Waya wa Karmandi waya wa aloyi wa nickel-chromium-aluminium-iron wogwira ntchito kwambiri, womwe umagwiritsidwa ntchito kwambiri ngati chinthu chachikulu chogwiritsira ntchito zotsutsana molondola komanso zida zoyezera.

Kukana kwake bwino kwambiri, kukana kutentha kochepa (TCR), komanso magwiridwe antchito okhazikika zimapangitsa kuti ikhale yosasinthika mumakampani olondola. Bukuli limathandiza akatswiri pantchito yolimbana ndi zolondola komanso zida zoyezera kusankha waya woyenera wa Karma pamapulojekiti awo.

1. Chifukwa Chake Waya wa Karma Ndi Wofunika Kwambiri pa Zotsutsa Zolondola & Zida Zoyezera

1.1 Ubwino Waukulu wa Mapulogalamu Olondola

Waya wa Karma umadziwika bwino kwambiri mumakampani olondola chifukwa cha mawonekedwe ake apadera:

- Kukana kwakukulu (1.33 μΩ·m pa 20℃), kokwera nthawi 2-3 kuposa manganin, zomwe zimathandiza mapangidwe a resistor yaying'ono.

- TCR yotsika kwambiri (±20 ppm/℃), kuonetsetsa kuti kutentha kumakhala kolimba.

- Kutentha kochepa kwa EMF poyerekeza ndi mkuwa (≤2.5 μV/℃), kuchepetsa zolakwika muyeso mu zida zolondola.

1.2 Udindo Wofunika Kwambiri pa Zochitika Zofunika Kwambiri

Ndi chinthu chomwe chimakonda kwambiri kugwiritsa ntchito ma resistors a waya olondola kwambiri, ma strain gauges, ndi masensa oyezera.

Kukhazikika kwake kumatsimikizira mwachindunji kulondola ndi kudalirika kwa zida m'magawo oyezera ndege, zamankhwala, ndi mafakitale.

2. Zinthu Zofunika Kuziganizira Posankha Waya wa Karma

2.1 Kapangidwe ka Mankhwala ndi Giredi

Giredi yokhazikika yogwiritsira ntchito molondola ndi Karma 6J22, yokhala ndi kapangidwe kowongoleredwa bwino:

- Nikeli (Ni): Kuchuluka (pafupifupi 75%), Chromium (Cr): 19-21%, Aluminiyamu (Al): 2.5-3.2%, Iron (Fe): 2.0-3.0%.

Zinthu zotsatizana (Si, Mn, C) zimachepetsedwa kufika pa ≤0.5% kuti zitsimikizire kuti ntchito yake ndi yokhazikika.

2.2 Waya m'mimba mwake & Kulekerera

Kukula kwake kumakhudza mwachindunji kulondola kwa kukana ndi kuthekera kokonza:

- Kwa zotsutsa zolondola: 0.018mm-0.10mm (m'mimba mwake waung'ono wa mapangidwe ang'onoang'ono).

- Kwa masensa oyezera: 0.10mm-0.50mm (kulinganiza kusinthasintha ndi kukhazikika).

Kulekerera kuyenera kukhala ≤±0.003mm pa ntchito zofunika kwambiri kuti tipewe kusinthasintha kwa kukana.

2.3 Chithandizo cha Pamwamba

Mankhwala awiri ofanana pamwamba alipo pa zosowa zosiyanasiyana:

- Malo owala: Opukutidwa bwino, abwino kwambiri pakugwiritsa ntchito omwe amafunikira kusungunuka bwino komanso mawonekedwe okongola.

- Malo osungunuka: Filimu yolimba yoteteza, yolimbikitsa kukana okosijeni komanso kukhazikika kwa nthawi yayitali kutentha kwambiri.

2.4 Kusinthasintha kwa Kutentha

Sankhani kutengera kutentha kwa zida zanu:

- Kugwiritsa ntchito mosasunthika: Mpaka 400℃, koyenera kugwiritsa ntchito zotsutsa zolondola.

- Kugwiritsa ntchito mphamvu: Kufikira 800℃, koyenera kwambiri poyesa kutentha kwambiri.

3. Waya wa Karma vs. Mawaya Ofanana a Alloy: Kuyerekeza kwa Makampani Olondola

Gome ili m'munsimu likuthandizani kusiyanitsa waya wa Karma ndi constantan (njira yodziwika bwino) yogwiritsira ntchito molondola:

4. Buku Lotsogolera Gawo ndi Gawo Losankha Waya wa Karma pa Ntchito Yanu

Gawo 1: Fotokozani Zofunikira pa Kugwiritsa Ntchito

Fotokozani mtundu wa chida (chotsutsa molondola, choyezera kupsinjika, sensa) ndi malo ogwirira ntchito (kutentha, chinyezi).

Mwachitsanzo, ma gauge oyezera mphamvu m'malo otentha pang'ono (-269℃ mpaka 300℃) amaika patsogolo waya wa Karma kuti kutentha kwake kukhale kokhazikika.

Gawo 2: Dziwani Zofunikira

Sankhani kukula kwake, kulekerera kwake, ndi kalasi yake kutengera mphamvu ya kukana kwake komanso malo oyika.

Pa zotsutsa zazing'ono zolondola, sankhani mainchesi a 0.02mm-0.05mm okhala ndi kulekerera kwa ±0.001mm.

Gawo 3: Sankhani Chithandizo Chapamwamba

Sankhani malo owala ngati pakufunika kusungunula; sankhani malo okosijeni kuti mugwiritse ntchito kutentha kwambiri kapena kwa nthawi yayitali.

Pa magauji oyezera kupsinjika, ma naked solder pads (SP) amalimbikitsidwa kuti azitha kusinthasintha, pomwe ma tinned dots (SD) amathandizanso kusungunula.

Gawo 4: Tsimikizirani Ubwino ndi Miyezo

Onetsetsani kuti wayayo ikutsatira miyezo ya ASTM B267 ndi JB/T 5328 kuti igwire ntchito bwino nthawi zonse.

Yang'anani mayeso 100% asanafike nthawi yobereka (kukana, TCR, kulolerana ndi dayamita) kuti mupewe mavuto a khalidwe.

5. Waya Wathu wa Karma: Wopangidwira Zotsutsa Zolondola ndi Zida Zoyezera

5.1 Mafotokozedwe Athunthu

Timapereka waya wa Karma 6J22 wokhala ndi mainchesi kuyambira 0.018mm mpaka 1.50mm, zomwe zikugwirizana ndi zosowa zonse zamakampani.

Zosankha zololera zimayambira pa ± 0.001mm mpaka ± 0.03mm, zomwe zimatsimikizira kulondola kwamphamvu.

5.2 Mayankho Opangidwa Mwamakonda

Perekani chithandizo chapamwamba chomwe chimakonzedwa mwamakonda (chowala/chosungunuka) ndi kutalika kwa kudula kwa mapangidwe a zida zinazake.

Konzani pang'ono kapangidwe ka alloy kuti muchepetse kutentha kwanu (STC) kuti mugwirizane ndi ma coefficients okulitsa zinthu zoyeserera.

5.3 Kulamulira Kwabwino Kwambiri

Kupanga kosungunuka ndi vacuum kumatsimikizira kuyera kwambiri (>99.5%) ndi magwiridwe antchito ofanana.

Kuyesa 100% musanaperekedwe kumaphatikizapo kukana, TCR, kutentha kwa EMF, ndi kuwunika kwa mainchesi kuti zikwaniritse miyezo yolondola yamakampani.

6. Mapeto

Kusankha waya woyenera wa Karma ndikofunikira kwambiri pa kulondola ndi kudalirika kwa zotsutsa zolondola ndi zida zoyezera.

Mwa kuyang'ana kwambiri kapangidwe kake, kukula kwake, kukonza pamwamba, komanso kusinthasintha kwa kutentha, mutha kusankha waya woyenera kwambiri pa ntchito yanu.

Waya wathu wa Karma wapamwamba kwambiri, wopangidwira makampani olondola, umapereka mayankho okhazikika komanso odalirika.Lumikizanani nafekuti mupeze malangizo ogwirizana ndi zosowa zanu kutengera zomwe mukufuna pa chipangizo chanu.
