Analysis of Electric Heater Fault Causes and Related Remedial Measures
An electric heater is a device that converts electrical energy into thermal energy to heat the material to be heated. Explosion-proof electric heater In operation, the low-temperature fluid medium enters its input port through a pipeline under pressure, flows along a specific heat exchange channel inside the electric heating container, and follows a path designed based on fluid thermodynamics principles, carrying away the high-temperature thermal 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. In this case, 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 due to the emergency stop button on the control cabinet not being reset. In this case, the emergency stop button needs to be reset to resolve the issue.
(2) It may be caused by an incorrect interlock of the interlock contacts. In this case, the incorrectly interlocked contacts need to be identified and restored to normal.
3. If the ammeter reading of the equipment shows a phase loss or imbalance, there may be three reasons:
(1) The pointer of the ammeter is not flexible. In this case, the ammeter can be repaired or directly replaced to fix it.
(2) The circuit breaker of the equipment has a phase loss when closed. In this case, the circuit breaker should be replaced to fix it.
(3) The thyristor module or fuse is damaged. In this case, the thyristor module and fuse can be directly replaced to fix it.
