What should be paid attention to in the use of the bearings in the electric heater?
Safety knowledge of cold electric heater
1, do not put the warm air heater directly around the power outlet. Do not touch the heating elements inside the heater by hand, so as to prevent danger;
2, industrial air heater air outlet pipe and the temperature of the air can be sent out very high, should pay attention to prevent burns;
3, industrial air heater equipment address away from flammable, explosive and other dangerous goods and gases, to prevent danger;
4. Do not allow the use of warm air machines in any water or humid place. If water is poured into the heater, the machine may cause short circuit or leakage;
5, the emergence of emergencies, can be directly pressed by the emergency brake off, after the security has been guaranteed, you can reset, restore work;
6, industrial air heater equipment address ventilation excellent, do not use in the sealed box;
7, before using the warm air machine, must check the voltage and current can meet the requirements of the machine, you must use a grounding socket, wire must comply with the request.
Then, what should be paid attention to in the use of the bearings in the electric heater?
Production loss is mainly affecting the core data and winding data of two parts: the core data is in the silicon steel sheet, steel sheet of silicon can decrease the conductive function of its own, and then add the cut resistivity of eddy current loss so the quality and quality of silicon steel sheet heater has great relationship. We usually use the flux density to indicate the quality of silicon steel sheet. The winding wire making it the common data, to show that the loss by the copper loss bearing heater on proper and small transformer is greater than the loss of copper copper loss so the data and information technology for winding is very high the best selection of high strength polyester enameled wire, its resistance value is relatively small, good conductive function, the insulating varnish layer has to meet the heat function, so the heater function with high strength polyester enameled wire is more superior.
Some electric heaters must be customized according to user requirements
1. operating temperature
2. detailed structural dimensions
3. heating power
1) the work voltage shall not exceed 10% of the rated value;
2) the wiring part is outside the heating layer and insulation layer, and the case should be grounded effectively;
3) the cast aluminum heater should be placed in the dry place. If the insulation resistance is lower than 1M ohms for a long time, it can bake in the oven for about 5-6 hours at about 200 degrees Celsius and then return to normal
