Kev Xaiv Cov Cai Rau Kev Yuav Cov Hlau Hlau Ropes Rau Cranes
Hlau ropesFeem ntau siv rau hauv kev tsim kho cranes thiab feem ntau yog ua los ntawm ntau lub zog steel hlau.
Nws thawj zaug muaj ib leeg hlau hlau raug mob ua ke los ua cov hlua, tom qab ntawd qee qhov ntawm cov hlua tau raug mob rau hauv cov hlua hlua, thiab cov hlua sab nrauv uas muaj lwm cov hlua raug mob nyob ib ncig ntawm cov tub ntxhais los ua ib txoj hlua hlau.
Qee cov hlau xaim hlua kuj tseem muaj cov yas ferrule hauv, feem ntau yog nyob rau hauv daim ntawv ntawm cov yas txheej uas tshwj xeeb kho kom npog cov hlua hlua, thiab cov hlua hlau tseem ceeb ntawm cov hlua hlau yog muaj cov roj nplua nyeem tsim nyog hauv cov hlua kom txo tau.kev sib txhuam.
Cov hlua hlau hlau feem ntau muab faib ua peb hom raws li cov khoom siv hlua: cov khoom siv organic (hemp core thiab paj rwb core), asbestos core lossis hlau core, thiab feem ntau tsis muaj cov khoom siv los yog roj nplua nyeem hauv txoj hlua.
Hlau hlua hlua tuaj yeem muab faib ua rau pem hauv ntej winding hlua thiab cross winding hlua raws li kev sib koom ua ke ntawm cov hlau xaim winding rau hauv cov hlua thiab cov hlua rau hauv cov hlua, thiab raws li kev sib tw ntawm cov hlua, nws tuaj yeem muab faib ua sab laug thiab sab xis. tib cov kev taw qhia thiab sab laug thiab txoj cai alternating nteg;
Ordinary steel hlau ropes zoo li tig mus rau qhov sib txawv ntawm txoj hlua hlau thaum lawv siv ib leeg. Thaum siv rau hauv ib lub pulley thaiv, kev sib hloov ntawm cov hlua hlau yuav ua rau cov hlua khi hlua khi, feem ntau hu ua twisting.
Piv nrog rau cov hlau zoo tib yam hlau hlua, cov hlau tsis tig hlau hlua tau pib siv dav.
Lub thiaj li hu ua non-rotating steel hlau hlua yog raws li lub hauv paus ntsiab lus hais tias lub torsional lub sij hawm ntawm cov hlua thiab cov strands yog nyob rau hauv lub opposite kev taw qhia tab sis sib npaug zos rau qhov loj; qhov txawv txav tsis-rotating steel hlau hlua yog txawv, thiab lub hauv paus ntsiab lus yog ua rau kev sib hloov kev taw qhia ntawm cov hlua core opposite rau cov hlua nws tus kheej. Thaum muaj kev ntxhov siab, lub zog torque tsim los ntawm cov hlua tseem ceeb yog sib npaug ntawm qhov loj rau qhov uas ua los ntawm cov hlua sab nrauv, tab sis rov qab rau hauv kev coj.
Cov hlua ntawm cov hlua hlau hlau kuj tuaj yeem ua rau hauv cov hlua khi los ntawm kev ua haujlwm tom qab xws li dov lossis tuag extrusion. Tom qab kev kho mob, txoj kab uas hla ntawm cov strands yuav raug txo, thiab qhov chaw tiav yuav siab heev.
Yog li ntawd, steel hlau hlua nrog compact strands tuaj yeem siv cov hlau hlau tuab. Nyob rau hauv tib txoj kab uas hla, steel hlau hlua nrog ntom strands muaj ib tug ntau dua filling coefficient thiab lub tawg quab yuam yog zoo heev.
Thaum muaj ntau txheej txheej winding yog nqa tawm ntawm lub reel, cov txheej txheej ntawm cov hlua steel hlau hlua yog nruj dua nruj ntawm cov khaubncaws sab nraud povtseg, thiab saum npoo ntawm cov hlau hlau hlua hnav sai dua. Lub nruj-strand steel hlau hlua muaj ntau dua hnav tsis kam thiab extrusion kuj.
Txawm hais tias kev xaiv cov hlua hlau hlau yog qhov tseeb lossis tsis ncaj ncees yuav cuam tshuam ncaj qha rau kev pabcuam lub neej ntawm txoj hlua thiab ua rau cov qauv deformation, tawg thiab tsis ua haujlwm ntawm txoj hlua. Yog li ntawd, cov txheej txheem xaiv tau pom zoo yog raws li hauv qab no:
1. Thaum nqa ib qho kev nqa hnyav uas tsis muaj kev taw qhia lossis ntau yam tsis siv neeg nqa hnyav ntawm qhov siab loj, siv txoj hlua tsis-rotating;
2. Cov hlua hlau zoo tib yam tuaj yeem siv tau thaum nqa ib lub nqa nqa nrog kev taw qhia qhov hnyav lossis ntau lub nqa nrog kev taw qhia qhov hnyav ntawm qhov siab me me (xws li tsav tsheb) lossis siv cov hlua sab laug thiab sab xis ua khub.
Cov kev taw qhia ntawm kev sib hloov ntawm cov hlua hlau yuav tsum tau txiav txim siab raws li hauv qab no: sab laug-tes steel hlau hlua yog pom zoo rau txoj cai-tes hlua groove nruas; ntawm qhov tsis sib xws, txoj cai-tes steel hlau ropes yuav tsum tau siv rau sab laug-tes hlua zawj nruas.
Rau cov uas tsis yog-rotating steel hlau ropes raug mob nyob rau hauv ib txheej, cov txheej txheem saum toj no yuav tsum tau ua raws li nruj me ntsis raws li, txwv tsis pub nws yuav yooj yim rau deformation mus tas li deformation ntawm cov hlau hlua qauv; zoo foundation.
Kev sib txhuam ntawm cov hlau hlua hlau thiab lub zog extrusion ntawm ntau txheej winding nruas yog qhov loj, uas yooj yim ua rau txoj hlua tsis sib haum. Yog li ntawd, cov hlua hlau steel nrog ib txoj kab uas hla me ntsis me dua lub suab ntawm txoj hlua hlua thiab txoj kab uas hla ntawm txoj hlua hlua yuav tsum tau xaiv los ua kom qhov kev ncua deb ntawm cov hlua hlau thiab lub nruas. Qhov chaw sib cuag ntawm lawv txo qhov kev sib txhuam ntawm cov hlua hlau uas nyob ib sab, yog li txhim kho lub neej ntawm cov hlau hlau ropes. Kev xyaum tau ua pov thawj tias txoj kab uas hla ntawm cov hlua hlau hlau yog 1 feem pua tsawg dua qhov kev sib tw ntawm txoj hlua hlua, uas pab kom cov hlua khi kom nruj thiab tshem tawm cov xwm txheej ntawm txoj hlua nce toj thiab hlua chaos.
Nyob rau hauv tib txoj kab uas hla, qhov ntau ntawm cov xov hlau sab nraud ntawm cov hlua hlau, qhov thinner txoj kab uas hla, thiab lub thinner ib leeg hlau hlau. Hom steel hlau hlua no muaj qhov yooj yooj yim thiab tuaj yeem kov yeej qhov rov qab khoov quab yuam thaum cov hlau xaim hlua nkag thiab tawm ntawm lub nruas ntau zaus. , Nws kuj yog ib qho yooj yim rau xov txoj hlua.
Lub thicker txheej strands, nrog lawv cov xov hlau tuab, zoo dua tuaj yeem tiv thaiv kev puas tsuaj, kev puas tsuaj, corrosion thiab crushing rog. Yog li ntawd, tsuas yog kev sib xyaw ua ke zoo ntawm ob qhov zoo tuaj yeem ua tau zoo steel hlau hlua nrog kev ua haujlwm siab tiag tiag.
Tsis tas li ntawd, thaum lub sij hawm xaiv cov hlau hlua hlau, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau nws txoj kab uas hla thiab qhov tsawg kawg nkaus tawg quab yuam, uas yuav tsum tau ua raws li cov kev cai ntawm tus qauv.
