Srb Honed Hydraulic Lub tog raj kheej Tube
Hauv kev nrhiav kev ua tau zoo tshaj plaws thiab kev ua haujlwm zoo hauv cov tshuab hydraulic, Skived thiab Roller Burnished (SRB) honed tube sawv cev rau kev txhim kho thev naus laus zis tseem ceeb tshaj li cov txheej txheem honing. SRB Hydraulic Lub tog raj kheej Tube yog tsim los muab qhov tsis sib xws hauv qhov chaw tiav thiab geometric precision, ua rau nws qhov kev xaiv zoo tshaj rau kev thov, siab - daim ntawv thov.
Hauj lwm lawm
Hauv kev nrhiav kev ua tau zoo tshaj plaws thiab kev ua haujlwm zoo hauv cov tshuab hydraulic, Skived thiab Roller Burnished (SRB) honed tube sawv cev rau kev txhim kho thev naus laus zis tseem ceeb tshaj li cov txheej txheem honing. SRB Hydraulic Lub tog raj kheej Tube yog tsim los muab qhov tsis sib xws hauv qhov chaw tiav thiab geometric precision, ua rau nws qhov kev xaiv zoo tshaj rau kev thov, siab - daim ntawv thov.
Lo lus "SRB" piav qhia txog ob qho kev sib tw -theem kev tsim khoom. Thawj theem yog Skiving (los yog Skiving), qhov twg ib qho - taw tes txiav cov cuab yeej precisely tshuab rau sab hauv ntawm lub seamless steel raj. Cov kauj ruam no yog tsim kom muaj qhov kawg sab hauv txoj kab uas hla thaum tib lub sijhawm kom ntseeg tau qhov ncaj ncaj (feem ntau zoo dua 0.5 hli / 1000mm) thiab kho txhua qhov sib txawv ntawm geometric. Nws tsim lub hauv paus zoo meej rau theem tseem ceeb tom ntej.
Qhov thib ob theem yog Roller Burnishing. Tam sim ntawd tom qab skiving, lub hardened, heev polished rau cov menyuam cov cuab yeej yog hydraulically los yog mechanically yuam tawm tsam sab hauv. Qhov txias no - txheej txheem ua haujlwm micro- qhov loj me ntawm qhov chaw los ntawm compressing lub ncov ntawm cov cuab yeej skiving rau hauv hav. Qhov kev txiav txim no ua tiav ob lub hom phiaj tseem ceeb: nws tsim ib qho zoo kawg nkaus, daim iav -zoo li tag nrog qhov roughness feem ntau qis li Ra 0.1 - 0.4 μm, thiab nws induces sib sib zog nqus compressive residual stresses ntawm txheej txheej. Cov kev ntxhov siab no ua haujlwm- ua kom cov khoom siv, ua kom nws lub zog qaug zog thiab tsis kam hnav thiab corrosion.
Cov txiaj ntsig ntawm cov txheej txheem no yog qhov tob. Lub ultra- du tiav drastic replicates kev sib txhuam ntawm lub raj phab ntsa thiab cov piston seals, ua rau kom muaj zog system efficiency, txo tshav kub, thiab ua rau lub neej ntev sealing. Kev txhim kho saum npoo kev ncaj ncees thiab compressive stresses txhim khu lub raj muaj peev xwm tiv taus siab cyclic pressures, tiv thaiv kev qaug zog tawg thiab ua rau tag nrho cov kev pab cuam lub neej thiab kev ntseeg siab ntawm lub tog raj kheej hydraulic.
Tsim los ntawm siab- zoo steels zoo li ST52, E355, CK45, los yog 4130/4140 alloys rau cov qauv xws li DIN 2391, thiab muaj nyob rau hauv ib tug ntau yam ntawm txoj kab uas hla thiab ntev, SRB raj yog cov nyiam nyob rau hauv cov kev siv tseem ceeb. Lawv yog qhov tseem ceeb hauv cov khoom hnyav- lub luag haujlwm siv tshuab, siab - cov tshuab txhaj tshuaj molding, kev siv tshuab hluav taws xob, thiab cov khoom siv txawb uas tsis muaj kev xaiv.
Hauv cov ntsiab lus, SRB Honed Tube yog ntau tshaj li lub tog raj kheej chim; nws yog qhov tshwm sim ntawm precision engineering aimed ntawm maximizing kev ua tau zoo. Los ntawm kev sib txuas cov duab geometric raug nrog lub ntsej muag zoo tshaj plaws, nws muab cov kev ntseeg siab tsis sib haum xeeb, kev ua haujlwm zoo, thiab kev ua haujlwm ntev, kom ntseeg tau tias cov tshuab hydraulic ua haujlwm ntawm lawv qhov zoo tshaj plaws.
