Semudziyo-unochengetedza simba, chinobatisa kupisa kweplate dzimwe nguva chinokonzera matambudziko akasiyana-siyana panguva yekushandiswa nekuda kwenzira dzisina kunaka dzekushandisa. Tinogona kuongorora uye kugadzirisa mamwe matambudziko ari nyore isu pachedu. Pazasi isu tinoongorora uye muchidimbu matambudziko akajairika uye mhinduro dzedhitachable plate heat exchangers.
Matambudziko akajairika emaplate heat exchangers ndeaya:
Liquid cross{0}}kusvibiswa mu plate heat exchanger;
Plate heat exchanger leakage (seal leakage)
Kudonhedzwa kwekumanikidzwa kweplate heat exchanger yakakura kwazvo;
Kuora kwekutsinhanisa kupisa;
internal leakage;
Kudedera kusina kujairika uye ruzha;
Plate corrosion;
Izvi zvinotevera zvinotsanangura zvikonzero uye mhinduro kumatambudziko ari pamusoro apa chimwe nechimwe.
Liquid cross{0}}kusvibiswa mu plate heat exchanger;
Zvinokonzeresa kuti plate heat exchanger cross-linking: kusasarudzwa kweplate raw materials kunokonzera kuita ngura, kutsemuka kana kuboora kweplatet, uye mashandisirwo anoitwa haazadzise zvinodiwa pakugadzira; kusara kushushikana mushure mekutonhora kutsika kweplateti uye kusagadzikana ngura kunokonzerwa nediki diki clamping saizi panguva yekuisa; kudonha kudiki kweplate leakage groove kunokonzeresa kuwanda kwezvinhu zvinokuvadza pakati nepakati kuodza marata, zvichiita kuti{1}}batane.
Mushonga wekuyambuka-mvura ndeiyi: kutsiva marata akatsemuka kana ane maburi, uye shandisa nzira yekufambisa mwenje kutsvaga kwakatsemuka mumapureti panzvimbo; gadzirisa maitiro ekushanda anoenderana kuti asangane nemamiriro ekugadzira; iyo clamping size ye plate heat exchanger inofanira kusangana nezvinodiwa pakugadzirisa nekuunganidza, uye diki zviri nani.
Plate heat exchanger leakage (seal leakage)
Zvikonzero zvekubuda mukatiHVAC midziyo:Iyo clamping saizi haisi munzvimbo, saizi haina kuenzana kana mabhaudhi ekusunga akasununguka; mamwe gaskets ari kunze kwechisimbiso groove, pane tsvina pane huru yekuisa chisimbiso pamusoro peiyo gasket, iyo gasket yakakuvadzwa kana gasket yakwegura; ndiro yakaremara, uye gungano harina kumira zvakanaka, zvichiita kuti gasket rifambe; kune makatsemuka mundiro yekuvhara groove kana nzvimbo yekuisa chisimbiso.
Magadzirisirwo emagetsi ekudonha kweplate heat exchanger Ukuru hunofanira kunge hwakafanana uye hunoenderana.Kukanganisa kwechiyero chekumanikidza hakufaniri kunge kwakakura kudarika 0.2 * nhamba yose yeplateti, uye kuenzana pakati pemapuleti maviri ekugadzirisa hakufaniri kunge kwakakura kudarika 2 mm; iwe unogona kumaka zvikamu zvinobuda. Wobva wabvisa mutsinhanisi wekupisa uye tarisa imwe neimwe, dzorera kana kutsiva gaskets nemahwendefa; gadzirisa kana kutsiva mativi akaremara emahwendefa.
Zvikonzero zvekudzikira kwakanyanya kudonha muplate heat exchanger:
Zvikonzero zvekudonha mumidziyo yeHVAC: Saizi yekurovera haisi munzvimbo, saizi haina kuenzana kana mabhaudhi ekusunga akasununguka; mamwe gaskets ari kunze kwechisimbiso groove, pane tsvina pane huru yekuisa chisimbiso pamusoro peiyo gasket, iyo gasket yakakuvadzwa kana gasket yakwegura; ndiro yakaremara, uye gungano harina kumira zvakanaka, zvichiita kuti gasket rifambe; kune makatsemuka mundiro yekuvhara groove kana nzvimbo yekuisa chisimbiso.
Magadzirisirwo emagetsi ekudonha kweplate heat exchanger Ukuru hunofanira kunge hwakafanana uye hunoenderana.Kukanganisa kwechiyero chekumanikidza hakufaniri kunge kwakakura kudarika 0.2 * nhamba yose yeplateti, uye kuenzana pakati pemapuleti maviri ekugadzirisa hakufaniri kunge kwakakura kudarika 2 mm; iwe unogona kumaka zvikamu zvinobuda. Wobva wabvisa mutsinhanisi wekupisa uye tarisa imwe neimwe, dzorera kana kutsiva gaskets nemahwendefa; gadzirisa kana kutsiva mativi akaremara emahwendefa.
Kuora kwekutsinhanisa kupisa;
Zvikonzero zvekudonhedza kwakanyanya kudonha mundiro yekupisa kupisa: Kuyerera kwegeji blockage: zvimedu zvakasimba uye ngura zvigadzirwa zvakaiswa, zvichideredza kuyerera kwemuchinjiko chikamu; kusarudzwa kwakashata: iyo chaiyo yekuyerera mwero inodarika kukosha kwekugadzira, kana ndiro inoyerera mugero upamhi haienderane nepakati. viscosity; Shanduko mukati mezvivakwa zvepakati: Tembiricha yakaderera inokonzera kuwedzera kamwe kamwe kwepakati viscosity, kana yakamiswa nyaya inowedzera kuyerera kuramba.
Maitiro ekuita nekudonha kwakanyanya kwedzvinyiriro: Gadzirisa maparamita ekushanda kuti uderedze kuvhunduka; chenesa sefa yekupinza kuti ubvise kuvharika pamberi-kumagumo; reverse flush chiteshi chekuyerera kuti ubvise zvivharo zvidiki; Kuvharika kwakanyanya kweiyo inoyerera chiteshi: disassembly, kuchenesa uye kugadzirisa; Kusarudzwa kwakashata: kugadziridzwa kwemidziyo uye parameter optimization; Kuisa uye matambudziko ekusangana: kugadzirisa uye kugadzirisa zvakare.
internal leakage;
Zvikonzero zvekupisa kupisa kunyatsoita attenuation: Zvinetso zvepakati: Kuoma kwemvura kwakanyanyisa, zvichikonzera kuyera; yepakati ine-viscosity/coking-zvisinga pindike; kushanda kusina kunaka: -nguva yakareba pamusoro-kushanda kwekufamba, kubvongodza kwakanyanyisa, kukurumidza kuiswa kwetsvina;
kushaikwa kwekugadzirisa: hapana yakakwirira-sefa yakakwenenzverwa (precision<100 mesh) installed at the inlet, solid particles blocking the flow channel.
Nzira yekurapa: Bvisa tsvina nekuchenesa kudzorera simba rayo rekupisa uye nzvimbo yekuyerera.
Kudedera kusina kujairika uye ruzha;
Zvikonzero zvekubuda kwemukati mukatindiro inopisa exchangers:Plate kukuvadzwa: Corrosion perforation (chloride pitting, intergranular corrosion), overheing cracking, and free cracking.Kukundikana kwechisimbiso: Kukuvadzwa kwakanyanya kana kuvharwa kwechisimbiso, zvichiita kuti padambuke{1}}kuyerera kwepakati. Kusapindirana zvakanaka: Plate zvinhu hazvienderane nehunhu hwepakati (semuenzaniso, kushandisa 304 simbi isina simbi kubata chloride-ine media).
Kurapa nzira: Gadzirisa maitiro ekushanda kuderedza kushandiswa kwemvura; kupera uye kubvisa kuvhara kubvisa kukanganiswa kwemvura; kusimbisa kwechinguva kuderedza kutapurirana vibration;
Plate corrosion;
Zvikonzero zveplate corrosion: Medium corrosion: Chloride ions inoparadza passivation film (pitting corrosion), yakasimba asidhi / yakasimba alkali inowedzera kuparara kwemakemikari; Zvinetso zvezvinhu: Plate material haienderane nepakati (sekushandisa 304 stainless steel kurapa chloride-ine media); Zvinhu zvakatipoteredza: Mushure mokubvisa, nzvimbo yakasviba inokonzera oxidative corrosion, uye zvinhu zvakasiyana-siyana (carbon steel support + stainless steel plate) zvinoumba galvanic cell, zvichiita kuti electrochemical corrosion; Kukanganisa kwemaitiro: Kurapwa kusina kunaka kwekupisa mushure mekuputika kweplate, zvichiita kuti kuderedzwa kwekusagadzikana kwemiganhu yezviyo (intergranular corrosion).
Anti-nzira dzekurapa ngura: chenesa pasi kuitira kuti risanyanya kukora, gadzirisa nzvimbo yenzvimbo kuti isaora zviri pakati nepakati, uye kutsiva ndiro kuti isakara zvakanyanya.
