Lub hoist brake ua haujlwm li cas?
Lub hoist nres yog kom ceev nrooj rotating qhov chaw los ntawm kev sib txhuam. Nyob ntawm lawv cov kev tsim kho thiab kev siv, kev lag luam brakes tuaj yeem muab faib ua ntau hom, xws li disc brakes, nruas nres, thiab band nres. Txawm li cas los xij, lawv txoj hauv kev ua haujlwm tseem ceeb yog kom ua tiav braking los ntawm kev hloov lub zog kinetic rau hauv tshav kub los ntawm kev sib txhuam ntawm cov khoom siv braking (xws li lub nres nres los yog band) thiab ib qho rotating (xws li brake disc lossis nruas).
Tshwj xeeb, thaum tus nres tau txais lub teeb liab braking, lub braking caij, nyob rau hauv lub zog ntawm sab nraud quab yuam (xws li cua siab, hydraulic siab, los yog electromagnetic quab yuam), compresses lub rotating ib feem, generating txaus kev sib txhuam kom qeeb lub rotating ib feem kom nres. Thaum lub sijhawm ua haujlwm no, tus nres yuav tsum tiv taus qhov kub thiab txias kom ntseeg tau tias kev ua haujlwm ruaj khov txawm tias nyob rau hauv huab cua.
Common hoist brakes feem ntau muab faib ua peb hom:hydraulic disc nres, hydraulic nruas nresthiabelectromagnetic nres.
Yuav ua li cas tswj hoist brakes
Raws li qhov tseem ceeb ntawm kev nyab xeebthaum lub winch ua haujlwm, tus nres yuav tsum tau saib xyuas tsis tu ncua kom ntseeg tau tias nws muaj kev ntseeg siab.
Kev tshuaj xyuas tsis tu ncua
Ua raws li cov lus qhia hauv phau ntawv qhia thiab kho qhov kev khiav hauj lwm ntawm lub caij nplooj ntoos hlav nres thiab khau kom ntseeg tau tias lawv koom nrog thaum lub hwj chim tawm thiab tso tawm thaum lub hwj chim qhib.
01
Ua kom huv si
Qhov chaw ua haujlwm ntawm lub log tsheb yuav tsum tiaj tus thiab du. Qhov chaw sib chwv ntawm tus brake khau thiab lub log nres yuav tsum tsis pub tsawg tshaj 80%. Cov roj thiab dej yuav tsum tau zam kom tsis txhob kis tus kab mob ntawm lub log, ua rau kev swb thiab nres nres.
02
Tshawb xyuas cov khoom tseem ceeb
Yog hais tias lub caij nplooj ntoos hlav tawg los yog deforms thiab tsis rebound, cov khoom puas yuav tsum tau hloov. Tshawb xyuas cov nplais hnav tsis tu ncua; yog tias hnav ntau tshaj 2 hli, hloov nws tam sim ntawd.
03
Tsis txhob muaj teeb meem
Khaws cov brakes kom deb ntawm dej thiab roj. Yog tias koj muaj kev swb lossis ua haujlwm tsis zoo, kaw lub tsheb tam sim ntawd thiab kho.
04
Hauv qab no yog ib lub rooj los pab koj nkag siab sai sai thaum nws yog lub sij hawm los hloov qhov tseem ceeb nres.
| Xyuas cov khoom | Hloov Standard | Lus hais |
| kev sib txhuam hauv ob sab phlu | Hloov thaum hnav mus txog 50% ntawm cov thawj hauv ob sab phlu. | Asbestos brake pads yuav tsum tau hloov thaum hnav tshaj 2 hli. |
| Nres Log | Hloov thaum hnav nto mus txog 2-3mm. | Lub log ntawm lub log khiav yuav tsum nyob twj ywm thiab du. |
| Springs |
Hloov tam sim ntawd yog tias muaj kab nrib pleb lossis cov yas deformation tshwm sim. |
Springs kuj yuav tsum tau hloov yog tias muaj deformation mus tas li. |
| Pin/Axle Qhov | Hloov thaum txoj kab uas hla coj mus txog 5% ntawm thawj txoj kab uas hla. | Kev hnav hnyav ntawm tus pins thiab lub qhov axles yuav ua rau kom poob mus los ntawm tus nres solenoid. |
| Nres Clearance | Kho qhov kev tshem tawm ntawm cov khau nres thiab lub log nres yog tias nws siab tshaj 0.8-1.6 hli. | Kev tshem tawm tsis sib xws kuj tuaj yeem ua rau hnav tsis sib xws thiab yuav tsum tau hloov kho. |
| Kev ua haujlwm txawv txav | Tsis zoo braking kev ua tau zoo, tsheb slippage, los yog nres nres ntau heev uas tiv thaiv tag nrho tso tawm. | Qhov kev ua yuam kev hauv nruab nrab ntawm lub log nres thiab lub khau nres yog qhov loj heev (ntau dua 3 hli) lossis qhov nruab nrab yog qaij. |
Hoist brakes qhov zoo
Hoist brakes tau siv dav hauv ntau hom cranes, ntauwd cranes, gantry cranes, thiab lwm yam khoom siv, muab cov txiaj ntsig hauv qab no:
Kev ntseeg siab: Lawv muab lub zog braking thaum muaj xwm txheej ceev, tiv thaiv kev thauj khoom los ntawm kev zawv zawg thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv.
High Automation: Cov qauv kaw ib txwm tso cai rau lub nruas nres kom siv lub nres thaum muaj kev ua haujlwm tsis zoo lossis kaw, txo qhov kev pheej hmoo ntawm tib neeg yuam kev.
High Adaptability: Hydraulic thiab electromagnetically actuated nruas nres yog tsim rau cranes ntawm ntau qhov ntau thiab tsawg thiab tuaj yeem ua tau raws li cov kev xav tau ntawm kev thauj khoom siab thiab siab - zaus ua haujlwm.
Kev Kho Kom Yooj Yim: Lub nruas nres qhov yooj yim tsim tso cai rau kev saib xyuas yooj yim, tso cai rau kev sib txhuam txhuam thiab kev tshuaj xyuas lub cev raws li xav tau los xyuas kom meej ntev - lub sijhawm ua haujlwm ruaj khov.
