Shenhai Explosion-Proof
Hom Flameproof:
Lub hauv paus ntsiab lus ntawm kev tiv thaiv tawg:
Lub hauv paus ntsiab lus ntawm kev tiv thaiv flameproof koom nrog siv lub explosion-proof casing uas withstands explosive quab yuam nyob rau hauv, tiv thaiv kev sib xyaw ntawm sab hauv kom tsis txhob kis mus rau ib puag ncig. Txhua qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob (nyob rau hauv cov txheej txheem xeem, qhov sib txawv loj tshaj plaws ntawm ob feem ntawm kev sib koom ua ke, uas yuav tsis ignite ib qho explosive sib tov sab nraud thaum qhov yooj yim tshaj rau ignite concentration ntawm ib tug tawg sib tov nyob rau hauv lub casing yog ignited). Yog hais tias cov roj combustible nkag mus rau hauv lub casing thiab ignites, ua rau muaj kev tawg, cov nplaim tawg muaj nyob rau hauv lub casing, tsis tuaj yeem ignite lwm cov khoom tawg, yog li ua kom muaj kev nyab xeeb ntawm ib puag ncig ib puag ncig.
Qhov zoo:
Flameproof enclosures yog dav siv nrog ib tug kuj yooj yim structural tsim.
Qhov tsis zoo:
Lawv yog cov loj thiab muaj cov kev cai tshwj xeeb rau cables, pob qij txha, cov kav dej, cov ntaub hauv ob sab phlu, thiab tes tsho (lub puab txoj kab uas hla ntawm cov roj hmab sealing nplhaib nyob rau hauv lub tes tsho yuav tsum phim lub tes tsho sab nraud txoj kab uas hla thiab yuav ruaj ntseg nrog ib tug compression txiv ntseej.; yog siv lub tes tsho steel yeeb nkab, lawv yuav tsum tau muab ntim nrog ntim raws li tau hais tseg; yog siv lub tes tsho tsis muaj cable, lub inlet yuav tsum raug kaw raws li tus qauv yuav tsum tau ua). Nws tsis raug tso cai qhib lub casing thaum muaj zog nyob rau hauv ib puag ncig txaus ntshai; qhib lub casing yuav tsum tau tshwj xeeb cov cuab yeej, thiab kev teeb tsa thiab kev saib xyuas tsis raug tuaj yeem ua rau muaj xwm txheej txaus ntshai. Flameproof enclosures tsis raug tso cai hauv Zone 0 thiab feem ntau yog siv rau cov motors, teeb pom kev zoo, lwm.
Intrinsically Safe Hom:
Lub hauv paus ntsiab lus ntawm kev tiv thaiv tawg:
Intrinsically nyab xeeb, los yog “Kev nyab xeeb ntawm sab hauv,” hais txog lub hauv paus ntsiab lus ntawm kev tiv thaiv tawg qhov twg lub zog ntawm hluav taws xob sparks los yog thermal cuam tshuam uas tsim nyob rau hauv ib tug ntaus ntawv los yog nws raug kev sib txuas xov hlau yog txwv rau ib theem uas tsis tuaj yeem ignite. Qhov no txhais tau hais tias nyob rau hauv ib txwm ua hauj lwm los yog tej yam kev ua txhaum cai, tsis muaj npe tawg sib tov tau ignited. Cov kev tiv thaiv tseem ceeb suav nrog kev txwv qhov hluav taws xob thiab qhov hluav taws xob tam sim no thiab Circuit Court capacitance thiab inductance, faib ua Typeia (cia ob lub ntsiab lus txhaum) and Type ib (cia ib qho txhaum).
Qhov zoo:
Cov khoom siv tsis tas yuav tsum muaj cov kab tshwj xeeb, ua kom muaj kev nyab xeeb rau cov neeg ua haujlwm tswj xyuas thiab kho, thiab cov npog tuaj yeem qhib thaum muaj hluav taws xob.
Qhov tsis zoo:
Nws tsis haum rau cov khoom siv hluav taws xob siab thiab feem ntau yog siv rau cov khoom siv hluav taws xob tsawg hauv kev ntsuas, tswj, thiab kev sib txuas lus. 'Ib’ hom tuaj yeem ua haujlwm hauv Zone 0; 'Ib’ hom tuaj yeem ua haujlwm hauv Zone 1.
Hom Siab Zoo:
Lub hauv paus ntsiab lus ntawm kev tiv thaiv tawg:
Lub hauv paus ntsiab lus ntawm zoo siab hom tawg tiv thaiv muaj qhia cov huab cua ntshiab los yog inert gas ntawm ib tug tej yam siab rau hauv lub enclosure, tiv thaiv combustible gases nkag mus thiab, li no, tiv thaiv cov khoom siv hluav taws xob los ntawm kev tiv thaiv cov pa hluav taws xob tawg, yog li no tiv thaiv kev tawg. Cov kev ntsuas tseem ceeb rau cov cuab yeej siv hluav taws xob muaj xws li kev tswj xyuas cov roj tiv thaiv (huab cua ntshiab los yog inert gas) siab nyob rau hauv lub casing ntau dua 50 Pascals. Kev xav tau rau cov khoom siv hluav taws xob siab muaj xws li: lub casing, cov kav dej, thiab lawv cov kev sib txuas yuav tsum tiv taus 1.5 lub sij hawm lub siab tshaj plaws zoo siab nrog rau tag nrho cov pa ports kaw nyob rau hauv ib txwm ua hauj lwm tej yam kev mob raws li teev los ntawm cov chaw tsim tshuaj paus, nrog qhov siab tshaj plaws ntawm 200Pa. Kev tiv thaiv huab cua yuav tsum nyob hauv thaj chaw tsis muaj kev phom sij, dawb ntawm corrosive media; tso pa tawm yuav tsum nyob rau hauv qhov chaw tsis muaj kev phom sij, los yog spark thiab particle cais baffles yuav tsum tau txiav txim siab; cov khoom siv uas saib xyuas huab cua siab thiab ntws yuav tsum tau teeb tsa raws li cov khoom npe lossis phau ntawv qhia tshwj xeeb.
Qhov zoo:
Yuav siv tau thaum lwm txoj kev tsis siv tau.
Qhov tsis zoo:
Installation thiab txij nkawm yog complex thiab kim; yog instrumental nplaim taws sib tov, lwm yam kev tiv thaiv yuav tsum tau ua; tsis pub muaj lub zog npog ua haujlwm. Feem ntau siv rau cov motors loj, transformers, thiab high-voltage switches. Tso cai siv ntau yam: Cov cuab yeej siv hluav taws xob tsis siv neeg tuaj yeem siv rau hauv Zone 1; Cov cuab yeej siv nrog kev ua haujlwm acoustic-optic tswb tuaj yeem siv hauv Zone 2.
Tam sim no, peb lub tuam txhab cov khoom tawg-pov thawj feem ntau suav nrog flameproof, intrinsically nyab xeeb, thiab hom pressurized. Txawm li cas los xij, Lub hauv paus ntsiab lus yog los tiv thaiv cov khoom siv hluav taws xob los ntawm kev ua qhov hluav taws kub. Txoj kev yooj yim tshaj plaws los tiv thaiv kev tawg yog los xyuas kom meej tias peb lub ntsiab lus ntawm combustion - roj, oxidizer, thiab qhov hluav taws xob hluav taws xob-tsis nyob hauv lub sijhawm thiab qhov chaw. Tom qab xav txog ntau yam kev ua haujlwm, hom khoom tawg-pov thawj hluav taws xob tsim nyog tshaj plaws yuav tsum raug xaiv, coj mus rau hauv tus account tus nqi thiab yooj yim ntawm kev saib xyuas, kom txo tau qhov kev pheej hmoo ntawm kev phom sij ntawm qhov chaw.
