Steam Turbine Maintenance Bolt Heating Rod
Main Purpose:
Widely used in plastic machinery, molds, cable machinery, alloy die-casting machines, pipelines, chemical industry, rubber, petroleum and other equipment
Precautions for using cast aluminum electric heater:
1. The working voltage shall not exceed 10% of the rated value; the relative humidity of the air shall not exceed 95%, and there shall be no explosive and corrosive gases.
2. The wiring part should be placed outside the heating layer and insulation layer, and the shell should be effectively grounded; avoid contact with corrosive, explosive media and moisture; the lead wire should be able to withstand the temperature of the wiring part and the heating load for a long time, and avoid excessive force when tightening the wiring screws.
3. The metal casting heater should be placed in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, it can be baked in an oven at about 200°C for 5-6 hours to restore normal. Or reduce the voltage and heat up until the insulation resistance is restored.
4. The metal casting heater should be fixed in position, and the effective heating area must be in close contact with the heated body. No dry burning is allowed. If dust or pollutants are found on the surface, clean them up before use to avoid affecting heat dissipation and shortening service life.
5. The magnesium oxide powder at the outlet end of the electric heating tube should avoid contamination and moisture infiltration at the use site to prevent leakage accidents.
