Hauv kev kub siab-muaj xwm txheej (xws li cov tshuab hluav taws xob hydraulic, thiab cov pas nrig tob hau ntsej muag ntawm kev nyuaj siab, thiab cov xov xwm corrosive, thiab ntim tsis ua haujlwm. Chrome plated Piston Rods (Chrome-Plated Piston Rods) ua rau lawv cov high-hardness chrome plating, thiab precision saum kev kho.
1. Cov qauv kev ruaj ntseg nyob rau hauv cov kev nyuaj siab: kev sib npaug zoo meej ntawm lub zog thiab tawv
Kev siv siab dua (feem ntau ntau dua lossis sib npaug rau 31.5MPA) xav tau piston pas nrig tiv thaiv tau zoo heev. Boton siv 42crmo alloy quenched thiab tempered steel ua lub substrate. Tom qab quenching ntawm 860 qib + tempering ntawm 580 degree tau nce siab tshaj 3000 xyoo ntau dua 3 zaug siab dua 3 zaug ntau dua Q235). Qhov "tsim muaj zog" tsim muaj peev xwm tiv thaiv axial compression thiab kev ntxhov siab nyob rau hauv kev kub siab tshwm sim los ntawm substrate deformation. Lub chrome plating txheej (hardness hv {{}}}) ua haujlwm ntau dua li 90% thiab ua haujlwm ntev dua kev ua haujlwm ntev los ntawm kev ua haujlwm siab ntev ntawm cov txheej txheem siab.
2. Corrosion-resistant barrier: tiv thaiv kev nkag siab nruab nrab hauv qab lub siab
Cov roj muaj txiaj ntsig zoo tshaj plaws yog feem ntau nrog cov roj corrosive (xws li hydraulic roj muaj qhov nyuaj rau kev tawm tsam kev nkag mus txawm tias pleev xim. Boton Lub Chrome-plated Piston Quaj Qus cov teeb meem no teeb meem los ntawm ob-txheej tiv thaiv me ntsis
Dense chrome plating layer physical isolation: The trivalent chromium electroplating process is used to form a 8-15μm thick plating layer, and its porosity ( Less than or equal to 5%) is only 1/3 of that of the ordinary chrome plating layer, which can block the penetration path of corrosive media (such as Cl⁻) under high pressure. Hauv cov tshuaj ntsev ua ke nrog lub siab ntawm 20mpa, chrome plating txheej yuav tiv taus ntau tshaj li 1000 npaug ntawm cov pob zeb tsis muaj xeb yuav qhia pitter hauv tsuas yog 72 teev;
Electrochemical Kev Tiv Thaiv Kev Tiv Thaiv: Lub Tuamts electrode ntawm chromium ({{}}. 74v) yog qis dua li ntawm cov hlau ({2}}. 44v). Thaum txheej txheej plating yog ib nrab plhaw, lub chrome plating txheej yog corroded ua ntej raws li anode los tiv thaiv lub hauv paus steel los ntawm corrosion. Qhov no "tiv thaiv kev tiv thaiv" txuas ntxiv lub neej corrosion ntawm lub piston pas nrig los ntawm ntau tshaj 5 zaug.
III. Sealing Kev Ua Tau Zoo: Dual Txheej Txheem Ntawm Qhov Raug Nto thiab Kev Sib Txhuam
Kev sib khi ua tsis tiav ntawm cov kev siv siab feem ntau yog tshwm sim los ntawm kev tsis taus saum npoo ntawm piston pas nrig. Boton ua tiav ob qho tseem ceeb los ntawm daim iav polishing (ra tsawg dua lossis sib npaug}. 2μm) + Chrome plating cov kev sib txuam tswj:
Tsawg nqus cov coefficient: Kev txhuam coefficient ntawm lub chrome plating txheej ({}}}. 2) tsuas yog 1/2 ntawm qhov uas tsis tau kho cov hlau tsis tau. Thaum siv nrog cov ntsaws ruaj ruaj (xws li kauj ruam ntawm cov kauj ruam thiab cov reciprocating tsis tshua muaj kev phom sij los ntawm 5% ntawm cov khoom siv piston piston tsawg dua 0.5%;
Nto hardness sib xws: mem tes electroplating thev naus laus zis siv los tswj cov txheej txheem kev ntxhov siab thiab ua kom muaj kev sib tsoo saum npoo av haum rau lub sijhawm ntev. Kev siv tshuab cov neeg siv khoom ntsuas pom tias lub tog raj kheej hydraulic uas tsis muaj kev lom zem ntawm 35MPA, uas yog 3 zaug ntev dua lub neej ntawm lub neej piston piston piston.
4. Kev yoog rau cov kev ua haujlwm hnyav: kev tiv thaiv synergistic tawm tsam kev kub siab thiab corrosion
Hauv kev sib cav sib ceg
Thickened Chrome plating Txheej (20-25 μm): Los ntawm ib qib kev sib cav sib ceg, thiab muaj peev xwm tiv thaiv kev loj hlob siab nce ntxiv los ntawm 50%;
Tsis muaj cov khoom siv tshuab hluav taws xob plhaw plhaw ua kom muaj zog ntxiv los ntawm 50 zaug
Cov kev tseev kom muaj cov pas nrig piston yog qhov tseem ceeb txoj kev sib tw ntawm "lub zog, corrosion tsis kam, thiab sealing". Boton Muaj Cov Khoom Siv Co., Ltd. Lub Hlwb Hlwb Piston, los ntawm kev sib koom ua ke ntawm cov khoom siv Science, tab sis kuj ua tau kev tiv thaiv ib leeg ntawm "Matrix nthuav dav-kev tiv thaiv-saum npoo -. Xaiv Boton cov khoom txhais tau tias koj tsis tas yuav txhawj txog kev ua kom muaj zog ntawm txoj kev sib cais, thiab koj tsis tas yuav muaj kev txhawj xeeb txog kev sib cais, thiab koj tsis muaj kev txhawj xeeb ntev dua, kev ua haujlwm ntev ". Qhov no tsis yog xaiv ib feem xwb, tab sis kuj tau peev txheej hauv kev ntseeg tau ntawm tag nrho cov kev ntsuas siab.
