應(yīng)用:主要用于塑料工業(yè)注塑機(jī)、擠出機(jī)和吹塑機(jī)的加熱,同時(shí)也可用于反應(yīng)釜、熔體管道等化工領(lǐng)域的加熱。
結(jié)構(gòu):采用Ni80Cr20電阻絲插入陶瓷內(nèi)孔,整個(gè)加熱體柔軟可塑,升溫迅速,加熱均勻,節(jié)能及較長(zhǎng)的使用壽命。金屬外殼采用不銹鋼板或鍍鋁鋼板制作。
技術(shù)參數(shù)
陶瓷加熱器-工作溫度可達(dá)760℃,功率密度可高至8w/cm2。陶瓷加熱圈的Z小直徑為40mm,直徑大干600mm時(shí),應(yīng)分成2-8個(gè)弧段加熱,采用壓力彈簧夾緊。加熱器的Z小寬度為18mm,以7.5mm為進(jìn)階(18、25.5、33、40.5、48mm……)Z大寬度不應(yīng)大干500mm,加熱體的厚度為12mm,如需加保溫層,加熱體的厚度會(huì)根據(jù)保溫層厚度增大,請(qǐng)考慮安裝空間。
電源接線方式
1.插頭式接線(最大20A);
2.接線盒式接線(可多相固定連接);
3.高溫線引出式接線(屏蔽耐熱純鎳導(dǎo)線)。
Application
It is mainly applied to heating the plastic injection molding machine, extruding machine and blowing machine. Meantime, it also can be used to heat reaction kettle, melt pipe, etc in chemical industry.
Structure
Ni80Cr20 resistance wire is inserted into ceramic inner hole. The whole heating body is soft & mouldable, energy-saving and durable. Furthermore, it is heated up quickly and evenly. The metal shell is made of stainless steel plate or galvanized steel plate.
Technical Parameter
The working temperature can be up to 760℃ and the power density 8w/cm2. The minimum diameter of ceramic heating ring is 40mm.
When the diameter is larger than 600mm, the ring, clamped by pressure spring, should be separated int0 2-8 segmental arc to be heated. On the other hand, the minimum width of the heater is 18mm and the maximum width of that should not be more than 500mm, increasing by 7.5mm (1 8,25.5,33,40.5,48mm...). The thickness of the heating body is 12mm. If adding thermal insulation layer, the thickness of the heating body increases accordingly. Please take installation space into consideration.
