The field of application of local ventilation fans
Local ventilation fans occupy an important place among the devices for safe handling at the enterprises of mining and coal mining industry. Their goal – is the timely removal of mine gas and dust, temperature and humidity decrease in underground mines. That is why local ventilation fans are among the main components of the mine ventilation systems. Fans of local ventilation VME/VMP (ВМЭ/ВМП) are used for ventilation of blind mining coal and ore mines. Fans of the VOE (ВОЭ) series are oriented on the organization of terrestrial space ventilation shafts. Furthermore, they can be successfully used on grain procurement stocks and load / unload grain systems and for air venting of granaries. Local ventilation fans ВМЭ are made in explosion-proof version. VMP (ВМП) series fans are equipped with air-powered drive, they are designed for dangerous dust and gas categories of works. Ventilators are connected to the ventilation systems via a system of rigid or flexible piping. Piping length can be up to 2.5 km, while the diameter may range from 400 mm to 1200 mm. With the using a fan of local ventilation system designed intake or supercharge ventilation.
The main characteristics and design of local ventilation fans
Temperature regimes, in which local ventilation fans can operate are in the range from - 40ºС to + 40ºС. The air which is pumped over by fans may have a density of up to 1.2 kg / m3 and the dust content in it should not exceed 50 mg/m3. Local ventilation fans allows consistently connect two or more fans, if necessary, in the case of very long airways. This will provide the necessary power of air pump. Electric engines which are used in fans VME (ВМЭ), are explosion-proof with the degree protection of envelope IP54. The bearings used in the design of fan are closed type. They can work for a long time without replenishing of grease. Local ventilation fans belong to the class of axial, single-stage fans. The fan series VOE (ВОЭ) has dust-moisture-proof body with removable electric motor. Input and outlet mainfolds are equipped with anti-stall device. Blades of the rotor of local ventilation fans are made of non-combustible materials, and the rotor itself - made of sheet steel. Stable operation of the fan is possible only if they are installed horizontally. The deviation from the horizontal axis of the fan is allowed not more than 30º. Local ventilation fans VME (ВМЭ) are equipped with heat and vibration protection. They are designed for manual and automatic control and can be operated in normal and reverse modes. In the case of emergency during operation, such as short-term miss of voltage, provided the supply of sound and light signal to the controller. Design of local ventilation fan VMP (ВМП) has in its composition nozzle unit with three inputs. The different pressure characteristics and different modes of fan operation can be obtained when the device is connected to one, two or three nozzles.
Advantages of local ventilation fans
The advantages of local ventilation fans include their efficiency. Their dimensions and design allows to use them even for small openings. At large extent of the pipelines length it is possible to connected two and more fans in series. Local ventilation fans are designed for long, continuous operation. It is possible to complete them with sound dampers. Fans are low cost and not complicated to operate.
