Kugwiritsa Ntchito Aluminiyamu Aluminiyamu Apamwamba Kwambiri mu Marine Engineering

Ma aluminiyamu aloyi pakugwiritsa ntchito nsanja za helikopita zakunyanja

Chitsulo chimagwiritsidwa ntchito kwambiri ngati chomangira choyambirira pamapulatifomu akubowola mafuta akunyanja chifukwa champhamvu zake. Komabe, imakumana ndi zinthu monga dzimbiri komanso moyo waufupi ikakumana ndi chilengedwe chanyanja. M'malo opangira mafuta ndi gasi m'mphepete mwa nyanja, malo otsetsereka a helikopita amagwira ntchito yofunika kwambiri pothandizira kunyamuka ndi kutera kwa helikopita, zomwe zimathandiza kwambiri kumtunda. Ma module a helikopita opangidwa ndi aluminiyamu amagwiritsidwa ntchito kwambiri chifukwa ndi opepuka, ali ndi mphamvu zabwino kwambiri komanso osasunthika, ndipo amakwaniritsa zofunikira pakugwira ntchito.

Mapulatifomu a aluminiyamu aloyi helikopita amakhala ndi chimango ndi sitima yopangidwa ndi mbiri ya aluminiyamu yosakanikirana yokhala ndi mawonekedwe amtundu wofanana ndi chilembo "H," chokhala ndi nthiti zamatabwa zomwe zili pakati pa mbale zam'mwamba ndi zapansi. Pogwiritsa ntchito mfundo zamakina ndi mphamvu yopindika ya mbiri ya aluminiyamu alloy, nsanja imakwaniritsa zofunikira pakugwirira ntchito ndikuchepetsa kulemera kwake. Kuphatikiza apo, m'malo am'madzi, nsanja za aluminiyamu za helikoputala ndizosavuta kuzisamalira, zimakhala ndi kukana kwa dzimbiri, ndipo, chifukwa cha kapangidwe kawo kambiri, safuna kuwotcherera. Kupanda kuwotcherera kumeneku kumathetsa malo omwe amakhudzidwa ndi kutentha komwe kumalumikizidwa ndi kuwotcherera, kukulitsa moyo wa nsanja ndikuletsa kulephera.

Kugwiritsa ntchito ma aloyi a aluminiyamu m'sitima zonyamula katundu za LNG (Liquefied Natural Gas).

Pamene zida zamafuta ndi gasi zakunyanja zikupitilirabe kupangidwa, zigawo zambiri zazikulu zoperekera gasi ndi zomwe zimafunikira zimakhala zotalikirana ndipo nthawi zambiri zimalekanitsidwa ndi nyanja zazikulu. Chifukwa chake, njira yayikulu yonyamulira gasi wachilengedwe wokhala ndi liquefied ndi zombo zoyenda m'nyanja. Mapangidwe a akasinja osungiramo zombo za LNG amafuna chitsulo chokhala ndi ntchito yabwino kwambiri yotsika kutentha, komanso mphamvu zokwanira komanso kulimba. Aluminiyamu alloy zipangizo amasonyeza mphamvu apamwamba pa kutentha otsika poyerekeza ndi kutentha kwa chipinda, ndi katundu wawo wopepuka amawapanga kukhala abwino ntchito m'mlengalenga atmospheres, kumene kugonjetsedwa ndi dzimbiri.

Popanga zombo za LNG ndi akasinja osungira a LNG, 5083 aluminium alloy imagwiritsidwa ntchito kwambiri, makamaka ku Japan, m'modzi mwa omwe amalowetsa kwambiri gasi wachilengedwe. Japan idapanga matanki angapo a LNG ndi zombo zoyendera kuyambira 1950s ndi 1960s, ndi matupi akuluakulu opangidwa ndi 5083 aluminium alloy. Mitundu yambiri ya aluminiyamu, chifukwa cha kupepuka kwawo komanso kusamva dzimbiri, yakhala zida zofunika kwambiri pamapangidwe apamwamba a akasinjawa. Pakadali pano, ndi makampani ochepa okha padziko lonse lapansi omwe angapange zida za aluminiyamu zotsika kutentha kwa akasinja osungira zombo za LNG. Aluminiyamu ya ku Japan ya 5083, yokhala ndi makulidwe a 160mm, imawonetsa kulimba kwa kutentha kochepa komanso kukana kutopa.

Kugwiritsa ntchito ma aloyi a aluminiyamu pazida zam'madzi

Zida zoyendetsa sitima zapamadzi monga zigawenga, milatho yoyandama, ndi ma walkways amapangidwa kuchokera ku mbiri ya 6005A kapena 6060 aluminiyamu alloy kudzera pakuwotcherera. Madoko oyandama amapangidwa kuchokera ku mbale zowotchedwa 5754 aluminiyamu aloyi ndipo safuna kupenta kapena mankhwala opangidwa ndi mankhwala chifukwa chomanga madzi.

Aluminiyamu kubowola mapaipi

Mapaipi a aluminium alloy kubowola amakondedwa chifukwa cha kachulukidwe kakang'ono, opepuka, kuchuluka kwa mphamvu ndi kulemera kwake, torque yotsika yofunikira, kukana mwamphamvu, kukana kwa dzimbiri, komanso kutsika kwamphamvu kwa makoma a chitsime. Pamene mphamvu za makina obowola ziloleza, kugwiritsa ntchito mapaipi a aluminiyamu kubowola aloyi amatha kukwaniritsa kuya komwe mapaipi obowola zitsulo sangathe. Mapaipi obowola aluminiyamu akhala akugwiritsidwa ntchito bwino pofufuza mafuta kuyambira 1960s, ndikugwiritsa ntchito kwambiri kumayiko omwe kale anali Soviet Union, komwe adafikira kuya kwa 70% mpaka 75% ya kuya kwathunthu. Kuphatikiza ubwino wazitsulo zopangira aluminium zogwira ntchito kwambiri komanso kukana kuwonongeka kwa madzi a m'nyanja, mapaipi obowola a aluminiyamu ali ndi mwayi wogwiritsa ntchito uinjiniya wam'madzi pamapulatifomu obowola m'mphepete mwa nyanja.
