Hluav taws xob Actuator
Ib nrab-tig hluav taws xob valve actuators yog siv rau li qub nrog ib feem tig ntawm lub valve disc, xws li pob li qub, npauj npaim li qub, ntsaws li qub thiab lwm yam.
Part-tig tawg-pov thawj hluav taws xob valve actuators muab faib ua ob pawg ntawm QB.
Torque ntau ntawm QB series yog: 125 ~ 4000N.m (50 ~ 2000N.m rau hom adjustable); (4000 ~ 16000N.m rau hom modulating): ob cov khoom no tau muab faib ua hom zoo tib yam thiab hom modulating raws li kev tswj hluav taws xob sib txawv. Cov hluav taws xob tawg-pov thawj hluav taws xob valve actuators tau tsim-hauv cov kev tswj hwm yooj yim xws li mob stroke thiab lub zog, thiab lub thawv tswj yuav tsum tau paub txog qhov chaw thiab chaw taws teeb tswj ntawm lub valve. Cov ntsuas ntsuas ua tau raws li qhov yuav tsum tau ua ntawm GB / T24922-2010 "Technical Conditions for Explosion-proof Electric Valve Actuators."
Ntxiv nrog rau cov kev tswj hwm hauv paus xws li mob stroke thiab torque, cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob tseem ceeb kuj tau nruab nrog cov khoom tswj xws li tswj modules thiab AC contactors. Nws tuaj yeem txuas ncaj qha mus rau cov khoom siv hluav taws xob kom paub txog qhov chaw ua haujlwm ntawm lub valve, thiab tuaj yeem ncaj qha tau txais cov teeb liab tso tawm los ntawm DCS tswj qhov system kom paub txog cov chaw taws teeb tswj kev ua haujlwm ntawm lub valve. Cov ntsuas ntsuas ua tau raws li qhov yuav tsum tau ua ntawm GB / T 24922-2010 "Technical Conditions for Flameproof Electric Valve Actuators". Lub flameproof regulating hluav taws xob valve actuators yog tsim rau lub kaw-voj tswj system ntawm qhuav industrial txheej txheem, thiab muaj peev xwm ua tau qhov chaw ntawm lub valve los ntawm kev tau txais 4 ~ 40mA tam sim no teeb liab xa los ntawm cov tswj system. Cov ntsuas ntsuas ua tau raws li qhov yuav tsum tau ua ntawm GB/T24922-2010 "Technical Conditions for Flameproof Electric Valve Actuator" thiab JB/T8219-2016 "Ordinary and Intelligent Electric Actuators for Industrial Process Control Systems".

Vim li cas thiaj muaj kev tawg?
Kev tawg yog thaum ib yam khoom dheev hloov ntawm ib lub xeev mus rau lwm qhov los ntawm kev hloov pauv ntawm lub cev lossis tshuaj, tso tawm ntau lub zog. Lub zog tso tawm ntawm tus nqi nrawm yuav ua rau muaj kev kub ntxhov thiab kev puas tsuaj rau cov khoom nyob ib puag ncig.
Muaj peb yam tsim nyog rau kev tawg: cov khoom tawg, oxygen, thiab qhov hluav taws kub. Objectively, ntau qhov chaw ua haujlwm ua tau raws li cov xwm txheej rau kev tawg. Thaum qhov concentration ntawm cov khoom tawg thiab cov pa oxygen nyob rau hauv qhov kev txwv tawg, qhov tawg yuav tshwm sim yog tias muaj qhov tawg.
Txhawm rau tiv thaiv kev tawg, peb yuav tsum xav txog peb yam tsim nyog saum toj no. Yog tias peb txwv ib qho ntawm cov xwm txheej tsim nyog, peb yuav txwv qhov tawg.
Cov khoom siv hluav taws xob kuj yog qhov muaj peev xwm tiv thaiv hluav taws xob, uas tuaj yeem ua rau qhov kub thiab txias nce, qhov paug tawm zoo li qub lossis lub txim taws tshwm sim los ntawm tam sim no tam sim no thaum lub tshuab ua haujlwm. Los ntawm qhov tsim ntawm qhov pom, cov khoom siv hluav taws xob tsis muaj hluav taws xob tuaj yeem thaiv cov khoom tawg tawg hauv lub plhaub, uas yog tshwj xeeb tshaj yog muaj zog thiab tuaj yeem tiv taus qhov tawg siab ntawm cov khoom tawg hauv cov khoom sib xyaw thiab tiv thaiv cov khoom tawg los ntawm kev sib kis mus rau sab nraud ntawm lub plhaub. Yog li ntawd, cov khoom siv hluav taws xob flameproof tuaj yeem tiv thaiv kom dhau los ua qhov muaj peev xwm ignition.
Hom hluav taws xob tawg-pov thawj hluav taws xob no tuaj yeem tiv taus qhov tawg ntawm cov hluav taws xob sib xyaw uas tau nkag mus rau hauv lub plhaub yam tsis muaj kev puas tsuaj, thiab yuav tsis cuam tshuam cov khoom siv hluav taws xob hauv lub plhaub sab nraud uas tsim los ntawm ib lossis ntau dua gases lossis vapors los ntawm kev sib koom ua ke. nto los yog qhov ntawm lub plhaub.
