Nyob rau hauv lub ntiaj teb no ntawm industrial li qub, hlau-seated npauj npaim li qub sawv tawm raws li ib tug txhim khu kev qha, zoo xaiv rau kev tswj cov ndlwg ntawm ntau yam khoom.Hom valve no yog tsim los tiv taus qhov kub thiab txias, corrosive cov ntaub ntawv, thiab abrasive media, ua rau nws muaj kev xaiv nrov hauv kev lag luam xws li roj thiab roj, kev ua tshuaj lom neeg, thiab kev tsim hluav taws xob.Hauv qhov blog no peb yuav tshawb txog qhov zoo ntawm kev siv hlau zaum npauj npaim valve thiab vim li cas nws yog thawj qhov kev xaiv rau ntau daim ntawv thov.

1. Durability thiab ntev
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov hlau zaum npauj npaim li qub yog lawv cov kav ntev thiab ntev.Tsis zoo li cov rooj zaum muag muag, uas nquag hnav thaum raug kub thiab cov khoom siv abrasive, hlau-lub rooj li qub yog tsim los tiv thaiv kev ua haujlwm hnyav.Cov rooj zaum hlau muab cov hlua khi thiab tiv thaiv kev xeb, ua kom muaj kev pabcuam ntev dua thiab txo kev saib xyuas.Qhov no ua rau hlau zaum npauj npaim li qub yog ib qho txiaj ntsig zoo rau kev lag luam uas xav tau kev ua haujlwm ruaj khov thiab kav ntev.

2. Kev siv kub kub
Hlau zaum npauj npaim li qub yog qhov zoo tagnrho rau cov ntawv thov kub uas cov rooj zaum muag muag yuav ua tsis tau.Cov rooj zaum hlau tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj kev cuam tshuam rau lawv lub peev xwm sealing, ua rau lawv zoo tagnrho rau cov txheej txheem uas muaj cov roj kub kub, chav thiab cov ntaub ntawv molten.Qhov kev muaj peev xwm tswj tau qhov kub thiab txias ua rau cov hlau-seated npauj npaim li qub yog ib qho khoom muaj nqis hauv kev lag luam xws li kev tsim hluav taws xob, petrochemicals thiab metallurgy, qhov kub tsis kam yog qhov tseem ceeb.

3. Corrosion kuj
Hauv kev lag luam uas muaj cov ntaub ntawv 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 valve.Hlau-seated npauj npaim li qub yog tsim los ntawm cov ntaub ntawv xws li stainless hlau, duplex steel thiab lwm yam corrosion-resistant alloys thiab yog haum rau tuav corrosive tshuaj thiab acidic daws.Cov rooj zaum hlau muab kev tiv thaiv kev tiv thaiv kev tiv thaiv corrosion, ua kom muaj kev ncaj ncees ntawm lub valve thiab tiv thaiv kev xau lossis tsis ua haujlwm nyob rau hauv ib puag ncig corrosive.

4. Hnav tsis kam
Rau cov ntawv thov uas muaj cov xov xwm abrasive, xws li mining, pulp thiab ntawv, thiab slurry tuav, muaj peev xwm tiv taus hnav thiab yaig yog qhov tseem ceeb.Hlau zaum npauj npaim li qub yog tsim los tiv thaiv kev hnav thiab tswj lawv qhov kev sib khi ua haujlwm txawm tias raug cov khoom abrasive thiab siab tshaj tawm ntws.Qhov no ua rau lawv muaj kev xaiv txhim khu kev qha rau kev tswj cov ntws ntawm abrasive slurries, hmoov thiab granular cov ntaub ntawv uas cov rooj zaum muag muag tuaj yeem degrade sai thiab ua tsis tiav.

5. Kev kaw nruj thiab tswj kev ntws
Hlau zaum npauj npaim li qub tau paub txog lawv cov peev xwm kaw tau zoo thiab kev tswj xyuas meej.Lub rooj zaum hlau muab lub kaw ntom nti tiv thaiv lub disc, txo cov pa tawm thiab ua kom ntseeg tau tias muaj kev sib cais ntawm cov txheej txheem kua.Tsis tas li ntawd, npauj npaim li qub yog tsim los tswj cov dej ntws zoo, ua rau lawv tsim nyog rau kev siv throttling uas yuav tsum tau tswj xyuas kom meej.Qhov kev sib xyaw ua ke ntawm kev kaw nruj thiab kev tswj ntws ua rau cov hlau zaum npauj npaim li qub rau ntau yam kev xaiv rau ntau yam kev lag luam.

Zuag qhia tag nrho, qhov zoo ntawm kev siv hlau-seated npauj npaim li qub ua rau lawv thawj qhov kev xaiv rau kev lag luam uas yuav tsum tau txhim khu kev qha, ruaj khov thiab kev ua haujlwm siab valve.Los ntawm kev tiv taus qhov kub thiab txias thiab cov khoom siv corrosive los muab kev kaw nruj thiab kev tswj xyuas meej, cov hlau-seated 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-seated npauj npaim li qub yuav tsum tau txhim kho ntxiv, ua kom lawv txoj haujlwm ua tus tseem ceeb hauv kev lag luam valve.
