I. Cov yam tseem ceeb cuam tshuam rau lub neej
1. Khoom thiab Substrate Quality: Lub zog thiab kev kho cua sov lub xeev ntawm lub substrate ncaj qha cuam tshuam tag nrho durability. Piv txwv li, 40Cr los yog GCr15 bearing steel muaj zog tiv taus ntau dua li 45 # steel, ua rau nws tsim nyog rau ntev - lub sij hawm siab -load hauj lwm.
2. Plating Zoo thiab Thickness: Ib qho plating uas nyias dhau yog yooj yim hnav los ntawm, nthuav tawm cov substrate thiab ua rau corrosion; lub plating uas tuab heev ua rau muaj kev ntxhov siab sab hauv thiab ua rau tawg. Feem ntau, ib qho nyuaj chrome plating thickness ntawm 50-200 micrometers yog zoo tagnrho rau kev lag luam siv. Microcracks los yog pores nyob rau saum npoo yuav ua rau kom corrosion propagation thiab txo cov lifespan.
3. Kev ua haujlwm ib puag ncig:
Qhuav, huv ib puag ncig: Lub neej ntev tshaj plaws, tswj kev ua haujlwm ntev.
Cov av noo, acidic, alkaline, los yog ntsev tsuag ib puag ncig: Yog tias tsis xaiv stainless hlau substrate los yog kev tiv thaiv tsis txaus, lub plating tej zaum yuav corroded, lub substrate yuav xeb, ua rau tsis ua hauj lwm ntxov ntxov.
High - ib puag ncig kub: Tshaj 480 degree, chrome plating pib oxidize thiab discolor, cuam tshuam kev ruaj ntseg.
Load and Motion Modes: High-frequency reciprocating motion, impact loads, or off-centre loads can lead to localized stress concentration, accelerating wear and fatigue crack formation. Kev siv tsis raug ntawm cov khoom xws li piston rods nrog cov ntsaws ruaj ruaj tuaj yeem ua rau lawv qhov chaw puas vim muaj cua sov los yog kev sib txhuam qhuav.
Kev tu thiab kev saib xyuas: Kev tu tsis tu ncua, tsis txhob khawb los ntawm cov khoom tawv, thiab kev tuav lub lubrication tuaj yeem ua rau lub neej ntev. Tshwj xeeb tshaj yog rau cov khoom siv tsis yog-stainless steel, yuav tsum zam qhov chaw ntub dej ntev ntev; siv xeb-cov roj tiv thaiv yog tias tsim nyog.
II. Lifespan Reference nyob rau hauv cov ntawv thov Scenario:
1. Hydraulic System Piston Qws (45 # Hlau + Chrome Plating): Nyob rau hauv nruab nrab load thiab lubrication zoo, kev siv ib txwm muaj peev xwm ncav cuag 3-8 xyoo.
2. Heavy-Lub Luag Haujlwm Hydraulic Lub tog raj kheej hauv Engineering Machinery (40Cr + Thick Plating): Tom qab yob txoj kev, txheej txheej ua haujlwm txias yog tsim rau ntawm qhov chaw, txhim kho hnav tsis kam thiab ncua kev ua neej mus txog 5-10 xyoo.
3. Khoom noj khoom haus / Cov Khoom Siv Kho Mob (304 Stainless Hlau + Chrome Plating): Kev xeb heev-resistant; nquag tu yam tsis muaj tshuaj corrosion; lifespan feem ntau tshaj 8 xyoo. 4. Precision linear guides (GCr15 + daim iav polishing): Siv nyob rau hauv automated khoom, lawv ua hauj lwm smoothly nrog tsawg tsawg hnav thiab ib tug tsim lub neej feem ntau tshaj 10 xyoo.
⚠️ Yog tias muaj cov kab nrib pleb zoo, qhov chaw tev tawm, lossis muaj kev sib txhuam tsis sib haum nyob rau saum npoo, lub tshuab yuav tsum tau nres tam sim rau kev tshuaj xyuas kom tsis txhob muaj kev puas tsuaj ntxiv.
III. Kev ntsuas tseem ceeb txhawm rau txuas lub neej ua haujlwm
1. Ua ntej siv chrome- plated tuav uas tau dhau los ua yob, vim tias qhov seem seem compressive kev nyuaj siab ntawm lawv qhov chaw pab foob micro- tawg thiab ncua kev qaug zog tsis ua haujlwm.
2. Nyob rau hauv ib puag ncig corrosive, stainless hlau substrates (xws li 304/316) raug pom zoo, kom ntseeg tau ib tug ntom, tsis yog - ntxeem tau plating txheej.
3. Zam kom tsis txhob tawm ntawm - nruab nrab qhov chaw thau khoom thaum lub sij hawm teeb tsa, kom ntseeg tau tias lub tes tsho qhia tau zoo sib xws kom txo qis kev quab yuam.
4. Tsis tu ncua xyuas qhov xwm txheej ntawm cov ntsaws ruaj ruaj kom tsis txhob muaj plua plav thiab cov khoom nkag mus thiab ua rau khawb.
