Spiral Electric Resistor Nicr Alloy 1 - 5 Mohm Yazinthu Zotenthetsera za Air Conditioner

1.Kufotokozera Kwazinthu Zazikulu

Constantanndi aloyi yamkuwa-nickel yomwe imadziwikanso kutiEureka,Patsogolo,ndiBwato. Nthawi zambiri imakhala ndi 55% yamkuwa ndi 45% nickel. Mbali yake yayikulu ndi resistivity yake, yomwe imakhala yosasinthasintha pa kutentha kwakukulu. Ma aloyi ena okhala ndi ma coefficients otsika omwewo amadziwika, monga manganin (Cu₈₆Mn₁₂Ni₂).

Pakuyezera mitundu yayikulu kwambiri, 5% (50 000 microstrian) kapena kupitilira apo, annealed constantan (P alloy) ndiye gridi yosankhidwa nthawi zambiri. Constantan mu mawonekedwe awa kwambiriductile; ndipo, mu gauge kutalika kwa 0.125 mainchesi (3.2 mm) ndi utali, akhoza kusefa ku> 20%. Izi ziyenera kukumbukiridwa, komabe, kuti pansi pa zovuta zazikulu za cyclic alloy P amawonetsa kusintha kokhazikika kokhazikika ndi kuzungulira kulikonse, ndikuyambitsa kofananira.zirokusintha kwa strain gauge. Chifukwa cha chikhalidwe ichi, komanso chizolowezi cholephera kufulumira kwa gridi ndikusefa mobwerezabwereza, P alloy nthawi zambiri samalimbikitsidwa kuti agwiritse ntchito ma cyclic strain. P alloy imapezeka ndi manambala a STC a 08 ndi 40 kuti agwiritsidwe ntchito pazitsulo ndi mapulasitiki, motsatana.

2. Chiyambi cha Spring ndi ntchito

Kasupe wozungulira wozungulira, kapena kasupe, mu wotchi ya alamu.

Kasupe waufulu. Pakanikizidwa ma koyilo amatsetsereka wina ndi mzake, kotero kuti azitha kuyenda nthawi yayitali.

Akasupe osunthika amtundu wa Stuart tank

Kukangana kumayambira mu chipangizo chopindika cholumikizira.

A torsion bar yopindika pansi pa katundu

Kasupe wa masamba pagalimoto
Springs amatha kugawidwa kutengera momwe mphamvu yolemetsa imagwiritsidwira ntchito kwa iwo:

Kuthamanga / kukulitsa kasupe - kasupe amapangidwa kuti azigwira ntchito ndi zovuta, kotero kasupe amatambasula pamene katunduyo akugwiritsidwa ntchito.
Kuponderezana kasupe - kumapangidwira kuti azigwira ntchito ndi katundu woponderezedwa, kotero kuti kasupe amafupikitsa pamene katunduyo akugwiritsidwa ntchito.
Kasupe wa Torsion - mosiyana ndi mitundu yomwe ili pamwambayi yomwe katunduyo ndi mphamvu ya axial, katundu wogwiritsidwa ntchito ku kasupe wa torsion ndi torque kapena mphamvu yokhotakhota, ndipo mapeto a kasupe amazungulira mozungulira pamene katunduyo akugwiritsidwa ntchito.
Kasupe wanthawi zonse - katundu wothandizidwa amakhalabe chimodzimodzi panthawi yonse yopatuka.
Kusintha kasupe - kukana kwa koyilo kuti kulowetse kumasiyanasiyana panthawi ya kupanikizana.
Kuuma kosinthika kwamasika - kukana kwa koyilo kuti kulowetse kumatha kusinthika mosiyanasiyana mwachitsanzo ndi makina owongolera, mitundu ina ya akasupe awa imasiyananso kutalika kwake poperekanso kuthekera koyambitsanso.
Athanso kugawidwa kutengera mawonekedwe awo:

Kasupe wathyathyathya - mtundu uwu umapangidwa ndi chitsulo chosanja chachitsulo.
Kasupe wopangidwa ndi makina - mtundu uwu wa kasupe umapangidwa ndi makina opangira makina omwe ali ndi lathe ndi / kapena mphero m'malo mozungulira. Popeza imapangidwa ndi makina, kasupe amatha kuphatikizira zinthu zina kuwonjezera pa zotanuka. Akasupe opangidwa ndi makina amatha kupangidwa m'machitidwe olemetsa amtundu wa compression / extension, torsion, etc.
Njoka kasupe - zig-zag wa waya wandiweyani - nthawi zambiri amagwiritsidwa ntchito mu upholstery / mipando yamakono.

3.Chemical Composition ndi Main Property ya Cu-Ni Low Resistance Alloy
