Chii pokunamatidza kuti sepombi dzemhangura

Pokunamatidza - mumwe muitiro kubatana kwakaita zvinhu zvakagadzirwa Kwakashandiswa micheka, kuburikidza Pakusuma solder pakati pavo. Uyezve, mashoko aya ane Inzvimbo pfungwa akaderera kupfuura dzimwe. Kwakadaro kuvhiyiwa unoshandiswa nevakawanda sendarama yepamusoro chisungo nzira. Brazing mhangura Tubing kuwedzera upenyu remubatanidzwa akadaro, ayo chisimbiso vazvo zvaoma, nechokwadi yakakwirira nemishonga kuti ngura.

Usati watanga pachako rako basa, zviri chinodiwa tinyatsoziva inokosha zvakamisa hurongwa hwavo kuitira kudzivirira chimiro notupukanana vasingafarirwi uye vawane pamagumo unhu hwakanaka kubatana.

Akaita pokunamatidza hwemhangura pombi ane yakaoma nyoro kana solder. Mashoko okutanga rinoshandiswa panguva tembiricha anenge 425 ° C, uye bvumidzwa tembiricha yechipiri inogona kusvika 560 ° C. Kuziva mhando solder kunoenderana uwandu zvemhangura uye nezvimwe zvinhu kuti anowanika ayo sezvamunoita. Kana apo solder nokuda pokunamatidza mhangura chubhu rine sirivha, ayo tembiricha utsotso anofanira kuderedzwa.

Kuti vawane unhu hwakanaka kubatana, zvakanakisisa kushandisa yemhangura-phosphor okunze, asi avo utsotso pfungwa zvichienzaniswa sirivha iri yepamusoro zvikuru. Mhangura-ndarira mhangura-nendarira meltable zvakashandiswa nekubudisa nokuda pokunamatidza pombi mhangura. Kushandiswa Its kwakafanana zvokuimba nokutorera zvikamu pamberi muitiro, ndiko kudzivisa chidzoke ane oxide firimu, iro zvikuru kukosha kwacho. Kazhinji nekubudisa rinoshandiswa vane chimiro namatidza, apo pokunamatidza pamusoro mapaipi mhangura yekudyidzana achaparadzwa nyore.

Kuti kusaita zvikanganiso zviri mukomboni zvikamu, zviri aidawo kuomerera zvimwe mitemo. Mukomboni inofanira yakaidzwa umenshaetsya womoto, izvo zvinoitawo kuti kunonyanyisa kudziyisa. Zvakakosha kuita degreasing nesimbi hukawanika. Pakakoromorwa pakati okunze uye dzavo dzine mwero nokungwarira inofanira kuongororwa.

Brazing mhangura Tubing unotora kushandisa kubva kunze mukomboni yakawanda achichinja duku. Uyewo, iyo nzvimbo ichi kuti kudziyirwa kumusoro noruvara kuti tembiricha kunodiwa. Zvadaro, solder anogona iiswe pamusoro mukomboni uye noruvara kuparadzirwa mariri brazing tochi. In yakaumbwa chimiro, zvichaita ichiyerera nenzira panosangana, inova zvikuru kupopotedzana.

Panopera pokunamatidza nekubudisa residues vanofanira nguva dzose kubviswa. Zvikuru kukosha kuomerera imwe huru mitemo: asi kudziyisa kutenderera haafaniri kugara kwenguva refu, uye overheating zvachose kunze kwacho. Uyezve, zviri pakuraramisa yakakwana kufefetedza kudzivisa zvinokuvadza zvikuru muviri yevanhu utsi zvinosanganisira cadmium mhute.

Zvaidiwa pamusoro kunenge zvichaita aivabatsira zvikuru kuurayiwa basa, kunze nguva uye kubatsira kuita zvinodiwa mugumisiro.
