Explosion-proof Qhov sib txawv zaus lub cev muaj zog tsis xaiv tau hauv cov nroj tsuag tshuaj, thee mines, lossis roj refineries - lawv yog qhov sib txawv ntawm kev ua haujlwm tas mus li thiab kev puas tsuaj loj. Peb tau pom cov chaw poob peb qhov kev hloov pauv ntawm kev tsim khoom vim tias lub kiv cua lub cev muaj zog poob thaum lub sijhawm kuaj pom cov pa tsis zoo. Lwm tus tau hloov tus qauv VFDs ob zaug hauv 18 lub hlis - tsuas yog txhawm rau tshawb pom qhov laj thawj tsis yog software tuning lossis cable shielding, tab sis qhov tseem ceeb tsis sib haum xeeb ntawm cov chav kawm hluav taws xob hluav taws xob, qhov ntsuas qhov ntsuas, thiab lub luag haujlwm ntawm lub ntiaj teb. Ntawm Zibo Hongcheng Ntxuam Co., Ltd., peb tsim hluav taws xob tawg-pov thawj lub cev muaj zog tsis yog cov khoom siv nyob ib leeg, tab sis raws li kev sib xyaw ua ke ntawm cov cua ntws tswj cov nodes-engineered los ntawm winding mus rau vaj tse rau ib txhij ua raws li GB 3836.1-2021 (Tuam Tshoj tus Ex txuj), IEC 60079 kev muaj xws li-V0D kev cai. 519-2022 harmonic txwv.
Vim li cas Standard VFD Motors tsis ua haujlwm hauv thaj chaw muaj kev phom sij - Txawm tias "Ex" Cov ntawv lo
Ntau tus neeg siv xav tias daim ntawv lo "explosion-proof" guarantees VFD kev nyab xeeb. Tsis yog. Lub cev muaj zog tau ntawv pov thawj rau qhov zoo li qub Ex d IIB T4 tej zaum yuav overheat nyob rau hauv 30 Hz PWM voltage kev ntxhov siab, degrading Class H rwb thaiv tsev sai dua thermal qauv kwv yees. Peb tau ntsuas rotor nto qhov kub thiab txias ntawm 42 ° C saum lub npe phaj ntawm 25 Hz nyob rau hauv qhov chaw kaw qhov chaw - txaus rau carbonize cov kua roj vanish thiab ua rau hauv av faults. Qhov phem tshaj: non-sinusoidal waveforms nce eddy tam sim no poob nyob rau hauv flameproof enclosures, nce saum npoo kub tshaj T-rating margins. Tias yog vim li cas peb qhov tawg-pov thawj qhov sib txawv zaus lub cev muaj zog pib nrog dual-certified stator windings-Class H rwb thaiv tsev * ntxiv rau cov hlua txuas ntxiv resistant rau siab dv / dt transients-thiab vaj tsev machined rau ± 0.05 hli concentricity los tiv thaiv cov kabmob tam sim no los ntawm hom-hom voltage.
Kev Sib Koom Tes Hauv Ntiaj Teb Tiag: Yam Koj Tus Kws Ua Haujlwm Tswj Xyuas Yuav Tsum Paub
VFD compatibility tsis yog hais txog torque nkhaus-nws yog hais txog electromagnetic survivability. Peb FBD(DⅠ) series tawg-pov thawj kuj sib txawv zaus motors suav nrog built-in RFI cov ntxaij lim dej ntsuas rau 4 kV surge tiv thaiv kab mob thiab tiv thaiv sab hauv thaiv kev tawm ntawm lub hwj chim ua. Tab sis kev koom ua ke tsis ua haujlwm feem ntau ntawm qhov sib cuam tshuam: tsis raug grounding topology, unshielded encoder cables khiav parallel mus rau lub cev muaj zog, los yog VFD cab kuj frequencies teem siab tshaj 8 kHz nyob rau hauv confined qhov chaw uas reflected nthwv dej amplify voltage spikes. Peb muab tag nrho cov khoom siv ua haujlwm-xws li ferrite cores, grounding lugs, thiab 1: 1 cais transformers rau kev tawm tswv yim circuits-tsis yog add-ons, tab sis raws li qhov yuav tsum tau ntawm cov txheej txheem specification. Thaum lub refinery nyob rau hauv Shandong txo downtime downtime los ntawm 73%, qhov kev hloov tsis yog lub cev muaj zog nws tus kheej. Nws tau tswj hwm ib lub ntsiab lus hauv av thiab txhim kho peb qhov kev sim ua ntej 12-pulse rectifier xaiv los txiav THD qis dua 5% ntawm lub cev muaj zog terminals.
Customization uas tsis cuam tshuam daim ntawv pov thawj
"Koj puas tuaj yeem ua kom nws tawg-pov thawj * thiab * corrosion-resistant * thiab * khiav ntawm 110 ° C ambient?" Yog-tab sis tsuas yog cov khoom siv, cua txias, thiab cov ntawv pov thawj txoj kev sib haum. Titanium vaj tse tiv thaiv H₂S corrosion tab sis ua cua sov tsis zoo; peb daws qhov no nrog kev sib xyaw axial fin arrays thiab yuam-cua ducting uas tswj T3 qhov kub thiab txias txawm tias ntawm 100% load hauv 55 ° C ambient. Rau cov kiv cua desulfurization tuav cov roj ntub dej, peb kos epoxy-coated tooj liab windings * thiab * qhia cov stainless hlau fasteners nrog passivation daim ntawv pov thawj - tsis yog cov cim qib. Txhua chav tsev kev cai raug kuaj xyuas tag nrho ntawm 105% qhov ntsuas hluav taws xob rau 72 teev hauv peb chav kuaj II Zone 1, nrog ntsuas ntsuas ntsuas txhua 15 feeb. Tsis muaj shortcuts. Tsis muaj "sib npaug" cov ntaub ntawv. Tsis muaj ntawv pov thawj rov qeeb.
Xaiv txoj cai txhais tau tias nug cov lus nug zoo ua ntej
- Koj qhov tsawg kawg nkaus ua haujlwm zaus yog dab tsi? Khiav qis dua 20 Hz xav tau qhov txias txias tshwj xeeb - peb cov qauv qis qis siv cov tshuab hluav taws xob sab nraud nrog lub zog ywj pheej, tsis yog cov kiv cua kiv cua uas nres ntawm qis RPM.
- Dab tsi harmonics dominate koj daim phiaj? Yog tias koj qhov chaw muaj qhov hnyav arc rauv loads, peb cov motors muaj xws li kev sib haum xeeb-tuned stator laminations kom suppress 5th thiab 7th resonance.
- Nws yuav tsum tau rov pib sai npaum li cas tom qab kev tshem tawm qhov txhaum? Coal mine qhov cua yuav tsum tau ≤3-thib ob rov qab-peb koom ua ke cov tsev txhab nyiaj capacitor uas tswj kev ua kom muaj zog thaum muaj kev cuam tshuam me me.
- Kev saib xyuas nyob qhov twg? Peb lub thawv modular davhlau ya nyob twg tso cai rau kev ntsuas kev tiv thaiv tag nrho yam tsis tau qhib qhov sib koom ua ke-tseem ceeb thaum ua haujlwm kub tso cai txwv lub sijhawm nkag.
Peb tsis muag cov motors. Peb xa cov ntaub ntawv pov thawj airflow. Txhua qhov tawg-pov thawj qhov sib txawv ntawm lub cev muaj zog tawm ntawm peb qhov chaw Zibo nrog cov ntaub ntawv kuaj pom uas tsis muaj qhov tsis txaus ntseeg tam sim no (<2%), kev vibration amplitude (<1.8 mm / s RMS), thiab qhov kub thiab txias nce nyob rau hauv simulated VFD waveform kev ntxhov siab. Qhov ntawd yog li cas kev ntseeg tau raug tsim kho - tsis tau cog lus. Mus saib https://www.honghengfan.com rau cov ntaub ntawv kev tshaj lij, cov ntawv sau npe ntawm VFD-lub cev muaj zog sib piv, thiab nkag mus ncaj qha rau daim ntawv thov engineers uas tau teev ntau tshaj 2,100 qhov teeb meem-chaw teeb tsa txij li xyoo 2020.
