Brass Moto Nozzles
Kuita uye Hunhu
Brassinozivikanwa nekunaka kwayo yekupisa conductivity uye yakanaka corrosion resistance. Iyi mhangura-zinc alloy inopa yakanaka machinability uye kusimba. Nekunyunguduka kwe927 ° C (1700 ° F) uye density ye8.49 g/cm³, brass inopa hunhu hwekuvimbika. Kusimba kwayo kunosvika pakati pe338-469 MPa, kuve nechokwadi chekuita kwakavimbika pasi pekumanikidzwa. Iyo yezvinyorwa yakakwirira yemagetsi conductivity inowedzerawo kupisa kugovera kushanda zvakanaka.
Common Applications uye Industries
Brass nozzles anoshandiswa zvakanyanya mukudzimisa moto, pombi dzemvura, uye marine application uko kushora uye nekupisa nyaya. Zvinonyanya kushanda munzvimbo dzine mwero makemikari kuratidzwa. Iyo malleability yechinhu inoita kuti ive yakanaka kune yakajairwa nozzle dhizaini inoda maumbirwo akaomarara.
Stainless Simbi Moto Nozzles
Kuita uye Hunhu
Simbi isina ngurainozvirumbidza pamusoro pesimba rekusimba (621 MPa) uye elastic modulus (193 GPa). Yayo chromium yemukati (≥10.5%) inogadzira yega-kugadzirisa oxide layer, ichipa yakasarudzika corrosion kuramba. Nekunyunguduka kwe1510 ° C (2750 ° F) uye kureba pakuputsika kwe70%, inochengetedza kugadzikana kwemaitiro pasi pemamiriro akanyanya.
Common Applications uye Industries
Stainless simbi nozzles inotonga makemikari kugadzirisa, offshore mapuratifomu, uye maindasitiri moto masisitimu. Ivo vanosarudzirwa maapplication anoda hupenyu hurefu uye kushoma kugadzirisa munzvimbo dzinoora.

Makiyi Ekuenzanisa Zvinhu zveNozzle Zvishandiso
Kugara kwenguva refu
Abrasion Resistance
Simbi isina tsvina inokunda ndarira munzvimbo dzinokwesha nekuda kwekuomarara kwepamusoro (150–200 HB vs 55–95 HB). Kune mhangura dzemhangura, shandisa mafirita masisitimu ekudzikisa particle ingress uye kuita ongororo yekupfeka kwekota.
High-Pressure Performance
Simbi isina tsvina inochengetedza kutendeseka pane zvinomanikidza zvinopfuura mazana matatu psi, nepo ndarira inogona kuremara pamusoro pe250 psi. Funga kumanikidza ratings paunosarudza nozzle zvinhu zve hydraulic system.
Corrosion Resistance
Brass Limitations
Brass nozzles inogadzira patina nekufamba kwenguva kana yakafumurwa kune chlorides kana sulfides. Munzvimbo dzemugungwa, dezincification inogona kuitika mukati memakore 2-3 pasina machira akakodzera.
Stainless Steel Advantage
Type 316 Stainless steel inoshingirira kupfapfaidza munyu kwe1,000+ maawa isina ngura tsvuku. Passivation marapirwo anogona kuwedzera kusadzivirirwa nekuora ne30% munzvimbo dzine acidic.
Thermal Conductivity
Brass Kubudirira
Brass inotamisa kupisa 7x nekukurumidza kupfuura simbi isina tsvina, ichiita kuti ive yakakodzera kune maapplication anoda kukurumidza kuenzana kwekushisa. Ichi chivakwa chinodzivirira kupisa kwenzvimbo mukuenderera mberi kwekudzima moto.
Stainless Steel Limitations
Iyo yakaderera thermal conductivity yesimbi isina tsvina inoda kungwarira kutonga kwemafuta. Nozzles dzingada mabhachi ekutonhodza mukupisa kwepamusoro-soro kunodarika 400°C.
Zano:Brass nozzles anodiwa kune furo masisitimu uko kudziya kwekudzora kunokanganisa kuwedzera kwereshiyo.

FAQs
Ndeapi ma nozzles endarira akanakira?
Brass inokunda mumashandisirwo asingadhuri ane tembiricha iri pakati nepakati uye kuratidzwa kwemakemikari. Yakanakira masisitimu emoto emanisipala uye zvivakwa zvekutengesa.
Sei uchisarudza simbi isina tsvina yenzvimbo dzemugungwa?
Simbi isina tsvina inodzivisa ngura yemvura yemunyu 8–10x kureba kupfuura ndarira. Type 316SS inosungirwa kune offshore application paNFPA 1962.
Kangani mhuno dzinofanira kutsiviwa?
Brass: 5-7 makore
Simbi isina tsvina: 15+ makore
Ita ongororo yegore kuti uone kutsiva nguva.
Ko brass inobata furo rinowedzera here?
Ehe, asi dzivirira mafuro asinganwi nedoro ane mapolymers - aya anomhanyisa dezincification. Shandisa simbi isina tsvina kune AR-AFFF zvikumbiro.
Ko zvinhu zvenozzle zvinokanganisa kuyerera here?
Sarudzo yezvinhu inokanganisa mazinga ekukukurwa asi kwete maitiro ekutanga ekuyerera. Iyo 1.5 ″ yebhurosi mhuno uye isina tsvina yakaenzana ichave neiyo yakafanana GPM ratings kana iri nyowani.
