Precautions for Installation Use of Mining Ventilation Fan
The casing diameter of the mines ventilation fan is larger than the impeller diameter of the fan to reduce the resistance of the fan casing itself, improve the ventilation efficiency; 2x 18.5kW mining axial fan must be used to use a strong wind tube to prevent the wind pressure from being too high.
1. Two motors in the LVR series, when wiring, should be tried in a single trial; the LVRC series fan is installed. The direction of rotation of the motor is consistent with the direction arrow.
2, when the LVR series is started with the whirlwind, the first-stage fan should be started, and the second stage fan is started after normal operation.
3. For high-power local ventilators, we must add lubricants to the front and rear bearings of the motor, extend the service life; dust and debris on the orifice plate, and the stotted sound material is cleaned, and the muffling effect is improved.
4, when the mine fan is not in use, it should be placed in the air circulation, preventing moisture, corrosion.
5, motor introduction line peeling joints Naked seven segment is not more than 1.5mm, insulation resistance should not be less than 1 mega, and the inner floor of the fan must be connected correctly.
6. During the handling and installation, it cannot be affected by a large impact, and after the anti-enclosure is deformed, the blade is frozed with the housing.
7, the mine fan should be checked before the use of the fasteners, whether the connection is firm and reliable, whether it is flexible, there is no abnormal sound, etc.
