Shenhai Explosion-Proof
Explosion-proof khoom muaj stringent yuav tsum tau wiring, cable siv, thiab hauv pem teb, txawv ntawm cov khoom hluav taws xob.
Tam sim no peev xwm
Rau aav 1 Thiab 2, Lub permissible tam sim no nqa peev xwm ntawm tus cwjpwm hauv lub explosion-proof thawv yuav tsum tsis muaj tsawg tshaj li 1.25 Lub sij hawm nyob tam sim no ntawm lub caij fuse thiab cov nyob tam sim no ntawm lub circuit breaker tus ntev-qeeb overcurrent tso tawm. Rau ceg circuits uas tsis muaj voltage cage asynchronous motors, Lub peev xwm tam sim no yuav tsum tsis muaj tsawg tshaj li 1.25 Lub sij hawm lub cev muaj nyob tam sim no.
Hlau siv ntaub ntawv xaiv tsa
Tsis pub dhau lub tawg-risk tsam qib 2, Hwj huam mov kab yuav tsum siv aluminum tub ntxhais wires los yog cables nrog ib cross-seem ntawm 4mm² los yog loj, Thaum lighting circuits yuav siv tau ib tug ntoo khaub lig-seem ntawm 2.5m². nyob rau hauv explosive ib puas tsuaj rau ib theem 1, Tis circuits yuav tsum siv tooj liab wires los yog cables. Nyob rau tej qho chaw uas tseem ceeb vibration, Tso tseg tooj liab yooj ywm wires los yog cables yuav tsum tau xaiv. Siv aluminum tub ntxhais cables tsis tso cai rau thee mine shafts.
Circuit Court Sib Txuas
Thaum opting rau aluminum tub ntxhais cables los yog wires, txhim khu kev qha rau cov pob qij txha 1 Cov circuits hluav taws xob yog tsim nyog nyob rau hauv lub cheeb tsam tawg-proof box. rau tsam 2, Cov pob qij txha no yuav tsum tsis pub dhau los yog nyob ze ib lub thawv rau ntawm tej cheeb tsam uas tsis muaj teeb meem. Explosion-proof junction boxes yog pom zoo rau tsam 1, Pliag muaj kev ruaj ntseg lub thawv yog suitable rau tsam 2.
Rho tawm thiab sealing
Thaum pw hluav taws xob kab hauv trenches los yog conduits, thiab hla ntawm phab ntsa los yog pem teb sib cais uas txawv explosion uas yuav muaj ntau theem, yuav tsum siv cov ntaub ntawv uas tsis yog-combustible yuav tsum siv rau sealing.
Xaiv qhov chaw nruab nrab, nteg qe, tsim nyog, thiab sib txuas rau txoj kev sib txuas tawg-proof fais fab tuag Circuits raws li tej theem uas yuav raug. Qhov chaw ntawm explosion-proof fais fab hluav taws xob yuav tsum xav pw hluav taws xob kab nyob rau tej thaj chaw uas txo qis los yog ntxiv los ntawm qhov chaw leak.
Saum toj no yog ib nyuag overview ntawm txoj kev tiv thaiv hluav taws xob wires hauv explosion-proof thawv. Tej yam kev xav yuav tsum tau raws li muaj tshwm sim. Explosion-proof thawv muaj cable glands thiab compression screws rau lub outgoing cables. Ensuring kev ruaj ntseg yuav kis tau lub cable los ntawm cov gland thiab compression screw, zawm nws ces cov txee kaw cov kis nyob ib ncig ntawm lub cable tawm, Tiv thaiv tej sparks ntawm escaping.
