In coal mine safety operations, the application of vibration motors is crucial. However, once there is a leakage in the cable connected to the vibration motor, it may pose significant safety hazards. Below, Yaan Electric Power provides you with solutions for the safe use of vibration motors in coal mines:

 

Firstly, preventive measures against coal dust ignition must be implemented:

 

1. Selection of explosion-proof equipment: Underground electrical equipment must be explosion-proof, such as explosion-proof vibration motors, explosion-proof bin wall vibrators, explosion-proof vibrators, etc. Additionally, feeders and other equipment must also be designed with explosion-proof features.

2. Prevention of electrical sparks: Attention should be paid to preventing electrical sparks at vibration motor cable joints.

3. Removal of flammable and explosive materials: Flammable and explosive materials around the vibration motor should be promptly removed to ensure a safe working environment.

 

During the conclusion of operations, special attention should be paid to the following:

 

1. Inspection of vibration motor condition: After cessation of use, the condition of the vibration motor should be rechecked to ensure there are no abnormalities.

2. Maintenance of equipment and environmental hygiene: Equipment and environmental hygiene should be maintained in accordance with the requirements of "no four" and "no five leaks" to ensure operational safety.

3. Record-keeping and handover: Equipment operation records should be filled out as required, and handover work should be properly conducted to ensure smooth communication of information.

 

Vibration motors generate exciting force through high-speed rotation of the shaft and eccentric blocks. They possess advantages such as high excitation force, low energy consumption, low noise, long lifespan, and continuous adjustment capability. They are commonly used in various silos, hoppers, chutes, where wall vibration prevents material stagnation and promotes rapid material movement. Additionally, vibration motors serve as ideal vibration sources for various vibrating machinery such as linear vibrating screens, vibrating feeders, vibrating hoppers, and vibrating conveyors.
