PTC heater is a relatively popular liquid heating equipment, which can heat the liquid in a relatively short time. If improperly handled during the heating process, it will encounter many failures and reduce the application life of the electric heater. What are the problems with electric heaters that you often encounter in life?
1. Electric heaters that have been used for a period of time may show signs of failure to heat up
(1) The heating wire in the electric heater is broken. The punishment technique is to connect the broken thread or replace it with a new one;
(2) The clear looseness leads to poor contact, so the clear connection can be reconnected.
2. If the electric heating tube is broken during the application of the electric heater
Need to replace the electric heating tube.
3. The PTC heater is powered off
(1) If the electric heating tube is powered off, just bake it in the oven;
(2) If the insulation effect is still not very good and the power supply environment will still appear, the electric heating tube should be replaced;
(3) Water in the junction box or damage to the wire insulation will also show signs of power failure. You can blow dry and wrap the damaged area with insulating tape.
Frequent failures of electric heaters:
1. Unable to heat (the heating wire in the electric heater is broken or the wire is broken at the junction box)
2. The heating tube is chipped or broken (the heating tube is cracked, the heating tube is corroded and broken, etc.)
3. Power failure (it is important that the automatic circuit breaker or power protection switch is tripped, and the electric heating tube cannot be heated), usually the failure of this environment accounts for more than 90% of the failure of the electric heater
Disciplinary skills:
1. If the heater cannot be heated, and the electric heating tube is broken, it can only be replaced if it cannot be repaired; if it is clear or the open circuit or looseness is discussed, it can be renewed.
2. If the electric heating tube is broken or broken, you can only replace the electric heating tube.
3. If it is a power failure, confirm the power failure point and consider the environment. If it is the electric heating tube itself, it can be baked in an oven; if the insulation resistance does not go up, the electric heating tube may be replaced; if the junction box enters water, use a hot air gun to dry; if the wire is broken, it can be wrapped or replaced with tape electric wire.
After the electric heater fails, it is very stressful to find out the cause in time and deal with the problem. In the future, when the electric heater is used, everyone must deal with the problem properly to prevent personal disturbance.
