Safety Protection Device for Electric Heating Boiler

During the operation of electric heating boiler, it is necessary to deal with the complex situations such as temperature and pressure changes. The safety protection device is like a reliable "guardian", which can effectively reduce the potential risks and ensure the stable operation of the equipment.

The over-temperature protection device is one of the important protection lines. When the medium temperature in the boiler exceeds the set threshold, the device responds quickly and stops the temperature from rising by cutting off the power supply of the electric heating element or starting the cooling system. It is usually composed of temperature sensor and control module, the former monitors temperature in real time, and the latter triggers protection action timely according to data.

Pressure protection is especially critical for steam boilers. The pressure sensor continuously senses the internal pressure of the boiler. Once the pressure is too high, the safety valve will automatically open to quickly release the steam and control the pressure within the safe range. At the same time, the pressure switch will link the control system to stop heating or start the pressure relief process.

The water shortage protection device can avoid the danger of dry burning. When the boiler water level is lower than the limit value, the device will immediately cut off the power supply to prevent the heating elements from working without water and effectively avoid equipment damage or even safety accidents. In addition, the leakage protection device is also indispensable. It can capture the abnormal current in the circuit. Once the leakage phenomenon is found, cut off the power supply quickly to protect the safety of the operator.

These safety protection devices perform their own duties and cooperate with each other to jointly build the safety protection network of the electric heating boiler, so as to build a solid barrier for the stable operation of equipment and personnel safety.
