Yelula ifilimu
umshini wokupakisha yohlelo lokulawula ugesi lwe-dc motor.
Umshini wokupakisha wefilimu yokwelula i-dc motor inesiqalo esihle, ukubhuleka kanye nokusebenza kokulawula isivinini, ukulawula okulula, ngakho-ke, isidingo sangaphambi kwesikhathi esilungisekayo esingenasinyathelo Izilungiselelo zisebenzisa kakhulu isilawuli sejubane se-dc motor.
Dc motor series kanye shunt, kwakwakhe nesilonda sakhe.
Okulandelayo kuzokwethula umshini wokupakisha wefilimu owelula wesistimu yokulawula kagesi ye-dc motor.
a, umshini wokupakisha wefilimu owelula wesistimu yokulawula kagesi ye-dc motor yesimiso kanye nembangela yokuqala kokumelana ne-dc motor armature
welula umshini wokupakisha wefilimu wohlelo lokulawula ugesi lwe-dc motor.
I-Stretch film vacuum
packaging machine yamanje ye-dc motor iqalwa ngokuqondile inkulu kakhulu, imvamisa ifinyelela izikhathi eziyi-10 ~ 20 kuneyamanje elinganisiwe, ikhiqiza i-torque yokuqala enkulu, ilungele ukuqala kwemoto, kodwa kulula kakhulu ukulimaza ukujika kwe-armature I-torque ye-motor kanye ne-commutator, ngakho-ke, isinqamuleli sokuqalisa ochungechungeni nge-armature singanciphisa imanje lokuqala.
ngaphezu kwalokho, i-dc motor ejabulile ngokwehlukana ibuthaka noma ziro kazibuthe, khiqiza & nokunye;
Isivinini & kuyo yonke;
I-Phenomenon, ngakho-ke i-armature ngaphambi kukagesi, eyokuqala kumjikelezo we-excitation exhunywe ku-voltage evusa amadlingozi, ukuvikelwa kochungechunge lokumelana ngesikhathi esifanayo.
, ngakho-ke isilawuli sokuqala semoto ye-dc sisekelwe ekuphikisweni kochungechunge kanye nomklamo wokuvikela kazibuthe obuthakathaka.
2, ukwelula umshini wokupakisha wefilimu i-dc motor armature ukumelana nenqubo yokulawula ukuqalisa
welula umshini wokupakisha wefilimu wohlelo lokulawula ugesi lwe-dc motor.
Umshini wokupakisha we-Stretch film oqondile wamanje we-motor electric box series resistor startup method ungaphezulu, kunomgomo wokuqalwa kwesivinini, umgomo wokuqala wamanje nesikhathi esiqalisiwe, okulandelayo kuzokwethula ngokulandelana.
I-1, umgomo wokuqalisa isivinini somshini wokupakisha ifilimu
I-dc motor armature resistance yomugqa wokuqala womshini wokupakisha ifilimu owelula njengoba kukhonjisiwe esithombeni, qala ngokuvala i-switch switch Qs1, i-excitation loop current, lapho inkinobho yokusunduza i-SB2, ikhoyili kagesi yokuxhumana ye-KM1, i-KM yokuzikhiya, oxhumana nabo abavamise ukuvuleka. kuvaliwe, othintana nabo ngokuvamile abavaliwe ukunqamula, armature zamanje, ngenxa motor ekuqaleni ijubane isiqalo iphansi, isivinini edluliselwe zonke ephukile, ngakho uchungechunge resistor R1, R2 kanye R3: lapho isivinini sikhuphukela inani elithile, isivinini I-relay KS1 ngokuvamile othintana nabo abavulekile bayavalwa, i-resistor ochungechungeni ene-armature iyancishiswa, ukumelana kuphela kwe-R2 ne-R3 uchungechunge nge-armature, njengoba ijubane lemoto liqhubeka nokukhuphuka, i-speed relay KS2 ngokuvamile ivula othintana nabo futhi i-Ks3 ngokuvamile ivulekile oxhumana nabo. ivaliwe, uchungechunge nge-armature ukumelana kukhona motor iqale ngokuphelele kusukela wesifunda iDemo.
lapho isifunda esivusa amadlingozi sokunqamuka kukagesi, amandla e-electromotive angeniswa kukhoyili, i-R4 MD ejikajikayo, ukumelana ne-diode yokukhishwa kwe-DVD, ukuvikela, i-VD futhi ebizwa ngokuthi i-fly-wheel diode.
2, ukwelula ifilimu emaphaketheni isimiso sokugeleza kukagesi ukuqala
ukwelula ukupakishwa kwefilimu umgomo wokugeleza kukagesi we-dc motor armature resistance yesekethe yokuqala yokuqala.
Vala isishintshi samandla kuqala, bese ucindezela inkinobho yokuqala SB2, ikhoyili ye-KT edluliselwe isikhathi kanye nokuxhumana nogesi ngesikhathi esifanayo, ikhoyili eku-KMl KM1 ngokuvamile ivula othintana nabo be-self-locking, uchungechunge olunokumelana ne-armature ye-motor. qala, ngesikhathi esifanayo dlulisa ugesi wekhoyili we-KA, oxhumana nabo be-KA ngokuvamile abavaliwe banqamule, okwenza ikhoyili ye-KM2 ingabi nawo ugesi.
lapho ijubane likhuphukela kwijubane elithile lemoto, i-armature current, amandla ekhoyili e-KA akhululwa, ukuvalwa kokuxhumana okuvamise ukuvaleka, ugesi wekhoyili we-KM2, oxhumana nabo ngokuvamile abavulekile bavaliwe i-KM2, uchungechunge olunokumelana nezikhali lwalumfushane, ukuqala kwemoto, ukudluliselwa kwesikhathi kusetshenziswa lapho umzuzu, i-KT ngokuvamile evula abathintwayo inqamuka, qiniseka ukuthi ikhoyili ye-KM2 ngeke ibe nogesi, futhi ibambezeleka ngemva kwesikhathi esithile, ngokuvamile ivula othintana nabo abavaliwe ukuze ikhoyili ye-KT, KM2 ilungiswe.
3, ukwelula umshini wokupakisha ifilimu isimiso isikhathi isiqalo
umgomo wesikhathi womshini wokupakisha wefilimu we-dc motor armature resistance yesekethe yokuqala yokuqala.
Ivale iswishi yamandla i-Qs1, bese ucindezela inkinobho yokuqala SB2, ikhoyili yokuxhumana kagesi ye-KM1, ngokuvamile evula othintana nabo be-KM1 yokuzikhiya, uchungechunge olunokumelana ne-motor armature resistance R1 no-R2, ugesi wekhoyili odluliselwe isikhathi we-KT1, ukubambezeleka ngemva kwesikhathi esithile isikhathi, i-KT1 ivamise ukuvuleka othintana nabo, idlulisele ugesi wekhoyili we-KA1, othintana nabo abavame ukuvuleka bavaliwe, i-resistor R1 ingaphansi, ugesi wekhoyili we-KT2, ngesikhathi esifanayo ukubambezeleka ngemva kwesikhathi esithile, i-KT2 ivamise ukuvula oxhumana nabo bevaliwe, ugesi wekhoyili we-KA2, othintana nabo ngokuvamile abavulekile bavaliwe, ukumelana nengono ye-R2, injini inyakaza ngokugcwele.
ukufuna idili elingcono kakhulu kuyilapho ukuthola ikhwalithi ngokuvamile kuwumgomo wokuqala womkhiqizi womshini wesisindo esiningi.
Singabahlinzeki abanolwazi futhi sesizuze idumela elihle phakathi kwamakhasimende omhlaba. With anhlobonhlobo in okunikezwayo, singakwazi ngokwezifiso ngokuvumelana nemfuneko yakho. Sithumelele uphenyo lwakho kwaSmart Weighing And
Packing Machine.
Ukuthuthukisa njalo isikali ngokuhambisana nempendulo yekhasimende kuyindlela enhle yokubonisa ukuthi umkhiqizo wakho uyalalela futhi uyakhathalela.
I-weigher ingasetshenziswa ngezindlela ezahlukene njenge-checkweigher.
