ZSTX 15-68℃ Pedent Chrome plated Fire sprinkler heads

Incazelo emfushane:

Ipendenti (ngesinye isikhathi ibhalwe ukuthi “pendant”) isifafazi somlilo silenga emapayipini angaphezu kosilingi futhi sisabalalisa amanzi ngephethini ebume noma eyikholi sisebenzisa i-convex deflector.Ngokungafani nezifafazi ezilengayo ezifihliwe ezicasha ngemva kwamapuleti okuhlobisa, inhloko yesifafazi somlilo elengayo yendabuko ihlala ibonakala ngemva kokufakwa.

Liyini ikhanda lokufafaza elilengayo?

Ipendenti (kwesinye isikhathi ibhalwe ukuthi "pendant") isifafazi somlilo silenga emapayipini osilingi angaphezulu futhi sisabalalisa amanzi ngephethini ebume noma eyikholi sisebenzisa i-convex deflector.Ngokungafani nezifafazi ezilengayo ezifihliwe ezicasha ngemva kwamapuleti okuhlobisa, inhloko yesifafazi somlilo elengayo yendabuko ihlala ibonakala ngemva kokufakwa.

Sithini isifafazi sempendulo esijwayelekile?

Lokhu kubhekisela kumakhanda okufafaza anenkomba yesikhathi sokuphendula (RTI) angaphezu kuka-80 (m * s)½ nangaphansi noma alingana no-350 (m * s) ½.
Ukwelashwa okungaphezulu kwemikhiqizo
Lo mkhiqizo uyi-chrome ebekwe phezulu.Isendlalelo sokucwenga se-chromium sinokuqina okuphezulu, okungahlukahluka kububanzi obungu-400 ~ 1200hv ngokuya ngokwakheka kwesixazululo sokucwenga nezimo zenqubo.Isendlalelo se-chromium plating sinokumelana nokushisa okuhle.Uma ishisiswe ngaphansi kuka-500 ℃, ukucwebezela kwayo nobulukhuni bayo abukho uguquko olusobala.Lapho izinga lokushisa lingaphezu kuka-500 ℃, liqala ukwenza i-oxidize futhi lishintshe umbala, futhi lapho izinga lokushisa lingaphezu kuka-700 ℃, ubulukhuni buqala ukwehla.I-coefficient ye-friction coefficient ye-chromium, ikakhulukazi i-coefficient eyomile, iphansi kakhulu kuzo zonke izinsimbi.Ngakho-ke, ungqimba lwe-chromium Plating lunokumelana okuhle kokugqoka.
Isendlalelo se-chromium plating sinokuzinza okuhle kwamakhemikhali futhi asisebenzi ku-alkali, i-sulfide, i-nitric acid nama-asidi amaningi aphilayo, kodwa singancibilika ku-hydrochloric acid (efana ne-hydrochloric acid) kanye ne-hot sulfuric acid.
Ebangeni lokukhanya elibonakalayo, amandla okubonisa e-chromium angaba ngu-65%, phakathi kwesiliva (88%) ne-nickel (55%), futhi ngenxa yokuthi i-chromium ayishintshi umbala, ingakwazi ukugcina amandla ayo okubonisa isikhathi eside, okuwukuthi kangcono kunesiliva ne-nickel.
