Raws li ib qho ntawm cov khoom siv ntawm cov cua turbine, cov kiv cua yuav tsum tau tsim nyob rau hauv nruj raws li specifications thiab yuav tsum tau. Yog li ntawd, tsis hais txog ntawm cov khoom siv, cov qauv, cov yam ntxwv thiab kev ua haujlwm, kev ua haujlwm ntawm cov cua turbines feem ntau yuav tsum tau ua.
Aluminium alloy ntxuam hniav yog ua los ntawm cov khoom zoo 5052 aluminium alloy, uas muaj lub zog siab, lub teeb yuag, kub tsis kam thiab lub neej ntev. Qhov ntom ntawm aluminium alloy hniav yog qhov tsawg, tab sis nws lub zog yog siab heev thiab nws cov plasticity zoo, yog li nws yog dav siv hauv kev lag luam.
Aluminium alloy ntxuam hniav, 5052 txhuas daim hlau rau kiv cua aluminium impellers
Alloy Status: H32
Thickness: 1.5/2 0/2.5mm
Daim ntawv thov Scope ntawm 5052-h32 txhuas phaj: tsheb lub cev daim tawv nqaij, tsheb roj tank, tsheb qhov rooj sill, chassis txee, tsheb cav casing, kiv cua hniav
5052h32 txhuas phaj belongs rau Al-Mg series alloy, uas yog dav siv los tiv thaiv xeb txhuas. Cov hlau no muaj lub zog siab, tshwj xeeb tshaj yog qaug zog: siab plasticity thiab corrosion kuj, thiab tsis tuaj yeem ntxiv dag zog los ntawm kev kho cua sov. Thaum ib nrab txias ua hauj lwm hardening Lub plasticity tseem zoo, tab sis cov yas yog tsawg thaum lub sij hawm txias ua hauj lwm hardening, corrosion kuj yog zoo, lub weldability yog zoo, lub machinability yog tsis zoo, thiab nws yuav polished.
Aluminium-magnesium alloy kuj tseem muaj me me ntawm manganese, chromium, beryllium, titanium, thiab lwm yam. Tsuas yog qee qhov me me ntawm manganese nyob rau hauv cov hlau, feem ntau nws ua MnAl6. Lub luag haujlwm ntawm chromium hauv 5052 txhuas daim hlau zoo ib yam li cov manganese. Nws txhim kho kev tiv thaiv kev ntxhov siab corrosion, ua kom lub zog ntawm lub hauv paus hlau thiab welds, thiab txo qhov nyiam ntawm vuam tawg, tab sis nws cov ntsiab lus feem ntau tsis tshaj 0.35%.
Kev siv aluminium alloys hauv kev lag luam feem ntau yog thib ob tsuas yog hlau. Qee cov aluminium alloys tuaj yeem kho cua sov kom tau txais cov khoom siv kho tshuab zoo dua, lub cev muaj zog thiab tiv thaiv corrosion. Aluminium alloy yog yooj yim rau regenerate. Aluminium muaj qhov sib txawv me ntsis melting point thiab nws cov kev tsim dua tshiab yog qhov yooj yim. Yog li ntawd, nws yog heev nrov nyob rau hauv kev lag luam xws li tsheb thiab machinery manufacturing.
Kev ua tau zoo ntawm 5052-h32 txhuas phaj:
A: Rau cov ntawv thov uas xav tau siab plasticity thiab zoo weldability
B: Lub plasticity yog tseem zoo thaum lub sij hawm ib nrab txias ua hauj lwm hardening
C: Tsawg plasticity thaum lub sij hawm txias ua hauj lwm hardening
D: Zoo corrosion kuj thiab zoo weldability
Lub tsib-series phaj thiab sawb yog cov txhuas phaj series nrog cov kev ua tau zoo tshaj plaws ntawm yim txhuas phaj series tam sim no. Cov ntsiab lus magnesium nyob nruab nrab ntawm 3-5% thiab muaj kev tiv thaiv corrosion zoo. Nws lub ntsiab tseem ceeb yog qhov qis dua, siab tensile lub zog, siab elongation lawm tab sis nws tsis tuaj yeem siv zog los ntawm kev kho cua sov. Qhov hnyav ntawm aluminium-magnesium alloy yog qis dua li ntawm lwm cov koob nyob rau hauv tib cheeb tsam, thiab nws kuj yog siv dav hauv kev lag luam.
