The application field of electric heating tubes has accounted for more than 60% of the market. Due to the large market share, the failure of electric heating tubes has also increased. Although electric heating tubes have been used for a long time, many customers have not yet understood the faults and treatment methods of electric heating tubes. Today, the editor also spent a lot of effort to sort out a few common faults and solutions for industrial electric heating tubes. Let’s take a look.
Fault ①The resistance wire burns
Reasons: short circuit caused by the burning of the heating tube; short circuit caused by the falling off of the guide plate or wire of the heating tube; short circuit caused by the small diameter of the resistance wire and insufficient capacity; short circuit caused by the dirt or carbonization of the electric heating socket; short circuit between the power cord plug and the electric heating socket;
Solution: replace the heating tube; re-welding; replace the suitable resistance wire electric heating tube, under normal circumstances, iron, chromium, aluminum resistance wire can be used. Remove dirt, repair or replace parts; repair or replace power plugs or electric heating sockets.
Fault ②No heating up
Reason: For the adjustable temperature control heating tube, the contact of the temperature controller is not good or melted, the power supply is abnormal or out of power, the resistance wire is melted, the power cord plug and the electric heating socket have poor contact, the wire is broken, the electric heating tube is burned, and the heat pipe guide plate Or the lead falls off.
Solution: The heating tube is not easy to repair, it is recommended to replace it; the power supply is used normally; the heating tube is scrapped, the same type of resistance wire is reinstalled; the inspection line is repaired or replaced; the electric heating tube of the same specification is replaced and installed; the guide plate or lead wire is re-welded.
Fault ③Leakage phenomenon occurs
Reasons: the wire falls off and the cup body collides; the electric heating tube burns and the cup body is short-circuited; it is not connected to the ground wire; the electric heating socket or power plug is too dirty; the insulation of the electric heating tube is damaged; improper cleaning, and the water is exposed to the cup.
Solution: check the disconnection and re-welding; the electric heating tube is damaged, replace it with the same specification electric heating tube; connect the ground wire as required and check whether it is correct; clean and dry correctly; check whether it is still recommended for replacement; clean and dry properly.
The failure phenomenon is that all the workmanship products on the market will appear, but the most important thing is that we know what the failure is and how to deal with it, in order to ensure the safety of property and life, especially the electric heating tube we use at home to boil water. Do not use if there is no heating, leakage, or exposed inner plastic wires. When I used the electric heating tube purchased on the market, it burned due to the poor quality of the wire. Therefore, if there is a failure when using the electric heating tube, please remove the fault and confirm the safety before using it. Our company has been manufacturing electric heating tubes for more than ten years, focusing on electric heating tubes, heating tubes, industrial electric heating tubes, stainless steel electric heating tubes, etc. If you have the above requirements, you can contact our company.
