Makemikari mapaipi uye mavharuvhu chikamu chakakosha chekugadzirwa kwemakemikari uye chinongedzo cheakasiyana makemikari michina. Mavharuvhu mashanu anonyanyozivikanwa mumapaipi emakemikari anoshanda sei? Chinangwa chikuru? Ndeapi mapombi emakemikari uye mavharuvhu ekuisa? (11 marudzi emapombi + 4 marudzi epombi fittings + 11 mavharuvhu makuru) Kemikari pombi, zvinhu zvose izvi zvinogoneka muchinyorwa chimwe!

Makemikari mapaipi uye fittings mavharuvhu

Mhando dzemapombi emakemikari anorongedzerwa nezvinhu: mapaipi esimbi uye mapaipi asina-simbi.

Metal chubhu

Kanda mapaipi esimbi, mapaipi esimbi emusono, pombi dzesimbi dzisina musono, pombi dzemhangura, pombi dzealuminium, uye pombi dze lead.

① Kanda simbi pombi:

Cast iron pipe ndeimwe yeanowanzo shandiswa pombi mumapaipi emakemikari.

Nekuda kwe brittleness yayo uye kusasimba kwekubatana kwayo, inokodzera chete kuendesa yakaderera-pressure media, uye haina kukodzera kutakura yakakwirira-tembiricha uye yakanyanya-kudzvanywa chipfu uye chepfu uye chinoputika. Inowanzoshandiswa mumapombi emvura epasi pevhu, gasi mains uye pombi dzesuweji. Izvo zvinotsanangurwa zvemapombi esimbi zvakakandwa zvinoratidzwa neF mukati dhayamita × madziro ukobvu (mm).

②Seamed simbi pombi:

Seam simbi mapaipi akakamurwa kuita akajairwa emvura gasi pombi (kumanikidza kuramba 0.1～1.0MPa) uye gobvu pombi (kudzvinyirira kuramba 1.0～0.5MPa) zvinoenderana nekushanda kwavo kumanikidza.

Inowanzo shandiswa kutakura zvinodzvinyirira zvakaita semvura, gasi, kupisa chiutsi, mweya wakamanikidzwa, uye oiri. Mapaipi ane galvanized anodaidzwa kuti galvanized iron pipes kana galvanized pipes. Idzo dzisina marita dzinonzi mapaipi esimbi nhema. Tsanangudzo dzayo dzinoratidzwa maererano nedhayamita yezita. Hudiki hwezita dhayamita i6mm uye huwandu hwepamusoro hwezita i150mm.

③Seamless simbi pombi:

Zvakanakira seamless simbi pombi ndiyo yunifomu unhu uye yakakwirira simba.

Zvinhu zvacho isimbi yekabhoni, simbi yemhando yepamusoro, simbi yakaderera-alloy, simbi isina tsvina, uye simbi isingapise kupisa. Nekuda kwemaitiro akasiyana ekugadzira, kune marudzi maviri: hot-yakakungurutswa seamless simbi mapaipi uye inotonhora-inodhonzwa musono seamless pombi. Muinjiniya yepombi, mapaipi anopisa anokungurutswa anowanzoshandiswa kana dhayamita richipfuura 57mm, uye mapaipi anodhonzwa nechando anowanzoshandiswa kana dhayamita iri pasi pe57mm.

Mapombi esimbi asina musono anowanzo shandiswa kutakura marudzi ese emagasi akatsikirirwa, mhute uye zvinwiwa, uye anogona kumira tembiricha yepamusoro (anenge 435°C). Mapaipi esimbi alloy anoshandiswa kutakura corrosive media, pakati peiyo inopisa-resistant alloy pombi inogona kumira tembiricha inosvika 900-950 ℃. Tsanangudzo yepombi yesimbi isina musono inoratidzwa neF mukati dhayamita × madziro ukobvu (mm).

Iyo yakakura yekunze dhayamita yepombi inodhonzwa inotonhora ndeye 200mm, uye yakakura yekunze dhayamita yepombi inopisa yakakungurutswa i630mm. Mapombi esimbi asina musono akakamurwa kuita mapaipi asina musono uye akakosha mapombi asina musono zvinoenderana nekushandisa kwawo, senge peturu inopwanya pombi dzisina musono, boiler mapaipi asina musono, uye mapombi asina musono fotereza.

④ Pombi yemhangura:

Iyo chubhu yemhangura ine yakanaka yekupisa kupisa.

Inonyanya kushandiswa mumapaipi emidziyo yekutsinhanisa kupisa uye midziyo ye cryogenic, dzvinyiriro yekuyeresa machubhu kana kuendesa mvura yakamanikidzwa, asi kana tembiricha yakakwira kupfuura 250 ℃, haina kukodzera kushandiswa pasi pekumanikidzwa. Nemhaka yokuti mutengo wacho unodhura, unowanzoshandiswa munzvimbo dzakakosha.

⑤Aluminum chubhu:

Aluminium ine yakanaka corrosion resistance.

Aluminium machubhu anowanzo shandiswa kutakura midhiya senge concentrated sulfuric acid, acetic acid, hydrogen sulfide uye carbon dioxide, uye anowanzoshandiswa mukuchinjana kupisa. Aluminium machubhu haadziviriri alkali uye haagone kushandiswa kutakura alkaline mhinduro nemhinduro dzine chloride ion.

Sezvo simba remagetsi realuminium chubhu rinoderera zvakanyanya nekuwedzera kwekushisa, tembiricha yekushandisa yealuminium chubhu haigone kudarika 200 ° C, uye tembiricha yekushandiswa ichave yakaderera kune yakamanikidzwa pombi. Aluminium ine zvinhu zviri nani zvemuchina patembiricha yakaderera, saka aluminium nealuminium alloy machubhu anonyanya kushandiswa mumidziyo yekuparadzanisa mweya.

⑥ Mutobvu pombi:

Mapombi emutobvu anowanzo shandiswa semapaipi ekutakura acidic media. Vanokwanisa kutakura 0.5% -15% sulfuric acid, carbon dioxide, 60% hydrofluoric acid, uye acetic acid ine mutsara usingasviki 80%. Haina kukodzera kutakura nitric acid, hypochlorous acid uye mamwe midhiya. Iyo yakanyanya tembiricha yekushanda yepombi inotungamira ndeye 200 ℃.

Kwete-simbi chubhu

Pombi yepurasitiki, pombi yepurasitiki, pombi yegirazi, pombi dzeceramic, simende pombi.

①Pombi yepurasitiki:

Zvakanakira mapaipi epurasitiki yakanaka corrosion resistance, huremu huremu, kuumba zviri nyore uye nyore kugadzirisa.

Izvo zvisingabatsiri isimba rakaderera uye kushomeka kwekudzivirira kupisa.

Parizvino, mapaipi epurasitiki anonyanya kushandiswa akaoma polyvinyl chloride mapaipi, akapfava polyvinyl chloride pombi, polyethylene pombi,polypropylene pombi, uye pombi dzesimbi dzine polyolefin uye polychlorotrifluoroethylene dzakapfapfaidzwa pamusoro.

②Rubber chubhu:

Iyo rubha chubhu ine yakanaka corrosion kuramba, huremu huremu, yakanaka plastiki, inochinjika uye nyore kuisirwa uye disassembly.

Machubhu erabha anowanzo shandiswa anowanzo kugadzirwa nerabha rechisikigo kana rekugadzira rabha, uye akakodzera nguva apo zvinodikanwa zvekumanikidza hazvina kukwirira.

③Glasi chubhu:

Iyo girazi chubhu ine zvakanakira corrosion kuramba, kujeka, kuchenesa kuri nyore, kushomeka kushomeka, uye mutengo wakaderera. Izvo zvisingabatsiri ndezvekuti ine brittle uye haigoni kumira kumanikidziro.

Inowanzoshandiswa mukuedza kana kuedza mamiriro ebasa.

④Ceramic chubhu:

Makemikari ceramics akafanana negirazi uye ane yakanaka corrosion resistance. Mukuwedzera kune hydrofluoric acid, fluorosilicic acid uye alkali yakasimba, inogona kumira zvakasiyana-siyana zveinorganic acids, organic acids uye organic solvents.

Nekuda kwesimba rayo rakaderera uye brittleness, inowanzoshandiswa kubvisa corrosive media mumasuweji uye pombi dzekufema.

⑤Simende pombi:

Inonyanya kushandiswa muzviitiko apo zvinodiwa zvekumanikidzika uye kuiswa chisimbiso kwepombi yekubatanidza haisi yakakwirira, zvakadai semvura yepasi pevhu uye pombi dzemvura.
