Cov ntaub ntawv rau cov thooj voos kheej kheej, cov pistons thiab cov pas nrig piston hauv lub tog raj kheej hydraulic
Jul 11, 2019
Cov thooj voos kheej kheej hydraulic yog ib qho ntawm cov cuab yeej tsis tseem ceeb hauv qhov chaw xa mus vim lawv cov qauv yooj yim, cov txheej txheem muaj zog yoog thiab muaj kuab paug ib puag ncig tsawg. Lawv siv dav hauv kev tsim kho tsheb, aerospace, tiv thaiv, hluav taws xob fais fab, plastics, machinery, metallurgy thiab Teeb Kev lag luam thiab lwm thaj chaw ntawm kev lag luam hauv teb chaws.
Hydraulic thooj voos kheej kheej yog mas tsim ntawm cov thooj voos kheej kheej, pistons, piston pas nrig thiab lwm cov ntu txuas. Txhua ntu tsis yog tsuas yog ua tib zoo tsim, tab sis txawm tias lawv cov ntaub ntawv tau xaiv tshwj xeeb kom tau raws li cov yam ntxwv ua haujlwm ntawm hydraulic lub tog raj kheej.
Ua ntej tshaj plaws, cov khoom siv ntawm hydraulic lub tog raj kheej thaiv, lub kaw lus ntawm lub tog raj kheej hydraulic yuav tsum tau txiav txim siab thaum xaiv. Yog tias nws yog hydraulic lub tog raj kheej hauv cov cuab yeej siv hauv tshuab, cov khoom siv ntawm lub tog raj kheej feem ntau yog ua los ntawm lub siab lub zog cam khwb cia hlau. Thaum lub siab siab tshaj 8MPa, nws raug pom zoo. Hloov mus rau cov yeeb nkab seamless steel.
Rau hydraulic lub tog raj kheej nruab rau hauv kev siv tshuab, 35 steel thiab 45 steel seamless steel tub yog siv los ua cov khoom siv kheej kheej hauv feem ntau. Thaum lub siab loj, 27SiMn seamless steel hlab los yog 45 steel forging tuaj yeem siv los kho lub siab.
Qhov thib ob, cov khoom siv ntawm lub piston nyob rau hauv hydraulic kheej kheej muaj qee qhov kev sib raug zoo nrog nws cov txheej txheem qauv. Feem ntau, feem ntau ntawm cov xaim xaim hluav taws xob yog ua los ntawm 35 steel thiab 45 steel; thiab cov khoom siv ntawm cov sib dhos piston yog grey cam khwb cia hlau, hnav-resistant cam khwb cia hlau, aluminium alloy, thiab lwm yam. Rau cov kev xav tau tshwj xeeb, tooj, tooj daj thiab nylon hnav lub tes tsho tuaj yeem muab tso rau sab nraud ntawm cov hlau piston dawb.
Hauv qhov hydraulic lub tog raj kheej, lub piston thiab piv piston pas nrig ua haujlwm ua ke, yog li ntawd cov khoom siv ntawm lub pas nrig piston zoo ib yam li piston, thiab feem ntau kuj 35 steel thiab 45 steel. Alloy cov ntaub ntawv xws li 55 steel lossis 40Cr tsuas yog siv thaum kev cuam tshuam kev co ntawm lub hydraulic kheej yog loj.
