Immersion water heater with thermostat use matters needing attention
components are allowed to work under the following conditions:
A. air relative humidity is not greater than 95%, no explosive and corrosive gases. (excluding explosion-proof heater)
B. The working voltage ofshould not exceed 1.1 times the rated value, and the enclosure should be effectively grounded.
C. insulation resistance is greater than 1M ohm dielectric strength: 2KV/1min.
Electric heat pipe should be fixed and positioned. The effective heating zone must be immersed in liquid or metal solids. No air burning is allowed. When dirt or carbon deposit is found on the surface of the tube, it should be cleaned up and reused in time so as to avoid heat dissipation and shorten the service life.
When heating fusible metals or solid salts of nitrate, alkali, leaching, paraffin, etc., the applied voltage should be lowered first, and after the medium is melted, it can be raised to the rated voltage.
When heating air, the elements should be arranged evenly and cross-wise, so that the elements have good heat dissipation conditions, so that the air flowing through can be fully heated.
heating nitrate should consider safety measures to prevent explosion accidents.
The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media and moisture; the wiring should be able to withstand the temperature and heating load of the wiring part for a long time; the wiring screw should be tightened to avoid overexertion.
The components should be stored in a dry place. If the insulation resistance is lower than 1M for a long time, the components can be dried in the oven at about 200 degrees Celsius or heated by lowering the voltage until the insulation resistance is restored.
