Tekinoroji yeLaser Cladding: Hutsva hweGreen hunoshongedza Midziyo yePetrochemical ne "High-Performance Armor"

Muindasitiri yemafuta, chikamu chakakosha pakuchengetedzeka kwesimba renyika uye hupenyu hwemaindasitiri ekutanga, kushanda kwenguva refu uye kwakasimba kwemidziyo yekugadzira ndiyo nzira yekubatsira mashandiro anoshanda zvakanaka uye akachengeteka. Zvisinei, nzvimbo dzakanyanya kushanda - tembiricha yakakwira, kumanikidzwa kwakanyanya, ngura yakanyanya, uye kukanganiswa kwemidziyo - zvinogara zvichiedza kugara kwenguva refu kwemidziyo mikuru. Mapombi, mavharuvhu, mapaipi, ma reactor, nezvimwe zvikamu zvinoshanda se "tsinga" uye "moyo" wemaitiro ekugadzira, uye kuvimbika kwenzvimbo dzadzo dzemukati kunotarisa zvakananga hupenyu hwekushanda uye kuvimbika kweyuniti yese. Mhinduro dzechinyakare, dzakadai sekushandisa zvinhu zvinoshanda zvakanyanya mukati mese kana kuda nguva yekudzima nguva nenguva yekutsiva zvikamu, hadzingodhuri chete asiwo dzinotora nguva. Zvichienderana neizvi, tekinoroji yelaser cladding, senzira yepamusoro yekugadzira pamusoro uye kugadzira patsva, iri kupa mhinduro dzinochinja-chinja dzekuwedzera hupenyu uye kuona kushanda kwakavimbika kwemidziyo yemafuta nekushanda kwayo kwepamusoro.

I. Matambudziko Akakomba: "Kurwadziwa Kwechisikigo" Kwemidziyo yePetrochemical

Midziyo yePetrochemical inotarisana nekukuvadzwa kukuru kubva mukurwiswa kwemakemikari uye kwemuviri nemidziyo yemukati:

Kuora kwemakemikari: Pakugadzira mafuta asina kucheneswa kana zvinhu zvemakemikari zvine zvinhu zvinoparadza zvakaita sesarufa, chlorine, acid, uye alkali, simbi iri mumidziyo (kazhinji simbi yekabhoni kana simbi isina ngura) inogona kukuvadzwa nengura yakafanana, kupwanyika, uye ngura pakati pegranular, zvichikonzera kutetepa kwemadziro, kubooka, uye kutokundikana.

Kukuvara Kwevhu: Kuyerera kwezvimedu zvinokatyamadza, tsvina, utsi, nezvimwe zvinofamba-famba zvinoramba zvichipwanya nekuparadza magokora emapaipi, nzira dzekuyerera kwepombi, nzvimbo dzekuvharira chigaro chevharuvhu, nezvimwe zvikamu, zvichikonzera kurasikirwa nezvinhu uye kukuvara kwechimiro.

Kupisa kwakanyanya uye kuneta pakupisa: Ma reactor nemapombi anodziya zvakanyanya anoshanda pasi pekupisa kwakanyanya, zvichiita kuti zvinhu zvesimbi zvikanganiswe nekuoxidation uye kukambaira, uye kunyange kuneta kwekupisa kunokanganisa panguva yekupisa kunoenderana nekutanga nekudzimwa. Kukuvadzwa uku kunowanzo tungamira mukukundikana kwezvikamu zvakakosha zvemidziyo, zvichimanikidza makambani kuti avhare nguva nenguva kuti agadzirise. Nguva yega yega yekudzimwa isina kurongwa inogona kukonzera kurasikirwa kwehupfumi kwemamiriyoni eyuan uye kuisa njodzi dzekuchengetedza.

II. Tekinoroji huru: Kugadzirwa kwelaser cladding "muviri usingaparare"

Kuvhara laser tekinoroji yekugadzira zvinhu zvinowedzerwa inoshandisa danda re laser rine simba rakawanda senzvimbo yekupisa kunyungudutsa upfu hwe alloy nechikamu chakatetepa pamusoro pe substrate, nokudaro zvichiita kuti pave nesimbi yesimbi inoshanda zvakanyanya pamusoro pe substrate. Nheyo yekushandiswa kwayo mukudzivirira michina ye petrochemical inogona kupfupikiswa seinotevera:

1. Kudzora simba nemazvo: Simba remwaranzi yelaser rakanyanya kuwanda, kumhanya kwekupisa nekutonhodza kunokurumidza zvikuru, kupinda kwekupisa nenzvimbo inokanganiswa nekupisa ku substrate kudiki kwazvo, uye kushanduka kwebasa nekudzikira kwekushanda zvinodziviswa.

2. Zvakanakira Kubatanidza Zvine Metallurgical: Chigadziko che cladding ne base material zvinonyunguduka uye zvinopararira pamwe chete kana tembiricha yakakwira, zvichiita kuti pave nechisungo chakasimba che metallurgical. Chisungo ichi chakasimba kupfuura zvisungo zve mechanical zvinowanikwa nemaitiro echinyakare akadai sekupfapfaidza ne electroplating, uye coating yacho haikanganisike.

3. Rusununguko rwekugadzira zvinhu: Unogona "kugadzirisa" zvichienderana nemamiriro chaiwo ekushanda uye kusarudza upfu hwakakodzera hunodzivirira ngura, hunodzivirira kupera kana hunodzivirira kupisa kwakanyanya (senge nickel-based, cobalt-based, iron-based alloys uye metal-ceramic composites) kuti uwane musanganiswa wakanakisa we "matrix bearing yakanaka uye strong surface bearing".

Pamichina ye petrochemical, kunyanya pamusoro pemukati memapaipi nema reactors, michina yakakosha ye laser cladding yemukati inowanzo shandiswa kugadzira otomatiki uye yakaenzana munzvimbo dzakaoma uye dzakamanikana, zvichiita kuti machira acho ave emhando yepamusoro uye asina zvikanganiso.

III. Mhedzisiro yekushandisa: kuisa hupenyu hutsva mumidziyo mikuru

Kushandisa tekinoroji yelaser cladding pamidziyo yakasiyana-siyana yepetrochemical kunogona kuunza mabhenefiti ipapo ipapo uye kwenguva refu:

Mapombi (mapombi epakati, mapombi anodzokorodza): Kufukidza simbi ine chromium yakawanda, tungsten carbide nezvimwe zvinhu zvisingapfeki pamusoro pezvikamu zvinoyerera zvakaita semapombi nema impellers zvinogona kudzivirira zvikuru slurry nezvidimbu, uye kuwedzera nguva yekuderera kwekushanda kwayo kakawanda.

Mavharuvhu (mavharuvhu ebhora, mavharuvhu egedhi, mavharuvhu eglobe): Ma alloys akagadzirwa ne cobalt akadai se Stellite akaiswa pamusoro pechisimbiso chechigaro chevharuvhu nepakati pevharuvhu (bhora) kuitira kuti ive nechokwadi chekuti inodzivirira kupera uye inodzivirira ngura, kubvisa kubuda kwemvura mukati, uye kuita kuti ivharwe zvakasimba.

Masisitimu emapaipi (mapaipi akatwasuka, magokora, matinji): Kunyanya pamagokora anowanzo kurumuka, kufukidza nejira rinodzivirira kupera simba uye rinodzivirira ngura kunogona kudzivirira rusvingo rwese rwemukati zvakaenzana, kugadzirisa zvachose dambudziko rekuboorwa kwepakarepo kunokonzerwa ne "skirting" effect yemuno, uye kuwedzera hupenyu hwepaipi nekatatu kusvika kashanu.

Reactor (muviri wekettle, agitator, zvikamu zvemukati): Rusvingo rwemukati rwakafukidzwa neHastelloy kana 625 alloy inodzivirira kupisa kwakanyanya, carburization, uye acid nealkali corrosion, zvichibudirira kudzivirira kuputsika kwereaction medium, kuchengetedza nzvimbo yakachena reaction, uye kuona kuti chigadzirwa chakanaka.

IV. Kupfuura Dziviriro: Kusvetuka Kwakazara

Kukosha kwetekinoroji yelaser cladding kunopfuura "kugadzirisa". Iyi zvakare inzira yepamusoro ye "kudzivirira kushingaira" uye "kugadzira patsva", ichiunza kuvandudzwa kwakawanda kumakambani epetrochemical:

Wedzera nguva yekugadzirisa uye vimbisa kushanda kwenguva refu: Kuvandudzwa kukuru kwekuvimbika kwemidziyo kwakawedzera zvishoma nezvishoma nguva yekugadzirisa kubva mugore rimwe kusvika maviri apfuura kusvika kumakore matatu kusvika mana kana kupfuura, izvo zvinosangana zvakakwana nezvinodiwa zvekushanda "zvakachengeteka, zvakagadzikana, kwenguva refu, zvizere uye zvakanaka kwazvo" zveindasitiri yemazuva ano yemakemikari.

Kuderedzwa kwemitengo, kuvandudza mashandiro, uye budiriro inoenderera mberi: Zvichienzaniswa nekutsiva zvachose zvinhu zvinodhura zvine alloy yakawanda, laser cladding inosimbisa chete pamusoro, ichichengetedza mari inodarika 70%. Inobvumirawo kugadzirwa patsva kwezvinhu zvakaraswa, zvichiita kuti mashandiro azvo apfuure matsva, zvichienderana nemisimboti yehupfumi hwakatenderera uye budiriro yezvakatipoteredza.

Kusimbisa zvipingamupinyi zvekuchengetedza: Kubvisa zvakanyanya njodzi dzakavanzika dzetsaona dzakakomba dzakadai sekubuda kwemvura pakati nepakati, moto nekuputika kunokonzerwa nekutetepa kwemadziro emidziyo uye kubooka kwengura, uye kuvaka chipingamupinyi chakasimba chehunyanzvi kuti pave nekuchengetedzwa. kugadzirwa.

Mhedziso

Tekinoroji yeLaser cladding, ine maficha ayo edhijitari, akarurama, uye anochinjika, iri kuchinja zvakanyanya kugadziriswa kwemidziyo muindasitiri yemafuta. Inopa michina iyi yakakosha yeindasitiri "nhumbi dzekudzivirira dzinoshanda zvakanaka," zvichiita kuti ikwanise kutsungirira mamiriro ekushanda akaomarara. Nekuwedzera kwekushandiswa kwetekinoroji uye kugadzirisa mashandiro, laser cladding yagadzirira kuva imwe yetekinoroji huru inovimbisa kuchengetedzeka kwemukati, kudzikiswa kwemitengo, kuvandudzwa kwekushanda, uye kukura kwakasimba kwemakambani emafuta, zvichiisa simba retekinoroji mukushanda kwakasimba kwemaindasitiri esimba nemakemikari eChina.
