Crane Nres
Lub nres yuav tsum ua raws li cov nram qab no:
A. Lub zog nres tuaj yeem tsim tawm kom tau raws li qhov xav tau.
B. Lub tshuab siv xoob xoob thiab lub xauv lub nrig yog nrawm thiab ruaj khov, thiab cov txav ntawm crane nres yog qhov tseeb thiab txhim khu kev qha
C. Kev hnav tsis kam thiab tshav kub tsis ua hauj lwm ntawm qhov kev sib txhuam yog qhov zoo.
D. Kev cog lus ntawm lub cev thiab me me.
E. Kev kho kom yooj yim thiab kho kom yooj yim.
Hom nres tau muab faib ua hom thaiv, hom siv thiab hom disk raws li cov qauv; raws li lub xeev ua haujlwm, muaj ob hom ntawm ib txwm kaw hom thiab nquag qhib hom.
Nquag kaw cov nres: thaum tshuab tsis ua haujlwm, kev ua haujlwm nres; thaum lub tshuab ua haujlwm, lub nres tawm.
Nquag qhib hom nres: tus nres feem ntau hauv lub xeev tso tawm, tsuas yog thaum yuav tsum tau ua.
Cov qauv thiab hom thaiv nres
Qhov zoo: thaiv nres tus qauv yog yooj yim, yooj yim nruab thiab kho, kho dav siv ntau hom hluav taws xob crane.
Cov kab hluav taws xob sib cais tau muab faib ua electromagnetic block nres thiab hydraulic nres thaiv.
Lub tshuab hluav taws xob nres hluav taws xob tau muab faib ua luv luv thiab qhov deb ntev.
tshuab hluav taws xob thaiv hluav taws xob
Luv stroke electromagnetic thaiv nres
Qhov zoo: ntawm tus nres, nres sai dua; ntim me me thiab lub teeb hnyav; txoj hlua khawm kev tuag tsawg dua yog me; thiab tus brake pad nres sab caj npab, lub log nres thiab tus tswj nres tsuj tus tsej tsuj coj khaub ncaws tsis sib xws.
Qhov tsis zoo: qhov nqus tau tsawg, feem ntau siv rau hauv lub sijhawm nres me dua cov koomhaum, cov log nres tsis loj dua 300 hli.
Yog li no, thaum lub tshuab kaw tus pas loj, lub tshuab hluav taws xob thaiv hluav taws xob yuav tsum yog cov neeg mob stroke ntev.
Piv nrog rau hydraulic nres nres, hluav taws xob thaiv hluav taws xob nres loj tsis zoo yog lub tshuab hluav taws xob loj, ua rau lub tshuab ntawm kev co.
Vim tias qhov pib nquag, nres thiab hluav taws xob sib tsoo, lub neej kev pab cuam ntawm electromagnet yog txo, yog li nws yog qhov yuav tsum tau kho thiab hloov nws ntau zaus.
Hydraulic laub pas nrig nres tsheb
Lub hydraulic laub qws ntaus tawm hauv hydraulic laub pas nrig nres, yog ib qho kev ywj pheej ntawm tus nqaj hlau txuas mus rau hluav taws xob hydraulic laub pas nrig thiab electromagnetic hydraulic thawb pas nrig.
Fais hydraulic laub pas nrig:
Cov tswv yim zoo: kev txav du; unit lub sijhawm ntawm kev sib koom tes siab, thawb tas mus li; lub cev muaj zog me me.
Kev tsis zoo: vim qhov loj inertia ntawm lub cev muaj zog thiab lub zog tsav tsheb, lub sijhawm ntev ntawm kev nres thiab tso tawm, nws tsis tsim nyog rau kev nqa lub tshuab.
Electromagnetic hydraulic thawb qws:
Qhov zoo: ob qho tag nrho hydraulic nres thiab electromagnetic nres ob qhov zoo, nres ruaj khov, tsis muaj suab nrov, txhim khu kev ua haujlwm, lub neej ntev.
Kev tsis zoo: cov qauv txheej txheem, tus nqi siab, nyuaj rau kev saib xyuas, kev nrov npe thiab kev thov yog qhov tsawg.
Kev siv nyab xeeb tus tsuj
Qhov ntseeg tau ntawm tus nres tseem ceeb heev. Ua ntej tshaj, tus qauv thiab kev ua tiav ntawm lub nres yuav tsum yog mastered. Qhov txhaum thiab nws cov laj thawj yuav tsum yog qhov tseeb. Nws yuav tsum tau soj ntsuam thiab kev tu xyuas tas li.
Cov kev txhaum ua thiab cov laj thawj
a. Qhov tsis txaus hluav taws xob nres:
Kev sib nraus los sis lub log nres hnav ua si hnyav lossis qee yam tsis zoo;
Muaj cov roj stain lossis xoob lub caij nplooj hlav tseem ceeb ntawm txoj siv nres thiab lub log nres;
Qee qhov yog nyam, hnav, xoob thiab lwm yam, xws li txav pob khawm clamping, xauv lub txiv ntseej xoob xoob, ua rau hloov kho lub zog xoob;
Lub kaw lus tsav ntawm lub hauv paus nres yog inflexible.
b.The tus nres poob nthav:
Kev hnyav los yog kev puas tsuaj ntawm txoj siv sia nres;
Qhov ntev stroke lub tshuab hluav taws xob tau daig lossis pas nrig tau poob ntawm nruab nrab ntawm lub armature thiab lub zog tav toj.
Lub hauv paus tseem ceeb raug puas lossis lub ntsiab caij nplooj ntoo hlav tsis zoo;
Hydraulic laub pas nrig lossis hydraulic electromagnetic laub pas nrig tsis txav;
Hluav taws xob tsis ua haujlwm thiab lwm yam.
Soj ntsuam thiab tu cov nres
Kev sib tsoo ntawm lub tshuab nqa cov tshuab yuav tsum raug kuaj xyuas txhua qhov haujlwm pib; tus nres ntawm lub tshuab khiav yuav tsum raug kuaj xyuas txhua ob rau peb hnub.Qhov kev soj ntsuam: Kev hloov cov kab ke ntawm cov nres; Lub log tsheb; Siv tawv siv; Cov tshuaj sib zog cov qib; Kev kaw lus hydraulic.
Kev siv nyab xeeb tus tsuj
Tom qab tus brake hloov kho, qhov kev sib txawv ntawm tus braking, lub zog nres thiab nqa lub nraub qaum yuav tsum tau sim ua ntej siv ntawm tus nres, thiab kev ua haujlwm tuaj yeem ua tau tom qab qhov kev ua haujlwm ib txwm tau lees paus.
Tom qab tus brake raug kaw, qhov khoom raug tshem tawm lossis lub cev tsheb yuav tsum muaj lub zawv zawg nyob hauv chav tsev lub sijhawm, uas yog, inertia stroke.
Inertial mus ncig ua si yog hu ua tus braking deb thaum rub thauj cov kabmob.
Kev siv lub tshuab ua haujlwm: kev sib nrig sib nrug yog li 7% ntawm qhov khiav nrawm (m / min).
Lifting mechanism: braking nrug yog li ntawm 1% ntawm qhov nqa ceev (m / min).
Tus nres yuav tsum muaj peev xwm ntseeg siab tiv taus 1.25 zaus ntawm cov ntaus nqi ntsuas.
Ua ntej txhua txoj haujlwm, qhov khoom yuav tsum raug tshem tawm hauv av 100 ~ 200 hli, txhawm rau soj ntsuam seb qhov haujlwm nres puas zoo li qub. Tom qab paub meej tias ib txwm, koj tuaj yeem pib ua haujlwm.
Crane Nres
Lub luag haujlwm tseem ceeb: txhawb kev ua haujlwm; sab nraub qaum cov nyhuv; overrunning clutch muaj nuj nqi.
Cov thau khoom siv tshwj xeeb yog: cov log log; cov menyuam hom; siv tawv.
