I-Spiral Electric Resistor Nicr Alloy 1 – 5 Mohm Yezinto Zokushisisa I-Air Conditioner
1.Incazelo Yezinto Ezivamile
Constantaniyingxubevange yethusi-nickel eyaziwa nangokuthiEureka,Phambili, futhiIsikebhe. Ngokuvamile iqukethe u-55% wethusi no-45% we-nickel. Isici saso esiyinhloko yi-resistivity yayo, ehlala njalo phezu kwezinhlobonhlobo zamazinga okushisa. Amanye ama-alloy anama-coefficients okushisa aphansi afanayo ayaziwa, njenge-mangan (Cu86Mn12Ni2).
Esilinganisweni sezinhlobo ezinkulu kakhulu, u-5% (50 000 microstrian) noma ngaphezulu, i-annealed constantan (P alloy) iwumsebenzi wegridi ovame ukukhethwa. Constantan kuleli fomu kakhului-ductile; futhi, ku-gauge yobude obungu-0.125 amayintshi (3.2 mm) nangaphezulu, ingacindezelwa ibe ngu->20%. Kufanele kukhunjulwe, nokho, ukuthi ngaphansi kwezinhlobo eziphakeme zama-cyclic i-P ingxubevange izokhombisa ushintsho oluthile lokumelana okungapheli ngomjikelezo ngamunye, futhi ibangele okuhambisanayo.uziroukushintsha kwe-strain gauge. Ngenxa yalesi sici, kanye nokuthambekela kokwehluleka kwegridi ngaphambi kwesikhathi ngokuqina okuphindaphindiwe, i-P alloy ayinconywa ngokujwayelekile ezinhlelweni zohlobo lwe-cyclic. I-P ingxubevange iyatholakala nezinombolo ze-STC zika-08 no-40 ukuze zisetshenziswe ezinsimbi namapulasitiki, ngokulandelana.
2. Isingeniso Sentwasahlobo kanye nezicelo
Isiphethu se-torsion spiral, noma i-hairspring, ewashini le-alamu.
Intwasahlobo evulekile. Ngaphansi kokucindezelwa amakhoyili ayashelela phezu kwelinye, ukuze akwazi ukuhamba isikhathi eside.
Iziphethu zevolute eziqondile ze-Stuart tank
Ukushuba kuqhamuka emshinini ogoqiwe wokuguqula umugqa.
I-torsion bar esontekile ngaphansi komthwalo
Iqabunga liphuma elolini
Iziphethu zingahlukaniswa kuye ngokuthi amandla omthwalo asetshenziswa kanjani kuzo:
I-Tension/extension spring - intwasahlobo iklanyelwe ukusebenza ngomthwalo we-tension, ngakho-ke intwasahlobo iyanwebeka njengoba umthwalo usetshenziswa kuwo.
Intwasahlobo yokucindezela - iklanyelwe ukusebenza ngomthwalo wokucindezela, ngakho-ke intwasahlobo iba mfushane njengoba umthwalo usetshenziswa kuwo.
I-Torsion spring - ngokungafani nezinhlobo ezingenhla lapho umthwalo ungamandla e-axial, umthwalo osetshenziswa emthonjeni we-torsion uyi-torque noma amandla aphikisayo, futhi ukuphela kwentwasahlobo kujikeleza nge-angle njengoba umthwalo usetshenziswa.
Intwasahlobo eqhubekayo - umthwalo osekelwayo uhlala unjalo kuwo wonke umjikelezo wokuchezuka.
Intwasahlobo eguquguqukayo - ukumelana kwekhoyili ukulayisha kuyahlukahluka ngesikhathi sokucindezelwa.
Ukuqina okuguquguqukayo kwentwasahlobo - ukumelana kwekhoyili ukulayisha kungashintshashintsha ngokwesibonelo ngohlelo lokulawula, ezinye izinhlobo zalezi ziphethu ziyashintsha ubude bazo ngaleyo ndlela zinikeze amandla okucupha futhi.
Futhi zingahlukaniswa ngokuya ngesimo sazo:
Intwasahlobo eyisicaba - lolu hlobo lwenziwe ngensimbi eyisicaba.
Intwasahlobo eyenziwe ngomshini - lolu hlobo lwentwasahlobo lukhiqizwa isitokwe sebha yomshini nge-lathe kanye/noma umsebenzi wokugaya esikhundleni sokusebenza kokugoqa. Njengoba yenziwe ngomshini, intwasahlobo ingase ihlanganise izici ngaphezu kwesici esinwebekayo. Iziphethu ezenziwe ngomshini zingenziwa ezimweni ezijwayelekile zokulayisha zokucindezelwa/isandiso, ukukhwehlela, njll.
Intwasahlobo yenyoka - i-zig-zag yocingo oluwugqinsi - evame ukusetshenziswa ku-upholstery/ifenisha yesimanje.
