Kev tu vaj tse niaj hnub ntawm cov ntxhua khaub ncaws: Tiv thaiv kev tswj kom txuas ntxiv kev pab cuam lub neej

Cov tshuab ntxhua khaub ncaws, raws li qhov tseem ceeb ntawm cov khoom siv sib txuas hauv cov tshuab sib txuas, ua haujlwm kom faib cov siab, tiv thaiv cov khoom ua haujlwm, txhim kho kev ntxhov siab, thiab tiv thaiv kom tsis txhob xoob.Txawm tias lawv qhov me me, lawv ncaj qha cuam tshuam rau kev ntseeg tau thiab kav ntev ntawm kev sib txuas. Thaum lub sijhawm ua haujlwm txhua hnub, cov tshuab ntxhua khaub ncaws raug cuam tshuam rau kev ua haujlwm tsis zoo vim yog ib puag ncig, kev hloov pauv, thiab kev sib dhos zoo. Yog li ntawd, tsim kom muaj kev tshawb fawb niaj hnub saib xyuas yog qhov tseem ceeb rau kev tswj hwm lawv lub neej kev pab cuam thiab tiv thaiv kev ua tsis tiav tam sim ntawd.

Lub hauv paus tseem ceeb ntawm kev saib xyuas niaj hnub yog kev tshuaj xyuas tsis tu ncua thiab kev ntsuas tus mob. Rau cov khoom siv tseem ceeb thiab kev sib txuas ntawm cov qauv, yuav tsum tau tsim ib qho kev tshuaj ntsuam xyuas ib ntus, tsom rau kev soj ntsuam cov tshuab ntxhua khaub ncaws kom deformation, tawg, hnav, corrosion, los yog txheej txheej txheej. Yog tias cov tshuab ntxhua khaub ncaws zoo tib yam qhia pom pom tseeb lossis thinning, nws qhia tau tias lawv tsis tuaj yeem faib cov khoom lag luam thiab yuav tsum tau hloov tam sim. Yog hais tias lub caij nplooj ntoos hlav ntxhua khaub ncaws poob lawv elasticity los yog tawg, lawv cov kev tiv thaiv -loosing muaj nuj nqi ua tsis tau tejyam. Toothed los yog anti-loosing washers nrog hnyav hnyav los yog passivated hniav vim corrosion kuj yuav tsum tau hloov. Kev tshuaj xyuas yuav tsum tau ua ke nrog torque retesting. Yog tias pom qhov txo qis ntawm qhov txawv txav, qhov xwm txheej ntawm lub gasket yuav tsum raug soj ntsuam raws li qhov ua tau.

Kev tu thiab tu yog qhov tseem ceeb rau kev ua haujlwm ntawm gasket. Hauv kev sib dhos lossis kev ua haujlwm ib puag ncig, plua plav, roj, hlau shavings, thiab cov tshuaj lom neeg tau yooj yim ua raws li lub gasket nto, cuam tshuam tsis tsuas yog cov coefficient ntawm kev sib txhuam, tab sis kuj tseem muaj peev xwm ua kom muaj zog corrosion lossis ua rau cov tshuaj tiv thaiv electrochemical. Thaum lub sij hawm tu, cov kuab tshuaj uas tsim nyog (xws li anhydrous ethanol los yog cov tshuaj detergents) yuav tsum tau siv los tshem tawm cov av, tsis txhob siv cov kua qaub lossis alkalis kom tsis txhob muaj kev puas tsuaj rau cov khoom siv gasket lossis txheej tiv thaiv saum npoo. Rau cov hlau tsis muaj steel lossis tshwj xeeb alloy gaskets, lawv yuav tsum tau qhuav tam sim ntawd tom qab ntxuav kom tsis txhob muaj dej seem ntawm inducing pitting corrosion.

Kev saib xyuas hauv ib puag ncig corrosive yuav tsum tau saib xyuas ntau dua. Rau cov gaskets raug dej noo, tshuaj tsuag ntsev, lossis tshuaj lom neeg, ntxiv rau kev tshuaj xyuas qhov muag, kev ntsuas cov yeeb yaj kiab yuav tsum tau ua ib ntus (rau cov txheej txheem xws li galvanized thiab Dacromet). Yog tias cov txheej txheem tiv thaiv thins mus rau qhov tseem ceeb, rov- kev tiv thaiv lossis hloov yuav tsum tau npaj. Rau gaskets nyob rau hauv qhib- huab cua los yog offshore chaw, nws raug nquahu kom kho cov txheej txheem tiv thaiv thaum lub qhov rais tu thiab siv los tiv thaiv- xeb roj raws li qhov tsim nyog txhawm rau txhawm rau tiv thaiv huab cua.

Kev txheeb xyuas qhov zoo ntawm kev sib dhos kuj yog ib qho tseem ceeb ntawm kev saib xyuas gasket. Thaum hloov lossis rov nruab cov tshuab ntxhua khaub ncaws, xyuas kom meej tias lawv phim cov ntsiab lus ntawm cov bolts thiab txiv ntseej, raug muab tso rau hauv, thiab haum snugly kom tsis txhob muaj kev ntxhov siab los ntawm misalignment. Rau kev taw qhia lossis sab hauv / sab nraud sib txawv los tiv thaiv -loosing washers, nruab lawv raws li cov lus qhia kom ua tiav lawv txoj haujlwm tsim. Thaum lub sij hawm zawm, ua raws li lub zog torque thiab ib ntus kom tsis txhob dhau - zawm uas tuaj yeem tsoo lub tshuab ntxhua khaub ncaws lossis hauv qab - zawm uas tuaj yeem tawm qhov khoob.

Cov ntaub ntawv khaws cia thiab traceability pab txhawb kev txhim kho txuas ntxiv hauv kev saib xyuas gasket. Tsim kom muaj lub cav hloov gasket, ceeb toom hnub teeb tsa, kev ua haujlwm, cov ntaub ntawv xeem, thiab cov neeg ua haujlwm tu, muab lub hauv paus rau kev ntsuas lub neej tom ntej thiab kev ntsuas tsis ua haujlwm. Rau cov nodes uas zoo sib xws kev puas tsuaj rov tshwm sim, kev txhim kho kev ntsuas yuav tsum tau tsim nyob rau hauv cov cheeb tsam xws li kev tswj ib puag ncig, kev xaiv gasket optimization, los yog kev tiv thaiv kev hloov kho.

Hauv cov ntsiab lus, kev tu lub gasket niaj hnub yog ib txoj haujlwm ua ke nrog kev tshuaj xyuas, tu, kev tiv thaiv, thiab kev tswj xyuas kev sib dhos. Los ntawm kev tsim kho thiab kev saib xyuas ib ntus, kev pheej hmoo ntawm kev sib txuas xoob lossis cov khoom ua haujlwm puas tsuaj los ntawm gasket tsis ua haujlwm tuaj yeem txo qis, muab kev lav zoo rau kev nyab xeeb thiab ruaj khov ntawm cov khoom siv thiab cov qauv.
