Analysis of electric heater fault causes and related remedial measures
Electric heater is a device that consumes electrical energy to convert it into heat energy for heating the material to be heated. During operation of the explosion-proof electric heater, the low-temperature fluid medium enters its inlet through the pipeline under pressure, flows along the specific heat exchange channel inside the electric heating container, following the path designed based on fluid thermodynamics principles, carrying away the high-temperature heat energy generated by the electric heating elements during operation, thereby raising the temperature of the heated medium.
Today, the editor mainly introduces the fault causes and remedial methods that may occur during the operation of electric heaters, so that everyone can better use electric heaters correctly and provide some help!
1. If leakage is found at the inlet and outlet flanges of the electric heater, it is likely that the sealing gasket has been damaged. At this time, replacing the sealing gasket can solve the leakage problem.
2. If the electric heater system cannot start normally, it may be caused by two reasons:
(1) It may be caused by the emergency stop button of the control cabinet not being reset. At this time, the emergency stop button needs to be reset to solve the problem.
(2) It may be caused by incorrect interlocking of the interlock contacts. At this time, it is necessary to find the incorrectly interlocked contacts and restore them to normal.
3. If the ammeter reading shows phase loss or imbalance, there may be three reasons:
(1) The pointer of the ammeter is not flexible. At this time, the ammeter can be repaired or directly replaced to fix it.
(2) The circuit breaker is missing a phase when closed. At this time, the circuit breaker should be replaced to fix it.
(3) The thyristor module or fuse is damaged. At this time, the thyristor module and fuse can be directly replaced to fix it.
