Txhawm rau tiv thaiv lub zog loj thiab cov kev ntxhov siab koom nrog hauv cov tshuab hydraulic, lub tog raj kheej pas nrig yuav tsum tau ua los ntawm cov khoom siv zoo thiab ruaj khov. Hlau yog cov khoom siv feem ntau siv rau hydraulic lub tog raj kheej pas nrig vim nws lub zog tshwj xeeb, toughness, thiab tsis kam hnav thiab corrosion. Txawm li cas los xij, tsis yog txhua hom hlau tsis haum rau lub hom phiaj no. Qee cov yam ntxwv thiab cov khoom tseem ceeb yog qhov tseem ceeb hauv kev txiav txim siab qib steel zoo tagnrho rau hydraulic kheej kheej rods.
Cov khoom ntawm Steel rau Hydraulic Lub tog raj kheej Rods
1. Lub zog: Hydraulic cylinders feem ntau ua haujlwm nyob rau hauv siab, thiab tus pas nrig yuav tsum muaj peev xwm tiv taus qhov siab no yam tsis muaj deformation. Cov hlau muaj lub zog tensile zoo heev, tso cai rau nws los tiv thaiv lub zog thaum ua haujlwm.
2. Toughness: Hydraulic systems undergo repetitive loading thiab unloading cycles, raug lub tog raj kheej pas nrig rau tej yam thiab qaug zog. Qib steel tawv tuaj yeem tiv taus cov khoom hnyav no yam tsis muaj kev tawg lossis ua nkig.
3. Hnav Resistance: Kev txav tsis tu ncua ntawm tus pas nrig thiab lub foob tuaj yeem ua rau muaj kev sib txhuam thiab hnav. Hlau nrog siab hnav tsis kam tuaj yeem tswj nws qhov kev ncaj ncees ntawm lub sijhawm ntev, txo qhov xav tau kev tu thiab hloov ntau zaus.
4. Corrosion Resistance: Hydraulic cylinders feem ntau siv nyob rau hauv ntau qhov chaw, nrog rau cov uas raug dej los yog tshuaj lom neeg. Corrosion-resistant steel pab tiv thaiv xeb thiab degradation, ua kom lub neej ntev ntawm lub tog raj kheej pas nrig.
5. Machinability: Kev tsim cov pas nrig lub tog raj kheej muaj cov txheej txheem machining, xws li tig, milling, thiab sib tsoo. Hlau uas yooj yim machinable tso cai rau cov khoom tsim tau zoo thiab qhov loj me.
6. Tus nqi siv tau: Cov qib steel xaiv yuav tsum sib npaug ntawm kev ua tau zoo thiab tus nqi. Thaum cov hlau muaj zog muaj zog tuaj yeem muab cov khoom zoo tshaj plaws, lawv tuaj yeem kim dua. Nws yog ib qho tseem ceeb uas yuav tau xaiv cov qib steel uas ua tau raws li daim ntawv thov uas yuav tsum tau ua yam tsis pub tshaj cov peev nyiaj.
Common Steel Qib rau Hydraulic Cylinder Rods
Ntau qib steel feem ntau siv los tsim cov hydraulic kheej kheej rods. Txhua qib muaj cov khoom tshwj xeeb uas ua rau nws haum rau daim ntawv thov no. Cov qib steel feem ntau siv xws li:
1. 1045 Medium Carbon Steel: Cov qib steel no paub txog nws lub zog zoo heev, kev cuam tshuam tsis zoo, thiab kev ua haujlwm zoo. Nws muaj cov ntsiab lus carbon ntawm 0.45% mus rau 0.55% thiab feem ntau yog kho cua sov los txhim kho nws cov khoom siv kho tshuab. 1045 steel yog ib qho yooj yim rau tshuab thiab muab kev hnav zoo, ua rau nws haum rau nruab nrab lub tog raj kheej hydraulic.
2. 4140 High-Tensile Steel: Nrog rau cov pa roj carbon ntau dua ntawm 0.38% rau 0.43% thiab ntxiv ntawm chromium thiab molybdenum, 4140 steel nthuav tawm kev txhim kho lub zog, toughness, thiab hardenability. Cov qib steel no feem ntau yog siv rau hauv lub tog raj kheej hydraulic hnyav uas xav tau kev ua haujlwm zoo, xws li cov khoom siv hauv kev tsim kho thiab cov tshuab mining.
3. 316 Stainless Steel: Nyob rau hauv daim ntawv thov qhov twg corrosion kuj yog qhov tseem ceeb tshaj plaws, 316 stainless hlau feem ntau xaiv. Nws muaj chromium, npib tsib xee, thiab molybdenum, muab kev tiv thaiv zoo rau corrosion los ntawm ya raws thiab tshuaj. Cov qib steel no yog tsim rau hydraulic thooj voos kheej kheej siv nyob rau hauv marine ib puag ncig los yog kev lag luam chaw nyob qhov twg yuav raug mob hnyav.
4. 17-4PH Stainless Steel: Cov nag lossis daus-tawv tawv stainless hlau muaj kev sib xyaw tshwj xeeb ntawm lub zog siab, tiv thaiv corrosion, thiab machinability. Nws muaj chromium, npib tsib xee, tooj liab, thiab lwm yam khoom me me. 17-4PH stainless hlau feem ntau yog siv rau hauv hydraulic thooj voos kheej kheej uas yuav tsum tau muaj zog tshwj xeeb thiab tsis kam hnav thiab corrosion, xws li cov siv hauv aerospace applications.
5. 52100 Bearing Steel: Nrog nws cov ntsiab lus siab carbon thiab hardenability zoo heev, 52100 bearing steel feem ntau siv nyob rau hauv hydraulic thooj voos kheej kheej uas yuav tsum tau tshwj xeeb hnav tsis kam. Cov qib steel no feem ntau pom muaj nyob rau hauv telescopic thooj voos kheej kheej thiab cov tshuab muaj kev lag luam uas tau txais cov khoom hnyav thiab kev txav mus tas li.
