DZW Electric Valve Actuator
Qhov ntau tig tawg-pov thawj hluav taws xob valve actuator, tseem hu ua ZB hluav taws xob valve actuator, yog tsim tshwj xeeb thiab tsim rau cov kev siv hauv cov mines. ZB hom yog tsim rau cov li qub nrog cov lus tsa suab ntawm lub phaj valve, xws li lub rooj vag li qub, lub ntiaj teb li qub, lub qhov rooj dej, thiab lwm yam .; Tom qab ntxiv ob-theem deceleration cab iav lub thawv, nws kuj siv tau rau li qub nrog 90-degree rotation ntawm lub valve phaj, xws li npauj npaim li qub, dampers, thiab lwm yam. ZB hom hluav taws xob valve actuator (tom qab no xa mus rau raws li lub tshuab hluav taws xob hluav taws xob) yuav tsum tau sib xyaw nrog cov khoom siv tshwj xeeb flameproof hluav taws xob valve actuator tswj lub thawv ua ntej nws tuaj yeem siv tau; lub thawv tswj kuj tuaj yeem txuas nrog DCS system kom paub txog kev tswj tsis siv neeg. Kev ua haujlwm ntawm lub tshuab hluav taws xob ua tau raws li lub tuam txhab tus qauv Q/3204CN001-2011 "Technical Conditions for Electric Devices of Mine Isolation Valves", GB3836.1-2010 "Explosive Atmosphere Part 1: Requirements for Equipment", GB3836. Lub cim tawg-pov thawj yog Exd I Mb.

txheeb ze humidity:<95% (at 25C)
Kev tiv thaiv hom, hom sab nraum zoov yog siv nyob rau hauv qhov chaw uas tsis muaj hluav taws kub, tawg thiab tsis-corrosive media. Cov khoom pov thawj tawg muaj xws li dI thiab dIBT4. dI yog qhov tsim nyog rau kev ua haujlwm tsis yog khawb hauv cov mines thee, thiab dIBT4 yog siv hauv cov chaw tsim khoom, thiab tsim nyog rau cov khoom tawg tawg uas nws ib puag ncig yog Pawg IIA thiab IIB T1 ~ T4. Kev tiv thaiv qib: IP55 (kev txiav txim tshwj xeeb IP65, IP67)
Lub sijhawm ua haujlwm: luv luv 10 feeb (kev txiav txim tshwj xeeb 30 feeb).
Cov qauv
Cov qauv
ZB hom hluav taws xob actuator yog tsim los ntawm lub cev muaj zog, deceleration mechanism, torque tswj mechanism, stroke tswj mechanism, qhib qhia mechanism, tes-electric switching mechanism, tes log thiab hluav taws xob qhov chaw. Nws txoj cai kis tau tus mob yog qhia nyob rau hauv daim duab
Lub cev muaj zog: tawg-pov thawj peb-theem asynchronous lub cev muaj zog rau hluav taws xob valve actuator nrog MA daim ntawv pov thawj.
Kev txo qis mechanism: Nws muaj ib khub ntawm spur zog thiab ib tug cab iav khub ntawm ob-theem kis tau tus mob; lub zog ntawm lub cev muaj zog yog xa mus rau cov zis ncej los ntawm kev txo cov mechanism
5.3 Control mechanism: Cov qauv yog qhia nyob rau hauv daim duab. Thaum lub tso zis ncej yog raug rau ib tug tej yam torque, tus cab ua axial displacement ntxiv rau kev sib hloov, tsav lub bellcrank, uas tsav lub bracket los ntawm lub bumper los tsim angular hloov chaw; Thaum lub torque ntawm cov zis ncej nce mus rau lub teeb torque, Tom qab ntawd qhov kev hloov chaw tsim los ntawm lub bracket ua rau lub zog hloov pauv, yog li txiav tawm lub zog ntawm lub cev muaj zog thiab nres lub cev muaj zog. Nyob rau hauv txoj kev no, kev tswj cov zis torque ntawm lub tshuab hluav taws xob yog pom tau, thiab lub hom phiaj ntawm kev tiv thaiv hluav taws xob valve tau tiav.
Kev tswj xyuas mechanism:
Nws siv lub hauv paus ntsiab lus ntawm tus lej lej, tseem hu ua txee, nrog kev tswj xyuas siab. Cov qauv yog qhia nyob rau hauv daim duab hauv qab no. Nws txoj hauv kev ua haujlwm yog: ib khub loj thiab me me bevel iav nyob rau hauv lub gearbox tsav lub nruab nrab kis tau tus mob pinion, thiab ces tsav lub stroke tswj mechanism ua hauj lwm. Yog tias lub tshuab hluav taws xob tswj tau raug hloov kho raws li qhov qhib thiab kaw txoj haujlwm ntawm lub valve, thaum lub tshuab hluav taws xob tswj tau tig mus rau qhov kev hloov kho ua ntej (tus naj npawb ntawm cov lem) nrog cov zis ncej, lub cam yuav tig mus rau qhov hloov pauv, yuam lub stroke hloov mus ua thiab txiav tawm lub cev muaj zog. Fais fab mov, lub cev muaj zog nres, thiaj li paub txog kev tswj cov hlab ntsha tawg (ntau zaus ntawm kev hloov pauv) ntawm cov hluav taws xob actuator.
Qhib qhov taw qhia mechanism: Cov qauv qhia hauv daim duab hauv qab no. Lub input iav yog tsav los ntawm chav tsev iav ntawm lub txee. Tom qab deceleration, qhov taw qhia phaj tig ib txhij nrog lub valve qhib thiab kaw txheej txheem los qhia tus nqi kaw ntawm lub valve. Lub potentiometer ncej thiab qhov taw qhia phaj tig synchronously rau cov chaw taws teeb qhib qhov taw qhia. Tus naj npawb ntawm cov kiv puag ncig tuaj yeem hloov pauv los ntawm kev txav tus naj npawb ntawm cov kiv cua hloov kho. Muaj ib lub micro hloov thiab lub cam nyob rau hauv qhov qhib qhia mechanism. Thaum lub tshuab hluav taws xob khiav, lub cam tig ib ntus ua rau lub micro hloov ua haujlwm, thiab nws qhov zaus yog ib qho los yog ib qho kev hloov pauv ntawm cov zis tawm, uas tuaj yeem siv rau flashing signals, thiab lwm yam.
Tes-hluav taws xob hloov pauv: Nws yog qhov hloov pauv ib nrab tsis siv neeg, koj yuav tsum rub tus kov hloov thaum phau ntawv, thiab nws yuav khiav tau thaum lub xeev phau ntawv hloov mus rau hluav taws xob. Nws cov qauv yog pom nyob rau hauv daim duab 7. Nws yog tsim los ntawm tes, switching qhov chaw, upright rods, clutches, nias cov ntaub ntawv, thiab lwm yam. Thaum handwheel ua hauj lwm yuav tsum, thawb tus kov mus rau phau ntawv qhia, thiab lub switching piece yuav tsa lub clutch thiab compression caij nplooj ntoos hlav. Thaum tus kov raug thawb mus rau ib qho chaw, lub clutch yuav tawm ntawm lub log log thiab koom nrog lub tes log. Nyob rau tib lub sijhawm, tus pas nrig upright sawv ntsug ntawm lub ntsej muag kawg ntawm lub log cab nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoos hlav, txhawb lub clutch los ntawm kev poob. Tom qab kev hloov pauv tiav lawm, tus kov tuaj yeem tso tawm thiab lub log tes tuaj yeem siv rau kev ua haujlwm. Thaum lub tshuab hluav taws xob yuav tsum tau ua haujlwm, lub cev muaj zog yuav tsav lub log cab kom tig, thiab tus pas nrig ncaj uas txhawb nqa ntawm lub ntsej muag kawg ntawm lub log log yuav poob. Nyob rau hauv qhov kev txiav txim ntawm lub siab lub caij nplooj ntoos hlav, lub clutch yuav sai sai txav mus rau cov kev taw qhia ntawm lub log log, mesh nrog lub log log, thiab disengage los ntawm txhais tes log tib lub sij hawm, cia li realizing phau ntawv ua hauj lwm. hloov mus rau lub xeev hluav taws xob.
