Spiral heat exchangers, seyakanyanya kushanda uye compact kupisa kupisa michina, inoshandiswa zvakanyanya mumaindasitiri emakemikari, peturu, simba, uye HVAC. Maitiro avo ekugadzira anosanganisira akawanda akakosha matanho, anosanganisira kusarudzwa kwezvinhu, kuumba, welding, kusangana, uye kuongorora, zvinoda kudzora kwakasimba kuti ive nechokwadi chemhando yechigadzirwa uye kuita.
Kugadzirira kwezvinhu ndiro danho rokutanga mukugadzirwa. Spiral heat exchanger dzinowanzoshandisa corrosion-inodzivirira uye yakakwirira-temperature-inodzivirira zvinhu zvakadai sesimbi isina tsvina, titanium alloy, kana carbon steel. Mushure mekusarudza kunoenderana nezvinodiwa zvekushanda, iyo simbi simbi inoiswa uye inochekwa kuti ive nechokwadi chedimensional chaiyo inosangana nezvinodiwa zvekugadzira.
Spiral forming ndiyo musimboti muitiro. Muchina wakatsaurirwa spiral rolling unoshandiswa kukungurutsira bepa resimbi mugero rinotenderera. Mukati mekuita uku, kutenderedza tension uye kona inofanirwa kudzorwa kuti ive nechokwadi chekufanana uye kusimba kweiyo spiral. Mushure mekugadzira, iyo spiral chiteshi inofanirwa kuderedzwa kuti ibvise kushushikana uye deformation.
Welding uye kuisa chisimbiso zvakananga zvinokanganisa kuvimbika kwemidziyo. Iyo longitudinal welds ye spiral chiteshi inosungirirwa uchishandisa otomatiki argon arc welding kana plasma welding kuti ive nechokwadi chepamusoro simba uye yakaderera deformation. Tungsten inert gasi arc welding kana brazing inoshandiswa kuvhara chiteshi kudzivirira midhiya kusanganiswa. Mushure mewelding, kuongororwa kusingakuvadzi (kwakadai seX-ray kana ultrasonic test) kunodiwa kuti uone kukanganisa mukati.
Iyo yekusangana uye yekuyedza chikamu inosanganisira welding zvinhu senge pombi bhokisi uye flanges, pamwe nekuzara kudzvanywa kuyedzwa. Midziyo yacho inoitwa bvunzo yehydrostatic (kazhinji 1.25-1.5 nguva yedhizaini yekumanikidza) uye bvunzo yekudzivirira mhepo kuti ione kumanikidza kuramba uye kuita chisimbiso. Chekupedzisira, ongororo yekuona, kuyerwa kwedimensional, uye kuenzanisa kwekupisa kunoitwa kuti ive nechokwadi chekutevedzera zviyero zveindasitiri.
Iyo spiral heat exchanger yekugadzira maitiro inobatanidza machining, kunyatso kuumba, uye welding matekiniki. Nhanho yega yega inoda midziyo yakasarudzika uye yakasimba yehutongi hwemhando, inozopedzisira yave inoshanda uye yakasimba yekutsinhana kupisa kwemidziyo inosangana nepamusoro miitiro yeindasitiri yeindasitiri.
