Chotchinga chodzitetezera chodzipatula cha moto ndi utsi

Chiyambi

Chitetezo cha moto ndi kupewa moto ndizofunikira kwambiri kulikonse. Ndi zofunika kwambiri m'malo oopsa omwe amatha kupsa ndi kuphulika. Pankhaniyi, Chitetezo chamkati Zipangizo zodziwira moto ndi zotchinga zachitetezo zamkati ndizothandiza kwambiri. Machitidwe apaderawa adapangidwa kuti apewe moto ndi kuphulika. Amakwaniritsa izi mwa kuchepetsa mphamvu zamagetsi ndi kutentha mu chipangizo chodziwira moto.

Mfundo zazikulu:

nZipangizo zodziŵira moto zotetezeka mkati mwake ndi njira zofunika kwambiri zodzitetezera m'malo oopsa okhala ndi mpweya wophulika kapena zinthu zoyaka moto.

nZipangizo zapadera zamtunduwu zimachotsa zoopsa zomwe zingachitike poyatsa moto mwa kuchepetsa mphamvu zamagetsi zotenthetsera.

nM'magawo omwe ali pachiwopsezo chachikulu monga mankhwala a petrochemical, kupanga mankhwala, ndi kusungira zinthu zoopsa, ukadaulo uwu sungasinthidwe.

nKudziwa bwino makhalidwe ndi zochitika zoyenera za mitundu yosiyanasiyana ya masensa achitetezo chamkati ndi gawo lofunika kwambiri popanga njira yolondola yopewera moto.

nKugwira ntchito bwino kwa zida zowunikira zomwe zavomerezedwa ndi mabungwe apadziko lonse lapansi monga Atex zatsimikiziridwa mwalamulo.

Kodi chozimitsira moto chamkati chimagwira ntchito bwanji?

nM'malo oyaka moto komanso ophulika monga mafuta ndi gasi, mankhwala, ndi tirigu, zida zodziwira moto zachikhalidwe zimakhala zoopsa chifukwa cha kuthekera kopanga magetsi kapena kutentha kwambiri pamwamba, pomwe zida zodziwira chitetezo chamkati (IS) zimatsimikizira kuti zikugwira ntchito bwino m'malo oopsa kudzera mu kapangidwe kapadera.

nUkadaulo wake waukulu uli mu njira yochepetsera mphamvu: powongolera bwino mphamvu yamagetsi ndi kutentha mu dera, zimaonetsetsa kuti zida sizipanga zipsera zoyatsira moto kapena kutentha koopsa pansi pa mikhalidwe iliyonse yogwirira ntchito. Kuti akwaniritse cholinga ichi, dongosololi liyenera kukhala ndi chotchinga chachitetezo - chinthu chofunikira kwambiri chomwe chimayikidwa pakati pa chowongolera alamu ndi zida za IS, zomwe zimatha kuletsa kutumiza mphamvu zambiri ndikusunga mphamvu ya dera pansi pa malire achitetezo nthawi zonse.

nKapangidwe ka chitetezo kawiri aka (kuchepetsa mphamvu zamkati + chotchinga chakunja) kumapangitsa kuti chowunikira cha IS chikhale njira yodalirika kwambiri yowunikira moto m'malo omwe ali pachiwopsezo chachikulu, pomwe chikukwaniritsa miyezo yapadziko lonse lapansi yolimbana ndi kuphulika monga ATEX.

Kutsatira malamulo ndi miyezo ya zida zodziwonera moto zachitetezo ku UK

Ku UK, pali malamulo okhwima okhudza kugwiritsa ntchito zida zotetezera moto m'malo oopsa. Kutsatira malamulowa sikuti ndi lamulo lokha, komanso ndikofunikira kwambiri kuti anthu azigwira ntchito bwino komanso kuti zinthu ziziyenda bwino.

Malamulo ofunikira ndi Malamulo a AtexMalamulowa amachokera ku malangizo a EU omwe cholinga chake ndi kugwirizanitsa miyezo yachitetezo cha zida zomwe zimagwiritsidwa ntchito m'malo omwe kuphulika kungachitike.

Malamulo a ATEX ndi ofunikira kwa aliyense amene amapanga, kugulitsa, kapena kugwiritsa ntchito zida zotetezera m'malo omwe kuphulika kungachitike. M'madera oopsa mkati mwa European Union (kuphatikizapo UK), zida zonse ndi machitidwe oteteza ziyenera kutsatira malamulo a ATEX.

Kumvetsetsa ndi kutsatira malamulo awa n'kofunika kwambiri. Izi zimathandiza kuonetsetsa kuti pali chitetezo mukamagwiritsa ntchito zida zozimitsira moto m'malo oopsa.

Sankhani zotchinga zachitetezo zoyenera mkati

Ife, Beijing Pinghe, monga ogulitsa zotchinga zapamwamba kwambiri, tili ndi dongosolo lokonzekera lomwe cholinga chake ndi kuchepetsa kukula kwa zotchinga, kuzipangitsa kukhala zopepuka komanso zosavuta kugwiritsa ntchito, kupangitsa kuti kuyika kukhale kosavuta, kuchepetsa chiopsezo cha kulephera, komanso kupereka zotchinga zomwe zimagwirizana bwino ndi machitidwe opangira.

PHD-11TN-11 ndi PHD-22TN-1111 zathu zapangidwa kuti zigwiritsidwe ntchito ndi zida zowunikira utsi.

Kulowetsa chizindikiro cha zida zowunikira moto ndi utsi ndi zotchinga zodzitetezera zokha, zomwe zingapereke mphamvu yodzipatula kwa zida zowunikira moto m'malo oopsa. Zida zowunikira moto zimapanga zizindikiro za 0-40mA zomwe zimachotsedwa m'malo oopsa ndikutumizidwa kumadera otetezeka, zomwe zimagwira ntchito mu alamu ya utsi. Chogulitsachi chimayendetsedwa ndi dera lotulutsa ndipo ndi choyenera machitidwe a DCS/PLC omwe amagwiritsa ntchito kuzungulira.

Chogulitsachi sichifuna magetsi odziyimira pawokha, ndipo malo olowera ndi otulutsira magetsi amachotsedwa.
