铸铝电加热器挤出机加热圈注意事项：

工作电压不得超过额定值的10%；

接线部分放在加热层、保温层以外，外壳应有效接地；

应放在干燥处、若因长期放置，绝缘电阻低于1MΩ时，可在摄氏200度左右的烘箱中烘烤5-6小时，即可恢复正常。

应做好定位固定,有效发热区必须与受热体紧密贴合，严禁空烧。发现表面有灰尘或污染物时，应及时清除干净再用，以免影晌散heat而缩短使用寿命。

电hot元件出线端的氧化镁粉，在使用场所避免受到污染物与水分渗入，防止漏电事故的发生。

简介：

是以管状electric为发heat体，用优质铸材料为外壳经压铸成型的electric heat器，其使用温度一般在摄氏150～350度之间，可广泛应用于塑料机械、模头、electric cable机械、化工、橡胶、石油等设备上。铸aluminum heat器特点具有长寿命、高保温性能强力耐腐蚀抗磁场等优点。在addition to the body of the heater on cast cooling pipe, can be used with water cooling device, internal and external add cast cooling fins and radiation plate, can use air cooling device.

防爆heater标志为ExdⅡBT4 ExDⅡBT6 ExdeⅡCT6等。一种高效thermal division uniform heater thermal conductivity excellent metal alloy ensures temperature distribution uniform eliminates equipment hot spots cold points. Long life good insulation strength corrosion resistance magnetic field resistance. External heat dissipation surface added insulation devices internal radiative heating line thus saving electricity 35%.

主要use:

广泛应用于塑料 machinery molds electric cable machinery alloys pressure molding machines pipes chemical rubber petroleum etc.

1., aluminum copper heaters: pouring molten aluminum or copper into a mold containing an electric heating element to create various shapes of heaters. Mainly for plastic machinery ovens water heaters pipes and non-corrosive liquids.

2., iron heaters: pouring molten iron into a mold containing an electric heating element for widespread use in lock chain hardware toys etc.

3., various special requirements for electric heating components: custom-made according to customer needs.

The structure is advanced high efficiency even distribution when high-temperature resistors are heated through crystalline magnesium oxide powder evenly distributed within non-perforated stainless steel tubing filling dense insulating performance magnesium oxide powder around resistors spreading heat through crystalline magnesium oxide powder to metal tubing surfaces then transmitted to heated objects or air achieving desired heating.

1., work voltage not exceeding rated value by 10%; relative humidity less than 95% no corrosive gases.

2., wiring part placed outside the heater layer insulation layer shell must be effectively grounded; avoid contact with corrosive fluids moisture; wire leads able withstand long-term temperatures loads connections tightened without excessive force

3., metal casting heater must do positioning fixation effective heating area must closely adhere to heated object forbidden open burning found surface dust contamination should promptly clean before reuse prevent overheating reduce lifespan

4.. Electric outlet ends' oxidation at usage site avoid pollution contaminants infiltration preventing leakage accidents
