Working Principle

When the mine centrifugal fan works, the motor drives the impeller to rotate through the transmission device, and the air between the blade flow passages rotates with the rotation of the blades, thereby obtaining centrifugal force. The impeller is thrown into the casing via the end of the leaf. After entering the cabinet, the speed will gradually decrease and the pressure will increase accordingly. However, the pressure at the inlet of the blade will decrease accordingly. In such repeated work, after centrifugal force is generated, there is pressure to make the wind flow continuously. For mining axial fan, when it works, it mainly depends on the rotation of the moving wheel, and the airflow flows out along the cylindrical surface with equal radius.

Structure

The mine fan is composed of an air collector, a casing, a motor, an impeller, a diffuser cylinder, an air cylinder joint and other parts. The fan shell and structural parts are welded with steel plates. The inner cylinder is welded with an orifice plate. The lining muffler material: the motor is sealed in the inner passage and isolated from the exhaust air in the air passage. The motor is a two-pole three-phase asynchronous motor for YBF series flameproof fans. The fan impeller is made of special materials, anti-static, non-friction spark. The air flow conveyed by the motor cooling wind wheel is cooled, and the motor is in communication with the fresh air flow.

Precautions

In order to ensure the long-term safe operation of mine fans, attention must be paid to correct use and regular maintenance. The use of extraction fans for mixed ventilation in tunneling roadways shall comply with the relevant provisions of the "Coal Mine Safety Regulations. Safety windshield should be set in front of the ventilator. Open the safety windshield before starting the ventilator. After normal operation, close the safety windshield gradually. Before starting the ventilator, check the gas content within 10 m near the ventilator and switch. When the gas concentration does not exceed 0.5%, the ventilator can be started. If the gas exceeds the limit, corresponding measures shall be taken. The ventilator stops running due to failure during operation. Before restarting, the gas concentration in the wind turbine shall be detected. If the gas concentration exceeds the standard, it shall be handled according to the provisions of coal mine safety regulations.
