Quartz electric heating tube is an electric heating element that converts electrical energy into thermal energy. It can be used alone or as an electric heating element in various electric heating devices.
Due to the special material and structure of quartz electric heating tubes, some matters need attention during installation and storage. What are these matters? Please see below!
Installation precautions for quartz electric heating tubes:
* During use, the heating tube should generally be kept basically horizontal. If possible, place the ceramic heads at both ends of the heating tube in a low-temperature area to extend the service life of the heating tube.
* The heating tube should not be rigidly fixed at both ends to avoid breakage due to improper mechanical external force.
* The ceramic bases at both ends of the heating tube and the support parts of the equipment should be as freely matched as possible, and the axial and peripheral clearance should be no less than 1-3mm; if elastic clamping is used, ensure sufficient thermal expansion space between the tube body and the rigid body.
* For heating tubes with a gold-plated reflective layer, avoid scratching the reflective layer with hard objects during installation and use.
* When installing the power lead wires of the heating tube, please sleeve them with high-temperature resistant insulating ceramic tubes or fiberglass tubes to avoid possible electric leakage hazards.
* Since the starting current of the heating tube in cold state is relatively large (short duration), pay attention to this characteristic when selecting temperature control equipment.
Storage precautions for quartz electric heating tubes
1. The storage location of quartz electric heating tubes must be kept dry with appropriate insulation resistance. If the insulation resistance of the storage environment is found to be too low during use, it can be restored by applying low voltage power before use. The heating tube should be properly fixed before use, and the wiring part should be placed outside the insulation layer, avoiding contact with corrosive, explosive media and water.
2. The heating tube should be properly positioned and fixed. The effective heating area must be completely immersed in liquid or metal solid. Dry burning is strictly prohibited. If scale or carbon deposits are found on the tube surface, clean them promptly to avoid affecting heat dissipation and shortening service life.
3. Components should be stored in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, dry them in an oven at about 200°C, or apply reduced voltage to heat until the insulation resistance is restored.
4. The wiring part should be placed outside the insulation layer, avoiding contact with corrosive, explosive media and moisture. The lead wires should be able to withstand the temperature of the wiring part and the heating load for a long time. Avoid excessive force when tightening the wiring screws.
5. The magnesium oxide powder at the outlet end of the heating tube should be protected from contaminants and moisture in the use environment to prevent electric leakage accidents.
