Umshini wokupakisha ifilimu owelula wohlelo lokulawula kagesi lwe-DC motor

Ifilimu yokwelula umshini wokupakisha uhlelo lokulawula ugesi lwemoto ye-DC. Umshini wokupakisha ifilimu yokwelula unesiqalo esihle, ukusebenza kahle kokulawula ukubhuleka kanye nesivinini, ukulawula okulula, ngakho-ke, isidingo sokuqala esingenasinyathelo Izilungiselelo ezilungisekayo zisebenzisa kakhulu ukulawula isivinini semoto ye-DC. Uchungechunge lwemoto ye-Dc kanye ne-shunt, i-compound kanye nenxeba layo. Okulandelayo kuzokwethula umshini wokupakisha ifilimu yokwelula wesistimu yokulawula ugesi yemoto ye-DC.

a, umshini wokupakisha wefilimu yokwelula wohlelo lokulawula kagesi lwemoto ye-DC wesimiso kanye nembangela yokuqalisa kokumelana kwengalo yemoto ye-DC

Umshini wokupakisha wefilimu yokwelula wohlelo lokulawula ugesi lwemoto ye-DC. Umshini wokupakisha we-vacuum wefilimu yokwelula wemoto ye-DC uqalwa ngqo mkhulu kakhulu, uvame ukufinyelela izikhathi eziyi-10 ~ 20 zamanje ezilinganiselwe, ukhiqiza i-torque yokuqala enkulu kakhulu, ilungele ukuqala kwemoto, kodwa kulula kakhulu ukulimaza ukugoqa kwe-armature kwe-torque yemoto kanye ne-commutator, ngakho-ke, i-resistor yokuqala elandelanayo ene-armature inganciphisa ugesi wokuqala.

ngaphezu kwalokho, i-motor ye-dc evuselelwe ngokwehlukana ku-magnetic ebuthakathaka noma engekho, khiqiza & okunye; Isivinini & kulo lonke; I-Phenomenon, ngakho-ke i-armature ngaphambi kukagesi, eyokuqala kusekethe yokuvuselela exhunywe ku-voltage yokuvuselela, ukuvikelwa kokumelana kochungechunge ngesikhathi esifanayo. , ngakho-ke ukulawula ukuqala kwe-motor ye-dc kusekelwe ekumelaneni kochungechunge kanye nomklamo wokuvikela obuthakathaka we-magnetic.

2, inqubo yokulawula ukuqala kokuqala komshini wokupakisha we-dc motor armature ukumelana nenqubo eyodwa

umshini wokupakisha wefilimu yokwelula wohlelo lokulawula ugesi lwemoto ye-DC. Umshini wokupakisha wefilimu yokwelula imoto yamanje eqondile, indlela yokuqalisa yochungechunge lwebhokisi logesi, i-resistor, iyindlela yokuqalisa, kunesimiso sokuqala ngesivinini, isimiso sokuqala kwamanje nesikhathi esiqalile, okulandelayo kuzokwethula ngokulandelana.

1, isimiso sokuqala kwesivinini somshini wokupakisha ifilimu yokwelula

Umugqa wokuqala womshini wokupakisha wefilimu yokwelula ye-DC motor njengoba kuboniswe esithombeni, vala kuqala inkinobho yamandla i-Qs1, i-excitation loop current, lapho inkinobho yokucindezela i-SB2, ikhoyili yokuxhumana kagesi ye-KM1, i-KM ezikhiyayo, oxhumana nabo abavame ukuvula bevaliwe, oxhumana nabo abavame ukuvalwa benqanyulwa, i-armature current, ngenxa yokuthi ijubane lokuqala liphansi, i-speed relay yonke iphukile, ngakho-ke i-resistor yochungechunge i-R1, i-R2 kanye ne-R3: lapho ijubane likhuphuka liye enanini elithile, i-relay yejubane i-KS1 ngokuvamile ivulekile oxhumana nabo, i-resistor ochungechungeni olune-armature iyancipha, kuphela i-resistor ye-R2 kanye ne-R3 kuphela ene-armature, njengoba ijubane lemoto liqhubeka likhuphuka, i-speed relay i-KS2 ivame ukuvula oxhumana nabo kanye ne-Ks3 evame ukuvula oxhumana nabo ivaliwe, uchungechunge olune-armature resistance yizimoto eziqala ngokuphelele kusuka ku-short circuit.

Lapho isekethe yokuvuselela yokuphela kukagesi ivuselelwa, amandla e-electromotive abangelwa kukhoyili, i-R4 MD egobile, ukumelana kanye ne-diode yokukhululwa kwe-DVD, ukuvikelwa, i-VD futhi ibizwa ngokuthi i-diode yesondo eliyindilinga.

2, ukuqala komgomo wokupakisha ifilimu yokwelula ukugeleza komshini kanye nogesi

Ukupakisha ifilimu yokwelula isimiso sokugeleza komshini kanye nogesi wesekethe yokuqalisa ye-DC motor armature resistance one-way. Vala inkinobho yamandla kuqala, bese ucindezela inkinobho yokuqala SB2, i-coil ye-KT relay kanye ne-contactor kugesi ngesikhathi esifanayo, nge-coil ku-KMl KM1 ivame ukuvula oxhumana nabo bezikhiya, uchungechunge olunokumelana kwe-armature kokuqala kwemoto, ngesikhathi esifanayo i-coil ye-KA relay, oxhumana nabo be-KA bavame ukuvalwa banqanyulwa, okwenza i-coil ye-KM2 ingabi nogesi.

Uma ijubane likhuphuka liye esivinini esithile senjini, ugesi we-armature, amandla e-coil e-KA ayakhishwa, ukuvalwa kokuxhumana okuvamise ukuvalwa, ugesi we-coil ye-KM2, oxhumana nabo abavame ukuvula bavaliwe i-KM2, uchungechunge olune-armature ukumelana lwalufushane, ukuqala kwenjini, isikhathi sokudluliselwa sisetshenziswa lapho umzuzu, oxhumana nabo abavame ukuvula benqamula, qinisekisa ukuthi ikhoyili ye-KM2 ayisebenzi, futhi ibambezeleka ngemva kwesikhathi esithile, oxhumana nabo abavame ukuvula bavaliwe ukuze i-KT ilungiselele.

3, ukuqala komshini wokupakisha wefilimu yokwelula isikhathi sokuqala komshini wokupakisha

Umgomo wesikhathi somshini wokupakisha ifilimu yokwelula wesekethe yokuqalisa yokumelana ne-armature yemoto ye-dc. Vala i-power switch Qs1, bese ucindezela inkinobho yokuqala ethi SB2, ikhoyili yokuxhumana kagesi ye-KM1, ngokuvamile ivula oxhumana nabo be-KM1 self-locking, uchungechunge olune-motor armature resistance R1 kanye ne-R2, ugesi wekhoyili yokudlulisela i-KT1, ukubambezeleka ngemva kwesikhathi esithile, i-KT1 ivaliwe oxhumana nabo abavame ukuvula, ugesi wekhoyili yokudlulisela i-KA1, oxhumana nabo abavame ukuvula bavaliwe, i-resistor R1 ingaphansi, ugesi wekhoyili ye-KT2, ngesikhathi esifanayo ukubambezeleka ngemva kwesikhathi esithile, oxhumana nabo abavame ukuvula i-KT2 bavaliwe, ugesi wekhoyili ye-KA2, oxhumana nabo abavame ukuvula bavaliwe, i-resistor R2 nipple, i-motor igcwele.

Ukufuna isivumelwano esingcono kakhulu ngenkathi uthola ikhwalithi ngokuvamile kuyinhloso yokuqala yabakhiqizi abaningi bemishini yokulinganisa.

Singumhlinzeki onolwazi futhi sithole udumo oluhle phakathi kwamakhasimende omhlaba wonke. Njengoba sinezinhlobonhlobo zezipesheli, singenza ngokwezifiso ngokwezidingo zakho. Sithumelele umbuzo wakho ku-Smart Weighing And Packing Machine.

Ukuthuthukisa njalo isikali ngokuhambisana nempendulo yamakhasimende kuyindlela enhle yokubonisa ukuthi umkhiqizo wakho uyalalela futhi uyakhathalela.

isikali singasetshenziswa ngezindlela ezahlukene njengesikali sokuhlola.
