Online Monitoring Device for Temperature and Vibration of Coal Mine Motor Bearings

Shandong Meian Mining Equipment Co., Ltd. supplies online monitoring of coal mine motor bearing temperature and vibration, online monitoring of coal mine electromechanical equipment temperature and vibration, online monitoring of coal mine motor bearing temperature and vibration, and online monitoring and intelligent fault diagnosis of the operating status of large coal mine electromechanical equipment.

The "Basic Requirements and Scoring Methods for the Coal Mine Safety Production Standardization Management System," implemented on July 1, 2020, states that coal mine electromechanical equipment such as hoists, wire rope traction, drum belt conveyors, belt machines, air compressors, pressure fans, and water pumps require the addition of temperature and vibration monitoring for motors and main bearings.

Coal mine motor bearing temperature and vibration monitoring systems are widely used in coal mine main fans, pressure fans, belt machines, drum belt conveyors, drainage pumps and motors, hoists, etc., helping to grasp the temperature and vibration data of motors during equipment operation.

The motor bearing temperature and vibration monitoring system features multiple communication interfaces such as RS232, RS485, and Ethernet, supporting various communication protocols including MODBUS-RTU, MODBUS-TCP, and PROFINET. The system integrates 485 communication technology, Ethernet communication technology, human-machine interface technology, and fault diagnosis technology to monitor the vibration, temperature, and other statuses of equipment motor bearings in real time, promptly identifying electromechanical equipment faults to ensure the normal operation of mine production.

Motor health analysis: Utilizes AI intelligent algorithms to identify system inefficiencies, uncover energy-saving potential, perform timely maintenance on rotating equipment, avoid equipment failures or sub-health conditions, and improve the output and quality of service products. Without replacing equipment, it reduces emissions and environmental impact while enhancing energy efficiency.
