1. The quality of the raw materials of the infrared heating tube is not good. Good infrared heating tubes are made of high-quality dehydrogenated quartz tubes.
2. The manufacturing process is not good enough. If the sealing process of the quartz tube is insufficient, air leakage will occur.
3. The design is not up to standard, the power design per meter is too large, and the temperature in the tube is too high, which affects the service life.
4. During the use of the infrared lamp, the temperature of the sealing parts at both ends exceeds 350 degrees, causing the molybdenum sheet at the joint to expand and leak.
5. When using the infrared heating tube, the filament lamp tube is broken due to external impact or excessive vibration of the machine when the equipment is running.
6. The use environment of the infrared heating tube is relatively harsh, and there are many alkaline substances in the medium.
7. The infrared heating tube has no temperature control, which makes it work at the limit allowable temperature for a long time.
8. The connection method is wrong, but it should be a star connection, not a delta connection.
