Ndeapi matanho ekudzivirira aunoziva paunenge uchiisa mavharuvhu? Mapoinzi ekutarisisa mukushandiswa kwefluorine lined plastic anticorrosive valve Kana iyo valve yakaiswa, kuitira kudzivirira simbi, jecha uye mamwe matumbi ekunze kubva pakupinda muvhavha uye kukuvadza nzvimbo yekuisa chisimbiso, zvinodikanwa kuseta sefa nevhavhavhavha; Kuti uchengetedze kucheneswa kwemhepo yakamanikidzwa, pamberi pevhavha inoda kuisa mafuta-mvura separator, kana sefa yemhepo; Kutarisa mamiriro ekushanda kwevhavha panguva yekushanda, zvakakosha kuisa chiridzwa uye kutarisa valve; Kuti uchengetedze tembiricha yekushanda, isa insulation kunze kwevhavha; Kuiswa kwemashure-valve, valve yekuyamura kana cheki valve ...... inodiwa Kana iyo valve yakaiswa, kuitira kudzivirira simbi, jecha uye mamwe miviri yekunze kubva pakupinda muvhavha uye kukuvadza nzvimbo yekuvhara, inofanirwa. kuseta sefa nevhavhavhavha; Kuti uchengetedze kucheneswa kwemhepo yakamanikidzwa, pamberi pevhavha inoda kuisa mafuta-mvura separator, kana sefa yemhepo; Kutarisa mamiriro ekushanda kwevhavha panguva yekushanda, zvakakosha kuisa chiridzwa uye kutarisa valve; Kuti uchengetedze tembiricha yekushanda, isa insulation kunze kwevhavha; Nekugadzika mushure mevhavha, inoda kugadzirisa vharafu yekuchengetedza kana cheki valve; Tichifunga nezve kuenderera kwekushanda kwevhavha, yakanakira njodzi, gadzira parallel system kana bypass system. 1. Zvivako zvekudzivirira zvekuvhara mavharuvhu: Kuti udzivise kubuda kwemavhavhavha echeki kana kudzoka kwemashure mushure mekukundikana, zvichiita kuti chigadzirwa chive nekuparara kwehutano uye njodzi, imwe kana maviri mavharuvhu akachekwa akaiswa pamberi uye shure kwevhavha yekuongorora. Kana mavharuvhu maviri ekuvhara akapiwa, cheki cheki chinogona kubviswa nyore nyore kushanda. 2 kuchengetedzwa kwevhavhavhavha yekudzivirira: pamberi uye mushure mekugadzirisa nzira yekuisa kazhinji haina kuiswa block valve, chete mumatambudziko ega, inogona kushandiswa. Kana simba repakati riine zvimedu zvakasimba, zvinokanganisa valve yekuchengetedza haigoni kuvharwa mushure mokusimuka, kuisa mutobvu-yakavharwa gedhivhavha isati yasvika uye shure kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhatipitiswe,gedhi regedhi rinofanira kunge riri munzvimbo yakazaruka zvizere,vhavha yegedhi. uye vharafu yekuchengetedza yakashongedzerwa zvakananga neDN20 yekuongorora vharuvhu kumhepo. Kana kudzoreredzwa kwewakisi uye mamwe midhiya patembiricha yekamuri yemamiriro akasimba, kana kuderedzwa kudzvanywa gasification uye yakareruka yemvura yepakati tembiricha iri pasi pe 0 madhigirii Celsius, vharuvhu yekuchengetedza inoda kupisa kwemhunga. Chengetedzo vharafu yezvinosvibisa midhiya, zvichienderana nekudzivirirwa kwekuora kwevharuvhu, funga kuwedzera corrosion isingaputike firimu painopinza yevharuvhu. Gasi rekuchengetedza vharafu rinowanzo kupihwa nevhavhavha yebypass zvinoenderana nehukuru hwayo, sechinyorwa chebhuku. . Mageji ekudzvinyirira anoiswa pamberi uye shure kwevhavha yekudzikisa kuti iite kutarisa kwekumanikidza pamberi uye mushure mevhavha. Iko kune yakazara yakavharwa yevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhadzirwe kukundikana kwevhavha inoderedza dhiri,ivhavha mushure mekudzvinyirirwa kunopfuura kudzvinyirirwa kwakajairwa kana kusvetuka,kusanganisira vharuvhu mushure megadziriro. Iyo pombi yekudonha inoiswa pamberi pevhavha kuti icheke valve, basa guru nderokubvisa rwizi runoputika, vamwe vanoshandisa musungo. Basa guru repombi yepombi ndeyekumanikidza kudzikisa kutadza kwevhavha, vhara iyo yekudzikisa vharavha isati yasvika uye mushure mekucheka-vharavhavhavha, vhura iyo bypass valve, nemaoko gadzirisa kuyerera, tamba yenguva pfupi yekutenderera basa, kuitira kugadzirisa kudzvinyirira kuderedza vharafu kana kutsiva iyo yekumanikidza yekudzikisa vharafu. 4. Zvivako zvekudzivirira zvemusungo: kune marudzi maviri epombi yepombi uye bypass pombi pamucheto wemusungo, condensate recovery uye condensate kwete kupora kubhadhara, kubudiswa uye zvimwe zvinodiwa zvakakosha zvemusungo, zvinogona kuiswa zvakafanana. Musungo une bypass valve unonyanya kushandiswa kuburitsa mvura yakawanda yakanyungudutswa kana pombi inotanga kufamba. Paunenge UCHISHANDISA MUSUNGO, HAZVIZVO ZVINOFANIRA KUDHITSA CONDENSATE KUBVUKA NEPOPI YEBYPASS, iyo inogona kuita kuti chiutsi chibude muSYSTEM yeMVURA. Mumamiriro ezvinhu akajairika, usaisa bypass pombi. Chete kana tembiricha yekudziya inodiwa zvakanyanya, iyo yekupisa michina yekuenderera mberi kugadzirwa inofanirwa kuve yakashongedzerwa nebypass pombi. Mapoinzi ekutarisisa mukushandiswa kwefluorine yakamisikidzwa epurasitiki anticorrosive vharafu Fluorine yakamisikidzwa epurasitiki anti-corrosion vharafu mupetroleum, makemikari indasitiri, mushonga, simbi, magetsi emagetsi uye mamwe maindasitiri kuonana asidhi uye alkali uye imwe yakasimba inoodza media mudziyo yave yakanyanya kushandiswa, asi nzira yekusarudza yakanaka, yakanaka kushandisa fluorine lined epurasitiki valve, maererano nevashandisi vedu pamusoro pemakore echiitiko chekushanda kwemunda, Mazano anotevera anofanira kuiswa mberi kwekushandiswa kwekushisa kwepakati, kudzvinyirira, kusiyana kwepakati uye mamwe mamiriro ezvinhu apo iyo fluorine yakamisikidzwa anti-corrosion vharafu inosarudzwa: 1, fluorine yakamisikidzwa epurasitiki vharafu yepakati tembiricha: Kambani yedu akasiyana marudzi efluorine akaiswa mavharuvhu epurasitiki, kushandiswa kwefluorine epurasitiki ndeye F46 (FEP), kushandiswa kwepakati tembiricha hakugone kudarika 150 ℃ (yepakati tembiricha inogona kuva 150 ℃ kwenguva pfupi, tembiricha yekushandiswa kwenguva refu inofanira kudzorwa mu120 ℃), kana zvisina kudaro, zvikamu zvevharuvhu zvakanamira F46 zviri nyore kupfavisa, deformation, zvichiita kuti vharafu yakavharwa isina undead, kubuda kukuru. Kana tembiricha yepakati inoshandiswa iri pasi pe180 ℃ kwenguva pfupi, uye tembiricha iri pasi pe150 ℃ kwenguva yakareba, imwe mhando yepurasitiki yefluorine inogona kusarudzwa; PFA, asi yakamisikidzwa nePFA fluorine plastiki inodhura kupfuura yakaiswa neF46 mumutengo. 2, usave neiyo negative pressure. Fluorine yakavharwa epurasitiki vharafu inofanirwa kudzivirira kushandiswa kwekumanikidza kwakashata mupombi, kana paine kumanikidza kwakashata, zviri nyore kukonzera fluorine yakamisikidzwa yepurasitiki layer muvhavhavhavha inosvetwa kunze (dhiramu kunze), kupepeta, zvichitungamira kuvhurika kwevhavha nekuvhara kukundikana. . 3, kudzvanywa, kudzvanywa kwakasiyana kunofanirwa kudzorwa munzvimbo inobvumidzwa. Kunyanya mabhero chisimbiso akaiswa fluorine epurasitiki inodzora vharafu, globe vharafu. Nekuti mabhero anogadzirwa ne tetrafluoric zvinhu, kudzvanywa uye kudzvanywa musiyano wakakura, izvo zvinogona kutungamira nyore kuputika kwemabhero. Bellows seal lined fluorine epurasitiki inodzora vharafu, kushandiswa kwemamiriro ekumanikidza, kudzvanywa kwakakura, kunogona kuchinjirwa kuPTFE kurongedza chisimbiso. 4. Mamiriro epakati efluorine akavharidzirwa epurasitiki valve haafaniri kunge ane zvimedu zvakaoma, makristasi, tsvina, nezvimwewo, kuitira kuti usasakara chigadziko chevhavha uye chigaro chevhavha chakaiswa fluorine plastiki layer kana PTFE mabhero mukushanda kwekuvhura nekuvhara. Iyo yepakati ine yakaoma zvimedu, makristasi, tsvina, sarudzo, spool, chigaro chinogona kushandiswa kuHastelloy. 5, yakarongedzerwa nefluorine plastiki inodzora vharafu inofanirwa kuenderana neinoda kuyerera (Cv kukosha) kusarudzwa kwakaringana kwesaizi yevharuvhu. Paunosarudza, kana zvichienderana nekudiwa kwetraffic (Cv) uye mamwe maitiro ehunyanzvi anoverengerwa saizi yevharuvhu inofanira kusarudzwa uye kuvhurwa kwevharuvhu, senge saizi yevharuvhu yakakura kwazvo, zvirokwazvo ichaita kuti vharafu mukuvhurwa kwenguva yakareba. nguva inomhanya, pasi pemamiriro ediki uye epakati kudzvanywa, zviri nyore kugadzira iyo yevhavha yepakati nevharuvhu tsvimbo nekukanganisa kwevezvenhau uye kuita kuti vharuvhu izununguke, Iyo valve yepakati tsvimbo mukati menguva yakareba pasi pesimba, kunyange ichaita kuti valve stem fracture. Vashandisi mukusarudzwa kwemarudzi ose efluorine akaiswa mavharuvhu epurasitiki, anofanira kunge ari kure sezvinobvira kunzwisisa, tenzi kushandiswa kwehutano mamiriro, kuitira kusarudza, kushandisa zvakanaka, kuvandudza hupenyu hwebasa revhavha. Kana ichinge yadarika chiyero chemamiriro ehunyanzvi, inofanirwa kupihwa mugadziri, uye zviyero zvinoenderana zvinofanirwa kutorwa kugadzirisa dambudziko kuburikidza nekubvunzana kwakabatana.
