Imba huru yejecha
Mahombe-makamuri ekuputira jecha ndiwo anorema-midziyo yekurapisa pamusoro pebasa muindasitiri, inoshandiswa zvakanyanya kuchenesa uye kuchenesa uye-kutanga kurapa mahombe uye anorema. Pazasi, ini ndichakupa ongororo yakazara kubva pamativi maviri: minda yekushandisa uye hunyanzvi hwekushandisa.
Ini
Basa repakati reimba hombe yekuputira jecha kuchenesa uye kudzoreredza kushushikana, ichipa hwaro hwepamusoro hwemaitirwo anotevera akadai sekupfapfaidza, kukoira, uye kusunga.
Simbi chimiro uye munda wekuvaka
Mabhiriji, zviteshi zvemagetsi, uye matangi ekuchengetera: Bvisa chiyero, ngura, uye mabhanhire ekare kuti uwane hutsanana hweSa2.0-2.5 kana kupfuura.
Magadzirirwo ezvivakwa zvesimbi zvekuvaka neH-mapango asati amwaya machira ekudzivirira-kuora kana kuti asingatsvi.
Ship uye Ocean Engineering
Zvikamu zvehull, decks necabins: yakakura-kubvisa ngura uye kubvisa pendi yekare.
Offshore platforms nemabhachi masisitimu: Anti{0}}corrosion pretreatment for the harsh Marine environments.
Transportation
Kucheneswa kwepamusoro kune magadzirirwo makuru ekugadzirisa kana kuvakwa kutsva kwezvitima zvechitima nengoro (kunyanya mota dzematangi).
Mafuremu mahombe erori, zvimiro zvemichina yekuvaka: senge zvekuchera, crane booms, nezvimwe.
Simba uye Heavy Equipment
Kuputika kwejecha kwemadziro emukati nekunze eshongwe dzekugadzira magetsi emhepo ibasa rakakosha pakurwisa-corrosion coating.
Midziyo yekumanikidza, boilers, uye makemikari emidziyo: Weld seam kuchenesa, yemukati madziro oxide scale kubviswa, uye kuvandudzwa kwesimba rekuneta.
Makuru ekukanda uye mafogi: Bvisa jecha zviyo uye oxide chiyero kuratidza hurema hwepamusoro.
Aerospace
Zvikamu zvendege, makesi ezvitundumuseremusere: Pre{0}}kurapwa kwekurerutsa kushushikana, kusimbaradza kana kubatana kwezvimwe zvinhu.
Ii. Unyanzvi Hwakakosha Hwemashandisirwo uye Tsika Dzakanakisa dzeMakuru-Makuro ekuputira Majecha
Kushandisa kwakaringana uye kugadzirisa ndiwo musimboti wekuona kushanda kwakanaka, kwehupfumi uye kwakachengeteka kwekamuri yekuputira jecha.
(1) Kugadzirira uye kuronga kusati kwashanda
Workpiece marongero uye kusimudza
Ronga nzira dzekupinda uye dzekubuda dzeiyo workpiece uye kutenderera / kufamba zvinzvimbo panguva yejecha rejecha kuve nechokwadi chekuti nzvimbo dzese dzinogona kufukidzwa zvinobudirira.
Nezvekuwedzera-zvikamu zvakareba (senge tower cylinders), zvinodikanwa kushanda pamwe ne-indoor ground rails uye sandblasting trolleys kuita segmented sandblasting.
Shandisa zvizere hurefu hwekamuri yekuputira jecha uye shandisa nzira yakawanda-yekurembera kubata zvidimbu zvidiki, nokudaro uchivandudza mwero wekushandisa nzvimbo.
Abrasive kusarudzwa uye kugadzirira
Sarudza zvinoenderana nemaitiro ekuita:
Metal abrasives (jecha resimbi yakakandwa, waya yekucheka pfuti): Kuomarara kwepamusoro, hupenyu hurefu hwebasa, huchishandiswazve, hwakakodzera kusimbaradza kurapwa uye kubvisa ngura.
Non-metallic abrasives (brown corundum, quartz sand, garnet) : Ane kuoma kwepamusoro uye simba rekucheka rakasimba, uye akakodzera kuomesa ngura kana kugadzirisa pamusoro pematombo. Zvisinei, dzinobudisa huruva yakawanda uye dzinosakara nokukurumidza.
Kana mabrasives matsva akashandiswa kekutanga, anofanirwa kuita "empty run" kutenderera kubvisa guruva nemarara mukati mawo.
Abrasive mixing: Kushandiswa kwezvitsva uye zvekare mabrasives mune imwe chikamu (se3: 7) haigoni kungoita kuti kuve nechokwadi chekucheka kwakanaka asiwo kuderedza mari.
(2) Matekiniki eCore mukugadzira jecha
Kudzvinyirirwa kwemhepo uye kutonga kwekuyerera
Kudzvinyirirwa kwemhepo kunoshanda sesimba sosi: kazhinji, kumanikidza kwekushanda kunoda kuchengetedzwa pakati pe0.6 ne0.8 MPa. Kudzvinyirira kwakaderera kunotungamirira kuderera kwekuchenesa kushanda. Kudzvinyirira kwakanyanya kunogona kutyora abrasive zviri nyore, kukurumidza kupfeka uye kubvarura michina, uye workpiece inogonawo kukanganisa.
Kuyerera kweyero ndiyo kiyi yekubudirira: Gadzirisa iyo abrasive valve kuti ive nechokwadi cheunifomu uye inoenderera mberi abrasive kupa. Kuyerera kusina kugadzikana kunogona kukonzera kusaenzana kwepamusoro.
Pfaya nzira dzekushandisa pfuti
Engle: Pfuti yekupfapfaidza kazhinji iri paAngle ye70 dhigirii kusvika 80 dhigirii kumusoro kweiyo workpiece (inorambidzwa zvachose kupfapfaidza paAngle yakatwasuka ye90 dhigirii, sezvo ichigona kukonzera yakadzika craters). Kune anochinjika nzvimbo kana mahwendefa matete, iyo Angle inogona kuve idiki.
Kureba: Inowanzo chengetwa pakati pe300 ne700 mm. Chinhambwe chiri padyo zvakanyanya, zvichikonzera kusakara kwakadzama uye roughness yakakura. Chinhambwe chakanyanya, simba rinorasika uye kushanda kwakaderera.
Kumhanya kwekufamba uye trajectory: Chengetedza kumhanya kwakagadzikana uye kwakafanana, uye shandisa kutsvaira kana kurebesa kutsvaira (nekupindirana kunosvika 1/3) kudzivirira kusiiwa kana kupfapfaidza kwenzvimbo.
Kuenzanisa muenzaniso wekuona
Shandisa ISO 8501-1 kana SSPC-Vis masampuli akajairwa chero nguva kuti uenzanise magiredhi ehutsanana mushure mekuputika kwejecha (seSa 2.0, Sa 3).
Shandisa roughness comparator kana replication tepi kuti uedze chimiro chepamusoro (hukasha) kuona kuti inosangana nezvinodiwa zvekupfeka (kazhinji 50-100 microns).
(3) Equipment Maintenance uye system optimization
Iyo guruva yekubvisa system ndiyo nzira yehupenyu:
Zuva nezuva: Tarisa mutsauko wekumanikidza wefiriji cartridge / sefa bhegi uye chenesa dota munguva.
Nguva nenguva: Tarisa uone kana pulse reverse blowing system iri kushanda nemazvo kuti ive nechokwadi chekubvisa guruva. Iyo yakakundikana yekubvisa guruva system inogona kutungamirira kune yakaderera zvakanyanya kuoneka, izvo zvinokuvadza kune hutano uye zvinokanganisa kunaka kwejecha.
Abrasive kupora uye kuronga system
Gara uchiongorora scraper conveyor uye kuchenesa marara pachiratidziro kudzivirira kuvharika.
Tarisa simba remagineti simba rekuparadzanisa (kana simbi abrasives inoshandiswa) kuve nechokwadi kuti guruva, marara uye mabrasives anogona kupatsanurwa zvinobudirira.
Guruva uye zvimedu zvakanaka zvinofanirwa kubviswa zvachose kubva pakudzoreredza system nguva nenguva. Ndivo zvikonzero zvikuru zvekuderedzwa kwejecha kushanda zvakanaka uye kupfeka kwemidziyo.
Mwaya pfuti uye pfeka-nhengo dzisingachinji
Gadzirai chirongwa chenguva dzose chekutsiva, kunyanya chekupfeka-zvikamu zvisingachinjiki senge mhuno, mapaipi anoputika nejecha, uye machubhu eVenturi. Manozzles akasakara anogona kukanganisa zvakanyanya kuyerera kweabrasive, kuderedza kushanda kweanopfuura 20%.
Mapfumo akagadzirwa ne-zvakaomarara zvakadai seceramic kana boron carbide ane hupenyu hurefu kupfuura akagadzirwa neakajairika tungsten carbide.
(4) Kuchengetedza uye Kuchengetedzwa Kwezvakatipoteredza
Kudzivirirwa kwevashandi
Vashandi vanofanira kupfeka zvipfeko zvinodzivirira zvejecha zvinodzivirira (nehelmete yegesi yekunze), magirovhosi anorema-neshangu dzekuchengetedza.
Ita shuwa kuti mhepo inopihwa sutu yekudzivirira yakachena, yakaoma uye yakakwana mweya wakamanikidzwa.
Kudzora kwezvakatipoteredza
Chengetedza kushomeka kushoma kwakashata mukamuri yekuputira jecha kudzivirira guruva kuti risapunyuka.
Pakuchenesa aruminiyamu alloy uye magnesium alloy parts, zvinhu zvinoshandiswa zvinofanirwa kuputika{0}}.
Gadzirai nzvimbo dzakajeka dzekuchengetedza uye nzvimbo dzekushanda, uye vasiri-vashandi vanorambidzwa kupinda.
Kurasa tsvina
Iyo yakaunganidzwa huruva uye marara abrasives anofanirwa kubatwa semarara akasimba eindasitiri uye kuraswa mukuteerana nemirairo yekuchengetedzwa kwezvakatipoteredza, kunyanya kana aine simbi dzinorema kana pendi dzekare zvikamu.
Summary
Kushandiswa zvakanaka kwemakamuri akakura-anoputira jecha anogona kupfupikiswa se:
Pre-kuronga: Kurongeka kunonzwisisika uye kusarudzwa kweabrasive chaiyo.
Kudzora maitiro: Gadzirisa kudzvanywa kwemhepo, kudzora kuyerera kwehuwandu, shanda nemazvo, uye gara uchienzanisa.
Gadziriro nevimbiso: Dziviriro yeguruva, vimbiso yekudzokororazve, uye kutsiviwa kwezvikamu zvinosakara{0}}zvisingarambiki.
Chinokosha chekuchengeteka: Kudzivirirwa kwakasimba, kuchengetedza kudzvinyirira kusina kunaka, uye kuraswa kwemarara zvakakodzera.
Nekutevedzera aya misimboti uye matekiniki, kwete chete kunaka kwejecha uye kugona kugadzirwa kunogona kuvandudzwa zvakanyanya, asiwo mashandisirwo eabrasives uye mari yekuchengetedza michina inogona kudzikiswa zvakanyanya, kuve nechokwadi chekuchengetedza uye hushamwari hwemamiriro ekushanda.
