High Quality BEd Series Explosion-Protected Electro-Hydraulic Thrusters

 

 

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 dua - 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 npog flameproof muaj cov khoom muaj peev xwm sab hauv los yog kub dhau, tiv thaiv kev sib tsoo ntawm cov pa hluav taws xob sab nraud / plua plav.

3. Core Structure & Explosion -Cov khoom tiv thaiv

BEd Series nta qhov hnyav, tawg-kev nyab xeeb tsim nrog tsib qhov tseem ceeb subsystems, txhua tus ua raws li nruj kev phom sij- cov qauv hauv cheeb tsam:

3.1 1. Flameproof Electric Tsav (Power Input)

Peb -theem AC induction lub cev muaj zog nrogExd I Mb/Exd IIB T4 Ga explosion-cov ntawv pov thawj(ua raws li GB 3836-2010 thiab ATEX / IECEx cov qauv). Nws yog haum rau:

Underground coal mines: Exd I Mb rau methane-ib puag ncig nplua nuj.

Saum - hauv av kev lag luam: Exd IIB T4 Ga for Class IIB explosive gas zones (eg, petrochemicals, gas storage) with temperature class T4 (Less than or equal to 135 degree).

Lub cev muaj zog lub cev muaj zog ntawm 0.37–7.5 kW, nrog dual - cov kev xaiv hluav taws xob (380V / 660V, 660V / 1140V AC, 50Hz) kom phim cov tshuab hluav taws xob mine / petrochemical. Rwb thaiv tsev chav kawm yogChav F(kub tsis kam mus txog 155 degree) rau siab -kub kam rau ua.

3.2 2. Sealed Hydraulic Fais Fab Unit (Lub zog hloov pauv)

Explosion-Safe Pump: Lub twj tso kua mis suab nrov qis (tsawg dua lossis sib npaug li 12 MPa) lossis lub twj tso kua mis vane (rau 12–16 MPa) uas tsis yog- cov khoom siv hluav taws xob (piv txwv li, tooj liab- alloy iav) kom tsis txhob muaj kev sib txhuam - cuam tshuam cov pa taws. Nws yog tag nrho nyob rau hauv lub flameproof vaj tse.

Airtight Reservoir: Ib lub pas dej steel (muaj peev xwm: 0.5-5 L) nrog lub hau kaw thiab flameproof breather valve. Nws tiv thaiv cov roj to thiab thaiv cov roj hluav taws xob sab nraud los ntawm kev nkag mus rau hauv hydraulic system.

Siab Safety Valves: Lub valve nyem (kom txwv max siab) thiab kos valve (kom tiv thaiv cov roj rov qab) - ob qho tib si nrog tawg- cov ntaub ntawv pov thawj los tuav lub kaw lus kev ncaj ncees.

3.3 3. Hnyav-Lub Hwj Huam Hydraulic Lub tog raj kheej (Force Output)

Ib qho - ua lub tog raj kheej nrog anyuaj chrome-plated tso zis pas nrig(inch: 20-60 mm) rau corrosion kuj thiab hnav txo. Lub tog raj kheej bore (40-125 mm) thiab stroke (50-200 mm) yog optimized rau hnyav thrust xav tau.

Siab -Tseem Foob: Fluoropolymer (FKM) cov ntsaws ruaj ruaj (tus qauv) tiv thaiv cov roj to thiab tiv taus kub ntawm -20℃txog 120 degree, haum rau kub petrochemical lossis kuv qhov chaw ib puag ncig.

3.4 4. Flameproof Enclosure (Safety Core)

Cast Steel / Aluminium Tsev: Ib lub qhov rooj ruaj khov nrog cov pob qij txha uas tsis muaj nplaim taws (qhov sib txawv tsawg dua lossis sib npaug li 0.15 hli) uas txias thiab muaj cov khoom tawg sab hauv, tiv thaiv cov nplaim taws tawm mus rau sab nraud cov cua tawg.

Kev tiv thaiv IP65: Cov ntaub thaiv npog yog plua plav- nruj thiab dej- dav hlau tiv taus, tiv thaiv cov khoom sab hauv los ntawm kuv cov plua plav, petrochemical spills, lossis los nag- tseem ceeb rau kev siv sab nraum zoov / hauv av.

Kev tawg-Cov pov thawj Cable Glands: Cov ntaub ntawv kaw cov kab nkag (tshaj nrog armored cables) tiv thaiv cov roj nkag thiab xyuas kom tsis muaj qhov hluav taws xob khiav tawm ntawm cov chaw nres nkoj.

3.5 5. Kev Txhim Kho & Hloov Cov Cheeb Tsam

Universal Mounting: Lub hauv paus rotatable flange (90℃hloov) thiab 360℃swiveling qws taub hau tso cai ntsug, kab rov tav, lossis inclined installation, yoog rau qhov chaw kaw hauv kuv lub hoists lossis petrochemical twj.

Anti-Corrosion Txheej: Sab nrauv yog coated nrog epoxy resin (100μm thickness) los tiv thaiv kuv cov dej, tshuaj vapors, thiab ntsev tsuag (rau offshore petrochemical chaw).

4. Cov yam ntxwv tseem ceeb & qhov zoo

BEd Series sawv tawm rau nws qhov kev tiv thaiv tawg, hnyav- kev ua haujlwm, thiab ua raws, nrog cov txiaj ntsig tseem ceeb rau kev lag luam muaj kev pheej hmoo siab -:

4.1 1. Ntau-Txoj Kev Pov Hwm Kev Nyab Xeeb

Ua raws li cov qauv thoob ntiaj teb (GB 3836-2010, ATEX 2014/34/EU, IECEx) thiab npog ob qho tib si underground coal mines (Exd I Mb) thiab saum toj no -chav kawm IIB explosive zones (Exd IIB T4 Ga), ua kom muaj kev sib tw thoob plaws hauv high-risk.

4.2 2. Hnyav-Lub luag haujlwm Thrust & Durability

Muab 500–12,500 N ntawm thrust-3-5 zaug siab dua qhov tawg me me-cov pov thawj thrusters (xws li BYT1 Series)-ua rau nws haum rau hnyav nres / clutches hauv kuv hoists, loj conveyors, lossis chaw nres nkoj cranes.

4.3 3. Sealed & Tsawg-Kev Tsim Kho Kho

Lub kaw lus hydraulic tag nrho thiab cov vaj tsev flameproof tiv thaiv plua plav, dej, lossis roj ingress, txo cov khoom hnav thiab tu ntau zaus.

Class F rwb thaiv tsev thiab FKM cov ntsaws ruaj ruaj ua kom lub neej ua haujlwm siab dua lossis sib npaug li 10,000 teev ua haujlwm nyob rau hauv kev ua haujlwm tsis tu ncua- tseem ceeb rau cov chaw hauv thaj chaw deb nrog cov kev saib xyuas tsawg.

4.4 4. Teb ceev ceev & Zog Efficiency

Thrust build- lub sij hawm nce (pib mus rau tag nrho stroke) tsawg dua los yog sib npaug li 0.8 vib nas this, ua kom ceev nres nres rau cov tshuab nrog lub sij hawm luv luv (piv txwv li, kuv hoists).

Lub siab nyem valve txiav lub cev muaj zog load tom qab ncav cuag tag nrho cov hlab ntsha tawg, txo hwj chim noj los ntawm 30-50% piv rau tas li -load systems.

4.5 5. Compatibility nrog Legacy Systems

Standardized mounting flanges thiab output rod dimensions match heavy-duty brakes (piv txwv li, YWZ5, YWZ9 series) thiab clutches, ua rau nws hloov ncaj qha rau tsis yog - tawg- pov thawj ED Series thrusters nyob rau hauv retrofitting siab - kev pheej hmoo machinery.

5. Cov ntawv thov ib txwm

BEd Series yog lub hom phiaj- tsim rau nruab nrab- rau- ua haujlwm hnyav hauv qhov chaw tawg:

Underground Coal Mines: Tsav tsheb nres rau mine hoists (ore lifting), siv conveyors (coal thauj), thiab shearers; tswj clutches rau underground crushers.

Petrochemical / Roj Refining: Actuating thaum muaj xwm ceev nres rau pipeline twj, tank ua liaj ua teb conveyors, thiab roj compressors; koom nrog clutches rau distillation ntauwd agitators.

Gas Cia & LNG Chaw: Kev khiav hauj lwm nres rau cov tsheb thauj mus los cryogenic tank thiab roj loading / unloading cranes hauv Class IIB explosive zones.

Mining & Metallurgy: Tswj brakes rau cov ntxhia ua conveyors thiab hoists nyob rau hauv sulfur ore los yog hlau mines nrog flammable plua plav / roj.
