Efficient Technology First |KMbalancerPro Multifunctional Mechanical Condition Analyzer Boosts Efficiency Of Vibration Condition Monitoring in The Wind Turbine Manufacturing Industry!
Misalignment is the most common failure of fans, and 60% of fan failures are related to misalignment. The misalignment fault of a fan is the degree of tilt or offset between the axis line of the two rotors of the fan and motor and the centerline of the bearings. Fan rotor misalignment can be divided into coupling misalignment and bearing misalignment. Bearing is a key component to support the normal operation of the motor, in a sense, the effect of bearing operation directly determines the service life and quality of the motor.
A customer in Guangdong has a large vibration in the fan line, the manufacturer has done a variety of measures such as bearing replacement, but the vibration has not been resolved, KM engineers with KMbalancerPro multifunctional mechanical condition analyzer in the customer's site inspection of the 2 sets of wind turbines, the test results of the existence of one bearing is not in the center of the other fan motor has a clear electrical faults.
In response to the specific problems detected, KM engineers quickly developed targeted solutions. For fans with misaligned bearings, the engineers advised the customer to carry out a detailed shaft alignment adjustment. By accurately measuring the deviation between the centerline of the two rotor shafts and the centerline of the bearings, professional tools were used to gradually correct them to ensure that the components were in the best fit. During the adjustment process, the on-site personnel also paid special attention to the preload and clearance settings of the bearings to prevent new failures caused by improper adjustment.
For another fan motor with electrical faults, KM engineers used the electrical detection function of the KMbalancerPro multifunctional mechanical condition analyzer to analyze the motor's current and voltage waveforms and harmonic content in depth, and ultimately pinpointed the existence of a local short-circuit problem in the motor's windings. Subsequently, they assisted the customer in dismantling and repairing the motor, replacing the damaged winding part, and re-conducting insulation treatment and performance testing to ensure that the motor returned to normal operation.
After this series of precise and efficient maintenance measures, the vibration problems of the two fans have been fundamentally solved, with smoother operation and significantly reduced noise. The customer highly evaluated the professional ability and service attitude of KM engineers, and indicated that they will continue to cooperate in the future to jointly maintain the efficient and stable operation of the equipment. The repair not only solved the customer's urgent problem, but also further demonstrated KM's deep strength and rich experience in the field of fan fault diagnosis and repair. In the future, KM will continue to be committed to technological innovation and service optimization to provide customers with more comprehensive and professional solutions to help enterprises achieve sustainable development.
