Momwe mungasankhire machitidwe a DC ndi AC a forklift yamagetsi, ndipo pali kusiyana kotani pakati pawo?

Zakhala mgwirizano wosankha ma forklift amagetsi m'magawo ambiri ogwira ntchito omwe ali ndi zofunikira zapamwamba zachilengedwe.Forklift yamagetsi ndikugwiritsa ntchito batri kuti ipereke mphamvu ku forklift, ndi mota imasinthidwa kukhala mphamvu yamakina.Choyamba, forklift yamagetsi nthawi zambiri imakhala ndi ma mota atatu, omwe ndi mota yoyenda, mota yokweza ndi chiwongolero.Njira yoyendetsera galimoto yoyendetsa galimoto pamapeto pake imapereka torque yoyendetsera gudumu.Galimoto yokweza imayendetsa molunjika pampu yamagetsi yama hydraulic, Imayendetsa makina okweza ma hydraulic, pomwe chowongolera chimagwiritsidwa ntchito kuyendetsa mpope wowongolera mu forklift yamagetsi yokhala ndi chiwongolero chonse cha hydraulic.Ndikusintha kwa ma hydraulic system, mota yonyamula ndi chiwongolero nthawi zambiri imaphatikizidwa muzowongolera zamagetsi zama forklift.

Otchedwa DC forklift, amatanthauza kukweza ndi kuyenda akugwiritsa ntchito DC motor, ndiye AC forklift ntchito AC motors kukweza ndi kuyenda.

Kuti tipeze kusiyanako, timapeza mawonekedwe ndi magwiridwe antchito a AC motor (magawo atatu AC induction motor) ndi DC motor.Mfundo za mota ya DC ndi mota ya AC ndizosiyana, ndipo mawonekedwe ake ndi osiyana.Mphamvu yomweyo, kukula kwakunja kwa mota ya DC ndikokulirapo kuposa mota ya AC, chifukwa mota ya DC imafunikira malo ochulukirapo kuti muyike cholumikizira ndi burashi ya kaboni.Mu mota ya DC, maginito okhazikika amayikidwa muzokopa za stator, ndipo ma windings a armature amayikidwa pa rotor.Pamene rotor imazungulira, magetsi a DC nthawi zonse amayenda kudzera mu burashi ya kaboni, yomwe imayandikira pafupi ndi commutator, zomwe zimayambitsa mikangano.Mphamvu ya batri ikakhala yosakwanira kapena mphamvu yamagetsi yokwera ya forklift ikuwonjezeka, kutentha kwa commutator kumawonjezeka, zomwe zimapangitsa kuti burashi iwonongeke.

Makhalidwe a mota ya DC amatsimikiziridwa ndi voteji yotulutsa chowongolera, kotero batire ikatsika, mawonekedwe agalimoto amasintha.Dc motor controller ndi chipangizo champhamvu kwambiri chosinthira pafupipafupi (monga MOSFET) chopangidwa ndi H-bridge circuit, pogwiritsa ntchito ukadaulo wa PWM pulse-width modulation, posintha kuchuluka kwa ntchito ya chopper control algorithm, kusintha liwiro ndi mathamangitsidwe. dc motere.Liwiro la liwiro lili ndi mulingo winawake.Chifukwa chaukadaulo wowongolera wamagetsi a DC, palinso ma Oem ambiri omwe amafunitsitsa kugwiritsa ntchito magetsi a DC.

Chifukwa chake, kusiyana kwakukulu pakati pa AC system ndi DC system ndi motere:

1. Dc motor iyenera kuyikidwa ndi zida zowongolera ndi burashi ya kaboni.Chifukwa cha chikoka cha kukula, ufulu wa mapangidwe a galimoto ndi wocheperapo kuposa wa AC motor;

2. Burashi ya kaboni ya dc motor ndi gawo lovala, lomwe limayenera kusamalidwa, zomwe zimapangitsa kuti pakhale mtengo wanthawi komanso mtengo wachuma;

3. Dc dongosolo limakhudzidwa kwambiri ndi mphamvu ya batri ndi mphamvu yokwera, ndipo kuwonjezeka kwamakono kudzabweretsa kusintha kofanana ndi ntchito.Pansi pa batire yomweyi, ac system idzagwiritsa ntchito nthawi yayitali;

4. DC motor kusuntha mbali kwambiri, makina mikangano umatulutsa kutentha kwambiri, kutentha kwaiye ndi armature mapiringidzo pa rotor sangathe mwachindunji zinatuluka mu mlengalenga mu nthawi, kubweretsa kusintha mphamvu mochulukira;

5. AC galimoto liwiro osiyanasiyana ndi lonse kuposa galimoto DC ndi mphamvu yomweyo, kusinthasintha bwino;

6. Dongosolo la AC likhoza kukwaniritsa kusinthika kwa mphamvu bwino.Mphamvu ya inertial yomwe imapangidwa ndi forklift imalowetsedwa mu batri, zomwe zimatalikitsa nthawi yautumiki wamtundu umodzi komanso moyo wantchito wa batri.

7. Dongosolo lowongolera la DC mota ndi lokhwima komanso losavuta, ndipo mtengo wamagetsi a DC udzachepetsedwa moyenerera.

Mwachidule, AC drive system idzagwiritsidwa ntchito mochulukirachulukira ngati ukadaulo wokweza wamagalimoto a forklift.Izi zimatchedwa "teknoloji yosinthika ya forklift yamagetsi m'zaka za zana la 21", zomwe zidzakhudza kwambiri luso lamakono, malonda a malonda, gawo la msika, phindu komanso chithunzi cha zatsopano zamabizinesi a forklift.Pambuyo pake, mpikisano wamtsogolo udzakhala wokhudzana ndi zamakono.
