The special heating tube should read the instructions carefully before installation and application to prevent damage. The hot part of the single-ended heating tube penetrates into the heating material, and the heating value of the heating tube must not gradually exceed the allowable heating temperature to avoid damage. In addition, part of the wires should be exposed to the insulating layer or outside of the electric heater to avoid excessive temperature and hazards.
After inputting the switching power supply, it shall not exceed 10% of the rated current on each heating tube. If the application is less than the rated current, the heat generated by a single heating tube will also be reduced. When wiring, use two nuts to tighten the terminals of the heating tube oppositely to avoid forcing the screws to loosen and damage the heating tube. Clean the terminals of the single-head heating tube. Dry impatience, but due to short-circuit failure, the dielectric strength and energy are reduced.
Using the natural environment of liquid or vapor such as chemical corrosion, flammability, flammable explosion, etc., part of the sealing equipment of the heating pipeline can be safely protected to prevent safety accidents. When heating certain chemical substances (such as sodium nitrate, paraffin, etc.), the power supply voltage should be reduced during heating to reduce the heating value of the heating tube, and then increase to the rated heating current.
When using a single-head heating tube, pay attention to the heating material. There is no sedimentation of the raw materials of the heating tube and shell. Single-head electric heating tubes should be stored in the dry warehouse. Since the surface is wet for a long time, a megohmmeter should be used to measure the grounding resistance in the application. If it is less than 1 megohm/500 volts, put the heating tube into a 200 degree drying oven for air drying. The single-head heating tube has a long application time, and thick tube scale accumulates on the surface. When the oil is dirty, it must be removed at any time. Otherwise, the thermal conductivity of the heating tube will be reduced, and the heat consumption on the surface of the tube will exceed the rated value
