Ua-nws-koj tus kheej xeb tshem tawm ntawm lub tsheb

Lub cev ntawm lub tsheb thiab nws cov hauv qab yog ua los ntawm cov hlau, uas yuav raug corrosion. Yog tias koj niaj hnub siv cov tshuaj tiv thaiv corrosion thiab tsis muaj xeb rau ntawm lub cev, qhov no tsis yog qhov tseeb tias nws tsis nyob hauv qhov teeb meem - hauv qab lub log arches, ntawm qhov chaw pib, hauv qab tis.

Yuav ua li cas yog tias, txawm tias tag nrho koj cov kev siv zog, corrosion tseem tshwm sim?

Tshem tawm xeb thiab corrosion nrog tshuaj

Muaj ntau yam tshuaj los tiv thaiv corrosion.

Txoj kev yooj yim tshaj plaws yog siv cov khoom siv xeb, piv txwv "VSN-1".

Qhov no yog ib qho tshuaj zoo heev uas muaj phosphoric acid. Nws tsuas yog corrodes xeb thiab tom qab nws tseem muaj cov quav hniav uas tuaj yeem so nrog cov ntaub ntub dej los yog ntxuav tawm nrog dej ntws.

Tej yam yooj yim pej xeem txoj kev kuj siv, piv txwv li, ib tug sib tov ntawm paraffin, kwv yees li ib puas grams, ib liter ntawm kerosene. Tag nrho cov khoom no yog tov thiab sab laug rau ib hnub. Tom qab cov tshuaj tau npaj lawm, lawv tau kho nrog rau qhov chaw ntawm lub cev puas tsuaj los ntawm xeb thiab corrosion. Siv cov khoom siv nrog cov ntaub qhwv los yog daim txhuam cev mos thiab tawm hauv lub xeev no rau 10-12 teev. Tom qab ntawd tsuas yog tshem tawm cov slurry tshwm sim.

Ib qho kev kho mob kuj yog tsim los ntawm cov lard zoo tib yam los yog tsiaj rog, camphor roj thiab graphite roj. Tag nrho cov khoom xyaw no tau sib xyaw kom zoo, lawv raug tso cai rau brew thiab txias. Thiab ces tag nrho cov no yog siv rau saum npoo thiab nyob twj ywm rau ib hnub. Tom qab ua li no, raws li cov kws tshaj lij, tsis muaj ib qho kab ntawm xeb sab laug.

Tom qab cov xeb raug tshem tawm, qhov chaw yog machined, primed thiab pleev xim rau.

Mechanical txoj kev kom tshem tau cov xeb

Cov tshuaj muaj txiaj ntsig zoo, tau kawg, tab sis qee zaum lawv pab tsis tau. Piv txwv li, yog hais tias xeb yog tob tob, ces kev siv cov converters hem tias cov kua qaub tuaj yeem ua rau cov txheej nyias nyias ntawm cov hlau, thiab kerosene nrog paraffin yuav tsis muaj txiaj ntsig zoo.

Nyob rau hauv cov xwm txheej tsis zoo li no, txoj kev tsim nyog tshaj plaws yog sandblasting. Tab sis ua ntej koj pib ua, lub tsheb lub cev yuav tsum tau ntxuav kom huv si nrog tshuaj zawv plaub hau thiab qhuav kom zoo kom tag nrho cov kev puas tsuaj pom meej meej.

Sandblasting yog nqa tawm siv lub tshuab tshwj xeeb uas muab cua thiab xuab zeb nyob rau hauv siab. Grains ntawm xuab zeb khob tawm xeb thiab tsis ua mob rau cov hlau, uas yog, nws thickness tsis txo. Txhawm rau kom tsis txhob ua kom puas cov xim pleev xim rau hauv cov cheeb tsam uas tsis muaj kev cuam tshuam los ntawm corrosion, lawv tau muab tso rau hauv daim kab xev npog.

Sib tsoo kuj yog siv dav. Nws yog nqa tawm ob leeg nrog kev pab los ntawm tshwj xeeb grinders, grinders thiab xyaum nrog nozzles, thiab nrog kev pab los ntawm improvised txhais tau tias - hlau txhuam thiab sandpaper nrog txawv degrees ntawm graininess. Kev sib tsoo tsis yog txoj kev nyiam tshaj plaws, vim tias koj tshem tsis tau tsuas yog xeb nws tus kheej, tab sis kuj yog txheej saum toj kawg nkaus ntawm cov hlau.

Yuav ua li cas tshem tawm xeb nrog koj tus kheej txhais tes?

Yog li, yog tias koj pom tias corrosion tsis meej "noj" lub cev ntawm koj lub tsheb, koj yuav tsum tau ua sai sai. Txawm hais tias koj xaiv txoj kev twg los tshem tawm, koj yuav tsum ua txhua yam kom zoo zoo. Yog tias koj noj cov tshuaj txhuam hniav, ces nco ntsoov tias lawv muaj cov kua qaub uas muaj zog, yog li ua txhua yam kev ceev faj. Thaum ua hauj lwm nrog lub grinder los yog grinder, hnav lub tshuab ua pa kom tsis txhob nqus cov hmoov av, kua roj vanish thiab xeb.

Nco ntsoov hnav tsom iav tiv thaiv.

Thaum cov xeb raug tshem tawm, qhov chaw ntxuav yuav tsum tau muab tso rau. Tos kom txog thaum lub putty dries, tshem tawm cov seem nrog sandpaper los yog ib tug grinder nrog ib tug "zero" nozzle. Ib qho primer yog siv rau sab saum toj ntawm putty, thiab painting twb nyob rau ntawm nws. Xaiv qhov ntxoov ntxoo zoo tsis yog ib txoj haujlwm yooj yim, yog li xyuas ua ntej seb cov xim sib phim, txwv tsis pub, tsis muaj xeb, koj yuav tau txais ib qho xim uas yuav sawv tawm tsam keeb kwm yav dhau ntawm lub Hoobkas xim.

Yog tias xeb tshwm rau hauv qab, ces koj tuaj yeem siv ntau yam tshuaj tiv thaiv corrosion uas niaj hnub siv thiab tiv thaiv hauv qab ntawm lub tshuab. Tsis txhob hnov ​​​​qab txog polishing lub cev thiab ua qhov teeb meem.

Video nrog cov lus qhia tiag tiag rau kev tshem tawm thiab tiv thaiv xeb.

Nyob rau hauv tib lub vis dis aus koj yuav kawm yuav ua li cas kom tshem tawm xeb ntawm lub cev hauv txoj kev electro-chemical.

Los ntawm txoj kev, lub npe nrov cola yuav yog tus pab zoo rau kev tshem tawm xeb 🙂
