Kev paub txog kev tawg-pov thawj motors
1. Hom qauv ntawm lub cev muaj zog tawg
Tswv yim:Lub npe hu ua explosion-proof motor yog hais txog lub cev muaj zog uas siv qee qhov kev ntsuas tawg los xyuas kom meej tias nws tuaj yeem siv tau zoo nyob rau hauv qhov chaw tawg-tshuaj lom.
Kev tawg-pov thawj lub cev muaj zog tuaj yeem muab faib ua peb hom hauv qab no lossis lawv cov hom sib xyaw ua ke raws li lawv cov hauv paus ntsiab lus ntawm kev ua tau raws li qhov yuav tsum tau ua kom tawg:
1. Flameproof hom, B hom
Lub cev muaj zog uas tsis ua rau muaj kev tawg ntawm qhov sib xyaw ua ke ntawm lwm qhov tawg thaum muaj kev tawg hauv lub cev muaj zog.Lub cev muaj zog lub cev muaj zog txaus (qib qib cam khwb cia hlau, steel phaj raws li lub casing), kom nws tuaj yeem tiv taus qhov tawg siab thiab cuam tshuam sab nraud yam tsis muaj kev puas tsuaj; Cov qauv tsis sib xws (qhov sib txawv thiab qhov ntev) ntawm cov nplaim hluav taws sib txuas; cov kev xav tau rau cov thawv sib txuas, cov khoom siv hlau nkag, thiab lwm yam.; tswj qhov kub ntawm lub plhaub saum npoo kom nws tsis tuaj yeem ncav cuag qhov kub thiab txias.
2. Ntau hom kev nyab xeeb, hom A
Kev sib khi ntawm lub cev muaj zog yog qhov zoo dua, thiab kev tiv thaiv qib yuav tsum tau txais IP55; electromagnetic tsim yuav tsum txiav txim siab txo qhov kub nce; lub sij hawm thaum lub rotor nce mus txog qhov kub thiab txias thaum nws raug kaw, thiab yog nruab nrog lub tshuab hluav taws xob tswj tus kheej; txhim kho qhov tig-rau-tig, hauv av-rau-hauv av thiab theem-rau-theem kev sim ntawm winding rwb thaiv tsev voltage; txhim kho kev ntseeg tau ntawm kev sib txuas ntawm tus neeg xyuas pib; tswj qhov tsawg kawg nkaus unilateral clearance ntawm stator thiab rotor.Nyob rau hauv luv luv, nws tiv thaiv kev huam yuaj, arcs los yog txaus ntshai kub los ntawm cov qauv thiab hluav taws xob, yog li txhim kho kev ruaj ntseg ntawm kev ua hauj lwm.
3. Hom siab zoo, P hom
Lub cev muaj zog tawg-pov thawj uas txhaj cov huab cua zoo rau hauv lub tsev lossis ua rau nws nrog cov pa roj tsis zoo (xws li nitrogen) txhawm rau tiv thaiv cov khoom tawg sab nraud los ntawm kev nkag mus rau lub cev muaj zog.
Scope ntawm kev siv:Flameproof thiab zoo siab hom yog haum rau txhua qhov chaw muaj kev phom sij, thiab cov hluav taws xob tsis zoo (Type B) yog siv dav hauv Suav teb.Tus nqi tsim khoom thiab tus nqi ntawm qhov nce kev nyab xeeb lub cev muaj zog yog qis dua li cov hom flameproof, thiab tsuas yog haum rau Zone2 qhov chaw.
2. Kev faib tawm ntawm cov motors hauv cov pa cua tawg
1. Raws li kev faib tawm ntawm qhov chaw tawg
| Kev faib tawm ntawm qhov chaw tawg | cheeb tsam0 | District1 | Zone2 |
| Ntau zaus thiab lub sijhawm ntawm cov pa cua tawg | Cov chaw uas cov pa cua tawg tshwm sim tsis tu ncua lossis muaj nyob rau lub sijhawm ntev | Qhov chaw uas muaj cov pa cua tawg tuaj yeem tshwm sim thaum lub sijhawm ua haujlwm ib txwm muaj | Thaum lub sijhawm ua haujlwm ib txwm muaj, nws tsis tuaj yeem muaj qhov chaw tawg tawg, lossis qhov chaw uas nws tshwm sim qee zaus thiab tsuas muaj nyob rau lub sijhawm luv. |
2. Raws li hom khoom tawg
| huab cua tawg Kev faib tawm ntawm cov khoom siv hluav taws xob | Chav kawm I Cov Khoom Siv Hluav Taws Xob rau Coal Mine | Chav II Cov khoom siv hluav taws xob rau cov pa cua tawg uas tsis yog cov mines | ||
| II A | II B | II C | ||
| Siv tau roj ib puag ncig | methane | Ntau tshaj 100 hom toluene, methanol, ethanol, diesel, thiab lwm yam. | Ze li 30hom ntawmethylene, gas, thiab lwm yam. | Hydrogen, acetylene, carbon disulfide, thiab lwm yam. |
3. Muab faib raws li qhov kub thiab txias ntawm cov roj tawg
| kub pawg | Qhov siab tshaj qhov kub thiab txias ° C | hom xov xwm |
| T1 | 450 | Toluene, Xylene |
| T2 | 300 | Ethylbenzene, lwm. |
| T3 | 200 | Diesel, lwm. |
| T4 | 135 | Dimethyl etherlwm. |
| T5 | 100 | carbon disulfide thiab lwm yam. |
| T6 | 85 | Ethyl nitrite, lwm. |
3. Cov cim qhia txog kev tawg-pov thawj motors
1. Piv txwv ntawm cov khoom tawg-pov thawj rau flameproof peb-theem asynchronous motors:
ExDI flameproof lub cev muaj zog rau thee mine
ExD IIBT4 Hoobkas IIBod T4 pawg xws li: tetrafluoroethylene qhov chaw
2. Piv txwv ntawm kev tawg-pov thawj cov cim rau kev ruaj ntseg peb-theem asynchronous motors:
ExE IIT3 muaj feem xyuam rau qhov chaw uas qhov kub thiab txias yog T3 pab pawg flammable gas hauv lub Hoobkas
4. Peb qhov yuav tsum tau muaj ntawv pov thawj rau kev tawg-pov thawj motors
Thaum lub cav tawg-pov thawj tawm ntawm lub Hoobkas, qhov kev ua tau zoo yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm cov kev cai thiab cov qauv, thiab nws tseem yuav tsum tau txais peb daim ntawv pov thawj uas tau muab los ntawm cov tuam haujlwm tseem ceeb ntawm lub xeev. Daim ntawv tsav tsheb yuav tsum qhia peb daim ntawv pov thawj tus lej, uas yog:
1. Daim ntawv pov thawj tawg
2. tawg-pov thawj lub cev muaj zog ntau lawm daim ntawv tso cai naj npawb
3. Daim ntawv pov thawj kev nyab xeeb MA naj npawb.
Yuav tsum muaj lub cim EX liab nyob rau sab xis sab xis ntawm daim ntawv tsav tsheb thiab ntawm lub hau npog ntawm lub qhov hluav taws xob.
