CovTWZ(B) Seriesyog ntau hom kev lag luam -qib ko taw- lub nruas nres tsim los rau kev tuav tswj lub teeb- mus rau - lub luag haujlwm nruab nrab ntawm lub tshuab ua haujlwm, suav nrog me me winches, cov khoom siv tsheb thauj khoom, rhiav cranes, thiab qis- tsheb muaj tsheb. Lub series muaj ob tug zoo sib xws variants:TWZ(basic mechanical actuation) thiabTWS (B)(txhim kho nrog kev pab cuam hydraulic), ob qho tib si ua ntej kev tswj xyuas tus neeg teb xov tooj, kev saib xyuas yooj yim, thiab txhim khu kev qha braking rau cov ntawv thov uas tsis siv neeg lub tshuab tsis tsim nyog lossis siv tsis tau. Nrog lub nruas diameters los ntawm 150-400mm thiab torque outputs los ntawm 80-1,500 N·m, series caters rau loads ntawm 0.5-10 tons, ua rau nws haum rau rhiav, warehouses, thiab lub teeb tsim chaw. Hauv qab no yog cov ncauj lus kom ntxaws txog lawv cov yam ntxwv tseem ceeb, cov qauv kev ua haujlwm, cov yam ntxwv tseem ceeb, cov ntawv thov raug, thiab cov kev qhia tshwj xeeb:
1. Series Overview & Core Function
The TWZ(B) Series (T=Foot, W =} Drum, Z=Basic, B=Hydraulic-}Assisted) yog engineered raumanual braking tswj, nrog rau ob qhov sib txawv hais txog qhov sib txawv ntawm qhov yuav tsum tau muaj zog:
TWS (Basic): Tsuas yog nyob ntawm kev sib txuas ntawm cov khoom siv sib txuas (pedal + levers) kom xa cov ko taw quab yuam rau cov khau nres. Qhov zoo tshaj plaws rau lub teeb- daim ntawv thov lub luag haujlwm (0.5-5 tons) qhov twg qis braking torque txaus.
TWZ(B) (Hydraulic{0}}Assisted): Kev sib koom ua ke ib lub tog raj kheej hydraulic me me kom ua kom lub zog pedal, txo cov neeg siv kev siv zog thaum nce lub zog. Haum rau nruab nrab- cov dej num ua haujlwm (3-10 tons) uas xav tau lub zog nres ntau dua.
Lawv cov haujlwm tseem ceeb sib koom suav nrog:
Tus neeg teb xov tooj -Controlled Stopping: Ua kom du, maj mam deceleration lossis nres thaum muaj xwm txheej ceev ntawm ko taw siab, qhov tseem ceeb rau kev tso cov khoom me me lossis taug kev nruj.
Static Load Holding: Kev ruaj ntseg machinery / loads thaum lub pedal yog xauv (ntawm ib tug neeg kho tshuab latch), tshem tawm qhov yuav tsum tau rau tus neeg teb xov tooj input input.
Backup Braking: Ua hauj lwm raws li ib tug txhim khu kev qha phau ntawv thaub qab rau automated systems, kom muaj kev ruaj ntseg nyob rau hauv lub hwj chim tsis ua hauj lwm los yog thawj nres faults.
2. Txoj Cai Ua Haujlwm
Ob qho kev hloov pauv ua haujlwm ntawm phau ntawv actuation tab sis sib txawv hauv kev sib kis, hloov mus rau qhov xav tau:
2.1 TWZ (Basic Mechanical Actuation)
Nres Tso Tawm: Thaum lub pedal tsis muaj kev nyuaj siab, rov qab springs retract lub nres khau, tsim ib tug 0.3-0.5mm qhov sib txawv ntawm nkawm khau thiab rotating nruas. Lub nruas (txuas mus rau lub tshuab ncej) tig tau ywj pheej.
Kev sib koom tes nres: Kev ntxhov siab ntawm lub pedal rub ib qho kev sib txuas ntawm cov neeg kho tshuab, uas thawb cov khau nres rau lub nruas. Braking torque yog ncaj qha proportional rau pedal quab yuam (30-80 N), ua kom yooj yim tab sis yuav tsum tau siv zog ntau dua rau cov neeg siv khoom hnyav dua.
Load Holding: Lub pedal latch xauv qhov kev sib txuas hauv "cov khau koom nrog" txoj hauj lwm, tuav lub zog kom tuav lub load statically.
2.2 TWZ(B) (Hydraulic-Assisted Actuation)
Nres Tso Tawm: Zoo ib yam li TWZ variant- rov qab caij nplooj ntoos hlav rov qab khau thaum lub pedal tsis ua haujlwm.
Kev sib koom tes nres: Kev ntxhov siab rau lub pedal thawj zaug ua rau lub twj tso kua mis hydraulic me me (ua ke rau hauv lub rooj sib txoos pedal). Lub twj tso kua mis tsim tawm qis - mus rau - nruab nrab siab (5-12 MPa), uas tsav lub tog raj kheej hydraulic rau ntawm tus nres. Lub tog raj kheej txhawb nqa lub zog los thawb cov khau tiv thaiv lub nruas, txo qhov xav tau pedal quab yuam los ntawm 40-60% piv rau TWZ yooj yim.
Load Holding: Dual -locking system (pedal latch + hydraulic check valve) tswj lub siab / lub tog raj kheej txoj hauj lwm, ua kom ruaj ntseg load tuav txawm tias lub pedal tawm me ntsis.
3. Core Structure & Cov Khoom Tseem Ceeb
Lub TWZ thiab TWZ(B) sib koom ib qho qauv, rugged tsim nrog variant - cov khoom tshwj xeeb rau kev sib kis:
3.1 Cov Cheebtsam sib koom
Ko taw Pedal & Txuas: Ib qho hnyav- lub luag haujlwm steel pedal nrog cov tsis muaj - cov roj hmab rub tawm, txuas nrog zinc- plated lever system rau corrosion resistance thiab durability.
Nruas Braking Assembly:
Nres Khau: Dual arcuate nkawm khau ua los ntawm QT400 ductile hlau (TWZ) los yog QT500 (TWZ(B)) rau lub zog.
Friction Linings: Resin-raws li cov ntaub ntawv sib xyaw (μ Ntau dua lossis sib npaug ntawm 0.40) nrog rau qhov kub thiab txias txog 300 degree, riveted rau khau kom hloov tau yooj yim.
Nruas Compatibility: Tsim los rau 150-400mm txoj kab uas hla drums (khoom siv: 45 # steel / cam khwb cia hlau), nrog adjustable brackets kom haum raws li qhov sib txawv variations.
Rov qab & Xauv Mechanism:
Rov qab Springs: Siab- nro steel springs uas pib dua lub pedal thiab khau thaum lub siab tso tawm.
Mechanical Pedal Latch: Lub pas nrig lossis tus pin uas tuav lub pedal nyob rau hauv txoj haujlwm nyuaj siab rau kev tuav zoo li qub.
3.2 TWZ(B)-Specific Hydraulic Components
Mini Hydraulic Pump & Lub tog raj kheej: Lub twj tso kua mis piston (pedal{0}}mounted) thiab ib zaug - ua haujlwm hydraulic lub tog raj kheej (brake-mounted) uas ua kom nrov zog yam tsis muaj hydraulics nyuaj.
Tsawg-Hloov Hoses & Kos Valve: Reinforced roj hmab hoses ( ntsuas rau 15 MPa) thiab ib daim tshev valve los tiv thaiv kev poob siab thaum tuav, kom ntseeg tau.
4. Cov yam ntxwv tseem ceeb & qhov zoo
TWZ(B) Series sawv tawm rau nws txoj kev yooj yim, yoog raws, thiab tus neeg siv- qauv tsim:
4.1 1. Dual -Variant Flexibility
Kev xaiv ntawm TWZ (mechanical) thiab TWZ(B) (hydraulic-pab) tso cai rau kev sib txuam ntawm lub nres kom thauj khoom xav tau- zam dhau- engineering (rau lub teeb ua haujlwm) lossis tus neeg teb xov tooj qaug zog (rau cov haujlwm nruab nrab).
4.2 2. Yooj yim & Tsawg-Kev tu
Tsis muaj cov khoom siv hluav taws xob nyuaj lossis siab - hydraulics siab (txawm tias TWZ(B)), txo cov ntsiab lus tsis ua haujlwm.
Kev sib txhuam hauv ob sab phlu tuaj yeem hloov tau tsawg dua lossis sib npaug li 20 feeb nrog cov cuab yeej yooj yim, thiab TWZ (B) hydraulic system yuav tsum tsuas yog qee lub sijhawm kuaj roj (mineral hydraulic roj).
4.3 3. Intuitive & Fatigue-Txo kev ua haujlwm
Lub TWZ(B) kev pabcuam hydraulic txiav pedal quab yuam mus rau 20-50 N, ua rau nws yooj yim rau kev siv txuas ntxiv (piv txwv li, cov neeg tsav tsheb lub tsheb thauj khoom).
Tawm quab yuam cov lus teb (ob qho tib si sib txawv) ua kom muaj kev tswj xyuas meej, zam kev thauj khoom sway lossis tshuab jerking thaum nres.
4.4 4. Rugged rau Industrial Environments
Tag nrho cov khoom hlau (pedal, txuas, nres ncej) yog coated nrog epoxy resin (60-80μm thickness) rau IP54 tiv thaiv, tiv thaiv plua plav, noo noo, thiab corrosion tsis kam.
Kev vibration-cov khoom siv tiv thaiv (cov txiv ntseej xauv, lub caij nplooj ntoos hlav ntxhua) tiv thaiv cov khoom xoob hauv siab - cov khoom siv vibration (xws li, me me winches).
