Ntawm qhov ua tsis tiav ntawm hydraulic lub tog raj kheej, qhov teeb meem tshaj plaws yog qhov nyuaj rau kev txiav txim siab thaum cov khoom txawv teb chaws nkag mus rau hauv lub tog raj kheej hydraulic. Tom qab cov khoom txawv teb chaws nkag mus, yog tias lub foob nrog daim di ncauj tau teeb tsa rau sab nraud ntawm qhov zawv zawg qhov chaw ntawm lub piston, daim di ncauj ntawm lub foob tuaj yeem khawb cov khoom txawv teb chaws thaum lub sijhawm ua haujlwm, uas yog qhov zoo kom tsis txhob khawb. Txawm li cas los xij, ob qhov kawg ntawm lub piston nruab nrog O- lub nplhaib foob yog zawv zawg qhov chaw, thiab cov khoom txawv teb chaws yog sandwiched ntawm cov zawv zawg qhov chaw, uas yooj yim rau cov caws pliav.
Muaj ntau txoj hauv kev rau cov khoom txawv teb chaws nkag mus rau hauv lub tank.
① Foreign matter entering the cylinder
ib. Vim tias tsis muaj kev saib xyuas ntawm qhov chaw nres nkoj roj thaum lub sijhawm khaws cia, qhov xwm txheej ntawm kev tau txais cov khoom txawv teb chaws yuav tshwm sim txhua lub sijhawm, uas tsis tso cai kiag li. Thaum khaws cia, nws yuav tsum tau txhaj tshuaj tiv thaiv -cov roj xeb lossis cov roj ua haujlwm thiab ntsaws nws zoo.
b. Cov khoom txawv teb chaws nkag mus thaum lub tog raj kheej raug teeb tsa. Nyob rau hauv qhov chaw uas lub installation yog nqa tawm, cov xwm txheej tsis zoo, thiab cov khoom txawv teb chaws tuaj yeem nkag mus rau qhov tsis nco qab. Yog li ntawd, qhov chaw nyob ib puag ncig ntawm qhov chaw teeb tsa yuav tsum tau muab ntxuav, tshwj xeeb tshaj yog qhov chaw uas cov khoom yuav tsum tau muab ntxuav kom tsis txhob muaj av.
c. There are "burrs" on the parts, or insufficient scrubbing. There are often burrs left during drilling in the oil port on the cylinder head or in the buffer device. Pay attention to it and install it after the sand is removed.
② Foreign matter generated during operation
ib. Kev sib txhuam hlau hmoov los yog hlau filings tsim vim qhov nro ntawm qhov tsis plunger. Lub mating clearance ntawm lub buffer ntaus ntawv yog heev me me, thiab thaum lub lateral load ntawm tus pas nrig piston loj, nws yuav ua rau sintering. Cov hmoov txhuam hlau los yog cov khoom hlau uas tau poob vim yog sintering yuav nyob twj ywm hauv lub tog raj kheej.
b. Nplaim rau sab hauv ntawm lub tog raj kheej phab ntsa. Qhov zawv zawg saum npoo ntawm lub piston yog siab, ua rau sintering, yog li lub puab nto ntawm lub tog raj kheej yog nyem thiab tawg, thiab cov hlau tawg tau poob thiab tseem nyob hauv lub tog raj kheej, ua rau muaj caws pliav.
③ There are various cases of foreign matter entering from the pipeline.
ib. Tsis mob thaum tu. Thaum lub raj xa dej raug ntxuav tom qab kev teeb tsa, nws yuav tsum tsis txhob dhau los ntawm lub tog raj kheej lub tog raj kheej, thiab lub raj xa dej yuav tsum tau muab tso rau hauv pem hauv ntej ntawm qhov chaw nres nkoj roj ntawm lub tog raj kheej. lub ntsiab lus no tseem ceeb heev. Txwv tsis pub, cov khoom txawv teb chaws hauv lub raj xa dej yuav nkag mus rau hauv lub tog raj kheej. Thaum nws nkag mus, nws yuav nyuaj rau tshem tawm, thiab hloov nws yuav dhau los ua ib qho txawv teb chaws raug thauj mus rau hauv lub tog raj kheej. Tsis tas li ntawd, thaum tu, xav txog cov txheej txheem ntawm kev tshem tawm cov khoom txawv teb chaws uas tau nkag mus thaum lub sij hawm installation ntawm cov kav dej. Tsis tas li ntawd, rau corrosion nyob rau hauv cov yeeb nkab, cov txheej txheem xws li pickling yuav tsum tau ua ua ntej cov yeeb nkab yog ntsia, thiab cov xeb yuav tsum tau muab tshem tawm tag nrho.
b. Chips tsim thaum lub sij hawm ua yeeb nkab. Tom qab cov yeeb nkab tau raug txiav kom ntev, yuav tsum tsis muaj qhov seem seem thaum lub sijhawm ua haujlwm deburring ntawm ob qho kawg. Tsis tas li ntawd, kev tso cov kav hlau steel ze ntawm qhov chaw uas lub vuam kav dej ua haujlwm yog qhov ua rau kev sib xyaw ntawm vuam txawv teb chaws. Rau cov kav dej tso ze ntawm qhov chaw ua haujlwm vuam, lub nozzles yuav tsum tau muab kaw. Nws tseem yuav tsum tau muab sau tseg tias cov khoom haum yuav tsum tau ntim rau hauv cov plua plav -dawb workbench.
c. Txoj siv sealing nkag mus rau hauv lub tog raj kheej. Raws li ib qho yooj yim sealing khoom, PTFE yas sealing daim kab xev yog feem ntau siv nyob rau hauv installation thiab tshuaj xyuas. Yog hais tias txoj kev winding ntawm linear thiab daim kab xev sealing tsis raug, daim kab xev sealing yuav raug txiav tawm thiab nkag mus rau hauv lub tog raj kheej. Txoj hlua khi txoj hlua khi yuav tsis muaj qhov cuam tshuam rau qhov winding ntawm qhov zawv zawg qhov rooj, tab sis nws yuav ua rau lub check valve ntawm lub tog raj kheej tsis ua hauj lwm los yog ua rau lub valve tsis hloov mus rau qhov kawg; rau lub Circuit Court, nws yuav ua rau lub reversing valve, overflow Failure valve thiab siab txo valve ua.
Txoj kev kho ib txwm siv yog ua kom kho cov khoom siv kho mob tom qab disassembly ntawm cov khoom puas, lossis nqa cov txhuam plating lossis tag nrho cov khoom seem ntawm qhov chaw. Kev kho lub voj voog ntawm hydraulic lub tog raj kheej thaiv yog ntev thiab cov nqi kho yog siab.
