Valve sib tsoo suav nrog cov txheej txheem ntxuav thiab tshuaj xyuas, txheej txheem sib tsoo thiab tshuaj xyuas txheej txheem.

1. Cov txheej txheem ntxuav thiab tshuaj xyuas

Ntxuav lub sealing nto nyob rau hauv lub lauj kaub roj, siv kev tu tus neeg saib xyuas, thaum ntxuav qhov kev puas tsuaj ntawm sealing nto tshuaj xyuas.Micro-cracks uas nyuaj rau kev txiav txim los ntawm qhov muag liab qab tuaj yeem kuaj pom los ntawm txoj kev xim.

Tom qab ntxuav, xyuas lub sealing nto ntawm disc los yog lub rooj vag valve nrog lub rooj zaum, kos nrog liab thiab xaum.Kuaj Liab Liab, kos lub SEAL nto luam theej duab, foob nto foob;los yog nrog ib tug cwj mem nyob rau hauv lub disc thiab lub rooj sealing nto ntawm ob peb concentric lub voj voog, ces disc thiab lub rooj zaum kaw rotation, xyuas cov cwj mem Circle rub tawm, xyuas kom meej sealing nto yog kaw zoo.Yog tias lub foob tsis zoo, tus qauv phaj tuaj yeem siv los kuaj cov disc lossis rooj vag sealing nto thiab lub cev sealing nto, txiav txim siab qhov chaw ntawm kev sib tsoo.

2. Cov txheej txheem sib tsoo

Kev sib tsoo yog qhov tseem ceeb ntawm kev txiav yam tsis muaj tshuab dhos.Qhov tob ntawm pits lossis qhov me me ntawm lub taub hau valve lossis lub rooj zaum feem ntau tsawg dua 0.5 hli, uas tuaj yeem kho los ntawm kev sib tsoo.Cov txheej txheem sib tsoo yog muab faib ua ntxhib sib tsoo, nruab nrab sib tsoo thiab nplua sib tsoo.

Rough sib tsoo yog kom tshem tawm qhov sealing nto ntawm khawb, indentation, pitting thiab lwm yam tsis xws luag, kom lub sealing nto kom tau ib tug siab flatness thiab ib tug tej degree ntawm smoothness, rau lub sealing nto ntawm lub hauv paus.Rough sib tsoo siv lub taub hau los yog sib tsoo cov cuab yeej, siv coarse abrasive ntawv los yog coarse abrasive muab tshuaj txhuam, nws particle loj 80 #-280 #, coarse particle loj, txiav ntim, high efficiency, tab sis sib sib zog nqus txiav kab, sealing nto yog ntxhib.Yog li ntawd, kev sib tsoo ntxhib ntev npaum li lub taub hau lossis lub rooj zaum ntawm lub valve tuaj yeem raug tshem tawm kom du.

Kev sib tsoo nruab nrab yog txhawm rau tshem tawm qhov sealing nto ntawm coarse grain, ntxiv txhim kho lub sealing nto ntawm smoothness thiab smoothness.Siv cov ntawv xuab zeb zoo los yog cov hmoov sib tsoo zoo, qhov loj me yog 280 #-W5, qhov loj me yog qhov zoo, qhov txiav me me, uas yuav pab txo qhov roughness, tib lub sijhawm yuav tsum hloov cov khoom sib tsoo sib tsoo, sib tsoo. cuab yeej yuav tsum huv si.Tom qab kev sib tsoo nruab nrab, lub dav hlau tiv thaiv valve yuav tsum ci.Yog tias koj siv cov cwj mem hauv lub taub hau lub taub hau lossis lub rooj zaum los kos ob peb, lub taub hau valve lossis lub rooj zaum tiv thaiv lub teeb tig ntawm lub voj voog, cov xaum kab yuav tsum tau muab tshem tawm.

Kev sib tsoo zoo yog cov txheej txheem kawg ntawm kev sib tsoo valve, feem ntau yog los txhim kho lub sealing nto tiav.Kev sib tsoo zoo tuaj yeem siv w 5 lossis finer thiab roj, kerosene thiab lwm yam dilution, nrog lub taub hau valve tiv thaiv lub rooj zaum sib tsoo, tsis muaj kev ua yeeb yam, qhov no yog qhov tsim nyog rau sealing nto.Thaum sib tsoo lub voj voog dav dav txog 60-100, tom qab ntawd rov qab kev taw qhia txog 40-90, maj mam sib tsoo ib pliag, yuav tsum tau kuaj xyuas, kom polished ci, thiab hauv lub taub hau thiab lub rooj zaum tuaj yeem pom lub voj voog ntawm cov kab nyias nyias. Thaum cov xim mus txog dub thiab ci thiab dub thiab ci, grind maj mam ob peb zaug nrog cov roj cav dua, so nrog cov ntaub qhwv huv si.Tom qab sib tsoo, thiab tom qab ntawd tshem tawm lwm yam tsis xws luag, uas yog, yuav tsum tau sib sau ua ke sai li sai tau, thiaj li tsis ua kom puas lub taub hau zoo valve.

Kev sib tsoo, txawm hais tias ntxhib lossis zoo, yog ib txwm los ntawm kev nqa, nqis, kev sib hloov, rov ua dua, tapping, thim rov qab thiab lwm yam kev ua haujlwm sib xyaw ua ke.Nws lub hom phiaj yog kom tsis txhob muaj qhov abrasive rov ua dua, kom cov cuab yeej lapping thiab sealing nto kom tau txais kev sib tsoo zoo sib xws, txhim kho qhov smoothness thiab smoothness ntawm sealing nto.

3. Theem soj ntsuam

Nyob rau hauv cov txheej txheem sib tsoo yog ib txwm dhau los ntawm kev tshuaj xyuas theem, nws lub hom phiaj yog txhawm rau txhawm rau sib tsoo qhov xwm txheej txhua lub sijhawm, kom paub tseeb tias kev sib tsoo zoo ua tau raws li cov kev xav tau.Nws yuav tsum tau muab sau tseg tias sib txawv valve sib tsoo yuav tsum tau siv los hloov mus rau ntau yam kev sib tsoo nto sib tsoo cov cuab yeej los txhim kho kev ua tau zoo ntawm kev sib tsoo, kev sib tsoo kom zoo.

Valve kev sib tsoo yog ib qho kev ua haujlwm zoo heev, xav tau hauv kev xyaum ua kom muaj kev paub tas li, grope, txhim kho, qee zaum sib tsoo zoo heev, tab sis tom qab kev teeb tsa lossis xau ntawm chav, qhov no yog vim tias nyob rau hauv cov txheej txheem sib tsoo muaj kev xav ntawm kev sib tsoo ib feem Tsis txhob tuav lub sib tsoo pas nrig ntsug, askew, los yog lapping cuab tam loj lub kaum sab xis yuam kev tshwm sim.
