Daim ntawv thov ntawm conductive tooj liab alloy nyob rau hauv motors
Nyob rau hauv cov khoom siv lub cev muaj zog, tooj liab feem ntau yog siv rau hauv lub cev muaj zog windings, thiab cov nplhaib sib sau kuj tseem koom nrog hauv lub qhov txhab rotor motors; tooj liab kuj siv nyob rau hauv lub commutator ntawm DC motors. Kev soj ntsuam kom zoo thiab kev tsom xam tuaj yeem qhia tau tias cov khoom siv tooj liab siv nyob rau hauv lub nplhaib sau thiab lub twj tso kua mis commutator yuav tsum yog cov hlau alloy.
1. Daim ntawv thov ntawm conductive tooj liab alloy
(1) Cov khoom siv tooj liab feem ntau yog siv rau hauv cov khoom sib dhos thiab cov khoom sib txuas ntawm lub cev muaj zog thiab cov tshuab hluav taws xob
Cov rings collector thiab commutators ntawm motors thiab generators yuav tsum conductivity ntau dua 49.3mS / m, tensile lub zog ntau tshaj 294N / mm2, elongation ntau tshaj 2%, hardness siab tshaj 90HV, zoo tiv tauj, siab hnav tsis kam, thiab softening kub tshaj kev khiav hauj lwm kub. . Feem ntau, nyiaj tooj liab, tsis tshua muaj ntiaj teb tooj liab, cadmium tooj liab, zirconium tooj liab thiab chromium zirconium tooj liab yog siv.
Hard tooj liab feem ntau yog siv ntawm 80 degree thiab pib soften saum 150 degree. Tsis tshua muaj lub ntiaj teb tooj liab, nyiaj tooj liab thiab cadmium tooj liab yog tsim rau siv raws li commutator ntu rau motors hauv qab 250 degree. Zirconium tooj liab yog tsim rau siv raws li commutator ntu rau motors hauv qab 350 degree. Chromium-zirconium tooj liab yog tsim rau commutator ntu ntawm lub zog siab zog nrog qhov kub ntawm 350 ~ 500 degree.
(2) Siv nyob rau hauv vuam tshuab electrodes, electrode txhawb, electrode caj npab thiab conductive collector rings
Lub electrode ua qhov tsim nyog vuam tam sim no thiab xa cov vuam tsim nyog. Lub electrode txhawb lub rooj zaum thiab electrode caj npab yuav tsum muaj kev ua haujlwm siab thiab lub zog, thiab lub nplhaib conductive yuav tsum muaj kev ua haujlwm siab thiab hnav tsis kam. Muaj ntau yam ntaub ntawv yuav tsum tau welded, uas yuav tsum muaj ib co yam ntxwv:
● Cov hluav taws xob thiab thermal conductivity ntau dua li cov khoom siv vuam;
● Lub zog siab, tshwj xeeb tshaj yog hardness ntawm qhov kub thiab txias;
● Tsis muaj alloying adhesion nrog cov khoom siv vuam;
● Nws muaj kev tiv thaiv oxidation zoo thiab tsis tsim cov nplai oxide thaum siv.
2. Daim ntawv thov ntawm tooj liab alloy li electrode
● Rau vuam ntawm txhuas, magnesium lub teeb alloys thiab tooj liab alloys, nyiaj tooj liab, cadmium tooj liab, zirconium tooj liab thiab dispersion hardened tooj liab electrodes yuav siv tau;
● Rau vuam cov hlau tsis tshua muaj hlau, npib tsib xee alloy thiab cov hlau tsis tshua muaj hlau, electrodes xws li zirconium tooj liab, nyiaj chromium tooj liab, chromium tooj liab, chromium cadmium tooj liab, chromium aluminium magnesium tooj liab thiab chromium zirconium tooj liab tuaj yeem siv tau;
● Rau kev vuam ntawm cov hlau tsis muaj hlau thiab cov hlau tsis muaj cua sov, cov khoom siv hluav taws xob siab beryllium tooj liab, pob zeb diamond silicon tooj liab, npib tsib xee titanium tooj liab thiab chromium titanium tin tooj liab electrodes tuaj yeem siv.
● Rau kev vuam tshwj xeeb ntawm platinum (lub thawv, strips), kub ornaments thiab filaments, thiab thaum tooj liab tsis tso cai rau ntawm qhov chaw ntawm lub workpiece, tungsten, molybdenum, tooj liab-tungsten alloy, dispersion-strengthened tooj liab thiab composite electrodes yuav siv tau. .
● Siv rau cov cables tshwj xeeb, cov khoom siv hluav taws xob, cov kab sib txuas lus thiab cov kab sib txuas, thiab lwm yam. Feem ntau, cov nyiaj tooj liab, tsis tshua muaj lub ntiaj teb tooj liab, cadmium tooj liab, chromium cadmium tooj liab, blunt tooj liab thiab cov khoom siv hlau sib xyaw siv tau. Thaum siv, qhov siab tshaj plaws uas tso cai rau qhov kub nce siab yuav tsum tsis txhob tshaj qhov kub ntawm qhov muag ntawm cov khoom xaiv, uas yuav tsum tau ua kom muaj zog thiab muaj zog. Nws txawv ntawm kev siv. Piv txwv li, rau cables, nws yuav tsum tau hloov tau yooj yim thiab yooj yim mus cuag; rau cov khoom siv hluav taws xob, nws yuav tsum tiv taus kev co, corrosion, thiab qaug zog; rau kev sib cuag xov hlau, nws yuav tsum hnav-resistant.
● Siv nyob rau hauv reversing keyboards, springs thiab connectors rau ntau yam khoom siv hluav taws xob, cov khoom siv sib txuas lus thiab cov raj hluav taws xob, yuav tsum tau muaj zog heev, hardness thiab elastic txwv, nrog rau hnav tsis kam, corrosion kuj thiab qaug zog. Feem ntau siv yog beryllium tooj liab, titanium tooj liab, tin-phosphorus bronze, thiab lwm yam.
