What are the precautions for cast aluminum electric heaters during operation?

Cast aluminum electric heaters are used very frequently in today's society. However, when using them, if you do not understand the relevant usage methods and precautions, you must not blindly carry out them, otherwise it is likely to damage the equipment and bring danger to yourself. Next, let's take a look at the precautions for electric heaters at work.

If the equipment is used in explosion-proof places, it can only be turned off after the power is turned off, and all the junction boxes with electrical parts such as heaters, liquid level controllers, humidity transmitters or flow meters can be opened, otherwise it is easy to cause explosion accidents.

When the flow is abnormal or there is no flow, do not start the heater blindly, otherwise it will cause the equipment to burn out; regularly check the reliability and sensitivity of the temperature transmitter; check the temperature transmitter and the flange to ensure that there is no leakage, and check the grounding resistance value regularly; when used in flammable and explosive media, it is necessary to strictly check the explosion-proof level, and it is recommended to negotiate with professional technical departments for future planning and construction.

The equipment must be powered on for testing after the liquid system is in normal condition; the input voltage should be consistent with the voltage designed for the equipment, and the input and output circuits should be connected accurately; the humidity of the working environment of the electric heating element should not be greater than 95%, and there should be no explosive and corrosive gases; the electric heating element needs to be stored in a dry place.

When heating liquid, the effective heating area must be fully immersed in the liquid, and care must be taken not to dry burn. When scale and carbon are found on the surface of the heating tube, it needs to be cleaned up in time, otherwise it will affect the heat dissipation and shorten the service life of the equipment; when heating nitrate, safety measures should be taken into consideration to avoid explosion accidents and make emergency plans for accidents; the wiring needs to be placed outside the insulation layer to avoid contact with corrosive and explosive substances. The lead wire needs to withstand the humidity and heating load of the wiring part for a long time. When tightening the wiring screws, avoid excessive force to cause damage to the terminal.

The above is an introduction to the precautions when using cast aluminum electric heaters. We hope that through these contents, we can enhance everyone's safety awareness in using the equipment, master the relevant precautions, enrich their own usage experience, improve the usage efficiency, and ensure the safe and effective operation of the equipment.
