Since our fuel plant was changed to air-supported belt in 1994, it has performed well, has fewer failures, and has less noise. It has a series of superior performance compared with similar belts.
1. The belt runs smoothly and safely
Since the air supported continuously and stably supports the tape running, the material can be smoothly conveyed and the starting resistance is small, and the load start is easy to be realized.
2. Tape running does not run off
Due to the operation of the air supported support tape and the principle of fluid mechanics, the center of gravity of the tape tends to be at the lowest position in the middle of the groove, and can be automatically reset without the need to prevent the deviation device.
3. Less power consumption
The air supported machine consumes less power than the roller machine. The production cases in foreign countries show that the power consumption of the air supported machine is about 50% lower than that of the roller machine. The power consumption of the air supported machine in China is still high, and the energy consumption is about 10% to 20%.
4. Small amount of maintenance
Due to the special structure of the air supported machine, a large number of grooved rollers and brackets are omitted, and the excellent running performance leads to a reduction in maintenance. Compared with the roller machine, the spare parts and maintenance costs can be reduced by about 50%.
5. High productivity
The air supported machine can form the best material loading section. Compared with the roller machine, it can be loaded with 5%~15% material, which is suitable for high speed operation (the belt speed of the general roller machine is 1.25 m/s, and the air supported machine is generally 1.6m/s ~ 2.0 m/s), can improve the transport capacity without increasing the bandwidth.
6. Lightweight tape and long life
The air supported machine has low running resistance and low tension. Lightweight tape can be used. It runs smoothly, does not run off, the tape wears little, the tearing phenomenon rarely occurs, and the service life of the tape is more than doubled.
7. Can be used for large dip arrangements
The air supported machine has continuous gas support, and the material runs smoothly, and its inclination angle is less than the static friction angle of the material and the belt conveyor belt. Just left and right. The actual angle of inclination of the air supported machine can be 18 from the roller machine. Increase to 23. It can also run safely on the left and right.
8. Low noise and few dust
The rotating parts of the air supported machine have less noise, such as isolating the fan, and the pipe plus the silencer is better. Due to the smooth operation, the continuous air supported support has no vibration, and the air velocity at the air outlet of the air supported is very low, and dust does not fly. (Generally, the dust content of the air supported machine working space is about 2II m3~3II∥m3, far lower than the enterprise
The specified standard value is 9 m∥m3).
9. Easy to close
When using an open-air coal handling system, it is easy to make the belt a sealed type, saving space and saving investment in the gallery bridge.
