Nkag siab txog Load Nature thiab Inertial Characteristics ntawm Crane
Crane loads feem ntau muab faib ua lub zog muaj peev xwm loads (xws li kev txhawb nqa ntawm lub hoisting mechanism thiab luffing mechanism) thiab translational loads (xws li kev txhawb nqa ntawm lub slewing mechanism thiab mus ncig teb chaws mechanism). Qhov kev sib txawv no yog qhov tseem ceeb rau kev xaiv Port Crane Brake.
Cov txheej txheem ua haujlwm sib txawv kuj muaj qhov sib txawv inertial yam ntxwv. Piv txwv li, lub hoisting mechanism ntawm lub gantry crane yog suav tias yog ib qho qis -inertia mechanism, lub luffing mechanism yog nruab nrab -inertia mechanism, thaum lub slewing thiab mus ncig teb chaws mechanisms yog siab - inertia mechanisms. Kev txiav txim siab ntawm lub sij hawm braking yuav tsum xav txog tag nrho cov yam ntxwv inertial ntawm lub mechanism- lub sij hawm braking luv luv tuaj yeem raug xaiv rau cov txheej txheem nrog me me inertia, thaum lub sij hawm braking ntev yuav tsum tau siv rau cov mechanisms nrog inertia loj.
Nkag siab hom thiab yam ntxwv ntawm Chaw nres nkoj Crane Nres
Feem ntau siv ua haujlwm Chaw nres nkoj Crane Brakes rau qhov chaw nres nkoj cranes feem ntau yog ob lub qauv: hydraulic pushrod log hom thiab disc hom. Kev Nyab Xeeb Chaw nres nkoj Crane Nres nyob ntawm qhov qis - nrawm kawg ntawm qhov kev sib kis thiab tuaj yeem tsim kom muaj kev sib txhuam loj torque kom ua tiav lub hom phiaj ntawm kev ruaj ntseg braking. Lawv feem ntau txais yuav cov qauv hydraulically ua haujlwm disc lossis lub hub -thiab- siv qauv.
Disc Chaw nres nkoj Crane Brakes muaj ntau qhov zoo dua li cov tsoos log Chaw nres nkoj Crane Nres: qis inertia ntawm Chaw nres nkoj Crane Nres disc; Qhov sib txawv Port Crane Brake disc diameters tuaj yeem siv rau tib qhov chaw nres nkoj Crane Nres specification; cov ntaub ntawv sib txhuam siv tso cai rau kev khiav hauj lwm ceev dua thiab qhov chaw nres nkoj Crane Brake linings tuaj yeem tiv taus qhov kub thiab txias, muab kev ua haujlwm siab dua thaum muaj xwm txheej ceev; Cov ntaub ntawv tsis muaj kev sib txhuam yog siv, thiab lawv cov yam ntxwv kev sib txhuam tsis tshua muaj kev cuam tshuam los ntawm corrosion, muaj kuab paug, thiab av noo; lawv lub neej yog 50% mus rau 100% ntev dua li ntawm lub log Port Crane Nres.
Ua raws li Cov Ntsiab Cai ntawm Chaw nres nkoj Crane Nres Xaiv
Load matching lub hauv paus ntsiab lus: tsis yog qhov muaj zog qhov zoo dua, tab sis qhov tseeb ntau qhov zoo dua. Lub teeb- cov khoom siv thauj khoom (xws li lub log tsheb- cov cranes mounted) yuav tsum ua qhov tseem ceeb ntawm cov lus teb ceev thiab raug; hnyav- cov khoom siv thauj khoom (xws li quay cranes) yuav tsum ua qhov tseem ceeb ntawm kev ua haujlwm kub thiab kev cuam tshuam.
Environmental adaptability txoj cai: Chaw nres nkoj ib puag ncig yog complex, yuav tsum tau Port Crane Brakes muaj zogib puag ncig tsis kam: Cov chaw nres nkoj ntawm ntug dej hiav txwv yuav tsum xaiv cov khoom lag luam nrog ntau- txheej txheej dynamic sealing lug tiv thaiv cov ntsev tsuag nkag; plua plav ib puag ncig yuav tsum tau kaw Chaw nres nkoj Crane Brake chamber tsim los tiv thaiv cov xuab zeb thiab plua plav thaiv.
Lub hauv paus ntsiab lus ntawm kev saib xyuas yooj yim: Chaw nres nkoj ua haujlwm yog lub sijhawm-sensitive, thiab yooj yim ntawm kev saib xyuas ncaj qha cuam tshuam rau kev ua haujlwm zoo. Cov qauv tsim qauv yuav tsum yog qhov tseem ceeb, vim tias kev hloov cov ntaub thaiv kev sib txhuam tsis tas yuav tsum tau disassembling tag nrho lub tshuab, txuag lub sijhawm txij nkawm.
Peb lub ntsiab tseem ceeb
Environmental adaptability
"Muab Port Crane Brakes 'tiv thaiv armor'" yog qhov kev txiav txim siab tseem ceeb hauv kev xaiv chaw nres nkoj. Ntsev tshuaj tsuag corrosion nyob rau hauv cov chaw nres nkoj ntug hiav txwv tsim nyog tau txais kev saib xyuas tshwj xeeb, thiab ntau - txheej txheej txheej sealing yuav tsum nyiam; rau qhov chaw muaj plua plav, kaw Chaw nres nkoj Crane Brake chamber tsim tuaj yeem tiv thaiv cov xuab zeb thiab plua plav thaiv.
Load Matching
Xaiv tus qauv zoo raws li hom khoom siv yog qhov tseem ceeb. Lub teeb- khoom siv thauj khoom tseem ceeb ua ntej teb ceev thiab raug; hnyav- cov khoom siv thauj khoom tseem ceeb ua kom muaj cua sov thiab kev poob siab. Cov kws tshaj lij pom zoo tias kev muab cov cuab yeej siv tsis tau thiab muaj tus kws tshaj lij kho qhov braking torque nkhaus yog qhov kev coj ua zoo tshaj plaws.
Modular tsim tuaj yeem txuag lub sijhawm ua haujlwm tseem ceeb. Piv txwv li, qee qhov ceev - tso tawm cov qauv tso cai rau kev sib txhuam cov ntaub qhwv tsis tau disassembling tag nrho lub tshuab. Nws tseem yog ib qho tseem ceeb uas yuav tau xav txog qhov sib raug zoo nrog cov cuab yeej uas twb muaj lawm kom tsis txhob hloov cov nqi.
Cov lus pom zoo rau Chaw nres nkoj Crane Brakes siv thiab tu
Raws li cov qauv kev saib xyuas rau gantry cranes, kev tu txhua hnub yuav tsum tau ua txhua txoj haujlwm. Kev kho me me yuav tsum tau ua tom qab 1000 teev ntawm kev ua haujlwm, nruab nrab hloov kho tom qab 4000 teev, thiab kev kho dua tshiab tom qab 8000 teev.
Kev Ceeb Toom Tshwj Xeeb: Kev tswj xyuas overspeed rau kev nyab xeeb Chaw nres nkoj Crane Brakes feem ntau yog 1.1 ~ 1.2 npaug ntawm qhov ntsuas ceev, tab sis qhov chaw nres nkoj Crane Nres xaiv xam yog raws li 1.5 npaug ntawm qhov ntsuas ceev. Kev nyab xeeb chaw nres nkoj Crane Nres xaiv txawv ntawm qhov chaw nres nkoj Crane Nres xaiv; Kev xaiv lub zog ntawm lub braking rau kev nyab xeeb Chaw nres nkoj Crane Brakes tsis xav txog kev nyab xeeb vim tias kev nyab xeeb Chaw nres nkoj Crane Brakes tsuas yog qhib thaum muaj xwm txheej, uas yog lub xeev - tswj raws li.
Kev xaiv ntawm Chaw nres nkoj Crane Brakes rau qhov chaw nres nkoj cranes yuav tsum muaj kev xav txog ntau yam xws li cov cuab yeej siv, ib puag ncig ua haujlwm, tus yam ntxwv thauj khoom, thiab kev saib xyuas. Kev xaiv kom raug tsis yog tsuas yog ua kom muaj kev nyab xeeb ntawm kev ua haujlwm tab sis kuj txhim kho cov cuab yeej siv tau zoo thiab lub neej ntev. Hauv kev ua haujlwm ntawm chaw nres nkoj, thaj chaw uas muaj kev nyab xeeb siab heev, "kev nyab xeeb ua ntej" tsis yog lub tswv yim xwb tab sis yuav tsum tau ua los ntawm kev xaiv kom raug ntawm txhua qhov tseem ceeb.
Txawm hais tias xaiv cov cuab yeej tshiab lossis hloov kho cov cuab yeej uas twb muaj lawm, nqis peev hauvsiab -Qhov chaw nres nkoj Crane Brakes zoothiab tsim kom muaj lub suab tu qhov system thaum kawg yuav tsim kom muaj txiaj ntsig ntau dua rau kev ua haujlwm ntawm chaw nres nkoj.
