Hluav taws xob Actuator
Nws txhim kho kev nyab xeeb kev ua haujlwm thiab nce kev tiv thaiv kev ua haujlwm
Cov hluav taws xob tawg-pov thawj hluav taws xob tuaj yeem tiv taus qhov tawg ntawm cov hluav taws xob sib xyaw uas tau nkag mus rau sab hauv ntawm lub casing yam tsis muaj kev puas tsuaj, thiab yuav tsis cuam tshuam cov roj uas tsim los ntawm ib lossis ntau dua gases lossis vapors los ntawm ib qho chaw sib koom lossis qhov ntawm lub casing. Cov khoom siv hluav taws xob enclosures rau sab nraud explosive atmospheres
Qhov tawg yog dab tsi?
Qhov yuav tsum tau ua ua ntej ua rau muaj kev tawg yog tias cov khoom tawg yuav tsum tau tov nrog oxygen rau qee qhov thiab ua rau muaj tshuaj lom neeg nyob rau hauv qhov tsim nyog ignition. Yog tias cov tshuaj tiv thaiv ceev tshaj qhov ceev ntawm lub suab, nws txhais tau tias yog qhov tawg. Cov khoom tawg tawg uas tau sau rau qee qhov tawg sai sai thiab ua rau muaj kev puas tsuaj rau hauv daim ntawv ntawm cov nthwv dej tawg.
Dab tsi yog qhov tawg-pov thawj?
Ib qho ntawm peb yam xwm txheej saum toj no yog txwv tsis pub tshwm sim, thiab kev tawg tuaj yeem tiv thaiv tau. Hauv ntau qhov chaw thov, muaj cov khoom tawg thiab cov pa oxygen yog qhov tsis tuaj yeem zam tau, yog li cov khoom siv hluav taws xob yuav tsum raug txwv. Cov khoom siv hluav taws xob yog qhov muaj peev xwm ntawm qhov hluav taws kub. Thaum lub tshuab ua haujlwm, nws yuav ua rau qhov kub thiab txias ntawm qhov chaw, qhov hluav taws xob zoo li qub lossis hluav taws xob hluav taws xob tshwm sim los ntawm tam sim no tam sim no. Nyob rau hauv cov nqe lus ntawm kev tsim, cov khoom siv hluav taws xob zam tsis dhau qhov kub thiab txias thaum lub sijhawm ua haujlwm. Yog li ntawd, cov khoom siv hluav taws xob flameproof yuav tsis yog qhov muaj peev xwm ntawm qhov hluav taws kub.
Vim li cas thiaj muaj kev tawg?
Kev tawg yog qhov hloov pauv tam sim ntawd ntawm ib lub xeev mus rau lwm lub xeev los ntawm kev hloov pauv ntawm lub cev lossis tshuaj lom neeg, thiab tso tawm lub zog loj. Lub zog tso tawm ntawm qhov nrawm nrawm yuav ua rau cov khoom nyob ib puag ncig muaj kev cuam tshuam hnyav thiab kev puas tsuaj. Peb cov xwm txheej yuav tsum tau ua tiav rau qhov tawg: cov khoom tawg, oxygen, thiab qhov hluav taws kub. Objectively, ntau qhov chaw ua haujlwm tau ntsib cov xwm txheej tawg. Thaum qhov sib xyaw ua ke ntawm cov khoom tawg thiab cov pa oxygen nyob rau hauv qhov kev txwv tawg, yog tias muaj qhov tawg, qhov tawg yuav tshwm sim.
Kev tiv thaiv lub cim ntawm kev tawg yuav tsum raug txiav txim siab los ntawm peb qhov tsim nyog saum toj no, thiab txwv ib qho ntawm cov xwm txheej tsim nyog txwv tsis pub muaj kev tawg. Cov khoom siv hluav taws xob kuj yog qhov muaj peev xwm ntawm qhov hluav taws kub. Thaum lub tshuab ua haujlwm, nws yuav ua rau qhov kub thiab txias ntawm qhov chaw nce, electrostatic tawm los yog hluav taws xob hluav taws xob tshwm sim los ntawm tam sim no tam sim no. Los ntawm qhov tsim ntawm qhov pom, cov khoom siv hluav taws xob flameproof tuaj yeem kaw qhov sib tov sib xyaw ua ke hauv lub casing, uas yog tshwj xeeb tshaj yog muaj zog, tuaj yeem tiv taus qhov tawg siab ntawm cov khoom tawg hauv qhov sib xyaw, thiab tiv thaiv kev tawg ntawm cov khoom tawg tawm sab nraum lub casing. Yog li ntawd, cov khoom siv hluav taws xob flameproof tuaj yeem tiv thaiv los ntawm kev ua qhov muaj peev xwm ntawm qhov hluav taws kub.
Lub tshuab hluav taws xob tawg-pov thawj tsim los ntawm peb lub tuam txhab yog tsim los tiv thaiv cov hluav taws xob sab hauv lossis cov neeg nqa khoom tawg los ntawm kev tiv thaiv sab nraud los ntawm qhov tawg-pov thawj ntawm lub plhaub. Lub ntsej muag dav (12.5mm-25mm) kom paub meej qhov no. Tsis tas li ntawd, qhov sib koom ua ke ntawm txhua qhov sib txuas, xws li cov xov xov tig, xov raug, xoom taw tes, ntsia hlau, nruab nrab ntawm lub qhov rais ntiv tes thiab lub plhaub, lub cev muaj zog thiab qhov chaw nres nkoj, qhov sib txawv ntawm cov khoom siv thiab cov khoom siv, thiab cov chaw nres nkoj xaim, thiab lwm yam, yog tag nrho raws li lub sijhawm tsim raws li qhov yuav tsum tau ua kom tawg, thiaj li ua kom ntseeg tau tias qhov kub siab tsim los ntawm kev tawg sab hauv yuav tsis ua rau lub actuator puas.
Kev faib tawm ntawm cov khoom siv hluav taws xob tawg
Cov khoom siv hluav taws xob muaj kev nyab xeeb hauv tsev: Cov khoom siv hluav taws xob uas nws txhua qhov hluav taws xob muaj kev nyab xeeb hauv hluav taws xob yog hu ua cov khoom siv hluav taws xob muaj kev nyab xeeb intrinsically.
