Key Points of Electric Heater Design:
According to the corrosion of potion to confirm the material of electric heater.
Operation temperature of the liquid medicine: The design durability of electric heater is directly related to the working temperature of potion. According to the working temperature, to design the surface power load of electric heater.
Functions and Types of Temperature Overheating Protectors for Electric Heaters:
Temperature fuse: the temperature fuse is installed in the casing next to the heater; When the liquid level is lowered and the temperature exceeds the safe value of the fuse, the fuse will burn off and act as a protective tank and electric heater. The fuse should be replaced after burning. The selection parameters of temperature fuse are 250V5A105 °C or 95 °C.
Temperature switch: the temperature switch is installed in the casing beside the heater, when the liquid is lowered, the temperature switch temperature is higher than the temperature control point, the temperature switch is turned on, the power supply is turned off, and when the temperature is lowered, the temperature switch can re-turn on the power supply. Parameters of the temperature switch:250 V5A105 ° C or 95 ° C.
The returning temperature of the switch is 15 °C lower than the overtemperature point.
Due to the limitation of the power-on current, the temperature fuse and the temperature switch cannot be directly connected to the load of the power supply and the electric heater.
