What are the electric heating pipe short-circuit failure and solutions?

Customers who use use heating tubes often run into the problem of short-circuit electric heating tubes, today Yancheng Hongchuang will learn with you. We need to know the common heating tube can be divided into: single-head heating tube, U-type heating tube, flange heating tube, finned heating tube and so on. The first situation: electric heating tube burned resistance wire reasons: A, electric heating tube burned caused by a short circuit; B, electric heating tube of the lead sheet or lead off caused by a short circuit; C, the diameter of the resistance wire is too small, the capacity is insufficient; D, the electric heating socket build-up of dirt or carbonization caused by a short circuit E, power cord plug and electric heating socket short circuit; solution: A, replace the heating tube; B, rewelding connection; C, replacement of the appropriate resistance wire electric heating tube, the Yancheng Hongchuang technical department research, under normal circumstances, the resistance wire of iron chrome aluminum can be used. D, remove dirt, repair or replace parts E, repair or replace the power plug or electric socket; the second situation: the electric heating tube does not heat the reason: A, for adjustable temperature-controlled heating tube, thermostat contacts poor contact or burnt fusion disengagement. B, power supply is not normal or blackout; C, the resistance wire has blown; D, power cord plug and electric socket contact is poor, or power cord wire break; E, the electric heating tube has burned; F, the electric heating tube lead or lead off; solution: A, the heating tube is not good for maintenance, it is recommended to replace; B, power supply is normal and then use; C, the heating tube is scrapped, and re-production of installing the same type of resistance wire; D, checking the line to repair or Replacement; E, replacement and installation of the same specifications of the electric heating tube; F, re-welding lead or lead; the third situation: electric heating tube leakage Reason: A, the circuit wire falling off and the cup touching; B, burned out and the cup short circuit; C, not connected to a good ground; D, electric socket or power plug too much dirt; E, electric heating tube insulation damage; F, cleaning is not appropriate, moisture exposure to the cup; Solution: A, check the fall-off lead, re-welding; B, electric heating socket or power plug is too dirty; E, electric heating tube insulation damage; F, cleaning is not appropriate, moisture exposure to the cup; solution: A, check the lead, rewelding; B, electric heating Re-solder; B, the electric heating tube has been damaged to replace the same specifications of the electric heating tube; C, according to the requirements of the ground wire and check whether it is correct; D, properly cleaned and dry processing; E, check and repair if there is still such an event is recommended to be replaced; F, correctly cleaned and dry processing; the above summary, for reference only. More heating tube problems, we are willing to participate with customers
