Njira yogwiritsira ntchito chitetezo cha overheat

Njira yolondola yogwiritsira ntchito choteteza kutentha kwambiri (kusintha kwa kutentha) kumakhudza mwachindunji chitetezo ndi chitetezo cha zida. Zotsatirazi ndizofotokozera mwatsatanetsatane kukhazikitsa, kutumiza ndi kukonza:
I. Njira Yoyikira
1. Kusankha malo
Kulumikizana kwachindunji ndi komwe kumachokera kutentha: Kumayikidwa m'malo omwe nthawi zambiri kumapangitsa kutentha (monga ma windings a motor motor, ma thiransifoma, ndi pamwamba pa masinki otentha).
Pewani kupsinjika kwamakina: Khalani kutali ndi malo omwe nthawi zambiri amanjenjemera kapena kukakamizidwa kuti mupewe kusokoneza.
Kusintha kwa chilengedwe
Malo achinyezi: Sankhani mitundu yopanda madzi (monga mtundu wosindikizidwa wa ST22).
Malo otentha kwambiri: Casing yosagwira kutentha (monga KLIXON 8CM imatha kupirira kutentha kwanthawi yayitali 200 ° C).
2. Njira yokhazikika
Mtundu womangidwa m'mitolo: Wokhazikika ku zigawo za cylindrical (monga ma coil agalimoto) okhala ndi zomangira zachitsulo.
Ophatikizidwa: Lowetsani mu kagawo kosungidwa kachipangizo (monga kagawo kosindikizidwa ndi pulasitiki ka chotenthetsera madzi chamagetsi).
Screw fixation: Mitundu ina yapamwamba kwambiri iyenera kumangirizidwa ndi zomangira (monga zoteteza 30A).
3. Kufotokozera kwa waya
Zotsatizana mozungulira: Zolumikizidwa ku dera lalikulu kapena kuwongolera kuzungulira (monga chingwe chamagetsi chamoto).
Chidziwitso cha Polarity: Oteteza ena a DC ayenera kusiyanitsa pakati pa mitengo yabwino ndi yoyipa (monga mndandanda wa 6AP1).
Kufotokozera kwawaya: Fananizani ndi katundu wapano (mwachitsanzo, katundu wa 10A amafuna ≥1.5mm² waya).
Ii. Kuthetsa zolakwika ndi Kuyesa
1. Kutsimikizira kutentha kwa zochita
Gwiritsani ntchito gwero la kutentha kosasinthasintha (monga mfuti ya mpweya wotentha) kuti muwonjezere kutentha pang'onopang'ono, ndikugwiritsa ntchito makina owerengera kuti muwone ngati mukuzimitsa.
Fananizani mtengo wadzina (mwachitsanzo, mtengo wa KSD301 ndi 100°C±5°C) kuti mutsimikize ngati kutentha kwenikweni kogwirira ntchito kuli mkati mwa kulekerera.
2. Bwezerani kuyesa ntchito
Mtundu wodzikhazikitsanso: Iyenera kubwezeretsanso ma conduction pambuyo pozizira (monga ST22).
Mtundu wokhazikitsanso pamanja: Batani lokhazikitsiranso likufunika kukanidwa (mwachitsanzo, 6AP1 ikuyenera kuyambitsidwa ndi ndodo yotsekereza).
3. Kuyesa katundu
Mukayatsa, yerekezerani zochulukira (monga kutsekeka kwa mota) ndikuwona ngati wotetezayo amadula dera munthawi yake.
Iii. Kukonza Tsiku ndi Tsiku
1. Kuyendera nthawi zonse
Yang'anani ngati zolumikizanazo ndi oxidized kamodzi pamwezi (makamaka m'malo okhala ndi chinyezi chambiri).
Onani ngati zomangira zili zotayirira (zimakonda kusuntha pamalo onjenjemera).
2. Kuthetsa mavuto
Palibe chochita: Zitha kukhala chifukwa cha ukalamba kapena sintering ndipo ziyenera kusinthidwa.
Zochita zabodza: Onani ngati malo oyikapo asokonezedwa ndi kutentha kwakunja.
3. Sinthani muyezo
Kupitilira kuchuluka kwa zochita (monga mizungu 10,000).
Chophimbacho ndi chopunduka kapena kukana kukhudzana kumawonjezeka kwambiri (kuyezedwa ndi multimeter, nthawi zambiri kumayenera kukhala kuchepera 0.1Ω).
Iv. Chitetezo
1. Ndizoletsedwa kugwiritsa ntchito kupitirira zomwe zatchulidwa
Mwachitsanzo: oteteza omwe ali ndi mphamvu yamagetsi ya 5A/250V sangathe kugwiritsidwa ntchito m'mabwalo a 30A.
2. Osafupikitsa chitetezo
Kudumpha chitetezo kwakanthawi kumatha kupangitsa kuti zida zithe.
3. Chitetezo chapadera cha chilengedwe
Kwa zomera za mankhwala, zitsanzo zotsutsana ndi dzimbiri (monga zitsulo zosapanga dzimbiri) ziyenera kusankhidwa.
Zindikirani: Pakhoza kukhala kusiyana pang'ono pakati pa mitundu ndi mitundu yosiyanasiyana. Onetsetsani kuti mwatchula bukhu laumisiri la mankhwala enieni. Ngati ikugwiritsidwa ntchito pazida zofunika kwambiri (monga zachipatala kapena zankhondo), tikulimbikitsidwa kuti tiziyimitsa pafupipafupi kapena kugwiritsa ntchito njira zodzitetezera zosafunikira.
