Electrostatic Txau Txheej Txheem hauv kev lag luam valve
Nyob rau hauv xyoo tas los no, nrog kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, kev lag luam valve hauv tsev, tab sis kuj mus rau high-tech, high-parameter, resistant rau corrosion muaj zog, cov kev taw qhia ntawm lub neej siab. Txoj kev loj hlob no kuj tau muab cov kev xav tau siab dua rau cov txheej txheem ntawm lub valve. Electrostatic txau tshuab yog kev lag luam rau cov khoom siv no yog cov khoom siv hluav taws xob zoo tib yam li qub, xyoo no kuj yog kev kho saum npoo ntawm lub valve tau nthuav dav, tab sis tsis muaj kev tsom xam ntau yam ntawm cov ntaub ntawv thiab cov txheej txheem ua ntej vim yog cov khoom siv hluav taws xob txau. , Vim hais tias cov yam ntxwv sib txawv ntawm cov ntaub ntawv sib txawv thiab kev siv thev naus laus zis hauv kev xaiv cov khoom siv electrostatic txau yuav tsum tau ua. Nws yuav tsum tau ntau tshaj qhov ovrall kev ua tau zoo ntawm cov khoom siv tshuaj tua hluav taws xob, kev ua kom zoo dua qub ntawm cov kev cai ntawm kev tiv thaiv ib puag ncig, cov hmoov rov qab ntawm cov hmoov yuav tsum muaj kev txhawj xeeb txog cov txheej txheem txheej yuav tsum tau cuam tshuam nrog ntau hom artifacts tshwj xeeb kev loj hlob ntawm kev lag luam thiab kev lag luam thiab lwm yam.
Ntawm no kuv tau sau tseg raws li hauv qab no ob peb kev ceev faj yuav ua rau lub hauv paus valve electrostatic txau rau hauv:
- Cov txheej txheem ua ntej kho. Casting molding txoj kev ntawm kev ua cov nto oxide thiab xuab zeb blasting. Sim tsis txhob siv txoj kev txhaj tshuaj blasting. Valve xav tau qhov tseeb dua, tshwj xeeb tshaj yog nyob rau sab hauv ntawm lub valve, yuav muaj qee qhov chaw hauv zos tua blasting tsawg dua. Sandblasting zoo tswj qhov roughness thiab smoothness. Tab sis nws efficiency kuj qeeb nws drawbacks. General qhov yuav tsum tau ua rau saum npoo tiav kom ua tiav qib Sa3, qhov roughness Ra tus nqi ntawm 45 ~ 70um.
- Degreasing thiab phosphating machining yuav tsum tsis txhob tsawg. Yog hais tias lub cheeb tsam oily nto ua ntej nkag mus rau hauv cov hmoov txheej, thawj zaug tshwm sim oily txheej ho thinner. Ua raws li cov yeeb yaj kiab tsis zoo, thiab yooj yim rau kev sib pauv. Thaum kawg, txheej xim qhov txawv yog pom tseeb.
- Lub valve castings feem ntau kuj tuab, thiab yuav tsum muaj lub sij hawm preheating txaus. Cov ntsiab lus no yog generally yooj yim rau saib. Yuav tsum tsim nyog rau lub ovrall design cov hmoov txheej pipeline valve Preheat qhov cub kom khiav sijhawm txaus.
- Rau qhov loj li qub rau sab nraum zoov, yuav tsum muaj lub luag haujlwm hnyav, thermosetting hmoov txheej xaiv tsis tuaj yeem ua rau lub ntsej muag pheej yig cov hmoov txheej yog li cov neeg siv yuav tsum siv cov ntshiab epoxy hmoov txheej, thiab cov cai yuav tsum tau muab los ntawm cov chaw tsim khoom ntawm cov ntaub ntawv tshuaj ntsuam xyuas. Nyob rau hauv cov ntaub ntawv ntawm tib txoj kev txheej, sab hauv tsev hmoov txheej siv nyob rau hauv sab nraum zoov, txheej txheej lub neej ntawm cov xwm txheej zoo tib yam 6 lub hlis. Kev siv cov hmoov hnyav hnyav tuaj yeem ncav cuag ntau tshaj peb xyoos.
- Valve txheej teeb meem. Ntau tus neeg tsim khoom tau them sai sai rau qhov pom ntawm cov xim, thiab tsis tshua tau them sai sai rau qhov zoo ntawm txheej. Nyob rau hauv qhov tseeb, lub ntsiab xim thiab hmoov, tab sis kuj tseem ceeb thiab txau txoj kev.
