Vim yog lub luag haujlwm ntawm lub sealing element ntawm kev cuam tshuam thiab txuas, tswj thiab faib, sib cais thiab sib tov cov xov xwm hauv lub valvepassage, qhov chaw sealing feem ntau raug rau corrosion, erosion, thiab hnav los ntawm cov xov xwm, uas ua rau nws yooj yim rau kev puas tsuaj.
Cov Lus Tseem Ceeb：qhov chaw sealing; corrosion; erosion; hnav
Muaj ob qho laj thawj rau kev puas tsuaj rau qhov chaw kaw: kev puas tsuaj los ntawm tib neeg thiab kev puas tsuaj ntuj tsim. Kev puas tsuaj los ntawm tib neeg yog tshwm sim los ntawm cov yam xws li kev tsim qauv tsis zoo, kev tsim khoom, kev xaiv cov khoom siv, kev teeb tsa tsis raug, kev siv tsis zoo, thiab kev saib xyuas. Kev puas tsuaj ntuj tsim yog kev hnav thiab rhuav tshem ntawm lub valve cov xwm txheej ua haujlwm ib txwm thiab yog tshwm sim los ntawm kev xeb thiab kev yaig ntawm qhov chaw kaw los ntawm cov xov xwm.
Cov laj thawj rau kev puas tsuaj rau qhov chaw sealing tuaj yeem sau ua ke raws li hauv qab no:
Kev ua haujlwm tsis zoo ntawm qhov chaw sib khi: Qhov no feem ntau pom tseeb hauv cov qhov tsis zoo xws li cov kab nrib pleb, qhov hws, thiab cov khoom sib xyaw ntawm qhov chaw sib khi. Qhov no yog tshwm sim los ntawm kev xaiv tsis raug ntawm cov qauv vuam thiab kev kho cua sov, nrog rau kev ua haujlwm tsis zoo thaum lub sijhawm vuam thiab kev kho cua sov. Qhov nyuaj ntawm qhov chaw sib khi siab dhau lossis qis dhau vim yog kev xaiv cov khoom siv tsis raug lossis kev kho cua sov tsis raug. Qhov nyuaj tsis sib xws ntawm qhov chaw sib khi thiab kev tiv thaiv corrosion tsis zoo yog vim muaj cua tshuab cov hlau hauv qab rau ntawm qhov chaw thaum lub sijhawm vuam, uas ua rau cov khoom sib xyaw ntawm qhov chaw sib khi tsis sib xws. Tau kawg, cov teeb meem tsim qauv kuj muaj nyob rau hauv qhov no.
Kev puas tsuaj los ntawm kev xaiv thiab kev ua haujlwm tsis raug: Qhov no feem ntau yog pom tseeb hauv qhov tsis xaivlub valveraws li cov xwm txheej ua haujlwm, siv lub qhov kaw-tawm ua lub qhov kaw, ua rau muaj kev siab ntau dhau thaum kaw, kaw sai, lossis kaw tsis tiav, ua rau muaj kev yaig thiab hnav ntawm qhov chaw sib khi. Kev teeb tsa tsis raug thiab kev saib xyuas tsis zoo ua rau kev ua haujlwm tsis zoo ntawm qhov chaw sib khi, ua raulub valveua haujlwm nrog kev mob nkeeg thiab ua rau lub sealing nto puas ua ntej lub sijhawm.
Kev xeb tshuaj lom neeg ntawm cov khoom nruab nrab: Cov khoom nruab nrab nyob ib puag ncig qhov chaw sib khi ua rau cov tshuaj lom neeg cuam tshuam nrog qhov chaw sib khi yam tsis tsim cov hluav taws xob, ua rau qhov chaw sib khi puas tsuaj. Kev xeb hluav taws xob, kev sib cuag ntawm cov chaw sib khi, kev sib cuag ntawm qhov chaw sib khi thiab lub cev kaw thiablub valvelub cev, nrog rau qhov sib txawv ntawm qhov concentration thiab cov pa oxygen ntawm cov khoom nruab nrab, txhua yam tsim cov qhov sib txawv, ua rau electrochemical corrosion thiab corroding lub anode-side sealing nto.
Kev yaig ntawm cov khoom nruab nrab: Qhov no yog qhov tshwm sim ntawm kev hnav, kev yaig, thiab cavitation ntawm qhov chaw sib khi thaum cov khoom nruab nrab ntws. Ntawm qee qhov ceev, cov khoom me me uas ntab hauv cov khoom nruab nrab sib tsoo nrog qhov chaw sib khi, ua rau muaj kev puas tsuaj hauv zos. Cov khoom nruab nrab ntws ceev ceev ncaj qha yaig qhov chaw sib khi, ua rau muaj kev puas tsuaj hauv zos. Thaum cov khoom nruab nrab sib xyaw thiab ua pa ib nrab, cov npuas tawg thiab cuam tshuam rau qhov chaw sib khi, ua rau muaj kev puas tsuaj hauv zos. Kev sib xyaw ua ke ntawm kev yaig thiab kev xeb tshuaj lom neeg ntawm cov khoom nruab nrab ua rau qhov chaw sib khi puas tsuaj.
Kev puas tsuaj rau lub tshuab: Qhov chaw kaw yuav raug khawb, tsoo, thiab zawm thaum lub sijhawm qhib thiab kaw. Cov atoms ntawm ob qhov chaw kaw yuav nkag mus rau hauv ib leeg thaum kub thiab siab, ua rau muaj qhov tshwm sim ntawm kev sib txuas. Thaum ob qhov chaw kaw txav mus rau ib leeg, qhov chaw sib txuas yooj yim tawg. Qhov roughness ntawm qhov chaw kaw siab dua, qhov tshwm sim no yuav tshwm sim ntau dua. Thaum lub valve raug kaw, lub valve disc yuav tsoo thiab zawm qhov chaw kaw, ua rau muaj kev hnav hauv zos lossis qhov nkag mus rau ntawm qhov chaw kaw.
Kev puas tsuaj los ntawm kev qaug zog: Qhov chaw sib khi yuav raug hloov pauv thaum siv ntev, ua rau qaug zog thiab ua rau tawg thiab tawg. Roj hmab thiab yas yuav laus tom qab siv ntev, uas ua rau kev ua haujlwm tsis zoo. Los ntawm kev tshuaj xyuas cov laj thawj saum toj no ntawm kev puas tsuaj ntawm qhov chaw sib khi, nws tuaj yeem pom tias txhawm rau txhim kho qhov zoo thiab lub neej ntawm cov chaw sib khi valve, cov ntaub ntawv sib khi zoo, cov qauv sib khi tsim nyog, thiab cov txheej txheem ua haujlwm yuav tsum tau xaiv.
TWS valve feem ntau cuam tshuam nrogroj hmab zaum npauj npaim valve, Lub qhov rooj vag, Y-strainer, lub valve sib npaug, Wafe check valve, thiab lwm yam.
