Txheej txheem cej luam
Multi-tig mine tawg-pov thawj valve hluav taws xob ntaus ntawv, tseem hu ua ZB valve hluav taws xob ntaus ntawv, yog tshwj xeeb tsim thiab tsim rau cov xwm txheej ntawm kev siv hauv cov mines. ZB hom denso yog tsim rau cov li qub nrog cov lus tsa suab ntawm lub phaj valve, xws li rooj vag li qub, dej faib li qub, lub rooj vag 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 valve phaj, xws li npauj npaim li qub, dampers, thiab lwm yam. ZB hom valve hluav taws xob ntaus ntawv (tom qab no xa mus rau raws li cov khoom siv hluav taws xob) yuav tsum tau sib xyaw nrog cov khoom tshwj xeeb KXBC mining flameproof valve hluav taws xob tswj lub thawv ua ntej nws tuaj yeem siv tau; KXBC tswj lub thawv tuaj yeem txuas nrog DCS system kom paub txog kev tswj tsis siv neeg. Kev ua haujlwm ntawm cov khoom siv 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.
Qauv
Qauv
ZB hom hluav taws xob ntaus ntawv 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:
Kev 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 Tswj mechanism:
Cov qauv yog qhia nyob rau hauv Fig.Thaum lub tso zis ncej yog raug rau ib tug tej yam torque, tus cab ua axial displacement nyob rau hauv tas li ntawd mus rotation, tsav lub bellcrank, uas tsav lub bracket los ntawm lub bumper los tsim angular displacement; Thaum lub torque ntawm cov zis ncej nce mus rau lub teeb torque, Tom qab ntawd qhov kev hloov pauv 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 thawv txo 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 kho raws li qhov qhib thiab kaw txoj haujlwm ntawm lub valve, thaum lub tshuab hluav taws xob tswj tau tig mus rau qhov hloov kho ua ntej (tus naj npawb ntawm cov lem) nrog rau 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, kom paub txog kev tswj cov hlab ntsha tawg (ntau zaus ntawm kev hloov pauv) ntawm cov khoom siv hluav taws xob.
Qhib qhia mechanism:
Cov qauv yog qhia nyob rau 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-electric switching:
Nws yog ib tug semi-automatic hloov, koj yuav tsum rub tus kov hloov thaum phau ntawv, thiab nws yuav khiav tau txais thaum lub xeev phau ntawv hloov mus rau hluav taws xob. Nws cov qauv yog qhia nyob rau hauv daim duab 7. Nws yog tsim los ntawm tes, hloov qhov chaw, upright rods, clutches, nias cov ntaub ntawv, thiab lwm yam. Thaum handwheel ua hauj lwm yuav tsum tau, 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, 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 tes log tib lub sij hawm, cia li realizing phau ntawv ua hauj lwm. hloov mus rau lub xeev hluav taws xob.
