Muaj ob yam tseem ceeb ntawm kev xau hauv hydraulic system ntawm engineering machinery, to ntawm lub foob ruaj thiab to ntawm lub foob txav. Cov dej ntws tawm ntawm cov foob pob txha feem ntau suav nrog hauv qab ntawm lub tog raj kheej thiab cov pob qij txha ntawm txhua lub yeeb nkab sib txuas, thiab lwm yam, thiab cov xau ntawm qhov txav txav feem ntau suav nrog cov pas nrig piston ntawm cov roj kheej kheej, ntau txoj kev valve stems thiab lwm yam. Roj to kuj tseem tuaj yeem muab faib ua sab nraud to thiab sab hauv to. External leakage feem ntau yog hais txog kev xau ntawm cov roj hydraulic los ntawm qhov system mus rau ib puag ncig. Internal to yog hais txog qhov sib txawv ntawm qhov siab thiab qis siab sab.Vim yog vim li cas xws li lub neej thiab tsis ua hauj lwm ntawm cov ntsaws ruaj ruaj, cov roj hydraulic ntws los ntawm lub siab-siab mus rau qis-siab sab hauv lub system.

Yog vim li cas cuam tshuam cov dej xau:

1) Tsim cov yam ntxwv:

(1) Kev xaiv cov ntsaws ruaj ruaj Qhov kev ntseeg siab ntawm hydraulic system nyob ntawm ntau yam Hais txog kev tsim cov hydraulic system seals thiab xaiv cov ntsaws ruaj ruaj, vim yog kev xaiv tsis tsim nyog ntawm sealing qauv hauv kev tsim thiab kev xaiv cov ntsaws ruaj ruaj uas tsis tsim nyog. ua tau raws li cov qauv, hom compatibility, load tej yam kev mob, thiab qhov kawg siab ntawm hydraulic roj thiab sealing cov ntaub ntawv tsis raug muab coj mus rau hauv tus account nyob rau hauv tsim. , ua hauj lwm ceev, hloov nyob rau hauv ambient kub, thiab lwm yam. Tag nrho cov no ncaj qha los yog indirectly ua rau kom cov hydraulic system sib txawv degrees. Tsis tas li ntawd, txij li ib puag ncig uas siv cov tshuab tsim kho muaj cov plua plav thiab impurities, cov plua plav pov thawj tsim nyog yuav tsum tau xaiv hauv kev tsim. , los tiv thaiv cov plua plav thiab lwm yam av los ntawm kev nkag mus rau hauv lub kaw lus kom ua puas lub foob thiab paug cov roj, yog li ua rau to.

(2) Lwm qhov laj thawj tsim: Qhov tseeb geometric thiab roughness ntawm qhov txav ntawm qhov chaw tsis muaj kev paub txaus hauv kev tsim, thiab lub zog ntawm cov khoom sib txuas tsis yog ntsuas hauv kev tsim. Nuclear, thiab lwm yam, uas yuav ua rau kom tawg thaum lub sijhawm ua haujlwm ntawm cov tshuab.

2) Kev tsim khoom thiab kev sib dhos

(1) Manufacturing yam: Tag nrho cov hydraulic Cheebtsam thiab sealing qhov chaw muaj nruj me ntsis tolerances, nto kho, nto tiav thiab geometric tolerances, thiab lwm yam. Yog hais tias qhov sib txawv ntawm qhov tsis kam lees thaum lub sijhawm tsim khoom, piv txwv li: lub piston vojvoog ntawm lub tog raj kheej, qhov tob lossis qhov dav ntawm qhov sib khi zawj, qhov loj ntawm lub qhov rau kev txhim kho lub nplhaib sealing tsis kam, lossis nws tawm. ntawm puag ncig vim muaj teeb meem ua, muaj burrs lossis kev nyuaj siab, chrome plating yog tev tawm, thiab lwm yam, lub foob yuav deformed, khawb, crushed los yog tsis compacted, ua rau nws poob nws sealing muaj nuj nqi.Ib feem nws tus kheej yuav muaj cov ntsiab lus to hauv lub cev, thiab cov dej xau yuav tshwm sim tom qab sib dhos lossis thaum siv.

(2) Cov khoom sib dhos: Kev ua haujlwm siab phem ntawm cov khoom siv hydraulic yuav tsum raug zam thaum sib dhos. Kev quab yuam ntau dhau yuav ua rau deformation ntawm qhov chaw, tshwj xeeb tshaj yog siv cov pas nrig tooj liab los tsoo lub tog raj kheej thaiv, sealing flange, thiab lwm yam; cov khoom yuav tsum tau ua tib zoo tshuaj xyuas ua ntej sib dhos, thiab cov khoom yuav tsum tau ua tib zoo tshuaj xyuas thaum sib dhos. Muab cov khoom tso rau hauv cov roj hydraulic me me thiab nias lawv maj mam. Siv cov roj av thaum ntxuav, tshwj xeeb tshaj yog cov khoom siv roj hmab xws li sealing rings, plua plav rings, thiab О-rings. Yog tias koj siv roj av, lawv yuav yooj yim rau lub hnub nyoog thiab poob lawv qhov qub elasticity, yog li poob lawv txoj haujlwm sealing. .

3) Roj paug thiab kev puas tsuaj rau qhov chaw

(1) Cov pa phem. Nyob rau hauv atmospheric siab, li ntawm 10% ntawm huab cua yuav yaj nyob rau hauv hydraulic roj. Nyob rau hauv lub siab ntawm hydraulic system, ntau cua yuav yaj nyob rau hauv cov roj. Cua los yog roj. Huab cua ua npuas hauv cov roj. Yog hais tias lub siab ntawm kev txhawb nqa hydraulic hloov pauv sai ntawm qhov siab thiab qis hauv lub sijhawm luv luv ntawm lub sijhawm ua haujlwm, cov npuas yuav tsim kom muaj qhov kub thiab txias ntawm sab-siab thiab tawg rau sab qis. Yog hais tias thaum muaj pits thiab puas nyob rau saum npoo ntawm lub Cheebtsam ntawm lub hydraulic system, cov roj hydraulic yuav maj mus rau saum npoo ntawm lub Cheebtsam ntawm kev kub ceev kom accelerate lub hnav ntawm lub nto, ua rau to.

(2) Particle contamination Hydraulic cylinders yog cov thawj coj tseem ceeb ntawm qee qhov engineering machinery hydraulic systems. Vim kev ua hauj lwm Thaum lub sij hawm tus txheej txheem, piston pas nrig yog raug thiab nyob rau hauv ncaj qha kev sib cuag nrog ib puag ncig. Txawm hais tias lub tes tsho qhia tau nruab nrog cov plua plav thiab cov ntsaws ruaj ruaj, cov plua plav thiab cov av yuav inevitably raug coj mus rau hauv hydraulic system, ua kom khawb thiab puas tsuaj rau cov ntsaws ruaj ruaj, piston pas nrig, thiab lwm yam. Hnav, yog li ua rau cov pa tawm, thiab cov pa phem yog ib qho ntawm ceev tshaj plaws ua rau kev puas tsuaj rau hydraulic Cheebtsam.

(3) Kev ua qias tuaj vim muaj kev cuam tshuam ntawm cov khoom xws li cov chaw ua haujlwm ntub dej, cov dej tuaj yeem nkag mus rau hauv hydraulic system, thiab cov dej yuav hnov ​​​​mob nrog cov roj hydraulic los ua cov kua qaub thiab cov sludge txo cov lubrication kev ua haujlwm ntawm cov roj hydraulic thiab ua kom lub cev hnyav. ntawm cov khoom. Cov dej kuj tseem tuaj yeem ua rau lub qia ntawm lub valve los lo, ua rau nws nyuaj rau kev khiav haujlwm ntawm lub valve, khawb lub foob, thiab ua rau kom tawg.

(4) Qhov kev puas tsuaj yog tshwm sim los ntawm cov roj tsis kam. Ua los ntawm cov roj hmab thiab lwm yam khoom siv, kev laus, kev tawg, kev puas tsuaj, thiab lwm yam vim kev siv lub sij hawm ntev yuav ua rau lub cev tsis zoo. Yog tias cov khoom raug puas tsuaj los ntawm kev sib tsoo thaum ua haujlwm, cov khoom sib khi yuav raug khawb, ua rau kom tawg. Kuv yuav ua li cas? Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Qhov Tseem Ceeb Ua rau cov dej xau ntawm hydraulic system ntawm kev tsim kho tshuab yog qhov tshwm sim ntawm kev cuam tshuam los ntawm ntau yam. Nrog rau cov cuab yeej technology thiab cov ntaub ntawv uas twb muaj lawm, nws yog ib qho nyuaj rau fundamentally tshem tawm cov to ntawm hydraulic system.

Tsuas yog los ntawm cov kev cuam tshuam saum toj no Pib los ntawm cov khoom xau ntawm cov hydraulic system, cov kev ntsuas tsim nyog yuav tsum tau ua kom txo qis cov dej ntws ntawm hydraulic system kom ntau li ntau tau. Hauv kev tsim thiab kev sib txuas ua ke, cov yam tseem ceeb uas cuam tshuam rau kev xau yuav tsum tau txiav txim siab tag nrho hauv kev tsim thiab kev ua tiav ntawm qhov sealing groove.Tsis tas li ntawd, kev xaiv cov ntsaws ruaj ruaj kuj tseem ceeb heev. Yog tias tsis ua tiav tag nrho cov kev cuam tshuam cuam tshuam ntawm kev xau thaum pib yuav ua rau kev poob qis hauv kev tsim khoom yav tom ntej. Xaiv txoj kev sib dhos thiab kho kom raug thiab kawm los ntawm kev paub dhau los. Piv txwv li, sim siv cov cuab yeej tshwj xeeb hauv kev sib dhos ntawm cov nplhaib sib khi, thiab Siv qee cov roj rau ntawm lub nplhaib sealing.

Nyob rau hauv cov nqe lus ntawm hydraulic roj pollution tswj, peb yuav tsum pib los ntawm lub hauv paus ntawm cov pa phem, ntxiv dag zog rau kev tswj cov pa phem qhov chaw, thiab coj zoo filtration ntsuas thiab tsis tu ncua kev ntsuam xyuas roj zoo. Txhawm rau kom txiav tawm cov khoom siv sab nraud (Dej, plua plav, cov khoom, thiab lwm yam) kev sib kis ntawm lub tog raj kheej hydraulic, qee qhov kev tiv thaiv tuaj yeem raug ntxiv. Nyob rau hauv luv luv, kev tiv thaiv thiab kev tswj ntawm qhov to yuav tsum tau ua kom tiav thiab kev txiav txim siab yuav ua tiav kom ua tau zoo.
