CovYLZ Seriesyog ntau yam ntawm kev lag luam -qib hydraulic log brakes engineered rau kev tswj braking ncaj qha ntawm lub log ntawm hnyav- lub luag haujlwm ntawm lub xov tooj ntawm tes thiab lub tshuab ruaj khov, suav nrog cov chaw nres nkoj cranes, cov tsheb thauj khoom tsuas, tsheb tsim kho, gantry cranes, thiab cov khoom siv- tuav cov khoom siv. Characterized los ntawm nwsdirect log -mounted tsimthiabhydraulic actuation, cov koob no muab lub zog nres siab, kev ua haujlwm ruaj khov, thiab kev tuav pov hwm kev ruaj ntseg - tseem ceeb rau cov ntawv thov uas xav tau lub log nrawm tswj lossis nres thaum muaj xwm txheej ceev (xws li cov tsheb thauj khoom qis qis, chaw nres nkoj tuav). Nrog rau kev tsom mus rau kev ua haujlwm ntev, kev cuam tshuam, thiab kev hloov pauv mus rau qhov chaw hnyav, YLZ Series tau siv dav hauv cov chaw nres nkoj, mines, chaw tsim kho, thiab chaw thauj khoom. 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
Lub YLZ Series (Y=Hydraulic, L=Log- Mounted, Z=Hnyav- Lub Luag Haujlwm) txhais los ntawm nwsdirect log kev koom ua ke, distinguishing nws los ntawm ncej-mounted nruas los yog disc brakes. Nws cov haujlwm tseem ceeb yog tsim los rau cov tshuab log thiab hnyav-load scenarios:
Dynamic Log Braking: Decelerating lossis nres cov khoom siv log (piv txwv li, tsheb thauj khoom, tsheb thauj mus los crane) nrog kev tswj lub zog kom tsis txhob skidding, load sway, lossis mechanical shock.
Static Wheel tuav: Kev ruaj ntseg machinery nyob rau hauv qhov chaw thaum lub sij hawm downtime, txij nkawm, los yog nyob rau hauv inclines (xws li, chaw nres tsheb mining tsheb nyob rau hauv qhov chaw siab tshaj, xauv lub crane log thaum thauj khoom).
Kev Tiv Thaiv Thaum Muaj Xwm Ceev -Skid Braking: Tsis siv neeg ua haujlwm tsis raug (piv txwv li, hydraulic siab poob, overspeed) los tiv thaiv lub log xauv - nce thiab cov khoom siv khiav tawm - tseem ceeb rau siab - kev pheej hmoo ua haujlwm zoo li kuv lub tsheb thauj khoom.
Npog lub log diameters los ntawm 400-1,500mm thiab torque outputs ntawm 5,000-50,000 N·m, series caters rau hnyav- lub luag hauj lwm loads (50-500 tons) thiab loj wheeled machinery.
2. Txoj Cai Ua Haujlwm
YLZ Series ua haujlwm ntawm ahydraulic clamping txoj cai, qhov twg hydraulic siab tsav tsheb nres kom clamp ncaj qha mus rau lub log rim los yog ib tug tshwj xeeb nres disc mounted ntawm lub log hub. Nws lub voj voog ua haujlwm suav nrog peb lub xeev tseem ceeb:
2.1 1. Nres Tso Tawm (Kev ua haujlwm ib txwm muaj)
Thaum lub tshuab (piv txwv li, ib qho chaw nres nkoj RTG crane) nyob rau hauv kev txav, lub zog tswj tau muab cov hydraulic siab (10-25 MPa) rau tus nres lub tog raj kheej hydraulic.
Cov cylinders pressurized retract, rub lub nres nres ntawm lub log / disc thiab tsim qhov sib txawv (0.5-1.0mm). Lub log tig ywj pheej, ua kom muaj kev mus los lossis ua haujlwm.
2.2 2. Kev Sib Txuas Nres (Controlled Stopping/Holding)
Tswj nres: Yuav kom qeeb lossis nres lub tshuab, lub tshuab tswj kom txo qis hydraulic siab. Internal rov springs (los yog txo lub siab) thawb lub nres nres tiv thaiv lub rotating log rim / disc.
Torque Generation: Kev sib txhuam ntawm cov ntaub qhwv thiab lub log sib cuam tshuam ua rau lub zog ntawm lub zog, nrog rau qhov sib npaug ntawm qhov hydraulic siab - tso cai rau kev sib tw, kho tau qeeb (xws li, cov tsheb thauj khoom tsuas yog nqis los).
Static tuav: Rau qhov chaw nres tsheb lossis thauj khoom ruaj ntseg, hydraulic siab tso tawm tag nrho. Rov qab springs (los yog mechanical lock) khaws cov ntaub qhwv rau lub log, tuav lub zog kom tuav lub tshuab ua haujlwm tsis muaj zog.
2.3 3. Emergency Braking (Fault Scenarios)
Nyob rau hauv cov ntaub ntawv ntawm hydraulic siab poob, overspeed (kuaj los ntawm lub log ceev sensors), los yog tus neeg teb xov tooj input thaum muaj xwm ceev, lub nres nres tam sim ntawd.
Rov qab springs (los yog backup hydraulic accumulators) tsav lub ncoo tiv thaiv lub log nrog lub siab tshaj plaws quab yuam, tsim lub ncov torque kom nres lub log nyob rau hauv tsawg tshaj li los yog sib npaug rau 1.0 thib ob (nyob rau hauv rated load)- tiv thaiv skidding los yog khiav.
