Kusarudza pakati pemaburi esimbi esimbi nearuminiyamu kunobva pane zvakawanda kupfuura tsika kana mutengo. Zvinhu zvese izvi zvinogona kupa kuyerera kunodiwa panzvimbo yemoto, asi zvakasiyana nehuremu, kubata, kuramba ngura, uye zvinodiwa zvekuchengetedza kwenguva refu. Chinyorwa chino chinoenzanisa maburi esimbi esimbi esimbi nesimbi kuti chiratidze kuti chinhu chimwe nechimwe chinoshanda zvakanaka sei, kuti misiyano iyoyo inokanganisa sei kuneta nekugara kwenguva refu kwemudziviriri wemoto, uye kuti ndeipi sarudzo inopa kukosha kuri nani pakushanda kwezuva nezuva uye hupenyu hwebasa.

Sei Uchienzanisa Manozzle Emoto eAruminiyamu neManozzle Emoto eBrass

Tsanangudzo yemichina yekudzima motoinoda kuongororwa kwakasimba kwehunhu hwesimbi, kunyanya kana tichienzanisa simbi yekare nesimbi dzemazuva ano dzinodzima moto dzealuminium. Kunyange hazvo simbi yagara ichitonga basa rekudzimisa moto nekuda kwekugara kwayo kwenguva refu nehuremu hwayo, kufambira mberi mukugadzira alloys dzealuminium uye kugadziriswa kwepamusoro kwakachinja maitiro ekutenga mumakumi matatu emakore apfuura.

Ndezvipi zvinodiwa zvinotsanangura mashandiro uye kukosha

Kushanda nesimba uye kukosha kwekufambisa kwemvura kunoenderana nehunhu hwemvura inoyerera, simba remagetsi, uye mutengo wehupenyu hwese. Magirazi emoto ealuminium anoderedza huremu zvakanyanya, anowanzo huremu hushoma ne40% kusvika 60% pane akaenzana nesimbi yavo yemhangura. Kune mutsetse wekurwisa we 1.5-inch, izvi zvinoreva kudzikira kubva pa 6.5 pounds kusvika 2.8 pounds chete. Musiyano uyu wehuremu unoderedza kuneta kwevanodzima moto panguva yekushanda kwenguva refu, ukuwo uchichengetedza mwero wekuyerera wakaenzana uri pakati pe 10 kusvika 250 gallons paminiti (GPM) zvichienderana nekugadzirwa kwe baffle ne bore.

Nzvimbo yekushanda uye kutenderera kwebasa zvinokanganisa sei sarudzo

Nzvimbo yekushanda inokanganisa zvakanyanya hupenyu hwemunhu uye kusakara kwemidziyo yekudzima moto. Kutenderera kwemabasa kunosanganisira kurova kongiri kana asphalt kakawanda kunoda simba guru rekugadzira, nepo kushandiswa kwesimbi munzvimbo dzine ngura kunonyanya kukonzera kusasimba kwemakemikari. Brass inobudirira munzvimbo dzine mvura yemunyu kana makemikari emuindasitiri anoramba achishandiswa, uko aruminiyamu isina chinhu inogona kukurumidza kuomeswa. Zvisinei, maburi emoto earuminiyamu emazuva ano anoshandisa anodizing yakaoma kuvhara mukaha uyu, zvichipa dziviriro yakakwana yezvakatipoteredza kune mawiri emabasa emaguta ukuwo ichichengetedza mabhenefiti anodiwa pakudzivirira moto muchimiro chemhando yepamusoro.

Zvimiro zveZvinhu uye Mashandiro Emunda

Kuongorora mashandiro emunda kunoda ongororo yakaenzaniswa yehunhu hwezvinhu zvinoshandiswa mukugadzira ma nozzle. Muyero weindasitiri wema nozzle emhangura unowanzo sanganisira brass tsvuku yakakandwa kana C36000 free-machining brass, nepo ma nozzle emoto epamusoro-soro ealuminium akagadzirwa neCNC kubva kuma 6061-T6 kana ma 7075-T6 aruminiyamu akaburitswa kunze kana kuti aircraft-grade 7075-T6.

Musiyano uripo pakati pezvinhu izvi wakanyanya kujeka. Aruminiyamu ye6061-T6 yakaburitswa ine simba rekudhonza rinosvika 45,000 psi, nepo alloys dzebrass dzakajairwa dziri pakati pe50,000 ne58,000 psi. Kunyangwe brass ichikwanisa kushivirira zvakanyanya uye isinganyanyi kukanganiswa neshinda, aruminiyamu inotsiva kuburikidza nekurapa kwepamusoro-soro. Anodizing yeHardcoat (MIL-A-8625 Type III) inoshandisa aluminium oxide layer inosvika 2 mils (0.002 inches) ukobvu, zvichiita kuti kuoma kwepamusoro kuve pedyo ne65 Rockwell C. Panyaya yekupisa, aruminiyamu inobvisa kupisa nekukurumidza, kunyangwe brass ichichengetedza kugadzikana kwechimiro pasi pekupiswa kwakanyanya kwekupisa kuri nani pane aruminiyamu.

Ndezvipi zvinodiwa nemuromo zvinofanira kuenzaniswa nevatengi kutanga

Mapoka ekutenga zvinhu anofanira kuongorora hunyanzvi hwe hydraulic ne mechanical kunze kwe base metallurgy. Zviyero zvakakosha zvinosanganisira kumanikidzwa kwekushanda—kunowanzo shandiswa pa50, 75, kana 100 PSI—uye kuenderana kweshinda dzekubatanidza, kazhinji National Hose (NH/NST) kana National Pipe Straight Hose (NPSH). Zvinhu zvemukati, zvakaita sebhora rinovhara (kazhinji simbi isina ngura kana simbi yakaputirwa nepolymer) uye chigaro (kazhinji Teflon kana specialized elastomers), zvinofanirwa kuenderana nezvinhu zvemuviri wekutanga kudzivirira ngura yegalvanic uye kuve nechokwadi chekuti mvura haipindi.

Ndeipi tafura yekufananidza inonyatsosiyanisa zvinhu zviviri izvi

Kuti pave nekugadzirwa kwezvinhu izvi zvine chekuita nesimbi uye mashandiro, matrix inotevera inosiyanisa hunhu hwekutanga hwesimbi yakajairwa uye anodized aluminium configurations.
