Mine fan is a kind of large-scale ventilation equipment used in dam, railway, highway and other places. Once the air volume drops, it is very serious, so we must find out the reason and solve it!
① The mine fan is in the process of transportation, through the air duct, air duct, etc., the tightness of the air duct is not symmetrical, and the cyclone has played a great obstacle. The gas measurement, density and so on are also the elements of the size of the barrier when the wind is trudging.
② When the air duct of the mine fan is installed in the tunnel, it may be due to the irregular placement or the damage of the air duct, such as leakage and fracture, which leads to the decrease of air volume. Why does the air volume of mine fan decrease when it is used?
③ The normal rotary axial-flow fan used in mine fan adopts the double generator type, so the fan pressure is much more than that of single generator. After the fan is started, the stability of external voltage will make the speed of the generator meet, and the fan reference will increase or decrease.
If the mine fan you are using also shows the situation that the air volume decreases after reaching a certain interval direction, you must check according to the above three conditions, determine the causes before you can carry out repair, and then you can deal with this problem. Also, don't forget to check the mine fan regularly, so as to make the incident of mine fan less and less 。
