Spiral Electric Resistor Nicr Alloy 1 – 5 Mohm yeAir Conditioner Heating Elements
1.INkcazelo Jikelele yezinto eziphathekayo
Constantanyingxubevange yobhedu-nickel eyaziwa ngokubaEureka,Phambili, kwayeIsikhitshane. Ngokuqhelekileyo iqulethe i-55% yobhedu kunye ne-nickel ye-45%. Into ephambili yayo yi-resistivity yayo, ehlala ihleli phezu kwamaqondo obushushu amaninzi. Ezinye ii-alloys ezine-coefficients zobushushu obuphantsi ngokufanayo ziyaziwa, njenge-mangan (Cu86Mn12Ni2).
Ngomlinganiselo weentlobo ezinkulu kakhulu, i-5% (50 000 microstrian) okanye ngaphezulu, i-annealed constantan (P alloy) yimathiriyeli yegridi ekhethwa ngokuqhelekileyo. UConstantan kule fomu kakhuluiductile; kwaye, kwi-gauge ubude be-0.125 intshi (3.2 mm) kwaye ubude, bunokuxinzelelwa kwi->20%. Kufuneka kukhunjulwe, nangona kunjalo, ukuba phantsi koxinzelelo oluphezulu lwe-cyclic ingxubevange ye-P iya kubonisa utshintsho olusisigxina lokumelana nomjikelo ngamnye, kwaye ibangele ohambelanayo.unothiutshintsho kwi-strain gauge. Ngenxa yolu phawu, kunye notyekelo lokusilela kwegridi kwangaphambi kwexesha ngoxinzelelo oluphindaphindiweyo, i-P alloy ayiqhelekanga ukucetyiswa kwi-cyclic strain application. I-P alloy ifumaneka ngeenombolo ze-STC ze-08 kunye ne-40 ukuze zisetyenziswe kwiintsimbi kunye neeplastiki, ngokulandelelanayo.
2. Intshayelelo yaseNtwasahlobo kunye nezicelo
Umthombo ojikelezayo we-torsion, okanye i-hairspring, kwiwotshi ye-alarm.
Umthombo ovulekileyo. Ngaphantsi koxinzelelo iikhoyili zityibilika phezu komnye, ukuze zikwazi ukuhamba ixesha elide.
Imithombo yevolute ethe nkqo yetanki yaseStuart
Uxinzelelo luqala kwisixhobo sokuguqula umgca osongiweyo.
I-torsion bar ejijekileyo phantsi komthwalo
Amagqabi aphuma kwilori
Imithombo ingahlelwa ngokuxhomekeke kwindlela amandla omthwalo asetyenziswa ngayo kuwo:
I-Tension / Extension spring - intwasahlobo yenzelwe ukusebenza kunye nomthwalo woxinzelelo, ngoko ke intwasahlobo ilula njengoko umthwalo usetyenziswa kuyo.
Ukunyanzeliswa kwentwasahlobo - yenzelwe ukusebenza kunye nomthwalo woxinzelelo, ngoko ke intwasahlobo iba mfutshane njengoko umthwalo usetyenziswa kuyo.
I-Torsion spring - ngokungafaniyo neentlobo ezingentla apho umthwalo unamandla e-axial, umthwalo osetyenziswa kwi-torsion spring yi-torque okanye i-twist force, kwaye ukuphela kwentwasahlobo kujikeleza nge-angle njengoko umthwalo usetyenziswa.
Intwasahlobo rhoqo - umthwalo oxhaswayo uhlala ufana kuwo wonke umjikelo wokutenxa.
Intwasahlobo eguquguqukayo - ukuchasana kwekhoyili ukulayisha kuyahluka ngexesha loxinzelelo.
Ukuqina okuguquguqukayo kwentwasahlobo - ukuxhathisa kwekhoyili ukulayisha kunokuguquguquka ngokuguquguqukayo ngokomzekelo yinkqubo yokulawula, ezinye iintlobo zale mithombo zinokwahluka ubude bazo ngaloo ndlela zibonelela ngesakhono sokusebenza.
Zisenokwahlulwa ngokwemilo yazo:
I-Flat spring - olu hlobo lwenziwe ngentsimbi ye-flat spring.
Intwasahlobo esetyenzisiweyo - olu hlobo lwentwasahlobo luveliswa yi-machining bar stock kunye ne-lathe kunye / okanye umsebenzi wokugaya kunokuba usebenze ngokudibanisa. Ekubeni isenziwa ngoomatshini, intwasahlobo isenokubandakanya izinto ezongezelelekileyo kwi-elastic element. Imithombo esetyenzisiweyo inokwenziwa kwiimeko eziqhelekileyo zomthwalo woxinzelelo / ulwandiso, ukuxhatshazwa, njl.
Intwasahlobo yasenyoka - i-zig-zag yocingo olungqingqwa - oluhlala lusetyenziswa kwi-upholstery / ifenitshala yanamhlanje.
