Explosion-proof akasiyana frequency mota masisitimu haasarudze mumakemikari zvidyarwa, migodhi yemarasha, kana mafuta ekunatsa-ndiwo mutsauko uripo pakati pekuenderera kwekushanda uye kuvharika kwenjodzi. Isu takaona zvivakwa zvichirasikirwa neatatu ekuchinja kwekugadzira nekuti fan fan yakagumburwa panguva yekusagadzikana gasi kuona. Vamwe vakatsiva akajairwa maVFDs kaviri mumwedzi gumi nemasere-kungoona chikonzero chaive chisiri chekugadzira software kana tambo yekudzivirira, asi kusawirirana kwakakosha pakati pekirasi yekuvharisa mota, chiyero chekuvharirwa, uye chaiyo-yepasirese basa kutenderera. KuZibo Hongcheng Fan Co., Ltd., tinogadzira kuputika-humbowo kusiyanisa ma frequency mota kwete seakamira ega ega, asi seakabatanidzwa airflow control node-akagadzirwa kubva kumhepo kuenda kudzimba kuti atevedzere panguva imwe chete neGB 3836.1-2021 (China's Ex standard), IEC 60079-0, uye maindasitiri ekukuvadza 51D 29 DFE com. limits.
Nei Standard VFD Motors Ichikundikana munzvimbo dzine Njodzi—Kunyangwe ne “Ex” Labels
Vazhinji vashandisi vanofungidzira "kuputika-chiratidzo" label inovimbisa yakachengeteka VFD kushanda. Hazvidaro. Mota yakasimbiswa ye static Ex d IIB T4 mamiriro inogona kupisa pasi pe30 Hz PWM voltage stress, inoshatisa Class H insulation nekukurumidza kupfuura kufembera kwekupisa kwemoto. Takayera tembiricha yerotor 42°C pamusoro pezita rezita pa25 Hz munzvimbo dzakavharwa dzemugero-zvakakwana kuti carbonize varnish uye kukonzeresa kukanganisa kwepasi. Zvakaipisisa: asiri-sinusoidal waveforms anowedzera kurasikirwa kwazvino eddy mumivharo yemoto, kusimudza tembiricha yepamusoro kupfuura T-rating margins. Ndosaka yedu inoputika-inoratidza kusiyanisa frequency mota inoteedzana ichitanga neiviri-yakasimbiswa stator windings-Kirasi H insulation *pamwe* yakasimbisa slot liners inopokana nepamusoro dv/dt inotenderera-uye dzimba dzakagadzirwa kusvika ± 0.05 mm concentricity kudzivirira kubereka mafungu anokonzereswa neyakajairwa-modhi voltage.
Real-World Kubatanidzwa: Izvo Zvako Kudzora Injiniya Inoda Kuziva
Kuenderana kweVFD hakusi nezve torque curves - ndeyekupona kwemagetsi. Yedu FBD (DⅠ) yakatevedzana inoputika-humbowo inosiyana frequency motors inosanganisira yakavakirwa-mukati maRFI mafirita akatemerwa 4 kV yekuvhiya kusadzivirirwa uye yakadzivirirwa wiring yemukati inofambiswa kure nemagetsi anotungamira. Asi kusanganisa kunotadza kazhinji pane interface: isiriyo yekuisa pasi topology, isina kuvharidzirwa encoder tambo dzinomhanya dzakafanana kune mota inotungamira, kana VFD inotakura ma frequency akaiswa pamusoro pe8 kHz munzvimbo dzakavharirwa umo masaisai anoratidzwa anokwidziridza voltage spikes. Isu tinopa akazara ekumisikidza kits-kusanganisira ferrite cores, grounding lugs, uye 1: 1 yekuzviparadzanisa neshanduko yemaseketi emhinduro-kwete sekuwedzera, asi sezvikamu zvinosungirwa zveiyo system yakatarwa. Kana yekunatsa muShandong yakadzikisa isina kurongeka nguva ne73%, shanduko yanga isiri iyo mota pachayo. Kwanga kuri kumanikidza kudzika-imwe nzvimbo uye nekuisa yedu yekutanga-yakayedzwa gumi nemaviri-pulse rectifier sarudzo yekucheka THD pazasi 5% pamateshi emota.
Customization Iyo Isingakanganisi Chitupa
"Unogona here kuita kuti isaputika *uye* isingadziviriri *uye* inomhanya pa110°C ambient?" Hongu-asi chete kana nzira, kutonhora, uye zvitupa zvakabatana. Titanium housings inopikisa H₂S corrosion asi inofambisa kupisa zvisina kunaka; tinogadzirisa izvi nekubatanidza axial fin arrays uye kumanikidzirwa-mhepo ducting iyo inochengetedza T3 pamusoro pekushisa kunyange pa 100% mutoro mu55 ° C ambient. Kune mafeni edesulfurization anobata gasi rakanyorova reflue, tinobatirira epoxy-yakavharwa mamhepo emhangura *uye* tinotsanangudza masimbi esimbi asina zvitupa ane passivation zvitupa-kwete chete mamakisi egiredhi. Yese yetsika yuniti inoedzwa yakazara-mutoro wekupisa-muyedzo pa105% yakayerwa voltage kwemaawa makumi manomwe neshanu mukati meKirasi II Zone 1 yekamuri yekuyedza, ine thermographic yekutarisa maminetsi gumi nemashanu ega ega. Hapana nzira dzekudimbudzira. Hapana "yakaenzana" zvinhu. Hapana kunonoka kupihwa chitupa.
Kusarudza Zvakanaka Kunoreva Kubvunza Mibvunzo Yakarurama Kutanga
- Ndeipi yako chaiyo shoma yekushanda frequency? Kumhanya pazasi 20 Hz kunoda kutonhora kwakakosha-yedu yakaderera-kumhanya mamodheru anoshandisa ekunze anofuridza ane yakazvimirira simba, kwete shaft-yakaiswa mafeni anomira pazasi RPM.
- Ndeapi maharmonics anotonga grid yako? Kana yako saiti ine inorema arc choto mitoro, mota dzedu dzinosanganisira harmonic-tuned stator laminations kudzvinyirira 5th uye 7th odha resonance.
- Inofanirwa kutangazve nekukurumidza sei mushure mekubvisa kukanganisa? Coal mine ventilation inoda ≤3-second recovery-isu tinobatanidza capacitor mabhanga anochengetedza kunakidzwa kwemunda panguva ye micro-kukanganisa.
- Kuchengetedza kunoitika kupi? Yedu modular terminal mabhokisi anobvumira kuzara kwekudzivirira kudzivirira kuyedzwa pasina kuvhura iyo inodzivirira moto-yakakosha kana basa rinopisa richibvumidza kurambidza kupinda nguva.
Hatitengesi mota. Isu tinopa yakasimbiswa airflow assurance. Yese inoputika-isina kuputika frequency mota inosiya yedu Zibo nzvimbo ine traceable bvunzo mushumo unoratidza hapana-mutoro ikozvino kusaenzana (<2%), vibration amplitude (<1.8 mm / s RMS), uye tembiricha yepasi inokwira pasi pekuteedzera VFD waveform kusagadzikana. Ndiwo magadzirirwo anoitwa kuvimbika-kwete kuvimbiswa.
