Maburi emhangura yemvura yemunyu anodarika mamwe maaruminiyamu munzvimbo dzegungwa nekuti mhangura inochengetedza kugadzikana kwechimiro uye mashandiro ekuyerera kwemvura kana ichinge yasangana nechloride nguva dzose. Kuenzanisa uku kwakakosha kune masisitimu ekudzivirira moto mungarava uko kuvimbika kunosarudza kushanda kwemhinduro dzenjodzi.

Mvura yeMunyu yeMarine Corrosion Brass MED Nozzles vs Aluminium Components

Maburi emhangura emvura yemunyu anonzi brass MED akagadzirwa kuti adzivirire kuora kunokonzerwa nechloride kupfuura alloys dzearuminiyamu muzvishandiso zvemoto zvemugungwa. Munzvimbo dzezvikepe, hunyoro hunogara huripo, munyu unopfapfaidzwa, uye kuoma kwemvura kunowedzera kukurumidza kuputsika kwesimbi.

Masisitimu ekudzimisa moto emugungwa anotsigira kushanda kwakasimba kwekuburitsa mvura, uye ngura inokanganisa zvakananga maitiro ekupfapfaidza nemuromo uye kudzorwa kwekumanikidzwa. Zvinoenderana nehurongwa hwekuchengetedzwa kwemoto hweIMO, michina yengarava inofanira kugara yakagadzirira kushanda mumamiriro ezvinhu akaoma ezvakatipoteredza.

Maitiro Engura Emvura Yemunyu Anokanganisa Maburi Ebhuranzi neAruminiyamu

Maburi emhangura yemvura yemunyu anowanzo sangana ne oxidation pamusoro pemvura, nepo aruminiyamu ichisangana negomba rakadzika nekuda kwekupinda kwe chloride ion. Musiyano uyu unokosha pakugara kwenguva refu kwemvura.

Kuora kwearuminiyamu mumvura yegungwa kunowedzera nekukurumidza nekuda kwekubatana kwegalvanic kana kwakabatana nesimbi isina ngura kana brass fittings. Izvi zvinotungamira mukurasikirwa kwezvinhu nekukurumidza uye kudzikira kwehunhu hwemakanika.

Nzira huru dzekuora dzinosanganisira:

1. Kuora kwegomba (kunonyanya kuwanikwa muaruminiyamu)
2. Kuora kweGalvanic (masisitimu engarava dzesimbi dzakasanganiswa)
3. Kuora kwemupata muzvigadziko zvakavharwa

Ongororo yeindasitiri kubva kuAMPP inosimbisa kuti nharaunda dzechloride dzinowedzera zvakanyanya mwero wekuora kwearuminiyamu muzvishandiso zvemoto zvemugungwa

Kuenzanisa Zvinhu: Brass vs Aluminium muMarine Fire Equipment

Manozzle esimbi emvura yemunyu ane ngura anoratidza kugadzikana kwepamusoro-soro kwemakemikari emagetsi kana tichienzanisa nearuminiyamu anoshandiswa muzvishandiso zvegungwa zvakareruka.

Brass inoumba rukoko rwe oxide runodzivirira runoita kuti ngura irambe ichingopera, nepo rukoko rwe aluminium oxide rusingagadzikane zvakanyanya kana rwuchiramba rwuchishandiswa mumvura ine munyu. Izvi zvinokonzeresa kuora nekukurumidza muma nozzles emoto akagadzirwa ne aluminium.

Tafura 1: Kushanda kweBrass vs Aluminum muMarine Conditions

Nei Brass MED Nozzles Ichipfuura Aluminium Pangarava

Maburi emhangura emvura yemunyu anodarika aruminiyamu nekuti mhangura inochengetedza kuyerera kwemukati kwakasimba kana iri mugungwa kwenguva refu. Izvi zvinoita kuti kudzima moto kurambe kuchibudirira nguva dzose.

Brass inodzivirirawo kubviswa kwesimbi, nzira iyo zinc inobviswa kubva muzvimedu zvesimbi kana yanyura mumvura yegungwa. Kusiyana neizvi, aruminiyamu inoramba ichiderera zvishoma nezvishoma muzvimiro zvinotakura kumanikidzwa.

Mitemo yeinjiniya yekuchengetedza moto inosimbisa kuchengetedza kuvimbika kwemuromo wemuchina wemvura kuti ufafadze ufambe zvakanaka uye udzore mapatani panguva dzekudzimwa kwemoto nekukurumidza.

Kukanganisa Kwazvinoita Pakushanda Kwemasystem Ekuchengetedza Moto Mugungwa

Maburi esimbi emvura ine ngura yeMED anovandudza kuvimbika kwekudzima moto muchikepe nekuderedza mwero wekukundikana panguva yekubuda kwemhepo ine simba rakawanda. Maburi esimbi ealuminium ane ngura anowanzo kukonzera kupararira kusina kuenzana kwemvura inopfapfaidzwa kana kuvharika zvishoma.

Pamidziyo yemagetsi, masisitimu ekudzima moto akabatana, zvichireva kuti kuparadzwa kwemuromo wemvura kunokanganisa kumanikidzwa kwemvura uye kushanda zvakanaka kwepombi yemvura munetwork yese.

Njodzi huru dzinobva mukuora kwealuminium:

• Kureba kwenzvimbo yekusvika kwejeti kwakaderera
• Kupararira kwepfapfaidzo kusingawanzoitiki
• Kuwedzera kwekubuda kwemvura
• Njodzi yakakura yekukundikana kwekukurumidzira

Zvishandiso zvekudzivirira moto, zvakatipoteredza pangarava (NBWorldFire Components)

Manotsi emvura yemunyu emhangura yeMED anoshanda mukati menzvimbo yakakura yekudzivirira moto wegungwa inopihwa nevagadziri vemaindasitiri vakaita seNBWorldFire.

Zvikamu zvine chekuita nebhodhi rengarava zvinosanganisira:

• Masisitimu eMoto: Masisitimu eMotoyakagadzirirwa ma "spray" anodzorwa uye mapatani ejeti munzvimbo dzegungwa.
• Mavharuvhu eMoto: Mavharuvhu eMotokudzora kupararira kwemvura mumapaipi engarava.
• Mapaipi eMoto: Mapaipi eMotoita shuwa kuti hose-to-valve yakabatana zvakachengeteka kana paine kumanikidzwa.
• Makabati eReel eMoto: Makabati eReel eMotokupa nzvimbo dzemvura dzinokurumidza kupindurwa.
• Masisitimu eMED Nozzle: Magirazi emoto epakatiyakagadzirwa zvakanangana nekutevedzera mitemo yemugungwa uye kuramba mvura yemunyu.

Tafura Yekuenzanisa: Kusarudzwa Kwezvinhu zveMarine Fire Nozzle

Tafura 2: Zvinhu Zvinoita Kuti Ushande Munzvimbo Dzine Mafambisirwo Engarava

Mari yekuchengetedza uye yehupenyu hwese munzvimbo dzegungwa

Manozzle emvura yemunyu anoderedza mari yese yekushanda kwengarava nekuderedza nguva yekutsiva ngarava uye nguva yekushanda kwengarava.

Maburi earuminiyamu anoda kuongororwa nguva nenguva nekuda kwekusagadzikana kwenzvimbo uye kusasimba kwechimiro, zvichiwedzera mari yekushanda kwevashandi vengarava.

Zvinokonzera mari yehupenyu hwese zvinosanganisira:

• Kuwanda kwekutsiva
• Nguva yekuzorora panguva yekuongorora
• Basa rekugadzirisa ngura
• Kugadziriswazve kwesystem mushure mekupfekwa

Mitemo yekuchengetedza ngarava inoratidza kudzivirira ngura senzira huru yekudzora mutengo mumasisitimu ekuchengetedza ngarava

Mitemo yeIndasitiri yeMidziyo yeKudzima Moto yeMugungwa

Manozzle emvura yemunyu anowanzo sarudzwa kuti aenderane nekutevedzwa kweMarine Equipment Directive (MED) uye mitemo yepasi rose yekuchengetedza moto.

Mhedziso: Mvura yeMunyu Kuora kweBrass MED Nozzles vs Aluminium

Manozzle esimbi emvura yemunyu anopa kuvimbika kwenguva refu zvichienzaniswa nearuminiyamu muzvishandiso zvekudzima moto zvemugungwa nekuda kwekudzivirira ngura zvakanyanya, kushanda zvakanaka kwemvura, uye kuderera kwezvinodiwa zvekuchengetedza. Kune vanofambisa ngarava, kusarudzwa kwezvinhu kunokanganisa zvakananga kugadzirira kwezvishandiso zvekuchengetedza uye kushanda zvakanaka kwemari yehupenyu hwese.

Mibvunzo Inowanzo bvunzwa

1. Sei ma nozzles emvura yemunyu anogadzirwa nesimbi yeMED achinyanya kufarirwa muzvikepe?
Maburi eBrass MED anodzivirira kuora kunokonzerwa nechloride zviri nani kupfuura aruminiyamu. Izvi zvinoita kuti moto ushande zvakanaka munzvimbo dzegungwa uko munyu, hunyoro, uye tembiricha zvinogara zvichichinja mashandiro emidziyo.

2. Aruminiyamu inokurumidza sei kukundikana mumidziyo yemoto yemugungwa?
Aruminiyamu inokundikana nekukurumidza nekuda kwengura inokonzerwa nemaion echloride mumvura yegungwa. Izvi zvinoderedza kusimba kwechimiro uye zvinokanganisa kusimba kwemushonga wekufema, zvichiwedzera njodzi yekutadza kushanda zvakanaka panguva yekurwisa moto mungarava.

3. Ko maburi emhangura eMED anoda kugadziriswa kushoma pane aruminiyamu here?
Ehe, maburi emhangura emhando yeBronze MED anowanzo da kugadziriswa zvishoma nekuti mhangura inoumba jira rekudzivirira rakagadzikana. Aruminiyamu inoda kuongororwa nekutsiviwa kakawanda nekuda kwekukurumidza kwengura mumvura ine munyu.

4. Manozzle ebrass MED anoenderana here nezvinodiwa zvekuchengetedza moto mugungwa?
Manozzle eBrass MED anowanzogadzirwa kuti asvike zvinodiwa neMarine Equipment Directive uye anoenderana nemitemo yekuchengetedza moto yeIMO, zvichiita kuti akwanise kushandiswa muzvishandiso zvekudzivirira moto zvengarava zvinoshanda mumvura dzepasi rose.

5. Ndeipi musiyano mukuru wemutengo uripo pakati pema nozzles ebrass nearuminiyamu nekufamba kwenguva?
Kunyangwe aruminiyamu ingave yakachipa pakutanga, maburi emhangura eBronze MED anoderedza mitengo yenguva refu kuburikidza nekudzikira kwekutsiva, kuderedzwa kwenguva yekushanda, uye kuvimbika kwemasisitimu munzvimbo dzinopisa dzemugungwa.
