- Operate the blower in a clean place and use an air filter.
- Replace the bearing on time.
5. Motor Overload
Problem: Too much pressure is being applied on the motor.
Reason:
- Too much pressure or blockage in the system.
- Problem in power supply.
- Wrong setting or design of the motor.
- The motor gets heated due to lack of air around it.
Simple solution:
- Keep the system pressure according to the capacity of the blower and motor.
- Keep the power supply correct and check the voltage.
- Check the rating and setting of the motor.
- Make arrangements for air circulation around the motor.
Prevention is the cure (Preventive Maintenance)
To reduce problems in the blower, it is important that you keep taking care of it from time to time.
Keep checking: Check all the parts of the blower such as moving parts, bearings, gears and seals regularly.
