Tube heater
Chimiro chemukati chechubhu chinopisa chakafanana neicho checartridge heater.Misiyano yaro huru kubva kune cartridge heaters ndeyokuti zvigaro zvinotungamirira zvinowanikwa kumativi ose maviri echubhu.Iyo yese tubular dhizaini inogona kukoneswa kuita akasiyana mafomu kuti aenderane neinodiwa kupisa kugovera kwenzvimbo kana nzvimbo yekupisa.Pamusoro pezvo, maheater aya anogona kuve nemafins akasungirirwa pamusoro pe sheath kuti abatsire mukufambiswa kwekushisa kwakanaka.Tubular heaters anongo siyana-siyana sema cartridge heaters uye anoshandiswa mumashandisirwo akafanana.
Band Heaters
Maheater aya akagadzirwa kuti aputire cylindrical metal surfaces kana midziyo yakaita sepombi, mbiya, madhiramu, extruder, etc. Ane mabhaudhi-pa cleats anocheka zvakachengetedzeka kune Container surface.Mukati mebhanhire, hita iwaya yakaonda inodzivirira kana bhandi, kazhinji yakavharidzirwa nekaseti ye mica.Sheaths inogadzirwa nesimbi isina tsvina kana ndarira.Imwe mukana wekushandisa bhandi hita ndeyekuti inogona kupisa zvisina kunanga mvura mukati memudziyo.Izvi zvinoreva kuti hita haisi pasi pekurwiswa kwekemikari kubva kumvura yekuita.Zvakare inodzivirira kubva kumoto unobvira kana uchishandiswa mumafuta uye sevhisi yekuzora.
Strip Heater
Rudzi urwu rwekupisa rune chimiro chakati sandara, chine rectangular uye chakasungirirwa pamusoro kuti chidziswe.Chimiro chayo chemukati chakafanana nebhandi heater.Nekudaro, insulating zvinhu kunze kwe mica inogona kunge iri ceramics senge magnesium oxide uye girazi fibers.Mashandisirwo ezvidziidzo zvemitsetse kudziya kwepasi kwe mold, mold, maplatens, matangi, pombi, nezvimwewo. Pamusoro pekudziya kwepamusoro, anogona kushandiswawo kupisa mhepo kana mvura nekuve nefinned surface.Mafinha anopisa anoonekwa mumahovhoni uye munzvimbo dzinopisa.
Ceramic Heaters
Maheater aya anoshandisa maceramics ane nzvimbo yakanyanyisa kunyunguduka, kugadzikana kwekushisa kwepamusoro, kusimba kwekushisa kwepamusoro, kukwirira kwemakemikari inertness, uye diki yekupisa.Ziva kuti izvi hazvina kufanana nekeramics inoshandiswa se insulating zvinhu.Nekuda kweiyo yakanaka yekupisa conductivity, inoshandiswa kuitisa uye kugovera kupisa kubva kune inopisa chinhu.Zvinozivikanwa zveceramic heaters isilicon nitride uye aluminium nitride.Izvi zvinowanzo shandiswa kupisa nekukurumidza, sezvinoonekwa pamapulagi anopenya uye anodzima.Nekudaro, kana ichiiswa pasi pekukurumidza-yepamusoro-tembiricha yekudziya uye kutonhora kutenderera, zvinhu zvacho zvinogara zvichitsemuka nekuda kwekupisa kwekushushikana-kunokonzerwa kuneta.Rudzi rwakakosha rweceramic hita iPTC ceramic.Rudzi urwu runozvigadzirisa simba rayo, izvo zvinodzivirira kubva pakutsvuka.
