Performance characteristics of quartz heating tubes

Performance characteristics of quartz heating tubes

Firstly, quartz heating tubes have high temperature resistance, corrosion resistance, fast heating, and small thermal inertia. In addition, the thermochemical properties of these devices are also very stable, and their service life is as long as that of stainless steel electric heating tubes, with excellent insulation strength.

Secondly, the quartz heating tube has a high working temperature, with a maximum temperature resistance of 800 ℃ and a relatively wide selection range.

Thirdly, there is no need for far-infrared coatings, which have good absorption characteristics. After long-term use, the radiation performance will not deteriorate, and it has extremely high efficiency in electric heating conversion.

Fourthly, it will not cause any pollution during use and is a product that conforms to the modern concept of environmental protection and energy conservation in daily life.

Fifth, the overall manufacturing and installation process of quartz heating tubes is very convenient and fast, and they are also relatively stable and safe for later use.

How to use electric heating tubes more effectively and safely, not only in terms of quality, but also in a more rational way when using electric heating tubes. Reasonable use can increase the service life of electric heating tubes, improve their operation, and ensure work quality.

The storage location of the electric heating tube is the same as that of components such as platinum rhodium thermocouples, and it must be kept dry and with appropriate insulation resistance. If the insulation resistance of the electric heating tube in the storage environment is found to be too low during use, it can be restored at low voltage before use. Electric heating pipes should be properly fixed before use, and the wiring should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and water.

1. The electric heating tube should be properly positioned and fixed, and the effective heating area must be fully immersed in liquid or metal solids, and empty burning is strictly prohibited. When scale or carbon deposits are found on the surface of the tube, they should be promptly removed and reused to avoid affecting heat dissipation and shortening its service life.

2. The component is allowed to operate under the following conditions:

A. The relative humidity of the air shall not exceed 95%, and there shall be no explosive or corrosive gases.

B. The working voltage should not exceed 1.1 times the rated value, and the casing should be effectively grounded.

C. Insulation resistance ≥ 1M Ω Dielectric strength: 2KV/1min.

3. The magnesium oxide powder at the outlet of the electric heating tube should be protected from pollutants and moisture infiltration in the use site to prevent leakage accidents.

4. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and moisture; The lead wire should be able to withstand the temperature and heating load of the wiring section for a long time, and excessive force should be avoided when tightening the wiring screws.

Before the electric furnace wire, the sensitivity of the temperature control system should be checked to prevent temperature failure, which may cause the electric furnace wire to burn out.
