Kube yisivumelwano sokukhetha ama-forklift kagesi ezimeni eziningi zomsebenzi ezinezidingo eziphakeme zemvelo.I-forklift kagesi ukusetshenziswa kwebhethri ukunikeza amandla ku-forklift, yi-motor izoguqulwa ibe amandla omshini.Okokuqala, i-forklift kagesi ngokuvamile inamamotha amathathu, okuyimoto ehambayo, ephakamisayo nemoto yokuqondisa.Isistimu yokushayela ye-motor ehambayo ekugcineni inikeza i-torque yokushayela esondweni.I-motor ephakamisayo ishayela ngokuqondile i-lifting system hydraulic pump, Ishayela uhlelo oluphakamisayo lwe-hydraulic, kuyilapho injini yokuqondisa isetshenziselwa ukushayela iphampu yokuqondisa ku-forklift kagesi nge-hydraulic steering egcwele.Ngokuthuthukiswa kwesistimu ye-hydraulic, i-motor ephakamisayo kanye ne-steering motor ivame ukuhlanganiswa kuma-forklift kagesi asezingeni eliphezulu.
Okubizwa ngokuthi i-DC forklift, ibhekisela ekuphakamiseni nasekuhambeni zisebenzisa i-DC motor, bese i-AC forklift isebenzisa ama-AC motors ukuphakamisa nokuhamba.
Ukuze silungise umehluko, sithola ukwakheka kanye nemodi yokusebenza ye-AC motor (izigaba ezintathu ze-AC induction motor) kanye ne-DC motor.Izimiso ze-DC motor kanye ne-AC motor zihlukile, futhi izakhiwo zazo nazo zihlukile.Ngamandla afanayo, usayizi wangaphandle we-DC motor mkhulu kune-AC motor, ngoba injini ye-DC idinga isikhala esiningi ukuze ifake i-commutator ne-carbon brush.Emotweni ye-DC, ama-magnets ahlala njalo afakwe kumakhoyili avusa amadlingozi we-stator, futhi ama-windings we-armature afakwe ku-rotor.Njengoba i-rotor ijikeleza, i-DC current ihlale igeleza ngebhulashi lekhabhoni, eligcina ukuxhumana okuseduze nomuntu ohambayo, okubangela ukungqubuzana.Uma amandla ebhethri enganele noma i-current ye-forklift ekhuphukayo yemoto yanda, ukushisa komhambisi kuzokwanda, okubangela ukuguga nokwehluleka kwebhulashi.
Izici zemoto ye-DC zinqunywa i-voltage ephumayo yesilawuli, ngakho-ke lapho ibhethri liphansi, izici zokukhishwa kwemoto zizoshintsha.Isilawuli se-Dc motor iyisisetshenziswa esishintshashintshayo esinamandla aphezulu (okufana ne-MOSFET) esakhiwe yisekethe ye-H-bridge, sisebenzisa ubuchwepheshe be-PWM pulse-width modulation, ngokushintsha isilinganiso somsebenzi we-algorithm yokulawula i-chopper, ukulungisa isivinini nokusheshisa. ye-dc motor.Ibanga lesivinini linobubanzi obuthile.Ngenxa yobuchwepheshe bokulawula obuvuthiwe bemoto ye-DC, maningi ama-Oem futhi azimisele ukusebenzisa isilawuli sikagesi se-DC.
Ngakho-ke, umehluko omkhulu phakathi kwesistimu ye-AC nohlelo lwe-DC umi kanje:
1. I-Dc motor idinga ukufakwa negiya lokuqondisa kanye ne-carbon brush.Ngenxa yethonya losayizi, inkululeko yokuklama imoto ingaphansi kwaleyo ye-AC motor;
2. I-carbon brush ye-dc motor iyingxenye egqokekayo, edinga ukunakekelwa, okuholela ezindlekweni zesikhathi kanye nezindleko zomnotho;
3. Isistimu ye-Dc ithintwa kakhulu amandla ebhethri namandla okukhuphuka, futhi ukwanda kwamanje kuzoletha izinguquko ezihambisanayo ekusebenzeni.Ngaphansi komthamo webhethri ofanayo, isistimu ye-ac izosebenzisa isikhathi eside;
4. Izingxenye ezinyakazayo ze-DC motor, ukungqubuzana kwemishini kukhiqiza ukushisa okukhulu, ukushisa okukhiqizwa ukugoqa kwe-armature ku-rotor akukwazi ukukhishwa emoyeni ngesikhathi, kuletha ushintsho lomthamo wokugcwala;
5. Ibanga lejubane le-AC motor libanzi kune-dc motor enamandla afanayo, ukuguquguquka okungcono;
6. Uhlelo lwe-AC lungafinyelela ukuvuselelwa kwamandla ngokuphumelelayo.Amandla angasebenzi akhiqizwe i-forklift ashajwa kabusha ebhethrini, okunweba isikhathi sesevisi yeshift eyodwa nempilo yesevisi yebhethri.
7. I-algorithm yokulawula ye-DC motor ivuthiwe futhi ilula, futhi intengo yokulawula kagesi ye-DC izokwehliswa ngokufanele.
Ngamafuphi, uhlelo lwe-AC drive luzosetshenziswa kabanzi njengobuchwepheshe bokuthuthukisa iloli ye-forklift.Lokhu kubizwa ngokuthi "ubuchwepheshe obuguqukayo be-forklift kagesi ngekhulu lama-21", okuzoba nomthelela othile ezingeni lobuchwepheshe, ukuthengiswa komkhiqizo, isabelo semakethe, inzuzo kanye nesithombe sokusungulwa kwamabhizinisi e-forklift.Phela ukuncintisana kwekusasa kuzobe kumayelana nobuchwepheshe.
I-Taizhou Kylinge Technology Co., LTD., enobuchwepheshe obuphambili bokukhiqiza, inqubo yokukhiqiza emihle ukukulethela imikhiqizo esezingeni elingcono kakhulu, wamukelekile amakhasimende ekhaya naphesheya
xoxisana!
