Shenhai Explosion-Proof
Tawg-Proof Types:
Tus tawg-profo txoj kev uas muaj kev ruaj ntseg (Ex e) taws (Ex d d) enclosures txawv ho.
Flameproof hom:
Tus flameproof txoj kev yuav enclosing qhov chaw uas tej zaum yuav ua arcs los yog sparks thaum lub lag luam nyob rau hauv ib robust enclosure. No enclosure nrogstands tawg pressures tsis puas tsuaj, Ensuring tias taws thiab yus muaj peevxwm generated los ntawm ib tawg hauv tsis hloov sab nraum zoov. Nws xyuas kom meej tias cov no yog extinguished thiab txias li kis los ntawm cov flameproof ob leeg, tiv thaiv ignition ntawm explosive gases sab nraum lub enclosure.
Muaj kev ruaj ntseg ntau yam:
nyob rau hauv muaj kev ruaj ntseg (Ex e) enclosures, Yog tsis muaj ntau lawm sparking los yog yus kub thaum lub lag luam muaj peevxwm. Ntxiv kev ntsuas noj kom txhim khu kev ruaj ntseg thiab reliability.
Screws:
Vim li cas muaj coob screws hauv taws enclosures, Tab sis tsis muaj kev ruaj ntseg ntau zog?
Flameproof enclosures yuav tsum tau ib theem ntawm precision nyob rau hauv lawv kis kam rau ua kom tiv thaiv explosions ntawm igniting lwm explosive gases. Ntau screws xyuas tighter seams thiab ntau dua kev ruaj ntseg. Qhov no yog vim li cas flameproof enclosures muaj heev screws heev.
Muaj kev ruaj ntseg tsom rua kev ruaj ntseg tsom rua theem tiv thaiv. Sealing zoo uas nyuam qhuav plaub screws yog txaus.
Components:
Flameproof enclosures yuav tsis txwv txog cov components thoob ntiaj teb vim lawv yuav to taub tej arcs los yog sparks hauv. Tsuav tus outer plhaub yuav to taub lub tawg siab tsis puas tsuaj, Nws xyuas kom meej tias taws thiab muaj peevxwm generated hauv yog extinguished thiab txias thaum kis los ntawm cov flameproof ob leeg, tiv thaiv lwm ignition.
Muaj kev ruaj ntseg enclosures yuav tsum xub xyuas kom meej tias internal li tsis ua sparks, kub thiab txias, arcs. Ntxiv tiv thaiv kev ntsuas ces coj los txhim khu kev ruaj ntseg thiab reliability.
Compatibility:
piv txwv li, Ib circuit breaker tsim rau ib flameproof enclosure tsis tau siv nyob rau hauv ib qho kev ruaj ntseg enclosure. tiam sis, converting kev ruaj ntseg enclosure rau ib flameproof ib permissible.
Yog li ntawd, vim, Qhov tsim nyog ntawm explosion-proof enclosure yuav tsum tau xaiv raws li qhov uas yuav tsum tau ua, Thiab substitutions yuav tsum tsis txhob ua xws li casually.
