Language Common faults and maintenance of ptc heaters Fault 1: The power indicator light is off, the digital display does not work, and the voltmeter has no indication. Check whether the air switch is closed and whether the control loop fuse is in good condition. Fault 2: The heater temperature does not rise.
Fault 3: Three-phase imbalance, open the air ptc heater protective cover, use a multimeter to check whether the single electric heating element is open circuit, and then replace it with a special matching wrench. Care should be taken not to damage the rubber gasket when replacing. For faults that cannot be eliminated by themselves, skilled technicians should be invited to solve them. High heating temperature: The maximum working temperature of the electric ball valve heater is designed to reach 280 ℃.
The outlet temperature of the medium is uniform and the temperature control accuracy is high. The ptc heater has a wide range of applications and strong adaptability: the heater can be suitable for explosion-proof or ordinary occasions, the explosion-proof grade can reach dⅡB grade and C grade, and the pressure resistance can reach 20MPa.
The ptc heater has a long service life and high reliability: the heater is made of special electric heating materials, designed with low surface power load, and adopts multiple protections, which greatly increases the safety and service life of the ptc heater. The ptc heater can be fully automatically controlled: according to the requirements of the heater circuit design, it is convenient to realize automatic control of parameters such as outlet temperature, flow rate, pressure, etc., and can be networked with a computer.
