Electric heating tube manufacturers introduce common faults and solutions for electric heating tubes, and answer some of the problems that may arise during use after purchasing electric heating tubes. Our company has compiled the following common electric heating tube faults and solutions for your reference.
Fault-the resistance wire is blown out
Reasons: the heating tube burns and causes a short circuit; the lead or lead wire of the heating tube falls off and causes a short circuit; the diameter of the resistance wire is too small, and the capacity is insufficient; the electric heating socket accumulates dirt or carbonization causes a short circuit; the power cord plug and the electric heating socket short circuit;
Solution: replace the heating tube; re-welding; replace the suitable resistance wire electric heating tube, under normal circumstances, the iron-chromium-aluminum resistance wire can be used. Remove dirt, repair or replace parts; E. Repair or replace the power plug or electric socket;
failure-no heat
Reason: For the adjustable temperature control heating tube, the contact of the temperature controller is poorly contacted or melted off. Abnormal power supply or power failure; the resistance wire has been fused; the power cord plug is in poor contact with the electric heating socket, or the power cord wire is open; the electric heating tube has been burned; the electric heating tube lead or lead is off;
Solution: The heating tube is not easy to repair, it is recommended to replace it; use after the power supply is normal; the heating tube is scrapped, re-produce and install the same type of resistance wire; check the circuit for repair or replacement; replace and install the same specification electric heating tube; re-weld the lead or lead ;
Fault——Leakage
Reasons: the circuit wire falls off and touches the cup body; the heating tube is burned out and the cup body is short-circuited; the ground wire is not properly connected; the heating socket or power plug is too dirty; the insulation of the heating tube is damaged; improper cleaning, moisture leaks into the cup;
Solution: check the disconnected wire and re-weld it firmly; the electric heating tube is damaged and replace the electric heating tube of the same specification; connect the ground wire as required and check whether it is correct; clean and dry properly; check and repair if such an event still occurs, it is recommended to replace it; correct Clean and dry;
Introduction to electric heating tube manufacturers, here is the content of common faults and solutions for electric heating tubes. When repairing electric heating tubes, you need to understand the wiring methods of electric heating tubes. By the way, I will explain the wiring methods of two electric heating tubes.
1. Delta connection: the first end of each element of the electric heating tube is connected to the end of another element, and the three contacts are respectively connected to three phase wires; characteristics: the rated voltage of the three electric heating tube elements is 380 volts; such as three The different resistance values of the components do not affect the feasibility of this connection. The power and current of the delta connection are three times larger than that of the star connection.
2. Star connection: the heating elements of three electric heating tubes, the head of each element is connected together (this point is called the neutral point), and the three tail ends are respectively connected to the three phase wires. Features: When the rated voltage of the three components is 220V; if the resistance values of the three components are different, the neutral point should be connected to the neutral line.
