Vim li cas xaiv txoj cai Crane Nruas thiaj tseem ceeb?
Lub nruas crane yog lub hauv paus tseem ceeb ntawm txoj hlua hlau ua haujlwm, lub luag haujlwm tseem ceeb ntawm txoj hlua hlua winding, hlua cia, thiab xaim lifting quab yuam.
Tau ntsib nrog ntau yam ntawm crane nruas nyob rau hauv kev ua lag luam, koj puas tau xav tsis meej pem, tsis paub tseeb tias ib qho twg haum rau koj cov khoom nqa nqa thiab kev ua haujlwm? Xaiv txoj caicrane nruastsis yog ib qho teeb meem yooj yim ntawm qhov loj me; nws yog qhov kev txiav txim siab tseem ceeb txog kev ua haujlwm tag nrho ntawm cov cuab yeej siv, cov ntaub ntawv kev nyab xeeb, thiab cov nqi ua haujlwm ntev -. Ib lub nruas uas tsis raug xaiv tuaj yeem ua rau hnyav hnyav, derailment, compression deformation, thiab txawm tias hlua tawg hauv lub sijhawm luv.
Kev txiav txim siab Crane Nruas Lub Zog Yuav Tsum Tau Raws Li Lifting Peev Xwm thiab Chav Ua Haujlwm
Lub crane lub peev xwm nqa tau txiav txim siab qhov kev ntxhov siab ntawm lub nruas yuav tsum tiv taus, thaum "chav ua haujlwm" (A3-A7) qhia txog kev ua haujlwm txhua hnub thiab kev siv zog. Cov yam tseem ceeb no cuam tshuam ncaj qha rau lub crane nruas phab ntsa thickness thiab tag nrho cov qauv lub zog.
Piv txwv li:
• 5-20 tuj cranes feem ntau siv nruas phab ntsa thicknesses ntawm 16-36 hli rau nruab nrab loads thiab nruab nrab siv zaus.
• Cov khoom siv ntau tshaj 50 tons yuav tsum nruas phab ntsa thicknesses ntawm 45 mm los yog ntau tshaj los xyuas kom meej txaus bending thiab qaug zog kuj nyob rau hauv siab load.
Hauv qib siab -qib (A5–A7) kev khiav hauj lwm, crane drums yuav tsum tsis tsuas yog ua tau raws li qhov yuav tsum tau muaj zog zoo li qub, tab sis kuj tseem ua kom muaj zog ntsuas kom txo tau kev co thaum lub sijhawm ua haujlwm siab -. Cov kev tshawb fawb qhia tau hais tias kev tsis sib haum xeeb tuaj yeem txo tau lub neej ntawm 15-25%, ua rau nws tseem ceeb tshwj xeeb rau cov khoom nruab nrab thiab hnyav- cov khoom siv ua haujlwm.
Matching Crane Drum Sizes rau Hlau Rope Specifications
Ib qho ntawm qhov tseem ceeb tshaj plaws hauv crane nruas tsim yog D / d piv (nruas txoj kab uas hla ÷ hlau hlua txoj kab uas hla).
Qhov ntau yam tsim nyog feem ntau yog nyob nruab nrab ntawm 18-22, uas txo qis kev qaug zog ntawm txoj hlua hlau. Yog tias qhov sib piv D / d tsawg dhau, qhov kev ntxhov siab khoov ib zaug ntawm txoj hlua hlau yuav nce ntxiv, uas tuaj yeem txo nws txoj sia ntawm 40-60%.
Tsis tas li ntawd, txoj hlua groove geometry kuj tseem ceeb heev:
• hlua zawj qhov tob=0.25–0.35 npaug ntawm txoj hlua hlua
• Helix lub kaum sab xis=6℃-12 degree, ua kom txoj hlua zoo sib xws thiab tiv thaiv txoj hlua hlau hla ntawm qhov zawj
• Groove spacing=1.04–1.1 npaug ntawm txoj kab uas hla txoj kab uas hla, tiv thaiv compression.
Precisely txuam cov hlua grooves tuaj yeem txo cov hlua khi los ntawm 20-30%, ib txoj hauv kev ncaj qha mus txuas ntxiv lub neej ntawm cov khoom siv.
Xaiv cov khoom siv thiab kev siv tshuab raws li kev ua haujlwm
Cov khoom siv ntawm lub nruas crane cuam tshuam rau nws lub zog, hnav tsis kam, thiab qaug zog lub neej. Cov kev khiav hauj lwm sib txawv xav tau cov ntaub ntawv sib txawv thiab cov txheej txheem kho cua sov.
Khoom siv:
• Q235 / Q345: Haum rau cov khoom siv cranes, tus nqi siab -kev ua tau zoo
• 45# steel, Q355, 16Mn: Haum rau siab - siv zog
• High corrosion-resistant steel los yog cov ntaub ntawv sib xyaw: Siv nyob rau hauv corrosive ib puag ncig xws li marine engineering thiab tshuaj industries.
Tom qab tempering (quenching + tempering), lub zog ntawm lub nruas tuaj yeem nce los ntawm 20-35%, txhim kho kev qaug zog.
Rau sab nraum zoov lossis marine ib puag ncig:
• Nws raug pom zoo kom siv epoxy zinc-nplua nuj primer + topcoat system nrog lub thickness ntawm ntau dua los yog sib npaug rau 150µm.
• Xwb, cov khoom siv hlau lossis hlau tsis muaj hlau tuaj yeem siv tau.
Kev xaiv cov khoom tsim nyog tuaj yeem ua ob npaug ntawm lub nruas lub neej thaum txo kev txij nkawm.
Xyuas kom lub crane nruas qauv yog sib xws nrog cov khoom siv system
Cov qauv sib txawv sib txawv tsim cov kev cai sib txawv ntawm crane nruas installation. Lub nruas ncej kawg, txoj hauv kev tseem ceeb, thiab kev sib txuas sib txuas yuav tsum tau ua tiav nrog cov qauv tshuab loj; txwv tsis pub, eccentricity, vibration, lossis bearing overload yuav tshwm sim.
Piv txwv li:
• Cov radial load uas cov kabmob vaj tse tuaj yeem tiv taus yog feem ntau 150-300 kN, thiab nws yuav tsum tau ua kom ntseeg tau tias lub nruas tsis pub dhau qhov nqi no thaum lub sijhawm ua haujlwm.
• Kev tsav ncaj qha yuav tsum muaj kev sib koom ua ke siab heev, feem ntau ua tiav qhov tseeb ntawm qhov tsawg dua lossis sib npaug li 0.05 hli.
• Chain tsav los yog coupling tsav yuav tsum tau ntxiv qhov chaw installation thiab xyuas kom meej installation cov ces kaum kom tsis txhob hnav tsis sib xws.
Cov kev sib raug zoo no txiav txim siab qhov smoothness ntawm lub crane nruas lub lag luam thiab tseem cuam tshuam rau tag nrho cov kev pab cuam lub neej thiab txij nkawm nyuaj ntawm lub tshuab.
Xaiv Tsim Nruas Tsim Nyog rau Kev Lag Luam Sib Txawv
Daim ntawv thov yuav tsum tau ntawm crane drums sib txawv heev nyob rau hauv txawv industrial sectors, yog li ntawd cov kev xaiv tseem ceeb kuj txawv.
Kev Lag Luam Metallurgical (High Temperature, Heavy Load)
• Metallurgical cranes yuav tsum tiv taus siab -kub hluav taws xob thiab nquag hnyav- thauj mus los; Yog li ntawd, lub nruas yuav tsum muaj lub zog siab, tiv taus cua sov, thiab lub neej ntev ntev.
Chaw nres nkoj Cranes (Hloov ceev, loj hlua muaj peev xwm)
• Kev khiav hauj lwm ceev
• Cov hlua loj muaj peev xwm (dhau 1000 meters)
• Ua rau ntsev tsuag thiab dej hiav txwv cua corrosion
Cov hlua kev teeb tsa thiab nto corrosion kuj ntawm lub crane nruas yuav tsum muaj zog ntxiv.
Marine / Nkoj Cranes (Highly Corrosive Ib puag ncig)
• Yuav tsum ua raws li ISO 4308 hlau hlua nruas qauv; corrosion kuj thiab qaug zog tsis kam yog qhov tseem ceeb, yuav tsum tau ua kom nruj dua txheej txheem kho.
