Lub Tog Raj Kheej Hydraulic Muaj Zog Siab - Ck45/S45C Hlau - Hlau Chrome Plated
Lub zog hydraulic no muaj zog heev Lub tog raj kheej Piston Qws yog tsim los rau kev ua kom muaj zog thiab lub neej ntev hauv cov chaw ua haujlwm nyuaj. Tsim los ntawm cov hlau Ck45 zoo tshaj plaws lossis sib npaug S45C nruab nrab carbon hlau, cov khoom siv tseem ceeb muab kev sib npaug zoo ntawm lub zog thiab kev tawv. Cov khoom siv dhau los ntawm kev kho cua sov Quenching thiab Tempering (Q&T) kom raug, uas ua kom nws cov qauv me me zoo tshaj plaws thoob plaws hauv seem hla. Qhov no ua rau muaj lub zog tensile siab thiab muaj peev xwm thauj khoom zoo dua, tiv taus kev khoov thiab kev ntxhov siab torsional hauv qab cov khoom hnyav.
Qhov saum npoo ntawm tus pas nrig yog ua tiav nrog cov khoom siv chrome nyuaj uas muaj zog heev. Cov txheej no tsis yog tsuas yog ib txheej zoo nkauj xwb; nws yog ib qho kev thaiv kev ua haujlwm uas ua rau qhov nyuaj ntawm qhov chaw nce mus txog li 65-70 HRC. Qhov kev tawv no muab kev tiv thaiv zoo rau kev hnav abrasive, uas yog ib qho ua rau tsis ua haujlwm hauv cov ntawv thov uas muaj cov xuab zeb, cov pa phem, lossis kev sib hloov tas li. Ntxiv mus, cov txheej chrome muab kev tiv thaiv corrosion zoo heev, tiv thaiv cov hlau hauv qab los ntawm xeb thiab pitting hauv cov huab cua noo lossis me ntsis corrosive, yog li ua rau lub neej ua haujlwm ntawm ob qho tib si pas nrig thiab lub tog raj kheej foob ntev dua.
Yuav kom ntseeg tau tias muaj kev ua tau zoo tshaj plaws, txhua lub pas nrig piston yog qhov tseeb kom ua tiav qhov chaw zoo li daim iav nrog kev kam rau siab heev. Qhov roughness ntawm qhov chaw qis (feem ntau Ra ≤ 0.2 μm) yog qhov tseem ceeb rau kev txo qis kev sib txhuam thiab tiv thaiv kev hnav ua ntej ntawm cov foob pob hluav taws xob, uas ua rau tshem tawm cov kua dej xau thiab tswj kev ua haujlwm ntawm lub kaw lus hydraulic. Peb qhov kev tswj hwm zoo suav nrog kev tshuaj xyuas cov khoom sib nqus kom pom cov qhov tsis zoo ntawm qhov chaw lossis hauv qab, lav qhov kev ua tiav ntawm cov qauv.
Cov pas nrig no yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv hnyav, suav nrog cov tshuab siv hauv kev tsim kho (piv txwv li, excavators, bulldozers), cov tshuab nias rau kev lag luam, cov khoom siv hauv kev khawb av, thiab cov tshuab ua liaj ua teb. Lawv tau tsim los xa cov haujlwm txhim khu kev qha, tsis tas yuav saib xyuas, txo lub sijhawm tsis ua haujlwm thiab tag nrho cov nqi ntawm kev muaj. Los ntawm kev koom ua ke cov khoom siv zoo tshaj plaws nrog cov txheej txheem tsim khoom siab heev, cov pas nrig piston no sawv cev rau qhov kev hloov kho tseem ceeb rau txhua qhov kev ua haujlwm siab hydraulic uas xav tau kev ntseeg siab tsis tu ncua.
