Explosion-proof sisitemu ya moteri ihindagurika ntabwo ihitamo mubihingwa nganda, ibirombe byamakara, cyangwa inganda zitunganya amavuta-ni itandukaniro riri hagati yimikorere ikomeza no guhagarika ibiza. Twabonye ibikoresho bitakaza inshuro eshatu z'umusaruro kuko moteri yabafana yikandagiye mugihe cyo kumenya gaze ihindagurika. Abandi basimbuye VFDs inshuro ebyiri mu mezi 18 - gusa basanze intandaro atari uguhuza software cyangwa gukingira insinga, ahubwo ni ukudahuza kwibanze hagati yicyiciro cyo gukumira moteri, igipimo cyiziritse, hamwe ninshingano zukuri kwisi. Muri Zibo Hongcheng Fan Co., Ltd., dushushanya moteri itwara ibintu biturika bitagaragara nkibice bigize standalone, ahubwo nkibice bigize igenzura ryoguhumeka ikirere - byakozwe kuva kumuyaga kugeza kumazu kugirango byubahirizwe icyarimwe GB 3836.1–2021 (Ubushinwa bwa Ex Standard), IEC 60079-0, nibisabwa guhuza inganda za VFD nka IEEE 519-2022.
Kuki Moteri Zisanzwe za VFD zananiranye muri Zone Ziteje akaga - Ndetse hamwe na label ya “Ex”
Abakoresha benshi bibwira ko ikirango "giturika-giturika" cyemeza imikorere ya VFD itekanye. Ntabwo aribyo. Moteri yemejwe kubintu bihamye Ex d IIB T4 irashobora gushyuha munsi ya 30 Hz PWM yumubyigano wa voltage, bitesha agaciro ibyiciro bya H byihuse kuruta uko byerekana ubushyuhe bwumuriro. Twapimye ubushyuhe bwa rotor hejuru ya 42 ° C hejuru yicyapa kuri 25 Hz mubidukikije byafunzwe-bihagije kugirango karubone irangi kandi ikurura amakosa yubutaka. Ikirushijeho kuba kibi: imiterere ya sinusoidal itariyongera byongera igihombo cya eddy mukigo cyaka umuriro, kizamura ubushyuhe bwubuso burenze T-amanota. Niyo mpanvu moteri yacu iturika-idashobora guhindagurika ikurikirana itangirana na statut ebyiri zemewe-zoherejwe na H H * hiyongereyeho * ibyuma byongerewe imbaraga byihanganira dv / dt-hamwe n'inzu zakozwe kugeza kuri mm 0,05 mm kugirango twirinde gutwarwa ningaruka ziterwa na voltage isanzwe.
Kwishyira hamwe-Kwisi: Ibyo Ingeneri yawe Igenzura ikeneye kumenya
Guhuza VFD ntabwo bijyanye n'umurongo wa torque-ni ukubaho kwa electronique. Moteri yacu ya FBD (DⅠ) iturika-idashobora guhinduka moteri ya moteri irimo ibyuma byubatswe muri RFI byapimwe kuri 4 kV ubudahangarwa bw'umubiri hamwe no gukingira insinga zimbere ziva kure y'amashanyarazi. Ariko kwishyira hamwe birananirana cyane kuri interineti: topologiya idahwitse, insinga zidafite kodegisi zidafite aho zihurira na moteri, cyangwa inshuro zitwara VFD zashyizwe hejuru ya 8 kHz ahantu hafunzwe aho imiraba igaragara yongerera imbaraga za voltage. Dutanga ibikoresho byuzuye bya komisiyo-harimo na ferrite cores, imitsi yo hasi, hamwe na 1: 1 yihinduranya yo gutandukanya ibitekerezo - ntabwo ari inyongera, ahubwo nkibice byateganijwe bya sisitemu. Iyo uruganda rutunganya ibicuruzwa muri Shandong rwagabanije amasaha atateganijwe ku gipimo cya 73%, impinduka ntabwo yari moteri ubwayo. Byakurikizaga ingingo imwe hanyuma tugashyiraho uburyo bwabanje kugeragezwa 12-pulse ikosora kugirango tugabanye THD munsi ya 5% kuri moteri.
Customisation itabangamiye icyemezo
“Urashobora gukora ibisasu biturika * na * birwanya ruswa * kandi bigakorerwa kuri 110 ° C.” Yego - ariko gusa niba ibikoresho, gukonjesha, hamwe no kwemeza inzira. Inzu ya Titanium irwanya ruswa ya H₂S ariko ikora ubushyuhe nabi; ibi tubikemura hamwe na axial fin ya array hamwe nuyoboro uhumeka-mwuka ukomeza ubushyuhe bwa T3 ndetse no kuri 100% umutwaro muri 55 ° C. Kubakunzi ba desulfurizasi ikoresha gazi ya flue itose, twashyizemo epoxy-yometseho umuringa wumuringa * kandi * tugaragaza ibyuma bifata ibyuma bidafite ibyuma byerekana pasiporo - ntabwo ari amanota gusa. Buri gice cyabigenewe gikorerwa ibizamini byuzuye byuzuye kuri 105% byapimwe mumasaha 72 imbere yicyumba cyacu cya kabiri cya Zone 1, hamwe nubushakashatsi bwa termografiya buri minota 15. Nta bigufi. Nta bikoresho "bihwanye". Nta kongera kwemeza gutinda.
Guhitamo Uburyo Bwiza Kubaza Ibibazo Byambere
- Ni ubuhe buryo busanzwe bwo gukora buke? Kwiruka munsi ya 20 Hz bisaba gukonjesha bidasanzwe-moderi yacu yihuta ikoresha ibyuma bisohora hanze bifite imbaraga zigenga, ntabwo ari abafana baterwa na shaft bahagarara kuri RPM nkeya.
- Nibihe bihuza byiganje kuri gride yawe? Niba urubuga rwawe rufite imitwaro iremereye ya arc, moteri zacu zirimo guhuza imiterere ya stator laminations kugirango uhagarike rezo ya 5 na 7.
- Ni kangahe igomba gutangira nyuma yo gukuraho amakosa? Guhumeka amakara bisaba ≤3-isegonda isubirana-duhuza amabanki ya capacitori agumana umunezero mwinshi mugihe cya micro-interruption.
- Kubungabunga bibera he? Agasanduku kacu ka modular gasanduku yemerera igeragezwa ryuzuye ridashobora gukingurwa udafunguye flameproof - birakomeye mugihe akazi gashyushye gatanga igihe cyo kwinjira.
Ntabwo tugurisha moteri. Dutanga ibyiringiro byindege byemewe. Buri moteri idashobora guhindagurika moteri isiga ikigo cyacu cya Zibo hamwe na raporo yikizamini cyerekana ko nta mutwaro uremereye (<2%), amplitude amplitude (<1.8 mm / s RMS), hamwe nubushyuhe bwubushyuhe bwo hejuru hejuru yikibazo cya VFD. Nuburyo kwizerwa bigira injeniyeri-ntabwo byasezeranijwe. Sura https://www.hongchengfan.com kubijyanye na tekiniki ya tekiniki, inyandiko zisaba kuri VFD-moteri ihuye, no kubona mu buryo butaziguye injeniyeri za porogaramu zerekanye ahantu hasaga 2100 hashyizweho akaga kuva 2020.
