VVM-8

Mine fan with electric drive VVM-8

The VVM-8 counter-rotating shaft mine fan with an explosion-proof electric drive is designed to ventilate dead-end mines with a cross section of 16 to 35 m2 at an air density of 1.3 kg / m3, a temperature of 268 to 308 K, dust content of up to 50 mg / m3 and relative humidity up to 95% (at a temperature of 298 K).

During operation, the fan is installed in a horizontal position with a permissible deviation of the fan axis from the horizontal of not more than ± 30 °. A distinctive feature of this type of fan from VME-2 fans is a significantly higher created head with a smaller nominal diameter and greater efficiency, due to the absence of losses in rectifying devices and loss of twisting at the fan outlet. If necessary, VVM-8 fans can operate with one engine turned on, which increases the efficiency of the machine. At the request of the consumer, the fans can be supplied with voltage 380/660 V and 660/1140 V.

Advantages:

• modern aerodynamic design with high pressure characteristic.
• thermal protection with the ability to turn off the fan when the normal temperature of the motor winding is exceeded.
• fan blades are made of non-combustible materials.
• profitability.
• at the request of the customer, the fan can be equipped with a silencer.
