Hlau hlua hluav taws xob hoists yog tam sim no nrov khoom ntawm me me thiab lub teeb lifting khoom, feem ntau yog vim lawv muaj zog nqa peev xwm thiab efficiency. Cov phooj ywg uas paub txog cov hlua hluav taws xob hoists yuav tsum paub tias nws lub ntsiab traction yog cov hlua hlau. Piv nrog cov tsoos lifting chains, hlau ropes khiav zoo dua thiab tsis tas yuav txhawj txog cov saw tawg.
Cov hlua hlua ntawm txhua qhov hluav taws xob hoist tsis sib xws. Cov hlua hlau tshwj xeeb yog txiav txim siab raws li qhov ntsuas ntawm qhov hluav taws xob hoist. Qhov sib piv specifications yuav inevitably nce cov hlua txoj kab uas hla nrog cov rated load ntawm hluav taws xob hoist. Tsuas yog nyob rau hauv txoj kev no tuaj yeem lav qhov kev nyab xeeb ntawm kev nqa haujlwm. Yog li dab tsi yog qhov sib thooj specifications?
Cov khoom ntsuas ntawm cov pa hluav taws xob xaim hlua hoists feem ntau muab faib ua 1 tuj, 2 tons, 3 tons, 5 tons, 10 tons, thiab 20 tons. Lawv sib haum rau cov lus qhia ntawm cov hlua hlau ntawm 7.7mm, 11mm, 13mm, 15mm, 17.5mm, thiab 19.5mm feem. Tau kawg, cov hlua hlau tshwj xeeb ntawm 0.5 tuj hluav taws xob hlau hlua hoists yog 4.76mm lossis 5mm. Cov ntaub ntawv no tau txais los ntawm cov ntaub ntawv tshawb fawb nruj thiab tseem yog lub xeev zoo tshaj plaws hauv kev nqa cov haujlwm.
Nws tuaj yeem pom tias kev nyab xeeb ntawm kev siv hlua hlua hluav taws xob hoists tsis yog tsuas yog txiav txim siab los ntawm kev ua haujlwm tsis tu ncua thiab kev saib xyuas, tab sis kuj los ntawm kev sib txuam ntawm cov hlua hlau thiab hluav taws xob hoist. Yog li ntawd, peb ceeb toom rau koj tias thaum koj lub tshuab hluav taws xob hoist yuav tsum tau hloov nrog cov hlua hlau, koj yuav tsum nkag siab tias nws phim cov hlua hlau tshwj xeeb los tiv thaiv kev nyab xeeb los ntawm kev siv hluav taws xob hoist lifting.
Cov hlua hlau yog siv dav hauv ntau daim ntawv thov kev lag luam, tshwj xeeb tshaj yog hauv cov khoom nqa nqa, cranes, hluav taws xob hoists thiab conveying systems. Vim nws txoj haujlwm tshwj xeeb ntawm kev nqa cov khoom hnyav, cov hlua hlau yuav ntsib ntau yam teeb meem xws li hnav, corrosion, qaug zog, thiab lwm yam thaum siv mus ntev, yog li kev tiv thaiv ntawm cov hlua hlau yog qhov tseem ceeb. Cov hauv qab no yog ob peb txoj hauv kev ntawm kev tiv thaiv hlau hlua:
1. Txheej tiv thaiv
Lubricant txheej:
Kev siv cov roj nplua nyeem yog ib txoj hauv kev zoo tshaj plaws los tiv thaiv cov hlua hlau. Lubricants tuaj yeem txo qhov kev sib txhuam ntawm cov hlua hlau thiab cov kev sib txhuam sab nraud, txo qhov hnav, thiab tiv thaiv kom tsis txhob ya raws thiab cov khoom corrosive los ntawm kev nkag mus rau cov hlua hlau, yog li tsis txhob xeb.
Anti-xeb txheej:
Qee cov hlua hlau yog coated nrog cov tshuaj tiv thaiv xeb, xws li galvanized coatings lossis lwm cov txheej tiv thaiv corrosion, kom lawv cov corrosion kuj. Cov txheej txheej ntawm galvanized hlau hlua yog coated nrog ib txheej ntawm zinc, uas ua rau cov hlua hlau tsis tshua muaj xeb nyob rau hauv ib puag ncig ntub thiab ua rau nws lub neej kev pab cuam ntev.
2. Lub tes tsho tiv thaiv sab nraud
PVC los yog roj hmab tiv lub tes tsho:
Kev qhwv lub tes tsho mos los yog roj hmab tiv thaiv sab nraud ntawm cov hlua hlau tsis yog tsuas yog tiv thaiv cov hlua hlau los ntawm kev sib cuag ncaj qha nrog cov khoom siv sab nraud, tab sis kuj tseem tiv thaiv cov txheej txheej ntawm cov hlua hlau los ntawm kev hnav vim tsis tshua muaj kev sib txhuam. Lub tes tsho tiv thaiv kuj tiv thaiv cov hlua hlau los ntawm kev nkag los ntawm cov plua plav, tshuaj lom neeg lossis cov dej noo nyob rau hauv ib puag ncig sab nraud.
Hlau hlua casing:
Hlau hlua casing feem ntau yog siv nyob rau hauv high-siv daim ntaub ntawv los yog hnyav ib puag ncig, thiab tuaj yeem muab kev tiv thaiv ntxiv los tiv thaiv cov hlua hlau los ntawm kev tawg lossis puas thaum siv ntau zaus. Cov khoom siv casing feem ntau yog cov hlau muaj zog lossis cov khoom siv hluavtaws.
3. Anti-corrosion kho
Kub-dip galvanizing:
Tom qab kub-dip galvanizing kev kho mob, qhov saum npoo ntawm cov hlua hlau yog them nrog ib txheej zinc, uas zoo txhim kho nws cov corrosion kuj thiab yog haum rau corrosive ib puag ncig xws li offshore platforms, mines, thiab tshuaj nroj tsuag.
Kub galvanizing:
Txias galvanizing kuj yog ib txoj kev los tiv thaiv corrosion rau cov hlua hlau, uas yog tsim rau me me corrosive ib puag ncig, tab sis nws cov nyhuv tiv thaiv yog me ntsis qis dua kub-dip galvanizing.
Chrome lossis tooj liab plating: Hauv qee qhov chaw tshwj xeeb, cov hlua hlau yuav yog chrome lossis tooj liab plated los txhim kho nws cov kev tiv thaiv corrosion, uas yog tshwj xeeb tshaj yog zoo hauv kev ua tshuaj lom neeg los yog marine ib puag ncig.
4. Kev cia thiab tu kom zoo
Tsis txhob raug cov dej noo: Thaum siv cov hlua hlau, sim ua kom tsis txhob ya raws nws. Thaum khaws cia, cov hlua hlau yuav tsum tau khaws cia rau hauv qhov chaw qhuav kom tsis txhob muaj xeb.
Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua: Kev tshuaj xyuas cov hlua hlau tsis tu ncua, tshwj xeeb tshaj yog kuaj xyuas qhov hnav, corrosion lossis xaim tawg ntawm cov hlua hlau. Tsis txhob muaj teeb meem kev nyab xeeb tshwm sim los ntawm kev siv tsis raug los ntawm kev hloov lossis kho cov hlua hlau puas tsuaj rau lub sijhawm.
Tsis txhob overstretching: Tsis txhob tso cov hlua hlau nyob rau hauv lub xeev stretched rau lub sij hawm ntev. Overstretching yuav ua rau kev puas tsuaj rau cov qauv sab hauv ntawm cov hlua hlau, yog li cuam tshuam rau nws lub neej kev pabcuam. Tsis txhob thauj khoom ntau dhau thaum siv nws.
5. Siv txoj hlua khi txoj hlua qauv
Xaiv cov khoom siv hlua hlau zoo: Xaiv txoj hlua hlau raws li qhov chaw siv. Piv txwv li, cov hlua hluav taws xob tiv thaiv corrosion yog tsim rau siv nyob rau hauv tshuaj lom neeg ib puag ncig los yog offshore ua hauj lwm, thaum lub zog high-strength hlau ropes yog haum rau lifting cov cuab yeej uas yuav tsum tau tiv thaiv ntau dua loads.
Braiding qauv ntawm hlau hlua:
Cov kev sib txawv ntawm cov hlua khi (xws li txoj hlua peb-strand, xya-strand hlua, thiab lwm yam) muaj qhov sib txawv ntawm lub zog tensile, qaug zog tsis kam, hnav tsis kam, thiab lwm yam. Raws li kev xav tau tiag tiag, xaiv qhov tsim nyog braiding qauv ntawm cov hlua hlau.
6. Zam kev ua haujlwm tsis zoo
Zam cov kaum ntse ntse thiab kev sib txhuam:
Thaum siv cov hlua hlau, zam cov hlua hlau hla cov kaum ntse ntse lossis cov khoom ntse, vim qhov no yuav ua rau hnav lossis tawg ntawm cov hlua hlau. Sim kom tsis txhob muaj kev sib txhuam ntawm cov hlua hlau thiab qhov chaw tsis sib xws kom txo kev puas tsuaj.
