INTRODUCTION

Test Motors, through its online predictive maintenance tool, SMS, allow you to easily monitor all the motors of your production process at a very competitive price and predict your failures. The Smart Motor Sensor is a smart wireless device that is capable of detecting machine breakdowns automatically, using a Wi-Fi network, through a learning process and artificial intelligence, which plays a key role in industry 4.0.  In this case we will talk about a centrifugal pump driven by a three-phase asynchronous motor, with a power of 18.5kW.

FAILURE DETECTION

Thanks to the continuous monitoring of the vibrations made by the sensor, it allows to detect in real time any alteration of the machine's operation. The system generated a warning through the mobile application, and by email where an alteration is detected that leads to a failure of the bearings.  

GRAf

FAULT SIGNS:
  • Trend change: From having stable values to a high trend of vibrations that indicates that the behavior of the machine has changed.
  • Peaks of the graph: The peaks that are observed in the machine indicate the presence of impacts of some component, such as the bearings.

CORRECTIVE ACTION

Once the machine is opened, the turbine is inspected and the bearings are replaced. When the replacement is made, the system detects if it returns to the usual vibration levels of the machine, indicating that the process of replacing the bearings has been carried out correctly and the machine can continue to operate until further notice.
