What should I pay attention to when using the electric heating pipe terminal?
1. Input power transformer, the working standard voltage should not exceed 10% of the rated current marked on various electric heating pipes, if the available is lower than the rated current, the calorific value caused by the electric heating tube will also be reduced.
2. At the terminal end of the electric heating pipe, 2 screw caps should be twisted relative to each other when wiring, and the force should not be too strong to prevent the screw from loosening and causing the electric heating pipe to be damaged.
3. Part of the heating of the electric heating tube should all penetrate into the heating chemicals to avoid the slow release of the calorific value and exceed the allowable heating temperature to damage the electric heating tube. In addition, part of the wiring should be exposed outside the heater's insulation plate or heater, so that this cannot overheat and cause damage.
4. The electric heating pipe terminal should be kept clean and dry, in turn will reduce the volume resistivity energy and short circuit fault common fault through, if applied to chemical corrosion, flammability, flammable and explosive materials and other liquid or gas geographical environment, should be part of the electric heating pipe wiring with cable sheath closed machinery and equipment to strictly take safety precautions to avoid safety production accidents.
5. When heating some viscose and other compounds, such as sodium nitrate, methacrylate, paraffin, etc., the power supply voltage should be reduced at the beginning of heating to reduce the heat of the electric heating tube, and when all melted into liquid, it will rise to the rated current for heating.
6. The selection of electric heating tubes should pay special attention to heating chemicals. No deposition of electric heating shell raw materials is processed.
7. The electric heating tube is used for a long time, if the surface accumulates slightly thicker pipe scale, oil stains, it should be removed on time, otherwise the thermal conductivity characteristics of the electric heating tube will be reduced and the heat load on the surface of the tube will exceed the rated current allowable and be damaged.
8. Stainless steel plate electric heating tube should be stored in a dry warehouse, if the surface is wet due to long-term placement, the application of megohmmeter to accurately measure the resistance of the grounding wire. If it is less than 1 megohm/500 volts, the electric heating tube should be put into a 200-degree oven for blow-drying.
9. The special electric heating pipe should read the relevant instructions in detail before installation and application to prevent it from being damaged.
