Kev Nyab Xeeb Kev Nyab Xeeb Ntawm Hlau Rope
Hlau hlua hnav
Thaum lub sijhawm ua haujlwm ntawm cov hlua hlau hlau, qhov kev ntxhov siab ntawm txhua txoj hlua hlau hlua yog qhov nyuaj heev, vim tias txoj haujlwm ntawm txhua txoj hlua hlau hauv txoj hlua sib txawv, qee qhov yog nyob rau hauv txheej txheej, thiab qee qhov yog nyob rau hauv txheej txheej. Txawm nyob rau hauv qhov yooj yim tensile quab yuam, lub zog faib yog txawv ntawm txhua txoj hlua hlau.
Lub reel yog ib qho tseem ceeb ntawm kev ntxhov siab ntawm crane. Thaum siv, lub nruas phab ntsa yuav thinned, qhov thiab tawg yuav tshwm sim.
Qhov ua rau ntawm cov kev ua tsis tiav no yog lub nruas thiab cov hlua hlau sib txuas thiab rub tawm ib leeg. Thaum lub nruas yog thinned mus rau ib qho twg, nws tawg vim nws tsis tuaj yeem tiv taus lub siab los ntawm qhovtxoj hlua.
Nws yuav tsum raug sau tseg tias kev hnav los ntawm cov hlua hlau tsis txwv rau kev hnav sab nraud, tab sis kuj hnav deformation tshwm sim los ntawm kev co, kev sib tsoo thiab lwm yam thiab kev hnav sab hauv los ntawm lub siab ntawm cov hlua hlau.
Hlau hlua qaug zog puas tsuaj
Hlau hlua hlua rau cranes feem ntau khoov, ncab, twisted, thiab vibrated thaum siv. Tom qab rov ua dua, kev qaug zog thiab tawg ntawm cov xov hlau yuav tshwm sim, tshwj xeeb tshaj yog nyob rau hauv cov hlau hlau hlua hauv cov theem tom qab ntawm kev siv huv. .
Txij li thaum khoov qaug zog lub neej ntawm cov hlua hlau yog ze ze rau txoj kab uas hla ntawm lub nruas, txoj kab uas hla ntawm cov hlua hlau, cov qauv ntawm cov hlua hlau, qhov kev nyab xeeb, thiab lwm yam. ib sab tes, nws yog ib qho tsim nyog yuav tau xaiv qhov tsim nyog ntawm cov hlua hlau raws li qhov yuav tsum tau siv. Thaum cov xwm txheej tso cai, txoj kab uas hla ntawm lub nruas thiab rub lub rub yuav tsum tau nce ntau npaum li qhov ua tau, thiab rov qab khoov ntawm txoj hlua hlau yuav tsum zam kom ntau li ntau tau.
Corrosion ntawm hlau hlua
Hlau hlua hlua rau cranes yog dav siv nyob rau hauv ncej hoisting, roj drilling, excavators, nkoj thauj khoom thiab unloading thiab lwm yam sij hawm. Nrog rau lub hnub thiab nag thiab kev siv mus ntev, yuav muaj qee qhov kev txhim kho corrosion, tshwj xeeb tshaj yog nyob rau hauv hnyav seaside thiab industrial scenes. ib puag ncig, qhov xwm txheej yuav hnyav dua.
Txhawm rau txo lossis zam qhov kev puas tsuaj ntawm cov hlau xaim hlua rau cranes, muaj ob txoj hauv kev uas feem ntau siv, ib qho yog siv roj, thiab lwm qhov yog siv galvanized steel hlau ropes.
Ceev faj
Thaum cov phab ntsa hnav ntawm lub reel nce mus txog 20 feem pua ntawm cov thawj lossis cov kab nrib pleb tshwm, nws yuav tsum tau hloov raws sijhawm.
Lub peev xwm nqa ntawm lub crane yuav tsum tsis txhob tshaj qhov ntsuas lifting peev thaum lub sijhawm ua haujlwm.
Cov hlua hlau ntawm lub crane yuav tsum raug xaiv raws li hom kev ua haujlwm thiab ib puag ncig.
Cov hlua hlau steel yuav tsum tau lubricated tsis tu ncua (txiav txim siab lub sijhawm lubrication raws li qhov chaw ua haujlwm).
Tsis txhob cuam tshuam cov hlua hlau kom muaj kev cuam tshuam sai thaum lub crane ua haujlwm.
Hlau hlua nyob rau hauv ib puag ncig uas muaj kub thiab corrosive media yuav tsum muaj cov khoom sib cais.
Ob qhov teeb meem yuav tsum tau them nyiaj mloog mus rau hauv kev soj ntsuam kev nyab xeeb ntawm kev sib txuas lossis kho cov hlua hlau nrog lwm cov khoom siv:
Ua ntej: txoj kev sib txuas lossis kev txhim kho yog ua raws li qhov yuav tsum tau siv;
Thib ob: Qhov kev sib txuas lossis qhov chaw ruaj khov ua tau raws li cov kev xav tau ntawm lub zog thiab kev nyab xeeb.
Feem ntau siv kev sib txuas thiab kho cov txheej txheem yog raws li hauv qab no:
1. Braided kev twb kev txuas
Lub braiding ntev yuav tsum tsis txhob tsawg tshaj li 15 npaug ntawm txoj kab uas hla ntawm txoj hlua hlau, thiab yuav tsum tsis pub tsawg tshaj 300 hli; qhov kev sib txuas lub zog yuav tsum tsis pub tsawg dua 75 feem pua ntawm qhov tawg ntawm cov hlua hlau.
2. Wedge, wedge txuas
Ib qho kawg ntawm txoj hlua hlau mus ncig ntawm lub npoo, thiab cov hlua hlau yog tsau los ntawm kev xauv cov nyhuv ntawm cov npoo ntawm lub tes tsho. Lub zog ntawm qhov chaw ruaj khov yog li 75 feem pua rau 85 feem pua ntawm lub zog ntawm txoj hlua nws tus kheej.
Lub tes tsho wedge yuav tsum yog ua los ntawm cov hlau, thiab lub zog txuas tsis pub tsawg dua 75 feem pua ntawm qhov tawg ntawm cov hlua hlau.
3. Txoj hlua txuas
Txoj hlua clamp txuas yog yooj yim thiab txhim khu kev qha, thiab yog siv dav.
Thaum kho nrog hlua clamps, yuav tsum tau them nyiaj mloog mus rau tus naj npawb ntawm cov hlua clamps, qhov kev ncua deb ntawm txoj hlua clamps, kev taw qhia ntawm txoj hlua clamps thiab lub zog ntawm qhov kho qhov taw tes.
(1) Lub zog sib txuas tsis pub tsawg dua 85 feem pua ntawm qhov tawg ntawm cov hlua hlau.
(2) Tus naj npawb ntawm cov hlua khi yuav tsum ua tau raws li qhov yuav tsum tau ua raws li txoj kab uas hla ntawm txoj hlua hlau.
Kev ruaj ntseg yuav tsum tau rau hlua Clamp txuas
(3) Cov hlua clamping phaj yuav tsum nyob rau sab ntawm qhov kawg ntawm txoj hlua hlau, thiab qhov kev ncua deb ntawm txoj hlua clamps yuav tsum tsis pub tsawg tshaj 6 npaug ntawm txoj kab uas hla ntawm txoj hlua hlau.
4. Kev sib txuas ntawm tapered tes tsho casting txoj kev thiab aluminium alloy tes tsho compression txoj kev, thiab lwm yam.
Tom qab qhov kawg ntawm txoj hlua hlau hla dhau lub tes tsho tapered, cov hlau hlau yog xoob, thiab cov hlau hlau ntawm lub taub hau yog khoov rau hauv ib qho me me nuv, uas yog poured rau hauv molten hlau thiab solidified.
Kev sib txuas yuav tsum ua kom tau raws li cov txheej txheem sib xws, thiab lub zog ntawm qhov ruaj khov yog roughly tib yam li cov hlua hlau hlau nws tus kheej.
