Isithando somlilo esimaphakathi siyidivayisi enikezela ngogesi eguqula amandla angu-50Hz AC abe amandla amaphakathi (300Hz kuya ku-100Hz), bese iguqula amandla ezigaba ezintathu e-AC ibe amandla e-DC, bese iguqula amandla e-DC abe amandla ashintshwayo aphakathi nendawo, ashintsha amandla e-AC abe yi-DC. igeleza ngama-capacitor namakhoyili wokungenisa.Khiqiza imigqa yamandla kazibuthe anobukhulu obukhulu, unqamule into yensimbi kukhoyili yokungeniswa, sebenzisa umgomo wokungeniswa kukagesi ukuze ukhiqize amandla amakhulu ensimbi yensimbi, ushise izinto zensimbi, futhi uyincibilikise.
Isithando somlilo sokungenisa imvamisa emaphakathi siwumthwalo wesistimu ohlukile.Ngesikhathi senqubo yokusebenza, ama-harmonic currents angeniswa kugridi yamandla, okubangela i-pulse current voltage on the impedance isici segridi yamandla, okubangela ukushintshashintsha kwamandla kagesi kugridi yamandla, futhi kuthinte ikhwalithi yohlelo lokuphakelwa kwamandla kanye nokuphepha kokusebenza kwemishini. .Njengoba ukunikezwa kwamandla okuhweba kwesithando somlilo esiphakathi kuba imvamisa emaphakathi ngokusebenzisa isiguquli semvamisa yokulungiswa, igridi yamandla izokhiqiza inani elikhulu lama-harmonics ayingozi ngesikhathi sokusebenza, okungenye yemithombo emikhulu ye-harmonic ye-oda eliphezulu kakhulu umthwalo wegridi yamandla.
Izici ezinhlanu zesithando somlilo esiphakathi nendawo
1. Yonga imali
Ukushisisa okusheshayo, ukukhiqiza okuphezulu, i-air oxidation carburization encane, ukonga izinto ezingavuthiwe nezindleko, nokwelula impilo yesevisi yamathuluzi abrasive.
Ngenxa yokuthi umgomo wesithando somlilo esiphakathi nendawo siwumagnetic, ukushisa okukhiqizwa isithando somlilo esiphakathi nendawo kukhiqizwa insimbi ngokwayo.Abasebenzi abajwayelekile bangakwazi ukwenza umsebenzi oqhubekayo wokwenza umsebenzi wokwakha kungakapheli imizuzu eyishumi ngemuva kokusebenzisa isithando somlilo esiphakathi nendawo, ngaphandle kwesidingo sokukhiqiza isithando somlilo.Izisebenzi zaqala umsebenzi wokudubula nokuvala iziko kusenesikhathi.Ngenxa yokuthi le ndlela yokushisisa ishisa ngokushesha futhi ine-oxidation encane, ukukhishwa kwe-oxidation kwe-intermediate frequency heat steel castings kungu-0.5% kuphela, ukukhishwa kwe-oxidation kokushisisa kwesithando segesi kungu-2%, kanti isithando somlilo samalahle esiluhlaza sidlula u-3%.Inqubo yokushisisa imvamisa emaphakathi isindisa izinto ezisetshenziswayo, uma kuqhathaniswa neziko lamalahle aluhlaza, ithani elilodwa lensimbi yonga amapuleti ensimbi engenasici angu-20-50KG.Izinga layo lokusebenzisa impahla eluhlaza lingafinyelela ku-95%.Ngenxa yokuthi ukushisisa kufana futhi umehluko wezinga lokushisa phakathi kwendawo ewumgogodla mncane, impilo yesevisi ye-forging die yanda kakhulu ngesikhathi sokufoja.I-forging roughness ingaphansi kuka-50um, futhi ubuchwepheshe bokucubungula buyawonga amandla.Ukushisa okuphakathi nendawo kungonga amandla ngo-31.5% -54.3% uma kuqhathaniswa nokushisisa uwoyela, kanye negesi yokushisisa Okonga Amandla ngo-5% -40%.Izinga lokushisa lihle, izinga le-scrap lingancishiswa ngo-1.5%, izinga lokukhipha lingakhushulwa ngo-10% -30%, futhi impilo yesevisi yethuluzi le-abrasive inganwetshwa ngo-10% -15%.
2. Amaphuzu okuvikela imvelo
Indawo enhle yamahhovisi, ithuthukisa indawo yehhovisi labasebenzi kanye nesithombe somkhiqizo wenkampani, ukungcoliswa kweqanda, ukonga amandla.
Uma kuqhathaniswa nezitofu zamalahle, izitofu zokushisa zokungeniswa ngeke zisabhenywa izitofu zamalahle ngaphansi kokushisa okukhulu, ezingahlangabezana nemithetho ye-Environmental Protection Agency.Ngaphezu kwalokho, ingalolonga isithombe somkhiqizo wangaphandle wenkampani futhi yakhe inkambiso yokuthuthukisa imboni yemboni yokukhiqiza.Ukushisa kwe-induction ukushisisa kwamandla kagesi esithandweni somlilo kusuka ekamelweni lokushisa kuya ku-100 ° C, ukusetshenziswa kwamandla kungaphansi kuka-30 ° C, futhi ukusetshenziswa kwe-forging kungaphansi kuka-30 ° C.Indlela yokuhlukanisa yokusetshenziswa kwe-forging
3. Ukushisa izithelo
Ukushisa okufanayo, umehluko omncane wokushisa phakathi kwengqikithi nendawo, ukunemba kokulawula izinga lokushisa eliphezulu
Ukushisa kwe-induction kudala ukushisa ensimbi ngokwayo, ngakho-ke ukushisisa kuyalingana futhi umehluko wezinga lokushisa phakathi komnyombo nongaphezulu mncane.Ukusetshenziswa kwesistimu yokulawula izinga lokushisa kungalawula kahle izinga lokushisa, kuthuthukise ikhwalithi yomkhiqizo kanye nezinga lokuphasa.
4. Linganisa
Isithando somlilo esiphakathi nendawo sishisa ngokushesha, insimbi yesithando somlilo isebenzisa amandla kazibuthe kagesi angadluli ama-degree angu-500, futhi ukuncibilika kuphelele futhi kuyashesha.
5. Ukusebenza kokuphepha
Isistimu yokuqapha ekude yesithando somlilo sikagesi esiphakathi nendawo ikhethiwe, efanelekile endaweni yokukhiqiza yezimboni.Ikhono eliqinile lokulwa nokuphazamiseka kanye nesici sokuphepha esiphezulu.Ayikho intambo exhunywe phakathi kwedivayisi yokusebenza nedivayisi elawulwayo, okungukuthi, isilawuli kude.Kuyo yonke imisebenzi eyinkimbinkimbi, cindezela izinkinobho zesilawuli kude ukude.Ngemuva kokuthola imiyalelo, isithando somlilo sikagesi esiphakathi nendawo singaqedela imisebenzi ehambisanayo isinyathelo ngesinyathelo ngokuya ngenqubo enhle.Ngenxa yokuthi isithando somlilo sikagesi siwumshini kagesi we-voltage ephezulu, akuphephile nje kuphela, kodwa futhi kungagwema ukulimala kwesithando somlilo ngenxa yokwethuka okubangelwa amaphutha okusebenza.
Kungani isithando somlilo esiphakathi sikhiqiza ama-harmonics
I-Harmonics izofaka engozini kakhulu ukusebenza okuphephile kwegridi yamandla.Isibonelo, i-harmonic current izobangela ukulahlekelwa kwensimbi eyengeziwe ye-vortex ephezulu-frequency ku-transformer, okuzokwenza ukuthi i-transformer ishise ngokweqile, inciphise umthamo ophumayo we-transformer, ikhulise umsindo we-transformer, futhi ibeke engozini impilo yesevisi ye-transformer. .Umphumela wokunamathela we-harmonic currents unciphisa isigaba esiphambanayo njalo somqhubi futhi ukhulise ukulahlekelwa komugqa.I-Harmonic voltage ithinta ukusebenza okuvamile kwezinye izinto zikagesi kugridi, ibangele amaphutha okusebenza emishinini yokulawula okuzenzakalelayo kanye nokuqinisekiswa kokulinganisa okunganembile.I-Harmonic voltage kanye namanje kuthinta ukusebenza okuvamile kwemishini yokuxhumana ye-peripheral;i-overvoltage yesikhashana kanye nokweqisa kwesikhashana okubangelwa ama-harmonics kulimaza ungqimba lokufakwa kwemishini nemishini, okuholela emaphutheni esigaba esifushane sesekhethi yezigaba ezintathu kanye nokulimala kwama-transformer;i-harmonic voltage kanye nenani lamanje lizodala i-resonance yochungechunge oluyingxenye kanye nokuzwakala okuhambisanayo kugridi yamandla omphakathi, okuholela ezingozini ezinkulu.Kuyo yonke inqubo yokunikezwa kwamandla kagesi oguquguqukayo, ugesi wokuqala ozinzile we-DC uwukunikezwa kwamandla okushintsha igagasi lesikwele, okulingana nokunqwabelana kwamagagasi e-sine anamagagasi amaningi e-high-order pulse currents.Nakuba isifunda se-post-stage sidinga isihlungi, i-harmonics ayikwazi ukuhlungwa ngokuphelele, okuyimbangela ye-harmonics.
Amandla e-Harmonic wesithando somlilo esiphakathi
Amandla okukhiphayo wesithando somlilo esiphakathi nendawo ahlukile, futhi ama-harmonics ahlobene nawo ahlukile:
1. Amandla emvelo wesithando somlilo esiphakathi kwamandla aphezulu aphakathi kuka-0.8 no-0.85, isidingo samandla asebenzayo sikhulu, futhi okuqukethwe kwe-harmonic kuphezulu.
2. Amandla emvelo esithandweni somlilo esiphakathi samandla aphansi aphakathi kuka-0.88 no-0.92, futhi isidingo samandla asebenzayo sincane, kodwa okuqukethwe kwe-harmonic kuphezulu kakhulu.
3. I-harmonics eseceleni enetha yesithando somlilo esiphakathi nendawo ikakhulukazi i-5th, 7th kanye ne-11.
Indlela yokulawula i-Harmonic yesithando somlilo esiphakathi
Izihlungi ezicushwe kanye izikhathi ezi-5, 7, 11 kanye ne-13 zenzelwe.Ngaphambi kwesinxephezelo sesihlungi, isici samandla sesixhumanisi sokuncibilikisa isithando somlilo esimaphakathi sekhasimende singu-0.91.Ngemuva kokuthi okokusebenza kwesinxephezelo sesihlungi sekuqalile ukusebenza, isinxephezelo esiphezulu singu-0.98 capacitive.Ngemuva kokuthi okokusebenza kwesinxephezelo kwesihlungi sekuqalile ukusebenza, inani eliphelele lokuhlanekezelwa kwamandla kagesi (inani eliphelele lokuhlanekezelwa kwe-harmonic) lingu-2.02%.Ngokwezinga lamandla elijwayelekile le-GB/GB/T 14549-1993, inani le-voltage esebenzayo ye-harmonic (10KV) lingaphansi kuka-4.0%.Ngemva kokwenza izihlungi kuma-harmonic currents wesi-5, 7th, 11th kanye ne-13th, izinga lokuhlunga cishe lingama-82∽84%, elidlula inani lokulawula lezinga lemboni yenkampani yethu.Umphumela wokuhlunga isinxephezelo muhle.
