Mold temperature control machine cartridge heater
The Mold temperature control machine cartridge heater has the following attention problems:
1. The temperature relative humidity of the mold temperature machine is not more than 95%, and there is no explosive or corrosive gas. The working voltage should not be greater than 1.1 times the rated value, and the outer casing should be effectively grounded. Insulation resistance ≥1MΩ Degree: 2KV/1min.
2. The Mold temperature control machine components should be stored in a dry place. If the insulation resistance is less than 1MΩ for a long time, it can be dried in an oven of about 200 °C, or the voltage can be heated and heated until the insulation resistance is restored.
3. When the Mold temperature control machineheats the air, the components should be evenly arranged, so that the components have good heat dissipation conditions, so that the flowing air can be fully heated. When heating fusible metal or solid nitrate, alkali, bitumen, paraffin, etc., the voltage should be reduced first, and the medium can be raised to the rated voltage after the medium is melted.
4. Safety measures should be taken when heating nitrate to prevent explosion accidents.
5. 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 part for a long time, and avoid excessive force when tightening the terminal screws.
6. The Mold temperature control machine cartridge heater should be fixed and fixed. The effective heating zone must be completely immersed in liquid or metal solid. It is strictly forbidden to burn. When it is found that there is scale or carbon on the surface of the pipe body, it should be cleaned and reused in time to avoid heat dissipation and shorten the service life.
7. Magnesium oxide powder at the outlet end of the mold temperature electromechanical heat pipe avoids the infiltration of pollutants and moisture during use to prevent leakage accidents.
