Kusvika zvikamu makumi mana kubva muzana zvechirimwa chemuriwo chinogona kurasika nekuda kwekunaka kwemamwe masupamaketi.Nepo muriwo wewonky ungave usiri iwo unonyanyo kufadza, une hutano hwakafanana sehuyerwa hwakakwana.

Kutakura kukuvadzwa kwepamusoro kunogona kutora nzira dzakawanda, kubva kuspall mumijaho, kupfeka kubva pakusashanda kwemafuta, ngura nekuda kwemakemikari ane hukasha kusvika kune emanyepo ekunyepa mamaki anokonzerwa nekuzunguzika kwakamira.Nepo kushushikana kwepamusoro kunogona kukonzera zviratidzo zvinonetsa senge kupisa kwakanyanya, kuwedzera ruzha mazinga, kuwedzera kuzunguzika kana kunyanyisa kufamba kweshaft, hazvisi zvese zvekunze zvinotakura zvinonongedza kukanganisa kushanda kwemuchina wemukati.

Corrosion chiitiko chinongoitika uye chimiro chakajairwa chekutakura kukuvadzwa kwepasi kunofanirwa kurwiswa nemamaneja emafuta ekumahombekombe uye gasi.Kune gumi emhando dzemhando dzekuora, asi kutakura ngura kazhinji inowira muzvikamu zviviri zvakafara - kunyorova kwehunyoro kana kukoromoka.Iyo yekutanga inzvimbo yakasarudzika, asi inogona kuoneka pane chero chikamu chekubereka, ichigadzira inotyisa oxide layer semhedzisiro yemakemikari reaction ine simbi pamusoro.

Semuenzaniso, mumigodhi yekumahombekombe, mabearings anowanzo kuoneswa hunyoro kana alkalinity yakapfava nekuda kwekusangana kwavo nemvura yegungwa.Kuora kwakapfava kunogona kuguma nemavara akareruka pamusoro, asi muzviitiko zvakakomba, zvinogona kutungamira mukukwenya pamusoro peberengi, zvichikonzera maflakes echinhu chine ngura kupinda mujaho.Nechikonzero ichi, ngura inowanzozivikanwa semuvengi wechisikigo wemabheya.

Corrosion haingovhundutsi pakuona;inogona zvakare kukanganisa zvakanyanya mari yebhizinesi.Zvinoenderana neongororo yeIMPACT yakaitwa naNACE International, sangano rinotungamirira pasi rose rokudzora ngura, zvave zvichifungidzirwa kuti 15-35 muzana yokuora kwegore negore ingadai yakaponeswa kudai miitiro yakakwana yokudzora ngura ikateverwa.Izvi zvakaenzana nemari inochengetwa iri pakati peUS$375 ne$875 bhiriyoni pagore pasi rose.

Muvengi?

Hazvibviri kufuratira kukosha kwemitengo yecorrosion, zvisinei kuramba kwecorrosion kunofanirwa kutariswa pamwe nezvimwe zvinodiwa zvekushandisa sekutakura hupenyu hurefu uye mutoro.

Chimbofunga izvi semuenzaniso.Muchina wekuchera unodiwa kuti ushande nemazvo asi unofanirwa kushandawo mumamiriro ezvinhu asingaregereri.Nekuda kwekunyanya nharaunda yemafuta uye gasi rigs, corrosion resistant bearings inokurudzirwa.Kana mainjiniya ekugadzira aizosarudza bhero risingadziviriri zvakanyanya rakagadzirwa kubva kupolyether ether ketone (PEEK), izvi zvinomisa kukora mumakwara ayo, asi kunyatsoita kwemuchina kwaizokanganiswa.Muchiitiko ichi, kusarudza simbi isina simbi yakakwenenzverwa ine kutenderera kwepamusoro uku uchibvumira kuora kwepamusoro kungave kuri nani.

Paunenge uchiongorora kukodzera uye kunaka kwemabhengi, zvakakosha kutarisa kunze kwekunaka kwekunze.Corrosion control ingori imwe chete inodiwa kuita, izvo zvisingakodzeri kuenzana nekushaya kuita zvakanaka kana kukanganisa kutakurika kwemukati.

Kuve nechokwadi chekuti michina yakakodzera inosarudzwa inhanho yekutanga - uye izvi zvakakosha kune ese makina akakura uye zvinhu zvidiki, senge mabheya.Sezvineiwo, mamaneja enzvimbo dzekumahombekombe vanogona kuyera dhizaini yavo uye vanogona kusarudza kurwisa ngura padanho rekugadzira.Heano maitiro matatu ekudzora corrosion yekufunga nezvayo:

A-Zvinhu sarudzo

Simbi isina tsvina ndiyo yakanyanya kujeka sarudzo yekudzivirira ngura uye inoshandiswa zvakanyanya muindasitiri yemafuta negasi.Iinewo zvimwe zvinobatsira zvinhu zvakadai sekugara uye kupisa kupisa.440 giredhi Stainless simbi mabearings ane kumira zvakanaka munzvimbo dzakanyorova uye anowanzoshandiswa mumashandisirwo akadai seindasitiri yechikafu nechinwiwa.Nekudaro, 440 giredhi Stainless simbi mabearings ane kushomeka kwekudzivirira kumvura yemunyu uye akawanda akasimba makemikari, saka kune dzakaoma nharaunda dzemahombekombe 316 simbi isina tsvina inogona kutariswa.Nekudaro, sezvo 316 simbi isina tsvina haigone kuomeswa nemafuta, 316 mabearings akakodzera chete kune yakaderera mutoro uye yakaderera kumhanya application.Kusaita ngura kwadzo kunonyanya kunaka kana paine mweya weokisijeni wakakwana saka mabearings aya anonyanya kushandiswa pamusoro penzira yemvura, mumvura yegungwa inoyerera kana panogezeswa mabearings mushure mekunyudzwa mumvura yegungwa.

Imwe sarudzo yezvinhu ndeye ceramic.Mabhengi eceramic akazara akagadzirwa kubva ku zirconia kana silicon nitride ane PEEK makeji anogona kupa kunyange akakwira mwero wekupokana nekuora uye anowanzoshandiswa akanyura mumvura.Saizvozvo, mabearings epurasitiki, ane 316 simbi isina tsvina kana mabhora egirazi, anopa kupikisa kwakanaka kwazvo pakuora.Izvi zvinowanzogadzirwa kubva kuacetal resin (POM) asi zvimwe zvinhu zvinowanikwa kune akasimba asidhi uye alkalis sePEEK, polytetrafluoroethylene (PTFE) uye polyvinylidene fluoride PVDF.Kufanana ne316 giredhi mabearings, aya anofanirwa kungoshandiswa mune yakaderera mutoro uye yakaderera chaiyo maapplication.

Imwe nhanho yezvombo zvinopesana nekuora, ndeye inodzivirira yakavhara.Chromium uye nickel plating inopa kumira kwakanaka kwekuora munzvimbo dzinotyisa zvakanyanya.Nekudaro, machira anozopedzisira aparadzana kubva pakubereka uye anoda kugara achigadziriswa.Iyi haisiriyo sarudzo inonyanya kushanda kune offshore application.

B-Mafuta

Lubricant inopa firimu rakatetepa pakati penzvimbo dzekusangana muberengi kuderedza kukweshera, kubvisa kupisa uye kurambidza ngura pamabhora nemujaho.Kushata kwepamusoro uye kunaka kwekuzora kwakakosha zvakanyanya kupesvedzera zvinhu zvekuti kushushikana kwepasi kuchaitika here kana kuti kwete.

Kusarudza iyo chaiyo lubricant zvinhu.Munharaunda umo kuora kwepamusoro kunogona kuitika kunze kwekutakura, haifaniri kubvumirwa kuitika mukati.SMB Bearings inogona kupa mabearings akavharwa ane magirosi asingapindi mvura ane corrosion inhibitors.Aya ekuzora anochengetedza mukati meiyo kutakura uye anogona kuenzaniswa kune chaiyo offshore application nharaunda.Yakazara Ceramic Bearings inonyanya kutsanangurwa pasina lubrication asi inogona kuzora negirisi isina mvura kwehupenyu hwakareba.

C-Zvisimbiso

Munzvimbo dzakaomarara, kudzivirira kusvibiswa kwakakosha zvakanyanya, saka kusarudza chisimbiso chekubata kwakanaka kuona kuti zvinosvibisa hazvipinde mukutakura.Kune michina inogona kuoneswa hunyoro, chisimbiso chekusangana chinopawo kuwedzera kwekudzivirira kwemvura.Izvi zvinomisa kugezwa kwegirisi kubva pakubereka, zvichibvumira kuti iite basa rayo mukuzora nekudzivirira mukati meiyo fani.Imwe sarudzo ndeye simbi shield asi izvi zvinopa zvakanyanya kuderedzwa dziviriro kubva mukunyorova.

Nekuongorora nharaunda yekushanda, inoda hupenyu hurefu uye mitoro inozoiswa kune iyo kutakura, iyo yakanakisa kutakura ingave yakazvininipisa 'wonky muriwo' uye kwete iyo inoramba ichitarisa aesthetically kufadza kwenguva refu.Nekutarisisa mamiriro akazara ekushanda kwezvakatipoteredza, mainjiniya edhizaini anogona kuyera kana kusarudza dhizaini yekudzora corrosion ndiyo inodhura zvakanyanya, kuwedzera hupenyu hwekutakura uye kusimudza mashandiro emuchina.
