How to use and maintain single head tube

How to use and maintain single head tube

1. The single-head tube has been used for a long time. If thick tube dirt and grease accumulate on the surface, it should be removed regularly, otherwise it will reduce the heat transfer performance of the single-head tube and cause the heat load of the tube surface to exceed the rated allowable damage. 2. The heating part of the single-head tube should be completely immersed in the heating medium to prevent the single-head tube from being damaged by undesirable heat dissipation and exceeding the allowable heating temperature. In addition, the lead-out part of the wiring should be exposed to the heat insulation layer of the heater or outside the heater, so that this part should not be overheated and damaged. 3. The single-head tube terminal should be kept clean and dry, otherwise it will reduce the insulation performance and be short-circuited. If it is used in a chemically corrosive, flammable, explosive and other liquid or gas environment, the single-head tube should be connected Strictly protect with insulating and sealing devices to prevent accidents. 4. When heating certain viscose and other substances, such as sodium nitrate, stearic acid, paraffin, etc., the power supply voltage should be lowered at the beginning of heating to reduce the heat generation of the single-head tube, and when it is completely melted into liquid, it will rise to Rated voltage for heating. 5. Input power, the voltage should not exceed 10% of the rated voltage marked on the various single-head tubes. If it is suitable for lower than the rated voltage, the heat generated by the single-head tube will also decrease. 6. The special single-head tube should be carefully read the relevant instructions before installation and use to avoid damage. 7. For the terminal of the single-head tube, use 2 nuts to tighten it relative to each other when wiring. Do not use too much force to avoid the loosening of the lead screw and damage the single-head tube. 8. Special attention should be paid to heating medium when selecting single-head tube. It has no corrosive effect on the single-head tube shell material. 9. The single-head tube should be stored in a dry warehouse. If the surface is damp due to long-term storage, use a megohmmeter to measure the insulation resistance. If it is less than 1 megohm/500 volts, the single-head tube should be placed in a 200 degree drying oven for drying.
