Boiler simbi machubhu uye mapaipi anoshandiswa kune boiler dzimba uye kupisa kunopisa
Boiler simbi machubhu uye pombi, Inoreva iyo migumo miviri yekuvhura uye isina gomba chikamu, kureba kwayo uye periphery yesimbi yakakura, zvinoenderana nenzira yekugadzira inogona kukamurwa kuita seamless simbi chubhu uye welded simbi chubhu, simbi chubhu yakatarwa nekunze. zviyero (zvakadai sedhayamita rekunze kana kureba kweparutivi) uye ukobvu hwemadziro, hukuru hwayo hwakakura kwazvo, kubva padiki dhayamita yecapillary chubhu kusvika kudhayamita yemamita mashoma epombi yakakura.Machubhu esimbi anogona kushandiswa pombi, midziyo yekupisa, indasitiri yemuchina, petroleum geological exploration, midziyo, indasitiri yemakemikari uye zvakakosha zvinangwa.
Boiler simbi machubhu uye pombi, Yakakamurwa seamless simbi pombi uye welded simbi pombi (musono pombi) mapoka maviri.Zvinoenderana nechikamu chimiro chinogona kukamurwa kuita denderedzwa chubhu uye yakakosha-yakaita chubhu, inoshandiswa zvakanyanya idenderedzwa simbi chubhu, asi kune mashoma sikweya, rectangle, semicircle, hexagonal, equilateral triangle, octagonal special-shaped steel chubhu.Kune pombi yesimbi iri pasi pekumanikidzwa kwemvura kuti iite hydraulic bvunzo kuti iedze simba rayo rekumanikidza uye mhando, pasi pekumanikidzwa kwakatarwa haibvisi, kunyorova kana kuwedzera kwevanokwanisa, imwe pombi yesimbi zvinoenderana nechiyero kana zvinodiwa zvekuyedzwa kwepadivi, kupisa. bvunzo, flattening bvunzo.
Boiler Steel Tubes Uye Mapaipi, Nzira dzekugadzira
Boiler simbi machubhu nemapombi, imhando yechubhu isina musono.Iyo nzira yekugadzira yakafanana nepombi isina musono, asi pane zvakanyanya zvinodiwa pamhando yesimbi inoshandiswa kugadzira simbi pombi.Zvinoenderana nekushandiswa kwekushisa kwakakamurwa kuita marudzi maviri eyakajairwa boiler chubhu uye yakakwirira-kumanikidza boiler chubhu.
Boiler simbi machubhu uye mapaipi, iyo mechaniki pfuma indekisi yakakosha kuve nechokwadi chekupedzisira serviceability yesimbi.Izvo zvinoenderana nemakemikari anoumbwa nesimbi uye kupisa kwekupisa system.Muchiyero chepombi yesimbi, maererano nezvinodiwa zvakasiyana-siyana zvekushandisa, zvakatarwa kusimba kwesimba (kusimba kwesimba, goho simba kana goho poindi, kurebesa) uye kuoma, kusimba zviratidzo, pamwe nezvinodiwa nemushandisi wepamusoro uye wakaderera tembiricha kuita.
① Iyo yakawanda boiler chubhu tembiricha iri pazasi 350 ℃, pombi yemumba inonyanya kugadzirwa neNo. 10, kwete.20 kabhoni simbi inopisa yakakungurutswa pombi kana inotonhora inodhonzwa pombi.
② High-pressure boiler machubhu anowanzo shandiswa pasi pekushisa kwepamusoro uye mamiriro ekumanikidza.Pasi pechiito chepamusoro tembiricha flue gasi uye mhute yemvura, oxidation uye corrosion zvichaitika.Iyo pombi yesimbi inodiwa kuti ive yakasimba yakasimba yakasimba, yakakwira oxidation corrosion resistance uye yakanaka microstructure kugadzikana.
