Kutulutsa ng’anjo Madzi ozizira chingwe

Chingwe choziziritsa madzi chopangira ng’anjo yotenthetsera induction ndi chingwe chapadera cholumikizira mphamvu yapakati pafupipafupi ndi coil induction. Chifukwa cha kuzizira kwa madzi mkati mwake, amatchedwa chingwe choziziritsa madzi. Ngakhale chingwe choziziritsa madzi chopangira ng’anjo yotenthetsera chimanyamulanso zamakono, mawonekedwe ake amkati ndi osiyana ndi zingwe wamba.

1. Kapangidwe ka chingwe choziziritsidwa ndi madzi cha ng’anjo yotenthetsera:

Chingwe choziziritsa madzi cha ng’anjo yotenthetsera yotenthetsera chimapangidwa ndi maelekitirodi, mawaya amkuwa, mawaya otsekereza, ma nozzles amadzi, ziboliboli zazitsulo zosapanga dzimbiri, etc. Elekitirodi imapangidwa kuchokera ku ndodo zamkuwa zofiira ndikulumikizidwa ndi waya wokhazikika wamkuwa kuti uzizizira. The insulating mphira chubu ndi manja kunja kwa mkuwa stranded waya ndi anamanga pa electrode ndi hoop mmero. Mphuno yamadzi imayikidwa pa electrode, ndipo madzi ozizira amadutsa m’madzi pa electrode. Nozzle amalowa mkati mwa insulating mphira chubu kuziziritsa mkuwa stranded waya kukwaniritsa cholinga overcurrent.

2. Chingwe chozizira ndi madzi chopangira ng’anjo yotenthetsera ‍Standard:

Chingwe choziziritsa madzi cha ng’anjo yotenthetsera induction chikuyenera kutsatira muyezo wa JB/T10358-2002 “Chingwe choziziritsa madzi cha Industrial Electric Heating Equipment”.

3. Mafotokozedwe a zingwe zoziziritsidwa ndi madzi zopangira ng’anjo zotenthetsera:

3.1. Chigawo chamtanda cha chingwe choziziritsa madzi cha ng’anjo yotenthetsera induction chiri pamtunda wa 25 mpaka 500 masikweya millimeters, ndipo kutalika kwake kuli pakati pa 0.3 mpaka 20 metres. Pamene gawo la mtanda silikwanira, maulendo angapo ofanana amagwiritsidwa ntchito nthawi zambiri. Pamene chingwe chokhazikika chamadzi chimakhala chotalika kwambiri, chimagwirizananso ndi muyezo, koma kutaya pamene kulimbikitsidwa kudzakhala kwakukulu kwambiri, komwe sikumakwaniritsa zofunikira zopulumutsa mphamvu.

3.2. Chubu cha rabara ya jekete yotsekera yachingwe choziziritsa madzi cha ng’anjo yotenthetsera yotenthetsera imapangidwa ndi chubu la rabara lapamwamba la kaboni, lokhala ndi kukana kwamadzi kwa 0.8MPa ndi voteji yosweka osakwana 3000V. Zofunikira zapadera ziyenera kugwiritsa ntchito manja a payipi osayaka moto.

3.3. Ma electrode a zingwe zoziziritsa m’madzi zopangira ng’anjo zotenthetsera zotenthetsera amapangidwa ndi mkuwa wa T2, ndipo mulingo wosankhidwa umatanthawuza JB/T10358-2002 “Mazingwe Oziziritsa M’madzi a Zida Zamagetsi Zotenthetsera Magetsi”

3.4. Zingwe zoziziritsidwa ndi madzi zopangira ng’anjo zotenthetsera zotenthetsera zimakhala ndi zofunika kwambiri pamtundu wamadzi ozizira kuti zitsimikizire kuzizira komanso moyo wa zingwe zoziziritsa madzi.

3. 5. Waya wachitsulo wamkuwa wa chingwe choziziritsa madzi cha ng’anjo yotenthetsera yotenthetsera amadulidwa kuchokera ku zingwe zingapo za waya wamkuwa. Kuchuluka kwa zingwe za waya wa mkuwa kumapangitsa kuti chingwe choziziritsa madzi chikhale chofewa, ndipo mtengo wake umakwera.

3.6. Kumangirira kwa chotchinga chakunja cha electrode cha chingwe choziziritsa ndi madzi cha ng’anjo yotenthetsera, hoop yopangidwa ndi 1Cr18Ni9Ti (non-magnetic stainless steel) imagwiritsidwa ntchito kwambiri.
