Ndakabata mapureti akawanda emhangura kwemakore, uyemhangura yakabviswa phosphorus (DHP, kazhinji C12200 grade)Nguva dzose inoonekwa kana welding iri chikamu chemufananidzo. Kuwedzerwa kwephosphorus kudiki uku kunobvisa okisijeni panguva yekunyunguduka, zvichikusiya uine chinhu chakachena, chakapfava, uye - chinonyanya kukosha - welds pasina matambudziko ehydrogen embrittlement anogona kutambudza coppers dzakachena. Haisi iyo yakachena kwazvo yekufambisa magetsi, asi yekugadzira matangi, heat exchangers, kana chero chinhu chinoda majoini akasimba, asingadonhedze mvura, maDHP plates anogamuchirwa nguva nenguva. Muna 2026, nekutarisa zvakanyanya pane masisitimu eHVAC anoshanda zvakanaka uye kugadzirwa kwemaindasitiri kwakavimbika, maplate aya ari kushanda nesimba sebhiza rinoshanda.
Heino pfungwa dzangu dzakananga pamusoro pezvinouya nemaplate emhangura eDHP, maindasitiri aanoshandisa nguva dzose, kuti anoenzaniswa sei nemamwe marudzi emhangura, uye kuti nei zvakaoma kuatsiva mune mamwe mabasa.
Maplate emhangura akabviswa phosphorus aripo - mapepa akachena, akati sandara akagadzirira kugadzirwa, kusungirirwa, kana kugadzirwa.
Chii Chinonyanya Kukosha paDHP Copper Plates?
Mhangura iyi inomonerwa kubva mumhangura yakabviswa oxidized, zvichikupa kugona kwakanaka kudzora ukobvu uye chimiro chetsanga chakanaka:
- Kugona kunamira zvakanaka(TIG, MIG, brazing) isina maburi kana kuputsika
- Kupisa kwakanyanyakuti kupisa kupfuure zvakanaka muma exchangers kana mapaneru
- Kuumbwa kwakanakayekukombamisa, kutsika, kana kudhonza zvakadzama mumatangi/magoko
- Kudzivirira ngura kwakasimbamunzvimbo dzine mvura kana kuti dzine mhepo yakapfava
Tine saizi dzakajairika dziripo, sedzedumahwendefa emhangura akasanganiswa nephosphorus- hwaro hwakakodzera hweKucheka kana kugadzira CNC.
Maindasitiri Anovimba Nawo
Mapureti eDHP anowanikwa panonyanya kukosha pakunamira nekufambisa kupisa:
- HVAC uye firiji (maplate ekupisa, masherufu econdenser)
- Maboiler emumaindasitiri nemidziyo yekumanikidza
- Denga rekuvaka uye jira rekuvaka (rinogara kwenguva refu, risingakuvadzi madziro)
- Ma radiator emotokari uye ma oil cooler
- Matangi ekugadzirisa makemikari (zvinokuvadza zvinyoro nyoro)
Zvinenge chero mubatanidzwa wemhangura wakagadzirwa unoda majoini akavimbika.
Kuenzanisa Kwavanoita - Uye Nei Vasingawanzotsiviwa
Kana tichienzanisa nemhangura yeETP (C11000, chinhu chakachena kwazvo), DHP ine conductivity yakaderera zvishoma (inenge 85–95% IACS vs 101%) asi inochinjika zvakanyanya - ETP inogona kubatwa nechirwere chehydrogen, zvichikonzera kutsemuka panguva yekubatidza kana iri kushanda. Mhangura isina oxygen (OFHC) yakachena asi inodhura zvakanyanya uye ichiri panjodzi yekusabvisa oxidation. Mhangura dzakasanganiswa semhangura dzinowedzera simba asi dzinoderedza conductivity uye dzinochinja maitiro ekuora.
Muganho chaiwo:phosphorus yakasara inoita kuti majoini akwanise kusungirirwa zvakanaka uye akasimba,ukuwo zvichiita kuti kupisa kushande zvakanaka pedyo nemhangura chaiyo.
Unoedza kuchinjana nayo here? Kune zvigadzirwa zvakasungirirwa zvakaita sezvishandiso zvinochinja-chinja kupisa kana matangi, dzimwe nzira dzakadai searuminiyamu dzinorasikirwa ne conductivity/heat transfer, stainless jumps inodhura uye huremu, kana kuti coppers dzakachena dzinogona kukanganisa weld. Mukushandiswa kunoda leak-tight welds pamwe nekupisa kunoshanda kwemakore ekushanda, DHP plates inowanzova sarudzo yakachengeteka uye yakasimbiswa - kuchinja kunowanzoreva kugadzirisa patsva, kuyedzwa kwakawanda, kana njodzi dzakavanzika dzekuvimbika.
Chii Chiri Kuitika Pamberi Pemapureti Emhangura eDHP
Nekushandisa simba zvakanaka, mitemo yekusimbaradza magetsi, marori matete uye emhando yepamusoro evanochinjana michina midiki ari kutariswa zvakanyanya.
Kana uri kugadzira chimwe chinhu chinoda kusungirirwa pasina musoro, tarisa yeduDHP copper plate stock or tishevedzerei– takaona zvichigadzirisa matambudziko akawanda akabatana muchitoro.
Maplate eDHP angasave iwo mhangura chaiyo, asi anoita basa racho parinokosheswa.
