Explosion-proof Iinkqubo zeemoto eziguquguqukayo azikhethi kwizityalo zekhemikhali, imigodi yamalahle, okanye iindawo zokucokisa ioyile-zingumahluko phakathi kokusebenza okuqhubekayo kunye nokuvalwa kwentlekele. Siye sabona izibonelelo ziphulukana neenguqu ezintathu zemveliso ngenxa yokuba i-motor fan yakhubeka ngexesha lokubonwa kwegesi eguqukayo. Abanye bathathe indawo yee-VFDs eziqhelekileyo kabini kwiinyanga ezili-18-kuphela ukufumanisa unobangela yayingekokulungiswa kwesoftware okanye ukukhuselwa kwentambo, kodwa ukungahambelani okubalulekileyo phakathi kweklasi yokugquma iimoto, ukukala kwendawo ebiyelweyo, kunye nomjikelo wokwenyani wehlabathi. Kwi-Zibo Hongcheng Fan Co., Ltd., siqulunqa ii-motor frequency frequency-proof-proof-proof motors kungekhona njengezixhobo ezizimeleyo, kodwa njengeendawo ezidibeneyo zokulawula ukuhamba komoya-eyenziwe ukusuka ekujikelezeni ukuya kwizindlu ukuze zithotyelwe ngaxeshanye ne-GB 3836.1-2021 (i-Ex standard ye-China), i-IEC 60079-0, kunye neemfuno ze-industrial 51D IEEcompatibility 51D IEEcom kunye ne-IEEcom 51D 2021 IEEcom. imida.
Kutheni iiMoto eziMgangatho zeVFD zisilela kwiiNdawo ezinobungozi-NangeeLebhile "Ex".
Abasebenzisi abaninzi bacinga ukuba ileyibhile “yobungqina bokudubula” iqinisekisa ukusebenza ngokukhuselekileyo kweVFD. Akunjalo. Imoto eqinisekisiweyo yeemeko ezimileyo ze-Ex d IIB T4 inokutshisa ngaphantsi kwe-30 Hz PWM yoxinzelelo lwamandla ombane, ithobe ukugquma kweKlasi H ngokukhawuleza kunokuba imodeli ye-thermal iqikelele. Silinganise ubushushu bomphezulu we-rotor 42 ° C ngaphezu kwe-nameplate kwi-25 Hz kwiindawo ezivaliweyo zetonela-ngokwaneleyo ukwenza i-carbonize ivanishi kunye nokuqalisa iimpazamo zomhlaba. Okubi kakhulu: iifom ze-non-sinusoidal waveforms zonyusa ilahleko yangoku ye-eddy kwiindawo ezivaliweyo ezingatshiyo, ziphakamisa ubushushu bomhlaba ngaphaya kwemida ye-T-rating. Yiyo loo nto uthotho lwethu lweemoto eziguquguqukayo ezinobungqina boqhushumbo luqala ngamajiko-jiko estator aqinisekisiweyo aphindwe kabini-Isigqubuthelo sodidi H *plus* ii-slot liners zomeleziweyo ezikwaziyo ukumelana ne-dv/dt transients ephezulu-kunye nezindlu ezenziwe ngoomatshini ukuya ku-± 0.05 mm ukugxila ukunqanda imisinga ethweleyo ebangelwa yivoltheji yemowudi eqhelekileyo.
Ukudityaniswa kwehlabathi lokwenyani: Yintoni ekufuneka uyazi iNjineli yakho yoLawulo
Ukuhambelana kwe-VFD akukho malunga ne-torque curves-imalunga nokusinda kwe-electromagnetic. Uthotho lwethu lwe-FBD(DⅠ) lwe-FBD(DⅠ) olunobungqina bokuqhuma kweemotor eziguquguqukayo ziquka izihluzi ze-RFI ezakhelwe ngaphakathi ezithelekelelwa kwi-4 kV yokugonywa kotyando kunye neengcingo zangaphakathi ezikhuselweyo zihanjiswe kude nezikhokelo zamandla. Kodwa udibaniso lusilela kakhulu kujongano: i-topology engachanekanga, iintambo zekhowudi ezingakhuselekanga ezisebenza ngokunxuseneyo neemoto ezikhokelayo, okanye i-VFD carrier frequencies iseti ngaphezulu kwe-8 kHz kwiindawo ezivaliweyo apho amaza abonakalisiweyo akhulisa i-voltage spikes. Sinikezela ngeekhithi zokugunyazisa ezipheleleyo-kubandakanya ii-ferrite cores, i-grounding lugs, kunye ne-1: 1 i-isolation transformers yeesekethe zempendulo-kungekhona njengezongezo, kodwa njengeendawo ezinyanzelekileyo zenkcazo yenkqubo. Xa indawo yokucoca eShandong inciphisa ixesha lokuphumla elingacwangciswanga ngama-73%, utshintsho yayingeyiyo injini ngokwayo. Yayinyanzelisa ukusekwa kwendawo enye kunye nokufakela ukhetho lwethu oluvavanyiweyo lwangaphambili lwe-12-pulse rectifier ukusika iTHD ngaphantsi kwe-5% kwizikhululo zeemoto.
Ukwenza ngokwezifiso okungasichaphazeliyo isiqinisekiso
"Ngaba ungayenza ikhuseleke ukudubula *kwaye* ikwazi ukumelana nomhlwa *kwaye* ibaleke kwi-110°C kwindawo engqongileyo?" Ewe-kodwa kuphela ukuba izinto eziphathekayo, ukupholisa, kunye neendlela zokuqinisekisa zihambelana. Izindlu ze-Titanium zixhathisa ukubola kwe-H₂S kodwa ziqhuba ubushushu kakubi; sisombulula oku nge-axial fin arrays edibeneyo kunye nokunyanzeliswa kwe-air ducting egcina ubushushu bomphezulu we-T3 nakwi-100% yomthwalo kwi-55 ° C ambient. Kubalandeli be-desulfurization abaphatha irhasi emanzi yeflue, sishumeka i-epoxy-coated copper windings *kwaye* sicacise iziqhoboshi zentsimbi engenastainless ezinezatifikethi zokupasa-hayi nje ukuphawula kwebakala. Yonke iyunithi yesiko ifumana uvavanyo olugcweleyo lokutshisa ngaphakathi kwi-105% yombane olinganiswe ngeeyure ezingama-72 ngaphakathi kwigumbi lethu lovavanyo lweKlasi yesi-II yeNdawo yoku-1, ngokujongwa kwe-thermographic rhoqo ngemizuzu eli-15. Akukho ndlela zimfutshane. Akukho zixhobo "ezilinganayo". Akukho kulibaziseka kwesiqinisekiso kwakhona.
Ukukhetha Okulungileyo Kuthetha Ukubuza Imibuzo Elungileyo Kuqala
- Yeyiphi eyona frequency yakho encinci yokusebenza? Ukubaleka ngaphantsi kwe-20 Hz kufuna ukupholisa okukhethekileyo-iimodeli zethu ezinesantya esiphantsi zisebenzisa izivuthelo zangaphandle ezinamandla azimeleyo, hayi iifeni ezifakwe kwi-shaft ezihlala kwi-RPM ephantsi.
- Zeziphi iiharmoni ezilawula igridi yakho? Ukuba indawo yakho inemithwalo enzima yesithando somlilo, iimotor zethu ziquka i-harmonic-tuned stator laminations ukucinezela i-resonance ye-5 kunye ne-7.
- Kufuneka iqale ngokukhawuleza kangakanani emva kokususwa kwempazamo? I-ventilation yamalahle idinga i-≤3-yesibini ukubuyiswa-sidibanisa iibhanki ze-capacitor ezigcina i-excitation yentsimi ngexesha lokuphazamiseka kwe-micro.
- Kwenzeka phi ulondolozo? Iibhokisi zethu zeemodyuli ze-terminal zivumela uvavanyo olupheleleyo lokumelana nokukhusela ngaphandle kokuvula i-joint yokutshisa-ibaluleke kakhulu xa umsebenzi oshushu uvumela ukukhawulela ixesha lokufikelela.
Asithengisi iinjini. Sinikezela ngesiqinisekiso sokuhamba komoya esiqinisekisiweyo. Zonke iimoto eziguquguqukayo ezinobungqina bokudubula zishiya indawo yethu yeZibo kunye nengxelo yovavanyo elandelekayo ebonisa ukungalingani kwangoku akukho mthwalo (<2%), i-vibration amplitude (<1.8 mm/s RMS), kunye nokunyuka kobushushu bomphezulu phantsi koxinzelelo lwe-VFD eyenziwe ngamaza. Yiloo ndlela ukuthembeka kwakhiwa ngayo-akuthenjiswanga. Ndwendwela https: //wwwwchengfan.com kwiinkcukacha zedatha yezobugcisa, amanqaku esicelo kuthelekiso lwe-VFD-motor, kunye nokufikelela ngokuthe ngqo kwiinjineli zezicelo ezichaze ngaphezulu kwe-2,100 yofakelo lwendawo enobungozi ukusukela ngo-2020.
