CovSBD80-B-1250 × 30IRLyog ib qho hnyav- lub luag haujlwm muaj kev nyab xeeb kev nyab xeeb ua haujlwm rau qhov tseem ceeb nres, thauj khoom- tuav, thiab kev tiv thaiv thaum muaj xwm txheej ceev ntawm nruab nrab- mus rau -rotating machinery loj-xws li mine hoists, hnyav- lub luag haujlwm conveyors, chaw nres nkoj gantry cranes, thiab cov khoom siv hlau. Classified ua atsis ua haujlwm- nyab xeeb, caij nplooj ntoos hlav- koom nrog, hydraulic- tso tawm nres, nws ua ke nrog kev ua haujlwm siab braking, kev tsim qauv zoo, thiab cov lus teb thaum muaj xwm ceev txhim khu kev qha los tiv thaiv cov tshuab khiav hauv siab - kev pheej hmoo ua haujlwm. Tus qauv tsim (SBD80-B-1250 × 30IRL) qhia txog nws cov ntsiab lus tseem ceeb: "SBD" rau Kev Nyab Xeeb Nres Tsim, "80" rau nominal braking torque (80 kN·m), "B" rau Enhanced Series (zoo rau qhov hnyav 50 mm), "12" disc rau disc thickness (30 mm), "I" rau Integrated Actuation, thiab "RL" rau Txoj Cai-Sab laug dual-mounting compatibility. Siv dav hauv mining, ports, thiab steel ntau lawm, nws ua kom muaj kev nyab xeeb ntawm kev ua haujlwm raws li kev thauj khoom ntawm 200-1000 tons thiab kev ua haujlwm hnyav (plua plav, kev vibration, kub kub). Hauv qab no yog cov ncauj lus kom ntxaws txog nws cov yam ntxwv tseem ceeb, lub hauv paus ntsiab lus ua haujlwm, cov yam ntxwv tseem ceeb, cov ntawv thov raug, thiab cov kev qhia tshwj xeeb:
1. Qauv txhais lus & Core Function
SBD80-B-1250 × 30IRL tus qauv code ncaj qha cuam tshuam nws cov qauv tsim thiab kev taw qhia ua haujlwm, ua kom yooj yim rau cov khoom siv ceev sib xws:
| Qauv Segment | Lub ntsiab lus |
|---|---|
| SBD | Safety Brake Design (ua tsis tau tejyam -kev nyab xeeb, caij nplooj ntoos hlav- hom) |
| 80 | Nominal braking torque: 80 kN·m (tsim rau nruab nrab - rau - hnyav loads) |
| B | Txhim kho Series (cov qauv siv zog, tiv thaiv-corrosion, hnyav- ib puag ncig yoog) |
| 1250 | Tau tshaj nres disc txoj kab uas hla: 1250 mm (sib npaug torque thiab compact layout) |
| 30 | Tau tshaj nres disc thickness: 30 hli (siab-lub zog, hnav-resistant) |
| I | Integrated Actuation (hydraulic lub tog raj kheej thiab caliper integrated tsim) |
| RL | Mounting orientation: Txoj cai-Sab laug dual- tau sib xws (kev txhim kho yooj yim) |
Nws cov haujlwm tseem ceeb yog tsim los rau kev nyab xeeb- xwm txheej tseem ceeb:
Kev Ceev Xwm Ceev: Ceev ceev decelerating los yog nres machinery nyob rau hauv tsawg dua los yog sib npaug zos rau 0.4 vib nas this nyob rau hauv rated load (xws li, hoist overspeed, conveyor blockage).
Static Load Holding: Kev ruaj ntseg cov khoom hnyav (piv txwv li, nqa ore, ntim) nyob rau hauv qhov chaw thaum lub sij hawm poob, txij nkawm, los yog hluav taws xob tawm - tiv thaiv kev sib tsoo.
Overload & Fault Protection: Tsis siv neeg lub zog poob, hydraulic system to, los yog overspeed (kuaj los ntawm sensors), ua raws li qhov kawg kev nyab xeeb thaiv kom tsis txhob muaj cov khoom puas tsuaj los yog xwm txheej.
2. Txoj Cai Ua Haujlwm
SBD80-B-1250 × 30IRL ua haujlwm ntawm aua tsis tiav- txoj hauv kev nyab xeeb (caij nplooj ntoos hlav- koom nrog, hydraulic- tso tawm), xyuas kom muaj peev xwm braking txawm tias qhov kev ua haujlwm tsis ua haujlwm. Nws lub voj voog ua haujlwm suav nrog peb lub xeev tseem ceeb:
2.1 1. Kev Sib Koom Tes Nres (Safety State)
Thaum lub tshuab ua haujlwm ruaj khov, thaum muaj xwm txheej ceev, lossis lub zog tawm, sab hauv siab - nro disc springs (60Si2MnA alloy steel) nthuav dav.
Cov springs thawb cov kev sib xyaw ua ke dual -sided calipers mus rau lub rotating brake disc, clamping lub disc ntawm siab -kev ua tau zoo ntawm kev sib txhuam.
Kev sib txhuam ntawm cov ntaub qhwv thiab disc ua rau 80 kN·m ntawm kev ruaj ntseg braking torque, nres lub disc (thiab txuas lub tshuab ncej) lossis tuav nws ruaj khov.
2.2 2. Nres Tso Tawm (Lub Xeev Ua Haujlwm)
Thaum lub tshuab yuav tsum tau khiav, lub kaw lus tswj muab hydraulic siab (10-18 MPa) rau cov hydraulic thooj voos kheej kheej ntawm lub calipers.
Hydraulic quab yuam overcomes lub disc caij nplooj ntoos hlav nro, rub lub calipers deb ntawm lub nres disc thiab tsim ib tug 0.3-0.6 hli clearance.
Lub brake disc tig ywj siab nrog lub tshuab ua haujlwm, ua kom muaj kev ua haujlwm zoo (xws li hoisting, conveying).
2.3 3. Teb thaum muaj xwm ceev (Fault State)
Nyob rau hauv cov ntaub ntawv ntawm lub hwj chim poob, hydraulic to, los yog txawv txav ceev, lub actuation quab yuam dissipates instantly.
Disc springs nthuav dav li tsawg dua lossis sib npaug li 0.25 vib nas this, tsav lub calipers kom clamp lub disc -tsim lub siab tshaj plaws braking torque kom nres lub tshuab tam sim ntawd.
3. Core Structure & Cov Khoom Tseem Ceeb
SBD80-B-1250 × 30IRL nta lub zog, txhim khu kev qha nrog plaub qhov tseem ceeb subsystems, optimized rau durability thiab hnyav-ib puag ncig adaptability:
3.1 1. Integrated Caliper & Actuation Unit (Core Assembly)
Dual -Sided Calipers: Reinforced cam khwb cia hlau (QT600-3) calipers nrog integrated hydraulic thooj voos kheej kheej (2-4 lub tog raj kheej ib lub nres), txo cov kav dej sab nraud thiab kev pheej hmoo ntawm cov dej xau. Cov qauv txhim kho tiv thaiv kev co thiab cuam tshuam hauv kev siv mining / conveyor.
High -Kev Ua Haujlwm Sib Nqus Cov Ntaub Ntawv: Ceramic-cov khoom siv hlau sib xyaw nrog kev sib txhuam coefficient (μ Ntau dua lossis sib npaug li 0.45) thiab ua haujlwm kub txog 600℃. Pads yog bolted rau kev hloov ceev (tsawg dua los yog sib npaug li 15 feeb ib txheej) thiab muaj kev tiv thaiv -squeal tsim.
Automatic Wear Adjuster: Tus neeg kho tshuab kho qhov tseeb uas them nyiaj rau lub ncoo hnav (txog 10 hli), tswj kom tsis txhob muaj kev sib cais tsis tu ncua tsis muaj phau ntawv calibration - tseem ceeb rau kev ua haujlwm 24/7.
3.2 2. Disc Spring Mechanism (Safety Core)
Disc Spring Stack: Siab -lub zog 60Si2MnA disc springs teem nyob rau hauv parallel kom ruaj khov clamping quab yuam (40-60 kN tag nrho). Cov pawg yog coated nrog cov khoom siv los tiv thaiv -corrosion kom ntev kev pab cuam lub neej nyob rau hauv qhov chaw ntub dej.
Caij nplooj ntoos hlav Guide Tsho: Ib qho hnav- lub tes tsho steel tiv taus uas ua kom lub caij nplooj ntoos hlav nthuav dav / sib cog lus, tsis txhob cuam tshuam thiab ua kom ntseeg tau tias muaj kev koom tes hauv cov plua plav.
3.3 3. Kev Nyab Xeeb & Kev Ntsuas Qhov Ntsuas (Control Core)
Limit Switches: Ob txoj haujlwm sensors (ib qho rau "tag nrho koom nrog," ib qho rau "tso tawm tag nrho") uas xa cov teeb liab mus rau lub tshuab PLC. Qhov no 实现 interlock tswj (tsuas yog lub tshuab pib thaum nres nres, nres yog nres tsis ua hauj lwm).
Hnav & Siab Sensors: Kev xaiv inductive hnav sensors (tseem ceeb ceeb toom thaum ncoo thickness Tsawg dua los yog sib npaug li 3 hli) thiab hydraulic siab sensors (saib qhov system siab, ua rau muaj kev kub ntxhov yog qhov txawv txav).
Phau Ntawv Qhia Thaum Muaj Xwm Ceev: Ib tug neeg kho tshuab phau ntawv tso tawm lever rau thaum muaj xwm ceev pib dua thaum lub hwj chim poob, xyuas kom meej kev saib xyuas yooj yim.
3.4 4. Mounting & Protection Cheebtsam (Durability Core)
Adjustable Mounting Brackets: Reinforced steel brackets nrog ± 10 hli kab rov tav / ntsug hloov kho, yooj yim sib dhos nrog lub nres disc thaum lub sijhawm teeb tsa thiab hloov kho rau cov tshuab kev co.
Environmental Protection Npog: IP66- ntsuas steel npog (kev tiv thaiv siab dua li cov qauv qauv) uas tiv thaiv cov khoom sab hauv los ntawm cov plua plav hnyav, dej raus dej (lub sijhawm luv-), thiab cov khoom siv cuam tshuam-tsim rau cov mines hauv av thiab cov chaw nres nkoj ntug hiav txwv.
Anti-Corrosion Txheej: Muab ob npaug rau- txheej epoxy resin txheej (100-120 μm) ntawm calipers thiab brackets, tiv thaiv kuv cov dej, ntsev tsuag, thiab cov tshuaj siv tshuaj.
