Spiral Electric Resistor Nicr Aloyi 1 - 5 Mohm Yotenthetsera Zinthu Zoziziritsira Mpweya

1. Kufotokozera Kwathunthu kwa Zinthu

Constantanndi aloyi ya mkuwa ndi nickel yomwe imadziwikanso kutiEureka,PatsogolondiBwatoKawirikawiri imakhala ndi 55% ya mkuwa ndi 45% ya nickel. Chinthu chake chachikulu ndi kukana kwake, komwe kumakhala kosalekeza pa kutentha kosiyanasiyana. Ma alloy ena omwe ali ndi ma coefficients ofanana ndi kutentha kochepa amadziwika, monga manganin (Cu).₈₆Mn₁₂Ni₂).

Poyesa mitundu yayikulu kwambiri, 5% (50 000 microstrian) kapena kupitirira apo, annealed constantan (P alloy) ndiye chinthu chomwe chimasankhidwa nthawi zambiri. Constantan mu mawonekedwe awa ndi yothandiza kwambiri.ductilendipo, mu utali wa gauge wa mainchesi 0.125 (3.2 mm) kapena kupitirira apo, ukhoza kusefedwa mpaka >20%. Komabe, ziyenera kukumbukiridwa kuti pansi pa zovuta zambiri zozungulira, P alloy idzawonetsa kusintha kosatha kwa resistivity ndi kuzungulira kulikonse, ndikuyambitsa zofanana.ziroKusintha kwa gauge ya strain. Chifukwa cha khalidweli, komanso chizolowezi cha gridi kulephera msanga ndi kukanikiza mobwerezabwereza, P alloy nthawi zambiri siilimbikitsidwa kuti igwiritsidwe ntchito pokanikiza cyclic strain. P alloy imapezeka ndi manambala a STC a 08 ndi 40 kuti igwiritsidwe ntchito pa zitsulo ndi mapulasitiki, motsatana.

2. Chiyambi cha Spring ndi ntchito zake

Kasupe wozungulira wozungulira, kapena kasupe wa tsitsi, mu wotchi yochenjeza.

Kasupe wothamanga kwambiri. Pamene ma coil aphwanyidwa, amatsetsereka pamwamba pa wina ndi mnzake, zomwe zimapangitsa kuti azitha kuyenda nthawi yayitali.

Akasupe ozungulira a thanki ya Stuart

Ma spring a mphamvu mu chipangizo chopindika chozungulira.

Chopingasa chopotoka pansi pa katundu

Kasupe wa masamba pagalimoto
Masiponji amatha kugawidwa m'magulu kutengera momwe mphamvu yolemetsa imagwiritsidwira ntchito kwa iwo:

Kasupe wotambasula/wowonjezera mphamvu – kasupeyu wapangidwa kuti azigwira ntchito ndi mphamvu yotambasula mphamvu, kotero kasupeyu amatambasula pamene mphamvuyo ikuyikidwapo.
Kasupe wopondereza - wapangidwa kuti azigwira ntchito ndi katundu wopondereza, kotero kasupeyo amafupika pamene katunduyo akuyikidwapo.
Kasupe wozungulira - mosiyana ndi mitundu yomwe ili pamwambapa pomwe katunduyo ndi mphamvu ya axial, katundu wogwiritsidwa ntchito pa kasupe wozungulira ndi mphamvu yozungulira kapena yopotoka, ndipo kumapeto kwa kasupe kumazungulira kudzera mu ngodya pamene katunduyo akugwiritsidwa ntchito.
Katundu wokhazikika wothandizidwa ndi masika amakhalabe chimodzimodzi nthawi yonse yopatuka.
Kasupe wosinthasintha - kukana kwa coil kuti ikule kumasiyana panthawi yopanikizika.
Kasupe wosinthasintha wa kuuma - kukana kwa coil kuti ikule kumatha kusinthidwa mosiyanasiyana mwachitsanzo ndi makina owongolera, mitundu ina ya masikape amenewa imasiyananso kutalika kwake motero imaperekanso mphamvu yoyendetsera.
Zingathenso kugawidwa m'magulu kutengera mawonekedwe awo:

Kasupe wosalala - mtundu uwu umapangidwa ndi chitsulo chosalala.
Kasupe wopangidwa ndi makina - mtundu uwu wa kasupe umapangidwa ndi makina opangidwa ndi lathe ndi/kapena kugaya m'malo mopanga coiling. Popeza amapangidwa ndi makina, kasupeyo akhoza kukhala ndi zinthu zina kuwonjezera pa elastic element. Kasupe wopangidwa ndi makina amatha kupangidwa m'malo omwe amanyamula katundu wamba monga compression/extension, torsion, ndi zina zotero.
Kasupe wa serpentine - waya wokhuthala wozungulira - nthawi zambiri amagwiritsidwa ntchito popanga mipando/mipando yamakono.
