Yuav ua li cas kho lub hydraulic kheej kheej piston pas nrig?

Tom qab lub piston pas nrig ntawm cov roj-kua boosting lub tog raj kheej yog strained thaum lub sij hawm ua hauj lwm, yog hais tias nws tsis ua hauj lwm nyob rau hauv lub sij hawm, nws yuav cuam tshuam rau kev siv ntawm cov khoom yam tsawg kawg nkaus, thiab nyob rau hauv mob hnyav, hydraulic lub tog raj kheej yuav tsis ua hauj lwm. Yog li peb kho nws li cas?
Cov khawb khawb yuav raug kho los ntawm kev sib tsoo hauv zos thiab polishing; Cov khawb hnyav dua yuav raug kho los ntawm kev sib tsoo thiab phau ntawv sib tsoo.
Tsim cov cim rub tawm: Tom qab cov roj-kua boosting lub tog raj kheej raug tshem tawm, nws tau pom tias ib qho ntawm cov piston rods ntawm lub tog raj kheej luffing tau hnyav heev, nrog 6 rub cov cim ntawm ib sab.
Lub ntsiab yog vim li cas rau lub piston qws strain yog hais tias tom qab lub plua plav nplhaib ua nkig thiab ntog tawm nyob rau hauv ib tug thaiv, nws tsis tsuas yog poob nws cov plua plav pov thawj, tab sis kuj accumulates ib tug ntau ntawm cov plua plav thiab cov ntawv xov xwm nyob rau hauv expansion sib koom ua ke, ua rau lub piston pas nrig. grind ncaj qha tawm tsam impurities, ua rau lub piston puas. Cov pas nrig tau ncab, thiab cov khawb khawb khawb cov roj hmab sealing tivthaiv ntawm lub tog raj kheej lub qhov ncauj, ua rau kom loj heev ntawm lub tog raj kheej hydraulic.
Kev kho kom zoo: Cov khoom muab tub lim thiab cov khoom siv hauv paus yuav tsum tau ua kom ruaj khov thiab ua haujlwm zoo; cov seasoning yuav tsum tau ruaj thiab yooj yim ua los ntawm tes; phau ntawv ua yuav tsum xyuas kom meej tias lub piston pas nrig txoj kab uas hla qhov yuam kev yog tsawg dua 0.06mm.
Tom qab kev tsom xam, nws tau txiav txim siab tias cov khoom siv siv yog J422 electrode. Vim tias acidic welding rods tsis hnov ​​​​tsw rau xeb, roj thiab noo noo, thiab tsis ua rau hydrogenation qhov; lawv muaj craftsmanship zoo thiab yooj yim rau kev khiav lag luam; cov welds tau tsim zoo nkauj; cov khoom muaj nruab nrab hardness thiab yog ib qho yooj yim mus ua tiav los ntawm tes; lub arc yog ruaj khov, kev nkag mus yog loj, thiab nws yog raws li nyob rau hauv cov ntaub ntawv ntawm lub hauv paus ntawm daim ntawv cog lus muaj zog.
Cov txheej txheem kho:
(1) Ntxuav qhov chaw yuav tsum tau welded ua ntej, thiab tom qab ntawd ncig cov cim rub nrog cov av ntub dej.
(2) Siv lub vuam pas nrig nrog txoj kab uas hla ntawm 2.5 hli, kho qhov tam sim no ntawm lub tshuab vuam mus rau 120A, thiab siv txoj kab ncaj nraim ntawm tus pas nrig txav txoj kev los ua vuam zoo.
(3) Tom qab tag nrho cov welding tiav lawm, ntxuav cov av nkos thiab slag, siv ib tug ntxhib ntxhib ntxhib los mos ntaub ntaub raws li ib ncig ntawm lub piston pas nrig thiab tawm ib tug machining pub ntawm 0 1-0.2 hli.
(4) Siv lub tog raj kheej nrog ib txoj kab uas hla sab nraud ntawm 185mm, ib txoj kab uas hla ntawm 125mm, thiab qhov ntev ntawm 150mm raws li tus tswv (txoj kab uas hla ntawm piston pas nrig yog 125mm), thiab pom nws raws li axis. Ib qho yog pwm ntxhib thiab lwm qhov yog pwm zoo.
(5) Siv ib txheej nyias ntawm cov roj stamping rau sab hauv phab ntsa ntawm cov pwm ntxhib, tom qab ntawd tso cov pwm ntxhib tawm tsam qhov yuav tsum tau kho ntawm tus pas nrig piston thiab khiav nws rov qab mus rau ntawm axis ob peb zaug, thiab tom qab ntawd siv. ib cov ntaub ntawv zoo los tshem tawm cov ntawv hnyav hnyav ntawm lub piston pas nrig. Ua ntaub ntawv nws tawm. Rov ua cov txheej txheem ua ntaub ntawv ua li no kom txog thaum cov nyiaj ua haujlwm ntawm 0 04-0.07mm sab laug.
(6) Tom qab ntawd siv lub 320-mesh xuab zeb bar dipped nyob rau hauv kerosene thiab phim cov precision pwm los zom cov piston pas nrig rau qhov luaj li cas.
(7) Thaum kawg, siv lub nraub qaum ntawm daim ntaub emery dipped hauv kerosene rau phau ntawv polishing. Tom qab ntsuas, qhov yuam kev siab tshaj plaws tsuas yog 0.03mm.
Tom qab kev kho cov roj-kua boosting lub tog raj kheej, tom qab ib thiab ib nrab xyoo ntawm kev siv, lub luffing hydraulic lub tog raj kheej yeej tsis leaked. Nyob rau tib lub sijhawm, tus pas nrig piston yog du thiab tsis muaj xeb.
