Through fan health monitoring, can improve reliability, security and the efficiency of fan equipment, reduce down time and cost of maintenance. The following are some key aspects of fan health monitoring: vibration monitoring: by installing equipment such as a vibration sensor, the vibration condition of the fan is monitored in real time. Abnormal vibration can indicate possible faults or unbalance problems, and timely measures are taken for maintenance and adjustment. And (3) temperature monitoring: the temperature of the fan is monitored in real time through equipment such as a temperature sensor. Abnormal temperature changes may be caused by faults, friction or overload, and timely monitoring can prevent equipment damage and safety accidents. Pressure monitoring: the inlet and outlet pressure of the fan is monitored, so that the performance and the flow of the fan can be evaluated. Abnormal pressure changes may be caused by blockages, leaks, or other problems, and timely monitoring may indicate a problem and take corresponding maintenance action. Current monitoring: the current change of the fan is monitored in real time through devices such as a current sensor. Abnormal current fluctuations may indicate motor faults, power supply problems, or circuit faults, and timely monitoring may prevent equipment damage and electrical accidents. Data analysis and alarm: by analyzing and processing the real-time monitoring data, potential faults and problems are identified, and an alarm is timely given. This can help the service personnel respond quickly and take appropriate repair and maintenance measures to ensure reliable operation of the fan apparatus.
