In the process of heating water by industrial electric heating tubes, the damage of electric heating tubes often occurs. How to understand the principles to prevent such things from happening. In the process of electric heating tube damage, part of the problem is the material of the electric heating tube, and part of the damage is caused by human operation. The material problem of the electric heating tube can be solved by purchasing good quality products, but for the part of human operation, we need to strengthen the analysis of the cause of the damage. According to the consultation and statistics, the materials are organized as follows:
When boiling water, you need to put the electric heating tube inside a non-conductive thing to boil the water, and it must be higher than the heating surface, and do not get the water on the joint to prevent leakage. Keep the connector as clean as possible. Don’t dry out due to lack of water. It is easy to burn out and puncture. If the power is high, it can also cause the tube to burst. Ground connection is required, and safety is considered. If it trips, the water in the heating tube should be dried, and then measured with a high-voltage instrument, or measured with a megohmmeter. The simplest method is to measure the leakage with a multimeter (DC gear), generally Leakage should not exceed 50V. If it reaches 110V, it must not be used (which will cause electric shock), and replace it with a new electric heating tube. There is also what voltage you use is industrial 380V or household 220V. It depends on whether you are using it for household or industrial use. There are grounding wires for industrial use, and a temperature control cabinet can be equipped if possible. At home, you can turn off the switch or open the knife when the water is boiled (if possible, you can equip a thermocouple or connect a fuse to the thermostat). Of course, the home kettle is simple. When the water is boiled, turn off the switch or open the knife. Some kettles will power off after they boil, and the water must be higher than the heating surface.
