Shandong Meian Mining Equipment Co., Ltd. supplies coal mine motor main bearing temperature vibration monitoring devices, water pump gas pump vibration temperature online monitoring, online monitoring of operating status and intelligent fault diagnosis for large coal mine electromechanical equipment, and main bearing temperature vibration monitoring devices for coal mine belt conveyors, air compressors, hoists, fans, and motors.

On July 1, 2020, the "Basic Requirements and Scoring Methods for Coal Mine Safety Production Standardization Management System" was announced and implemented, which pointed out: Electromechanical equipment in coal mines such as hoists, wire rope traction, drum belt conveyors, belt conveyors, air compressors, pressure fans, and water pumps are required to add temperature and vibration monitoring for motors and main bearings.

Device Functions

1、Online monitoring of motor main bearing temperature and vibration for equipment such as hoists, water pumps, belt conveyors, and air compressors

2、Online monitoring of drum main bearing temperature and vibration for equipment such as hoists, water pumps, belt conveyors, and air compressors

3、Coal mine electromechanical equipment motor main bearing temperature and vibration monitoring

4、Audible and visual alerts for motor main bearing temperature and vibration exceeding limits

5、Audible and visual alerts for drum main bearing temperature and vibration exceeding limits

6、Visualized real-time curve viewing of mine motor bearing temperature and vibration parameters

7、Traceable alarm records for mine motor bearing temperature and vibration parameters

8、Remote (Ethernet or wireless network) online monitoring of drum and motor main bearing temperature and vibration parameters

9、Mine intrinsically safe temperature sensors and mine intrinsically safe vibration sensors use MEMS chips, developed and produced with embedded technology, temperature sensing technology, and vibration sensing technology for high performance, low power consumption, and anti-interference sensors. The products are widely used in the coal mining industry for online measurement of temperature and vibration in rotating equipment such as motors, reducers, fans, hoists, air compressors, belt conveyors, and water pumps.

10、The housing is made entirely of stainless steel or aluminum alloy. Threaded installation can be used where conditions permit, with standard threads on the metal housing for quick connection to the installation site. Magnetic installation is also available, eliminating the need for drilling on-site and making installation more convenient.

11、Spectrum-type products can simultaneously provide time-domain characteristic values for velocity and acceleration (RMS, peak, kurtosis coefficient), time-domain characteristic values for displacement (peak-to-peak), spectrum analysis data, and fault diagnosis results.

12、Multiple signal output options available: RS485 type, spectrum type, analog type, LoRa type.

13、Can be upgraded to a high-temperature resistant version as needed for on-site monitoring, with the transmitter contact temperature range up to -40-150°C.

14、Wired data collectors are responsible for signal acquisition, signal processing, signal analysis, and data transmission of fixed equipment in underground coal mines. They perform real-time signal analysis and upload parameters such as vibration amplitude, waveform, spectrum, envelope waveform, and envelope spectrum that reflect the vibration characteristics and status of the equipment and components to the monitoring center server.

15、Mine intrinsically safe vibration sensors are triaxial sensors: To comprehensively understand the vibration situation of the motor, XYZ triaxial sensors are used to simultaneously measure the front-back, left-right, and up-down directions of motor vibration. This provides more accurate and comprehensive vibration data, helping to identify the source and type of vibration, thereby predicting potential motor faults.

16、Equipped with frequency domain analysis function: By performing frequency domain analysis on vibration signals, such as Fast Fourier Transform (FFT), the vibration signal can be converted into a spectrum diagram, displaying vibration components at different frequencies. This helps determine whether there are specific frequency components related to motor faults, such as resonance or early wear signals, allowing for early maintenance and repair measures.
