Valve internal leakage criteria? Valve operation precautions? Zvinotsanangurwa zvekupenda mavharuvhu nekumaka
1, sarudza nzira yevhavha yemukati yekudonha mushure mekuvhara kwevhavha kwemaawa 4-6, shandisa infrared thermometer kuyera hunde (padyo nemuviri wevharuvhu) kana 150mm kuzasi kweiyo tembiricha yesimbi yesimbi, senge yakakura kupfuura 70 ℃, iyo. inoonekwa se "mukati mevunza". Iyi nzira inoshandiswa kune akawanda mukati mavharuvhu ekudonha. Asi mubasa chairo, takasangana nezviitiko zvakakosha zvinotevera
1) nekuda kwekumisikidzwa kwepombi, kune mamwe mavharuvhu pamberi uye mushure mekuvhiringidzwa kwekushisa kwakanyanya, sekunge akabatana nekudzvanywa kwepombi, kudonha kwejellyfish chubhu.
Kutanga, iyo valve leakage yekutsunga chiyero
1, sarudza nzira yekuvhara valve
Mushure memaawa mana-6 ekuvharwa kwevharuvhu, shandisa infrared thermometer kuyera kupisa kwesimbi pazinde (pedyo nemuviri) kana 150mm kuzasi kwemuviri, kana yakakura kupfuura 70 ° c, inoonekwa se "kudonha kwemukati". Iyi nzira inoshandiswa kune akawanda mukati mavharuvhu ekudonha.
Zvisinei, mubasa redu rinoshanda, takasangana nezviitiko zvinotevera zvinotevera:
(1) Nekuda kwekumisikidzwa kwepombi, kune mamwe mavharuvhu pamberi uye mushure mekuvhiringidzwa kwekushisa kwakanyanya, senge akabatana nemhepo yekumanikidza, jellyfish pombi musungo kana musuwo wekudonhedza, mavharuvhu aya kunyangwe akadonha akasimba, vharafu. tembiricha yehunde inodarika 70 ℃.
(2) Padivi nepadivi pinda pamusuwo wemusungo kana dhiri gonhi remusungo uye jellyfish pombi. Kana nzvimbo yevharuvhu iri padhuze nepombi pombi, sekureba chero vheji yebazi iri mupombi inodonha, tembiricha yemamwe mavharuvhu inokwira kusvika kupfuura 70 ℃, senge boiler yekudhonza valve, superheated steam drain, nezvimwe. Naizvozvo, KUTUNGAMIRIRA KWEMUKATI LEAKAGE MUAYA mavhavha KUNOFANIRA KUITWA NEDZIMWE NZIRA, SEKUYERA KUTEMIRIRA KWEMUDOWO WALL OR PRIMARY DOOR STEM TEMPERATURE KUTSVAGA KUTI KUNYORA KWEMUKATI.
Chechipiri, kushanda kwevharuvhu kunokosha kunoda kutariswa
1. Pamasuo emasuo emvura yemvura yemvura inopisa, inofanira kusimbiswa zvakare hafu yeawa mushure mekupedzwa kwekushanda kuti ibvise gomba revhavha rinokonzerwa nekuwedzera kwekushisa uye kutonhora kunotonhora.
2. Kune pombi yekupisa ine rimwe kana maviri magonhi, kutevedzana kwekushanda kwevhavha ndeyotevera: vhura gonhi kamwe chete usati wazarura gonhi kaviri; Paunenge uchivhara, unofanira kutanga wavhara gonhi kaviri uye wozovhara gonhi zvakare.
3, yekushanda kwevhavha yegedhi, inogona kungovharwa zvakakwana kana kuvhurika zvakakwana, usabvumire hafu yakazaruka hafu yakavharwa mamiriro, kuitira kuderedza kukuvadzwa kwevhavha.
Chetatu, manejimendi evharuvhu akakosha anoda kutariswa
Chikamu 1, isati yatanga yega yega yemagetsi, pneumatic valve test, test process, inofanirwa kunge iri nyanzvi in situ yekutarisa vharafu uye damper kufamba mamiriro, tarisa iyo actuator yekubatanidza tsvimbo uye pini haifanirwe kunge isina kusununguka, kukotama uye kudonha, tarisa mafambiro ekuvhurwa kweDCS uye in situ inofanirwa kuenderana, pane yepakati yekumira yemagetsi gonhi rekuyedza yepakati kumira kwakajairika. Rongedza nzira yekuchinja yegonhi ndeyechokwadi, inochinjika chiito, neyakavharika loop kune yakakodzera nyanzvi yekubatanidza bvunzo, bvunzo pneumatic gadziriso mudziyo unofanirwa kuchinjika, hapana kuvuza uye chiitiko chisina kujairika, bvunzo dzinofanirwa kumisa bvunzo kana zvisina kujairika, nenguva zivisa vashandi vekugadzirisa kubata pamwe.
Chikamu chechipiri, nguva imwe neimwe yaunotanga inofanira kunge yakanyatsoenderana nezvinodiwa zvekushanda kunoenderana, gedhi remvura ShuFang rinofanira kutarisa rakavharwa nemutemo, imwe neimwe ShuFang watergate inodzimwa (maawa gumi) mushure memaawa matanhatu, mushure megedhi remvura. ye hydrophobic tembiricha chiratidzo, inofanirwa kuve yakavakirwa papombi yevharuvhu mushure mekuongorora uye kutonga kana kuvuza kwevhavha, tembiricha inoratidza kuti hapana tembiricha inoratidza kutetepa mushure mewatergate, Iyo infrared thermometer inoshandiswa kuyera tembiricha yekumberi uye kumashure kwepombi madziro e. vharafu kana kunzwa kuona kana vharafu iri kubuda. Zvakadai semagetsi kana pneumatic valve kuvuza, inofanirwa kuvharwa hydrophobic yemagetsi gonhi kana pneumatic gonhi bhuku rekuzviparadzanisa nevamwe gonhi, re hydrophobic yemagetsi gonhi, pneumatic gonhi risina bhuku rekuzviparadzanisa negonhi, senge kuvuza, rinofanira kuzununguswa kuvhara gonhi remagetsi, uye kushaya uye kubata. kuchengetedza kurapwa. Zvakadai semanyorero gonhi leakage, iyo isipo uye kuonana kugadzirisa kurapwa.
3, nguva imwe neimwe isati yavhara chikwata, kukanganisa kwevhavha (kudonha) kunofanira kuongororwa, kuvhara kwevhavha inofanira kuiswa uye kuzivisa dhipatimendi rakakodzera rekugadzirisa.
4. Mukuvhura uye kumisa nzira kana nekumanikidza kwemvura, mushure mekuvhara (kuburitsa) gedhi remvura rakavhurwa, tarisa kana pane tembiricha mushure mevhavha kana throttle hole (musungo), kuve nechokwadi kuti inogona kuita basa re drainage (release) mvura, kudzivirira ngura kunokonzerwa nekupisa kwepombi mvura inokonzerwa nekuvharika kwevharuvhu kana pombi kana throttle hole (trap).
Kupendiwa Kwevhavha UYE MAKAKO MIRAIRO YEKUTI VARIVHU ZVINHU ZVINOITA KUTI ZVINHU ZVICHAPENDIWA PACHISINHA CHISINA-MACHINE CHEMUVIRI WEMUVIRI NEBONNET, UYE CHISIMBO CHOKUZIVISA CHECHISIMBO CHICHAPENDIRWA PABATIRO ROKUTARISA, PAKUPENDERERA, NEHANDORHE. SEZVAKATAURWA MUTAFURA PASI. Rudzi rwependi yemuchina wekufambisa unotsanangurwa sezvizvi: mudziyo wemagetsi, yakajairika mhando pendi yepakati grey; Zvitatu mune imwe (kunze, kuputika-kupikisa, anti-corrosion) mhando yakapendwa yedenga rebhuruu; Pneumatic, hydraulic, giya kufambisa uye imwe nzira yekufambisa ine vharafu chigadzirwa ruvara.
1. Kuzivikanwa kwezvikamu zvevharuvhu
Pagoko revharuvhu, pane mutsara wakatwasuka une museve. Nhamba dziri pamusoro pemutsara wakachinjika dzinoratidza mwero wezita, uye mamwe anoratidza tembiricha parameter uye kushanda nesimba. Semuyenzaniso, PNl0 uye PT510 anoshandiswa pasi pekushanda parameters ye10MPa uye 510 ℃. Nhamba iri pasi pemutsara wehorizontal inoratidza mazita edhayamita yepombi yekubatanidza.
→ inoratidza kuti vharuvhu yakatwasuka, yepakati inopinza uye yekubuda inoyerera, mumutsara wepakati wakafanana kana wakafanana.
Chrysene> inoratidza kuti chikamu chevharuvhu chiri chekurudyi-kona mhando, iyo yepakati inoita pachikamu chekuvhara.
Inoratidza kuti vharafu ine nzira nhatu uye yepakati ine akati wandei nzira yekuyerera.
