electric thermal oil boiler are highly efficient thermal energy equipment in industrial production, and their stable operation is crucial for production. However, in actual operation, users often encounter some typical problems. This article will provide professional cause analysis and handling suggestions for several common faults, helping you ensure the safe and efficient operation of the system.
Q: Why does the pressure gauge keep fluctuating with large variations?
A: This happens when the system still contains air inside. Circulating it continuously for some time will naturally stabilize the pressure gauge.
Q: Why can the air not be fully expelled?
A: This could be due to two reasons: 1. There may be too many elbows on site, which require a longer time to vent. 2. The equipment and exhaust pipe might not be installed at the designated location, which is the highest point of the entire circulation system. This can also prevent complete air removal.
Q: Why does the high-temperature circulation pump often make abnormal noises during operation?
A: There are two possible reasons: 1. Some air remains in the pipeline. 2. Weld residue entered the pump during welding.
Q: Can we turn off the heating directly after work?
A: Yes, you can turn off the heating, but you should wait until the oil temperature drops below 100°C before stopping the circulation pump. Stopping both the heating and the circulation pump at the same time can cause the oil temperature to rise, leading to carbonization of the heat transfer oil, and this will affect its service life.
