Mining Explosion-proof and Intrinsically Safe Pump Motor Bearing Temperature Monitoring Device

The explosion-proof motor bearing temperature and vibration monitoring device produced by Zhengzhou Guangzhong Technology Development Co., Ltd. meets the requirements for use in coal mines and can be applied to water pump motors, monkey car motors, hoist motors, belt conveyor motors, and other applications requiring explosion-proof motors.

I. Inspection Basis for Explosion-Proof Motor Bearing Temperature and Vibration Monitoring Device:

1. 12173-2008 "General Purpose Electrical Equipment for Mines"

2. MT 209-90 "General Technical Requirements for Electrical and Electronic Products for Coal Mine Communication, Detection, and Control"

II. Electrical Performance of Explosion-Proof Motor Bearing Temperature and Vibration Monitoring Device:

1. Test Conditions: Power supply voltage AC220V.

2. Protection Performance: Bearing temperature warning value: (110±10)°C, vibration warning value: (20±5) mm/s, distance between sensor and host is 100m.

3. Function: The host display screen shows real-time temperature and vibration data of the motor's front and rear bearings. When any of the temperature or vibration data for the front or rear bearings of the pump motor reaches the warning value, the device emits an audible and visual alarm signal.
