What are the common problems in the application of resistance finned heating element?
Since the application of finned tubes is very wide, what problems will be encountered when using resistance finned heating element, let us take a look.
1.Resistance finned heating element with fins (U-shaped, W-shaped and M-shaped stainless steel resistance finned heating element can be customized according to customer requirements for use in electric ovens, drying boxes, bakeries and other empty gas heating places) . Pay attention to the fin type The heating tube must be completely embedded in the object to be heated, and no air-fired resistance finned heating element is allowed. After using the resistance finned heating element, if there is dirt or carbon on the surface of the metal hose shell, it should be removed immediately to prevent the heat dissipation characteristics and service life of the resistance finned heating element from being damaged.
2.The storage part of the heat sink heater must be kept dry and moderate ground resistance. If the ground resistance of the natural environment of the heat sink heater is found to be too small during application, it can be used after repairing with a low -voltage power supply. The resistance finned heating element must be properly fixed before application, and a part of the wiring must be placed outside the insulation layer to prevent contact with corrosion, flammable substances and water.
3.The heating tube of the drying oven must first heat the chemical substances when the metal materials that are easy to melt and the chemical substances such as solid nitrate, paraffin, and asphalt are heated. At this time, reduce the external working voltage of the heat sink heater, and repair it to the rated current after melting. In addition, when the radiator heats up nitrates and other chemicals that are likely to cause explosions, safety measures must be taken into consideration.
4.When using the oven heating tube for gas heating, please pay attention to the uniform ordering of the radiator heating tube. The advantage of this is that a sufficient and uniform indoor space for heat dissipation of the heat pipe is ensured in the heat sink heating tube, the gas circulation is ensured as much as possible, and the heating efficiency of the heat sink heating tube is improved.
5.The gap in the heating tube of the barn is filled with magnesia sand.The magnesia sand is easily polluted by the environment because of the infiltration of residues and moisture at the end of the exit web of the resistance finned heating element group. Therefore , in actual operation, attention should be paid to the outlet web end of the finned tube group to prevent leakage safety accidents caused by this.
