndikukhala ndi kusinthika kwabwino pamalopo.
(7) The AC variable frequency speed regulation system ndi njira yoyendetsera liwiro lapamwamba kwambiri yogwira ntchito bwino komanso kuchepa kwa kutentha pang'ono, kotero imapulumutsa magetsi ambiri poyerekeza ndi dongosolo lakale loyendetsa liwiro.
(8) Wotembenuza pafupipafupi amakhala ndi chitetezo chokwanira, kuyang'anira ndi kudzidziwitsa okha ntchito. Zikaphatikizidwa ndi kuwongolera kwa PLC, zitha kusintha kwambiri kudalirika kwa makina owongolera amagetsi amtundu wamagetsi.
