Ib lub raj honed yog qhov siab - Precision cylindrical tivthaiv, uas tau undergone ib txheej txheem sab hauv cov txheej txheem hu ua honing. Cov txheej txheem no yog qhov tseem ceeb rau kev ua tiav cov qauv txheej txheem uas xav tau hauv kev xav tau cov kev thov hydraulic thiab pneumatic. Tsis zoo li tus qauv tubing, ib lub raj goned yog tus cwj pwm los ntawm nws qhov tshwj xeeb du sab hauv ua tiav, thiab zoo dua geometric cov khoom.
Cov txheej txheem tsim khoom lag luam cuam tshuam nrog cov cuab yeej honing, nruab nrog cov pob zeb txo qis, los ntawm kev ua kom lub raj. Qhov kev ua no tshem tawm cov tsis txaus ntseeg sab nraud thiab tsim kom meej, hla- hatched nto qauv. Qhov qauv tshwj xeeb no tsis yog tsuas yog smoothness; Nws yog ua haujlwm tau tsim los pab txhawb qhov tau zoo lubrication. Lub microscopic valleys nyob rau hauv tus qauv khaws roj, ua kom muaj kev sib xws ntawm lub raj ntawm lub raj sab hauv thiab cov ntsaws ruaj ruaj piston ntsaws ruaj ruaj. Qhov no drastically txo kev sib txhuam thiab hnav, nthuav dav lub neej kev ua haujlwm ntawm ob lub tog raj kheej raj thiab lub foob.
Qhov tseem ceeb ntawm qhov zoo ntawm kev siv cov leeg honed suav nrog:
* ** Qhov tshwj xeeb saum npoo tiav: ** Muab cov ntsaws ruaj ruaj rau cov ntsaws ruaj ruaj, txo kev sib txhuam thiab tiv thaiv kev pib foob tsis ua haujlwm thiab kua to.
* ** Txhim kho qhov tseeb geometric: ** ua kom muaj txiaj ntsig ncaj thiab kev sib tw ntawm lub bore, uas yog qhov tseem ceeb rau cov du, thiab kev ua haujlwm ywj pheej ntawm pistons.
* ** Kev sib xyaw ua ke lub neej: ** Kev sib xyaw ntawm cov hnav - Resistant nto thiab zoo tshaj plaws nce nce siab ntev dua rau lub tog raj kheej tag nrho.
* ** Kev ntseeg siab thiab ntseeg tau: ** Cov kev ncaj ncees zoo thiab ua kom muaj qhov tseem ceeb rau kev ua kom hnyav, ua rau hnyav {{duty {duty {
Raws li qhov tshwm sim, honed leeg yog qhov tsis tseem ceeb tiv thaiv nyob rau hauv hydraulic kheej pom thoob plaws ntau yam kev lag luam. Lawv tsim cov neeg tseem ceeb hauv cov khoom siv (xws li cov excavators thiab cov tshuab nqus dej), tshuab ua liaj ua teb, tshuab cov cuab yeej, thiab cov khoom siv tuav cov khoom siv. Hauv essence, txhua qhov chaw txhim khu, muaj zog, thiab muaj zog linear cov lus qhia ua qhov tseem ceeb, siab- kev ua lub hauv paus.
