Poyerekeza ndi ma asynchronous motors, maginito okhazikika a synchronous motors ali ndi zabwino zoonekeratu. Ali ndi mphamvu zambiri, mphamvu zambiri, zizindikiro zogwira ntchito bwino, kukula kochepa, kulemera kochepa, kutentha kochepa, kukwera kwakukulu, zotsatira zaumisiri,

Pazinthu zamagalimoto, mbali imodzi, makasitomala ayenera kudziwitsidwa za kukonza ndi kusamalira zinthu panthawi yagalimoto pogwiritsa ntchito njira zoyenera; kumbali ina, chidziwitso ndi nzeru ziyenera kusonkhanitsa mosalekeza.

Kulowetsa bizinesi:
Ku UAE, makampani akuyenera kukwaniritsa izi kuti alowetse katundu:
1. Kulembetsa kampani: Choyamba, kampaniyo iyenera kulembetsa ndi UAE Business Registry ndikupeza chilolezo chovomerezeka chabizinesi.
2. Kulembetsa kwa kasitomu: Kenako, kampaniyo ikuyenera kulembetsa ndi UAE Federal Customs Authority (FCA) ndikupeza khodi yotengera katundu,
3. Zilolezo zoyenera: Pamitundu ina ya katundu (mwachitsanzo, chakudya, mankhwala, zodzoladzola, ndi zina zotero), chivomerezo kapena chilolezo kuchokera kunthambi za boma ziyenera kupezedwa kale.

Mitundu ndi mawonekedwe a ma couplings

1. Kulumikizana kolimba:
• Zomwe Zilipo: Palibe kusuntha pakati pa ma shafts omwe amaloledwa, oyenera pazochitika zomwe ma shafts awiriwa ali ndi kugwirizanitsa bwino.
•Mitundu: kuphatikiza zomangira manja, zomangira zingwe, zolumikizira za flange, ndi zina.

Shaft current ndivuto lodziwika bwino komanso losapeŵeka kwa ma motors okwera kwambiri komanso ma frequency frequency motors. Shaft yapano imatha kuwononga kwambiri makina onyamula agalimoto. Pazifukwa izi, opanga magalimoto ambiri amagwiritsa ntchito njira zotsekera zotchingira kapena njira zodutsamo kuti apewe zovuta zomwe zikuchitika.

Mipiringidzo yopyapyala kapena mipiringidzo yosweka nthawi zambiri imagwiritsidwa ntchito molakwika pama injini opangira aluminiyamu. Mipiringidzo yonse yopyapyala ndi mipiringidzo yosweka imatanthawuza mipiringidzo ya rotor. Mwachidziwitso, pomwe mawonekedwe a rotor akukhomerera, kutalika kwachitsulo, ndi malo otsetsereka atsimikiziridwa, mipiringidzo ya rotor imafotokozedwa mokhazikika. Komabe, pakupanga kwenikweni, zifukwa zosiyanasiyana nthawi zambiri zimapangitsa kuti mipiringidzo yomaliza ya rotor ikhale yopotoka komanso yopunduka, ndipo ngakhale mabowo ochepera amawonekera mkati mwa mipiringidzo. Pazovuta kwambiri, mipiringidzo imatha kusweka.

Kukhazikika ndi kuwongolera kwa magwiridwe antchito amagalimoto ndi chifukwa cha kuchuluka kwa mapangidwe kumbali imodzi, ndipo kukwaniritsidwa kwa kapangidwe kazinthu kudzera munjira yopangira ndikofunikira kwambiri kumbali ina. Makamaka pankhani yolimba mkati mwa ma motors ena, ndikofunikira kuti pakhale mikhalidwe yofunikira ya kutchinjiriza kwamagetsi ndi mpweya wabwino komanso kutulutsa kutentha pakugwira ntchito kwagalimoto.

Mfundo zotsatirazi ziyenera kuganiziridwa posankha mapeto okhazikika a chithandizo cha galimoto (chomwe chimatchedwa kuti mapeto okhazikika): (1) zofunikira zowongolera molondola pazida zoyendetsedwa; (2) chikhalidwe cha katundu woyendetsedwa ndi galimoto; (3) kunyamula kapena kuphatikizika koyenera kuyenera kupirira mphamvu inayake ya axial. Kutengera zinthu zitatu zomwe tafotokozazi, mayendedwe a mpira wakuya amagwiritsidwa ntchito nthawi zambiri ngati chisankho choyamba pamagalimoto ang'onoang'ono ndi apakatikati.

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 mozungulira asynchronous mota ili ndi mphete zosonkhanitsa ndi maburashi, zomwe zimafunikira 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.
