Electromagnetic induction heating technology-a power saving principle chu metal heated body heat ngei siam a ni a, dinhmun bik ang chuan heat insulation material engemaw zat chu heating body pawnah a inkhuh thei a, hei hian heat loss nasa takin a ti tlem a, thermal efficiency a ti tha hle a, chuvangin power saving effect chu a pawimawh hle a, 30% thlengin 80% thlengin a tisang thei a ni.
1. Heating method awmsa te insufficiency .
Hetiang dinhmunah hian plastic machinery ang chi heating equipment hmanga heating method hman chu a tlangpuiin electric heating coil a ni a, chu chuan contact conduction hmangin heated body-ah lumna a transfer a, mahse barrel chunglam hnaih ber lumna chauh a tha zawk ang. Taksa lum takah a kai chuan pawn lama lumna tam zawk chu boruakah a bo a, heat conduction hloh a awm a, chu chuan boruak lumna a tisang a ni. Chu bakah, resistance wire heating hian power density hniam tak a tichhe a, hei hi hun engemaw chen chu temperature sang zawk mamawh a ni. Lungawi.
2. Power Saving Principle .
Electromagnetic heating system hi hmun hnih a awm a, chungte chu electromagnetic heating control board leh heating coil te an ni. Machine original-a temperature-controlled power supply [heating output contactor (or solid-state relay) output terminal] chuan power-frequency AC power chu electromagnetic heating control board kaltlangin high-frequency AC power-ah a rectified a, a filter a, a invert a, connecting wire kaltlangin electromagnetic heating coil-ah a connect a ni. High-frequency alternating current hian metal lum tak tak taksaah insulation material hmangin a thawk a, chu chuan taksa lum tak chu a lum phah a ni. Chu bakah, power supply chu electromagnetic heating control board-ah direct-a input theih a ni bawk a, original temperature controller chuan electromagnetic heating controller-a soft start interface hmangin electromagnetic heating control board hnathawh dan chu direct-in a control thei bawk.
He heating method thatna pakhat chu hmanrua hi hun rei tak chhung tihhlum a ngai lo va, engtik lai pawha tan emaw tihtawp emaw theih a ni a, set heating temperature thleng tur chuan second sawm aia tam chauh a ngai a ni.
Induction hi non-contact heating method a nih avangin coil hian engtik lai pawhin workpiece hi a khawih tak tak ngai lo tih hre reng ang che.
Eddy current te hian anmahni magnetic field an siam a, chu chuan coil atanga lo chhuak original magnetic field chu a dodal a ni. He dodalna hian original magnetic field chu coil-in a hual vel thil lairil lamah a luh nghal theih loh nan a veng a ni.
Eddy currents hi thil tih lum tur chunglam hnaih ber a ni a, mahse a lai lam hawiin a chak lo zawk hle.
Thil lum chunglam atanga current density 37% thlenga a tlakna thuk zawng chu penetration depth a ni. He depth hi frequency tlahniam nen a sang chho zel a ni. Chuvangin, penetration depth duh ang ang chu a thlen theih nan frequency dik tak thlan a ngai a ni.
Chumi Off-line rotary pipe induction heating system siamchhuahna line chu mahni inrintawkna neia siam a ni. Hangao Tech (Seko Machinery) hi test a ni tawh a, 50% thlengin energy a humhim thei a ni. A siam chhuah zawng zawngah hian automatic feeding-front leh rear tube speed synchronization-induction heating-water cooling-automatic unloading a huam a ni. He hmanrua hi customer-in order a mamawh bik angin a siam a, caliber range pawh 219 atanga 1219mm inkar a handle thei bawk. Pipe chu rotating rollers hmanga kah a ni a, chu chuan a lum hnua a thil tih a nem avangin large-diameter steel pipe a chim leh a tlakchhiat loh nan a veng a, secondary straightening chungchanga harsatna a chinfel sak bawk. He hmanrua hi domestic leading pipe manufacturing enterprise tam takah hman a ni tawh a, market-in a finfiah kim tawh bawk.
