Hauv ntiaj teb ntawm cov li qub kev lag luam, cov li qub npauj npaim uas muaj hlau sawv tawm ua qhov kev xaiv txhim khu kev qha thiab ua haujlwm tau zoo rau kev tswj cov dej ntws ntawm ntau yam khoom. Hom li qub no yog tsim los kom tiv taus qhov kub siab, cov khoom siv corrosive, thiab cov khoom siv abrasive, ua rau nws yog qhov kev xaiv nrov hauv kev lag luam xws li roj thiab roj av, kev ua tshuaj lom neeg, thiab kev tsim hluav taws xob. Hauv cov blog no peb yuav tshawb nrhiav cov txiaj ntsig ntawm kev siv lub li qub npauj npaim uas muaj hlau thiab vim li cas nws thiaj yog thawj qhov kev xaiv rau ntau daim ntawv thov.

1. Kev ruaj khov thiab lub neej ntev
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov hlau zaum npauj npaim valve yog lawv lub zog thiab lub neej ntev. Tsis zoo li cov rooj zaum mos, uas yooj yim hnav thaum raug rau qhov kub thiab txias siab thiab cov khoom siv abrasive, cov rooj zaum hlau valve tau tsim los tiv taus cov xwm txheej ua haujlwm hnyav. Cov rooj zaum hlau muab lub foob nruj thiab tiv taus xeb, ua kom lub neej ua haujlwm ntev dua thiab txo qhov yuav tsum tau saib xyuas. Qhov no ua rau cov hlau zaum npauj npaim valve yog qhov kev daws teeb meem pheej yig rau cov lag luam uas xav tau kev ua haujlwm ntawm lub valve txhim khu kev qha thiab kav ntev.

2. Cov ntawv thov kub siab
Cov qhov rooj hlau uas zaum ntawm lub qhov rooj npauj npaim yog qhov zoo tagnrho rau kev siv qhov kub siab uas cov qhov rooj mos mos yuav tsis ua haujlwm. Cov rooj zaum hlau tuaj yeem tiv taus qhov kub siab heev yam tsis muaj kev cuam tshuam rau lawv lub peev xwm kaw, ua rau lawv zoo tagnrho rau cov txheej txheem uas muaj cov pa kub, cov pa dej thiab cov khoom siv yaj. Lub peev xwm no los tswj qhov kub siab ua rau cov qhov rooj npauj npaim uas zaum ntawm lub qhov rooj hlau yog ib qho khoom muaj nqis hauv kev lag luam xws li kev tsim hluav taws xob, petrochemicals thiab metallurgy, qhov twg kev tiv taus cua sov yog qhov tseem ceeb.

3. Kev tiv thaiv xeb
Hauv cov lag luam uas muaj cov khoom siv corrosive, xws li kev ua tshuaj lom neeg thiab kev kho dej khib nyiab, kev tiv thaiv corrosion yog qhov tseem ceeb hauv kev xaiv lub valve. Cov npauj npaim hlau uas muaj cov hlau zaum yog ua los ntawm cov ntaub ntawv xws li hlau tsis xeb, hlau duplex thiab lwm yam alloys uas tiv thaiv corrosion thiab tsim nyog rau kev tswj cov tshuaj corrosive thiab cov kua qaub. Cov rooj zaum hlau muab cov khoom tiv thaiv tiv thaiv corrosion, ua kom ntseeg tau tias lub valve muaj kev ncaj ncees thiab tiv thaiv kev xau lossis kev ua tsis tiav hauv cov chaw corrosive.

4. Hnav tsis kam
Rau cov ntawv thov uas muaj cov khoom siv abrasive, xws li kev khawb av, pulp thiab ntawv, thiab kev tuav slurry, lub peev xwm los tiv taus kev hnav thiab kev yaig yog qhov tseem ceeb. Cov hlau zaum npauj npaim valves tau tsim los tiv taus kev hnav thiab tswj lawv cov kev ua haujlwm sealing txawm tias thaum raug rau cov khoom abrasive thiab cov dej ntws ceev ceev. Qhov no ua rau lawv yog qhov kev xaiv txhim khu kev qha rau kev tswj cov dej ntws ntawm abrasive slurries, hmoov thiab cov ntaub ntawv granular qhov twg cov rooj zaum mos mos tuaj yeem lwj sai thiab ua tsis tiav.

5. Kev kaw thiab kev tswj xyuas kom nruj
Cov li qub uas muaj hlau zaum thiab npauj npaim yog cov uas paub txog lawv lub peev xwm kaw zoo heev thiab tswj tau qhov ntws zoo. Lub rooj zaum hlau muab lub foob kaw ruaj khov tiv thaiv lub disc, txo qhov xau thiab xyuas kom meej tias cov kua dej hauv cov txheej txheem sib cais tau zoo. Tsis tas li ntawd, cov li qub npauj npaim yog tsim los tswj qhov ntws zoo, ua rau lawv haum rau cov ntawv thov uas xav tau kev tswj qhov ntws kom meej. Kev sib xyaw ua ke ntawm kev kaw ruaj khov thiab kev tswj qhov ntws ua rau cov li qub uas muaj hlau zaum thiab npauj npaim yog qhov kev xaiv ntau yam rau ntau yam txheej txheem kev lag luam.

Zuag qhia tag nrho, qhov zoo ntawm kev siv cov hlau zawm npauj npaim li qub ua rau lawv yog thawj qhov kev xaiv rau cov lag luam uas xav tau cov kev daws teeb meem valve txhim khu kev qha, ruaj khov thiab ua haujlwm tau zoo. Txij li kev tiv taus qhov kub siab thiab cov khoom siv corrosive mus rau kev muab kev kaw nruj thiab kev tswj hwm kev ntws kom raug, cov hlau zawm npauj npaim li qub muaj ntau yam zoo uas ua rau lawv yog ib qho tseem ceeb hauv ntau daim ntawv thov kev lag luam. Raws li thev naus laus zis thiab cov ntaub ntawv txuas ntxiv mus, kev ua haujlwm ntawm cov hlau zawm npauj npaim li qub yuav txhim kho ntxiv, ua kom lawv txoj haujlwm ruaj khov ua tus neeg ua si tseem ceeb hauv kev lag luam valve.
