 FBCDZ Series Mine Explosion-proof axial flow fan

1., the use of the fan
 
FBCDZ series coal mine ground explosion-proof and extractable counter-rotating axial flow fan is the latest energy-saving axial flow main fan which is in the leading level of our country at present. It can be used in ventilation of coal mine and metal mine, chemical mine, tunnel and civil air defense project, and it can be used in coal mine and metal mine, chemical mine, tunnel and civil air defense project. Also widely used in metallurgy, chemical, textile, building materials and other industries ventilation and ventilation.
 
2, the characteristics of the fan
 
This series is of high efficiency, energy saving, low noise and large air volume. It has narrow hump area and steady wind pressure, weak surge phenomenon and steady air flow. It can adapt to the change of mine production and keep running under the condition of higher efficiency when the ventilation parameters change. 4) according to the production needs, the cyclone machine can also be operated on a single machine. The operation of the cyclone machine can increase the air volume by 45-70 and increase the wind pressure by 100- 1922. The fan adopts reverse wind, and the reverse air volume can reach more than 60% of the normal air volume.

3. Supporting components:
 
Silencer the series of silencers are specially designed for fan silencers, which adopt the combined structure of duplex and silencing walls. The silencing technology is the leading in the country and the noise reduction effect in practice is remarkable. The problem of high noise at the outlet of axial flow fan is solved, so as to ensure that the user has a good environment. The performance of fan is fully considered in the design, the internal structure of silencer is optimized, and the resistance loss is reduced to the minimum. The series of diffusion towers are designed to be streamlined to ensure that the direction of the air flow does not change in the course of change. Its function is to change the wind.The flow direction of the protection of the surrounding environment can also reduce noise; (two) to reduce the dynamic pressure loss of the fan into effective pressure, improve the fan efficiency. (3), the company designed the throttle damper installed between the exhaust outlet wind tunnel and fan collector. Open the fan, by the wind the suction pump pressure; after the shutdown, depending on the weight of the gate closed. Natural negative pressure produced another typhoon machine work the door tightly suck less. Other than the air leakage in coal mine, not only saves the lifting equipment, simple structure, and convenient management. (4), on-line monitoring and early warning system in wind turbine in operation, the microcomputer can clearly reflect theAnd record the dynamic curve, wind pressure, air volume, wind speed, bearing and stator temperature and current, voltage, vibration and other parameters of the fan, and can record files and fault alarm, and can at any time from the microcomputer out of the fan all operation records.
 
The main features are as follows: 1). The simplest structure of fan with direct connection of motor and impeller has changed the complicated structure of the current coal mine pull-out axial flow ventilation and all of which adopt belt drive or long shaft drive. 2) FBCZ series coal mine explosion-proof and pull-out axial flow fan is installed in the outside of the motor with a fully closed type and a certain pressure strength airtight heat sink and air pressure balance pipe, which makes the motor always operate in the gasless air. It meets the requirements of relevant explosion-proof regulation in coal mine. 3)FBCZ series explosion-proof and pull-out axial flow ventilator is a single-stage working wheel structure, and the fan and diffuser are provided with rear guide vane in order to improve the quality of the system.Static pressure efficiency. 4), the fan can reverse the counterwind, its backwind volume can reach 65% of the positive air volume, it does not need to set up another backwind channel, it has the advantages of saving capital construction investment and high speed of backwind. 5). The blade mounting angle of the impeller can be adjusted. The blade angle can be adjusted according to the requirement of production. The fan adopts special design and the performance curve has no hump and can operate stably under any network resistance.
