Fault alarm of damper servo motor of thermal oil furnace
3. Fault alarm of damper servo motor of thermal oil furnace
The damper servo motor of heat-conducting oil furnace is also a part prone to failure. We summarized the common failure reasons and formulated the treatment
Methods:
Mechanical clamping of burner damper blade, loosing of servo motor and damper fixing screw are common mechanical faults
Strengthen the inspection, if there is vibration abnormal sound in time to solve.
Due to the large vibration during the operation of the thermal oil furnace, the bus connection between WFM200 and the servo motor may be loose. At this time, the furnace needs to be stopped
The servo motor is manually moved through ABE to troubleshoot faults.
Suggestion: in order to further improve the efficiency and ensure the stable and reliable operation of the thermal oil furnace, the following improvements can be made
Door opening size to control.When the air volume demand is small, the valve opening becomes smaller, but the power of the fan remains unchanged, that is, the throttle effect of the damper causes the consumption
Power losses.Can increase the frequency converter, through the frequency converter output control fan speed, so as to achieve the effect of controlling air volume.This not only eliminates it
Throttling loss, saving power, and making control more stable
