Qib Steel
Lub tog raj kheej hydraulic piston pas nrig feem ntau yog tsim los ntawm qib siab - zoo carbon steel qib xws li AISI 1045 lossis zoo sib xws. Qib no muaj qhov sib npaug ntawm lub zog, hardness, thiab machinability, ua rau nws zoo tagnrho rau cov ntawv thov.
Daim ntawv thov
Lub tog raj kheej hydraulic piston pas nrig yog ib qho tseem ceeb ntawm cov tshuab hydraulic siv nyob rau hauv ntau yam kev lag luam thiab cov tshuab txawb. Nws lub luag haujlwm tseem ceeb yog hloov cov quab yuam los ntawm lub tog raj kheej hydraulic mus rau lub tshuab cov khoom, ua kom muaj zog thiab ua haujlwm. Nws pom cov ntawv thov hauv hydraulic thooj voos kheej kheej siv hauv cov khoom siv, kev ua liaj ua teb, cov khoom siv tuav, thiab cov khoom siv tsheb.
Cov qhab nia xaiv tau
Thaum AISI 1045 yog cov qib steel feem ntau siv rau hydraulic lub tog raj kheej piston rods, muaj lwm qib muaj nyob ntawm cov kev xav tau tshwj xeeb. Qee qhov kev xaiv muaj xws li AISI 4140, AISI 4340, thiab AISI 52100. Cov kev xaiv no muaj cov khoom sib txawv xws li lub zog siab dua, zoo dua corrosion, lossis txhim kho hnav tsis kam, ua rau cov kev xav tau sib txawv.
