Qhov zoo ntawm Explosion-proof Motors

1. Core kev nyab xeeb thiab tawg - pov thawj kev ua tau zoo

Tiv thaiv kev tawg tawg: Cov khoom pov thawj tawg yog tsim los nrog cov qauv tshwj xeeb kom ntseeg tau tias lawv tsis dhau los ua qhov hluav taws kub thaum ua haujlwm hauv qhov chaw muaj kev phom sij.

Cov ntaub ntawv pov thawj tawg (Ex d): Nws siv lub siab - lub zog tawg- pov thawj plhaub, uas tuaj yeem tiv taus qhov tawg hauv siab thiab tiv thaiv cov nplaim taws los ntawm kev sib kis mus rau sab nraud. Txawm hais tias muaj kev tawg hauv sab hauv, nws yuav tsis cuam tshuam rau sab nraud. cov

2. Ntau hom kev nyab xeeb (Ex e):Nyob rau hauv ib txwm ua hauj lwm tej yam kev mob, nws yuav tsis tsim arcs, sparks, los yog txaus ntshai heev kub, thiab ntxiv tshem tawm cov kev piam sij los ntawm kev txhim kho rwb thaiv tsev thiab kub nce. cov

Lwm hom: suav nrog hom zoo siab (tseem muaj lub siab zoo sab hauv los tiv thaiv cov nplaim hluav taws xob nkag mus), hom tsis muaj hluav taws xob (tsis cuam tshuam qhov sib tov thaum lub sijhawm ua haujlwm), thiab hom kev nyab xeeb ntawm sab hauv (kev txwv lub zog hluav taws xob), muab ntau yam kev nyab xeeb kev daws teeb meem rau ntau qib kev pheej hmoo. cov

3. Kev tswj qhov kub thiab txias:Forcefully txwv qhov saum npoo thiab sab hauv kub nce ntawm lub cev muaj zog kom paub meej tias nws tsis tshaj qhov kub ntawm qhov hluav taws kub ntawm ib puag ncig combustibles. Qee cov qauv tau nruab nrog cov ntsuas kub ntsuas los saib xyuas cov haujlwm ua haujlwm hauv lub sijhawm.

4. Cov qauv muaj zog thiab qib kev tiv thaiv

Lub casing ruaj khov thiab ruaj khov: Lub casing feem ntau yog ua los ntawm siab - lub zog, corrosion- cov ntaub ntawv tiv taus xws li cov hlau cam khwb cia hlau, cam khwb cia hlau, lossis stainless hlau, uas tuaj yeem tiv taus qhov kub siab tsim los ntawm kev tawg sab hauv (feem ntau ntau dua lossis sib npaug li 0.3MPa) tsis tawg lossis deforming. cov

5. Kev tiv thaiv siab:Kev tiv thaiv theem ntawm kev tawg loj heev- cov pov thawj motors feem ntau ncav cuag IP55 lossis siab dua (xws li IP65 / IP66), nrog cov plua plav thiab dej tsis zoo, haum rau kev ua haujlwm hnyav xws li cua sab nraum zoov, nag, plua plav, thiab lwm yam.

6. Precision sib koom nto tsim: Qhov sib koom ua ke ntawm txhua feem ntawm qhov tawg- pov thawj lub cev muaj zog yog cov tshuab precision, thiab qhov sib txawv thiab qhov ntev yog tswj nruj me ntsis. Qhov sib txawv qhov txias txias yog siv los tua cov nplaim taws uas tuaj yeem tawm. cov

7. Kev siv dav dav thiab kev txawj ntse

Kev hloov pauv ntau yam: siv dav hauv thaj chaw muaj kev phom sij xws li cov mines, roj thiab roj, tshuaj lom neeg, metallurgical, thiab kev ua qoob loo uas muaj cov pa tawg lossis plua plav, npog cov roj ib puag ncig hauv Cheeb Tsam 1, Zone 2, thiab plua plav ib puag ncig hauv Zones 20-22. cov

8. Kev ua haujlwm ruaj khov thiab txuag hluav taws xob:Qee cov series (xws li YBX3/YBX4) txais yuav F-chav tsev rwb thaiv tsev thiab raug soj ntsuam raws li B-chav kawm, tsis tshua muaj suab nrov thiab vibration, thiab siab -efficiency zog-txuag qauv muaj nqi zoo nyob rau hauv lub sij hawm ntev - ua haujlwm. cov

9. Kev soj ntsuam kev txawj ntse kev koom ua ke:Kev tawg tshiab-cov pov thawj lub cev muaj zog yog tsim los ntawm kev sib koom ua ke ntawm kev nyab xeeb thiab kev nkag siab zoo, kev sib koom ua ke ntawm kev vibration, kub, thiab rwb thaiv tsev raws li kev soj ntsuam sensor interfaces kom ua tiav kev nkag siab thiab kev saib xyuas ntawm kev ua haujlwm.

Core tsim lub tswv yim thiab cov qauv rau kev tawg-cov pov thawj motors

Explosion pov thawj lub cev muaj zog:

Lub tswv yim: Lub ntsiab lus nyob rau hauv "kev tiv thaiv tawg" es tsis yog "explosion resistance". Nws lub hom phiaj tsim yog cais lossis txwv cov hluav taws xob hluav taws xob, arcs, lossis siab - qhov kub thiab txias uas tuaj yeem tsim hauv lub cev muaj zog, kom lawv tsis txhob cuam tshuam cov pa taws, vapor, lossis plua plav ib puag ncig.

Cov qauv: Lub teb chaws thiab thoob ntiaj teb tawg- cov qauv pov thawj yuav tsum tau ua raws nruj me ntsis (xws li Suav GB 3836 series qauv, thoob ntiaj teb IEC 60079 series, North American NEC 500/505). Lub cev muaj zog yuav tsum tau txais ntawv pov thawj rau qhov sib thooj tawg - qib pov thawj (xws li Ex d IIC T4 Gb) thiab tau sau meej meej.

Ordinary lub cev muaj zog:

Lub tswv yim: Feem ntau yog tsom rau kev sib ntsib cov neeg kho tshuab, hluav taws xob, thiab kev ua haujlwm zoo, xws li lub zog, kev ceev, kev ua haujlwm zoo, qhov kub thiab txias, thiab lwm yam., tsis muaj kev tsim tshwj xeeb tiv thaiv rau qhov chaw tawg.

Standard: Ua raws li cov qauv kev ua tau zoo ntawm lub cev muaj zog thiab kev nyab xeeb, xws li IEC 60034 series, GB 755, thiab lwm yam, tab sis tsis muaj tawg - ntawv pov thawj.

Explosion pov thawj lub cev muaj zog: tseem ceeb kom zoo dua. Kev muaj peev xwm ua haujlwm nyab xeeb hauv qee qhov chaw muaj phom sij xws li tshuaj lom neeg, thee, thiab chaw nres tsheb roj yog ib qho yuav tsum tau ua kom muaj kev nyab xeeb ntawm lub neej thiab khoom.

Ordinary motors: siv nyob rau hauv qhov chaw muaj kev phom sij yog qhov teeb meem kev nyab xeeb loj, thiab cov nplaim taws lossis kub kub uas lawv tsim tuaj yeem ua rau muaj xwm txheej.

Kev tiv thaiv qib:

Kev tawg pov thawj lub cev muaj zog: feem ntau muaj qib IP tiv thaiv siab (xws li IP55, IP65 lossis siab dua), thiab tseem muaj qhov tawg- qib pov thawj (Ex qib).

Ordinary lub cev muaj zog: tsuas yog IP tiv thaiv qib, tsis muaj kev tawg- muaj peev xwm pov thawj.

Efficiency thiab kub nce:

Qhov kub nce txwv yog nruj dua (nws yuav tsum ua kom tau raws li T1-T6 pawg kub).

Ordinary motors: feem ntau tuaj yeem ua kom zoo dua hauv kev tsim kom ua tiav kev ua haujlwm siab dua, thiab kev tswj qhov kub thiab txias yog feem ntau raws li qib rwb thaiv tsev.

Kev ruaj ntseg:

Kev tawg pov thawj lub cev muaj zog: kev saib xyuas siab. Disassembly thiab sib dhos yuav tsum tau ua haujlwm tshaj lij, thiab kev ua kom huv thiab kev ncaj ncees ntawm qhov tawg - pov thawj nto yuav tsum tau ua kom ntseeg tau. Muaj cov kev cai nruj me ntsis ntawm tus lej thiab lub zog ntawm cov bolts fastening, thiab kev saib xyuas tsis raug yuav ua rau poob ntawm kev tawg- pov thawj kev ua haujlwm.

Ordinary lub cev muaj zog: Cov txheej txheem txij nkawm yog ib txwm niaj hnub thiab yooj yim.

Nqi thiab hnyav:

Kev tawg pov thawj lub cev muaj zog: Vim yog qhov nyuaj ntawm cov ntaub ntawv, cov txheej txheem, thiab cov ntawv pov thawj, tus nqi ntau dua li cov motors zoo tib yam ntawm tib lub zog, thiab qhov hnyav tau nce ntau.

Ordinary lub cev muaj zog: kev lag luam zoo thiab lub teeb yuag.

4. Daim ntawv thov scenarios

Explosion pov thawj lub cev muaj zog: Yuav tsum tau siv rau hauv qhov chaw muaj phom sij tawg.

Zone 1, Zone 2 (gas/vapor): Petrochemical, tshuaj, tshuaj tsuag, kev kho roj.

Zone 21, Zone 22 (dust): Hmoov zeb, khoom noj khoom haus, hlau plua plav Rhiav, thee mine.

Ordinary lub cev muaj zog: siv nyob rau hauv cov pa ib puag ncig yam tsis muaj explosive txaus ntshai.

Xws li cov chaw ua haujlwm zoo tib yam, cov twj tso kua dej, cov kiv cua, cov cuab yeej siv tshuab, siv conveyor, cov khoom siv hauv tsev, thiab lwm yam.

Cov lus qhia rau kev xaiv:

Lub hauv paus ntsiab lus tseem ceeb yog xaiv cov motors raws li kev faib cov cheeb tsam txaus ntshai ntawm qhov chaw teeb tsa. Nyob rau hauv txhua qhov chaw uas muaj cov xov xwm tawg, tawg - pov thawj motors ntawm qhov sib thooj tawg - pov thawj qib thiab hom yuav tsum raug xaiv, thiab cov motors zoo tib yam yuav tsum tsis txhob siv los hloov cov nqi, txwv tsis pub nws yuav ua rau muaj kev puas tsuaj loj. Hauv ib puag ncig zoo ib puag ncig, tus nqi ntau dua - lub cev muaj zog zoo tuaj yeem xaiv tau.

Qhov txuas hauv qab no yog peb qhov tawg - pov thawj lub cev muaj zog:
