CovBEd Seriesyog ntau hom kev lag luam-qib tawg- tiv thaiv electro- hydraulic thrusters tsim kom muaj kev nyab xeeb, hnyav- lub luag haujlwm ua haujlwm nyob rau hauv qhov chaw muaj phom sij tawg -xws li underground thee mines, petrochemical plant, oil refineries, and gas storage chaw. Ua nyob rau hauv lub hauv paus ntawm tus qauv ED Series thrusters, nws integrates aflameproof enclosure, tawg-cov khoom muaj kev nyab xeeb, thiab cov tshuab hydraulic muaj zog kom tshem tawm cov teeb meem hluav taws xob thaum xa tawm cov zis siab. Tsim los rau kev tsav tsheb hnyav - lub luag haujlwm nres (xws li YWZ5 series nruas nres) thiab clutches nyob rau hauv siab - kev pheej hmoo machinery, BEd Series npog thrust quab yuam los ntawm 500–12,500 N thiab stroke ntev ntawm 50–200 mm, ua rau nws haum rau nruab nrab {{10} lub luag haujlwm (av-2{110}) tawg tsam. Hauv qab no yog cov ncauj lus kom ntxaws txog nws cov yam ntxwv tseem ceeb, txoj hauv kev ua haujlwm, cov yam ntxwv tseem ceeb, cov ntawv thov raug, thiab cov kev qhia tshwj xeeb:
1. Series Overview & Core Function
BEd Series (B=Explosion-Protected, E=Electric, d=Flameproof Design) yog cais raws li ib tugkev nyab xeeb- lub zog tseem ceebrau qhov chaw tawg, txuas hluav taws xob tswj cov tshuab thiab cov tshuab nres / clutch mechanisms. Nws cov haujlwm tseem ceeb ua haujlwm nrog siab -kev pheej hmoo kev lag luam xav tau:
Hnyav -Lub luag haujlwm nres nres: Ua kom muaj kev tawm dag zog kom tso tawm lub caij nplooj ntoo hlav- koom nrog cov brakes hnyav (xws li mine hoist brakes, chaw nres nkoj crane brakes) thaum lub sijhawm ua haujlwm, thiab nres nres kom muaj kev kub ntxhov ceev.
Clutch tswj: Sib koom / disengaging clutches rau lub hwj chim kis tau tus mob nyob rau hauv machinery xws li mining conveyors los yog petrochemical twj tso kua mis, kom ntseeg tau du torque hloov tsis muaj ignition txaus ntshai.
Ua tsis tiav -Kev Ua Haujlwm Zoo: Tam sim ntawd nres qhov tso zis tawm thaum lub zog poob lossis lub cev tsis ua haujlwm, tso cai rau cov brakes kaw cov tshuab thiab tiv thaiv kev sib tsoo hauv huab cua tawg.
Nrog rau kev ua raws li cov qauv kev nyab xeeb thoob ntiaj teb tawg thiab ua tau zoo nrog hnyav- lub luag haujlwm kev lag luam, cov koob tau ua kom zoo rau kev ua haujlwm tsis tu ncua lossis tsis sib xws hauv hnyav, siab - teeb meem pheej hmoo.
2. Txoj Cai Ua Haujlwm
BEd Series ua haujlwm ntawm akaw electro- hydraulic hloov txoj cai, zoo ib yam li tus qauv ED Series tab sis nrog kev txhim kho tawg tau zoo - pov thawj ntsuas kom muaj cov hluav taws xob sab hauv lossis cua sov. Nws lub voj voog ua haujlwm suav nrog peb lub xeev tseem ceeb:
2.1 1. Thrust Generation (Brake Release/Clutch Engagement)
Thaum qhib ua haujlwm, qhov tawg- pov thawj hluav taws xob lub cev muaj zog (nyob rau hauv ib lub qhov thaiv hluav taws xob) tsav lub twj tso kua mis / lub twj tso kua mis. Lub twj tso kua mis rub cov roj hydraulic los ntawm lub ntim ntim hauv ntim thiab nias nws (8-16 MPa, qauv- nyob ntawm).
Cov roj siab ntws mus rau hauv ib qho - ua haujlwm hydraulic lub tog raj kheej, thawb lub piston thiab chrome-plated tso zis pas nrig sab nraud. Qhov no ua rau muaj kev tawm dag zog (500–12,500 N) txhawm rau ua kom lub hom phiaj nres / clutch- kov yeej lub caij nplooj ntoo hlav kom tso cov brakes lossis koom nrog clutches.
2.2 2. Thrust Retention (Sustained Operation)
Thaum cov zis tawm mus txog qhov siab tshaj plaws stroke (50-200 mm), lub siab nyem valve diverts cov roj ntau dhau rov qab mus rau lub reservoir. Qhov no tuav ruaj khov lub tog raj kheej siab, ua kom tus nres tso tawm (los yog clutch koom nrog) yam tsis muaj overloading lub cev muaj zog- tseem ceeb rau kev nruam- lub luag hauj lwm machinery xws li 24/7 mine conveyors.
2.3 3. Thrust Cessation (Emergency/Reset)
Thaum tsis muaj hluav taws xob, qhov dej xau, lossis kev kaw thaum muaj xwm txheej ceev, lub cev muaj zog thiab lub twj tso kua mis nres tam sim ntawd. Hydraulic siab dissipates, thiab tus nres rov qab springs (los yog clutch lub reset quab yuam) thawb cov zis pas nrig rov qab. Roj ntws rov qab mus rau hauv lub reservoir, tso cai rau tus nres los koom (los yog clutch kom disengage) thiab ruaj ntseg lub tshuab.
Cov ntaub thaiv flameproof muaj qhov muaj peev xwm sab hauv los yog kub dhau, tiv thaiv kev sib tsoo ntawm cov pa hluav taws xob sab nraud / plua plav.
