Chidziwitso Choyambira Chokhudza Ma heater a Electromagnetic (II)

Mfundo yogwiritsira ntchito chotenthetsera chamagetsi ndi: 220V kapena 380V alternating current, yokonzedwanso kuti ikhale yolunjika, kenako ndikusefedwa mwachindunji.IGBT kapena thyristor amagwiritsidwa ntchito kutembenuza DC kukhala AC kuti apange mizere yamphamvu yamagetsi yamagetsi mu coil induction.Mafunde a Eddy amapangidwa pamwamba pa chopangira chowongolera mu koyilo yolowera, kudalira kukana kodzipangira mkati kuti apange kutentha.

Frequency converter ndiye gawo lalikulu la chotenthetsera chamagetsi chamagetsi chapamwamba kwambiri.Ndi chipangizo chowongolera mphamvu chomwe chimagwiritsa ntchito mphamvu yamagetsi yamagetsi yamagetsi kuti isinthe mphamvu pafupipafupi yamagetsi kukhala ma frequency ena.Pakadali pano, chosinthira pafupipafupi chomwe chimagwiritsidwa ntchito makamaka chimagwiritsa ntchito mawonekedwe a AC-DC-AC, choyamba kutembenuza ma frequency amagetsi a AC kukhala magetsi a DC kudzera pa rectifier, kenako ndikusintha magetsi a DC kukhala magetsi a AC omwe amatha kuwongolera pafupipafupi komanso voteji kuti apereke injini.

Njira yotenthetsera mphete ndikusamutsa kutentha ku mbiya polumikizana ndi conduction.Kutentha kokha komwe kuli pafupi ndi mkati mwa mbiya kungathe kusamutsidwa ku mbiya, kotero kuti kutentha kwakukulu kunja kumatayika mlengalenga, kutayika kwa kayendedwe ka kutentha, ndipo kutentha kozungulira kumakwera.Kuphatikiza apo, kutentha kwa waya kumakhalanso ndi vuto loti kuchulukitsitsa kwamagetsi kumakhala kochepa, ndipo sikungasinthidwe munyengo zina zotentha zomwe zimafuna kutentha kwambiri.Tekinoloje yotenthetsera yamagetsi ndi kudzera mu mfundo ya kulowetsedwa kwamagetsi kuti mbiya yachitsulo ikhale yotentha, ndipo imatha kukutidwa ndi makulidwe ena azinthu zotenthetsera kunja kwa mbiya molingana ndi momwe zimakhalira, zomwe zimachepetsa kwambiri kutayika kwa kutentha, kumapangitsa kuti kutentha kumatenthedwe. , kotero mphamvu yopulumutsa mphamvu ndi yofunika kwambiri, mpaka 30% ~ 75%.Chifukwa mphete yotenthetsera yamagetsi yokhayo sipanga kutentha, ndipo imapangidwa ndi zida zotchingira ndi zingwe zotentha kwambiri, palibe vuto kuti waya wotsutsa wa mphete yoyambira yotenthetsera amathira oxidize kutentha kwambiri ndikufupikitsa moyo wautumiki.Ili ndi ubwino wa moyo wautali wautumiki, kutentha kwachangu, ndipo palibe chifukwa chokonzekera, zomwe zimachepetsa nthawi yokonza ndi ndalama.Tsopano yakhala ikugwiritsidwa ntchito ndi mabizinesi ambiri apulasitiki, kuchepetsa kwambiri mtengo wopangira mabizinesi.

Thepulasitiki extrusion makinazopangidwa ndi Laizhou Kaihui Machinery Co., Ltd. ndi oyenera mitundu yosiyanasiyana ya chotenthetsera magetsi.Tikhoza amalangiza malinga ndi zosowa kasitomala.Takulandilani kuti mulumikizane nafe kuti mudziwe zambiri
