Centrifugal fan failure in brick kilns
In the brick kilns in the centrifugal fan is important equipment for production, is generally two flow fan, because the kilns ground are dust, dust, in this environment the centrifugal fan will inevitably some dust and dust accumulation, these are as a centrifugal fan, the dust accumulation of uneven wear and by uneven wear to centrifugal fan, balance is destroyed, it will cause the vibration of the centrifugal fan, shorten the service life of the centrifugal fan. To reduce the use efficiency, to take appropriate measures to improve the service life of centrifugal fan and safe production is the most important.
First, the wear of centrifugal fans
The wear of the impeller of the centrifugal fan, generally for erosion wear and chemical wear, friction wear and particle wear, the centrifugal fan work, if the dust particles and the gas flow containing two flow will cause wear. In the kiln dust particles in the enterprise more, in the dust into the impeller of centrifugal fan after interaction with the wall, at the inlet of centrifugal and axial flow in the whole flow, basically is in the air entrainment and the role of inertia, will cause the wear of wall materials.
Two, centrifugal fan wear prevention
1, strengthen the dust removal centrifugal blower, dust is the leading killer of wear of the centrifugal fan, so to improve the efficiency of dust removal equipment, at the same time to reduce the concentration of dust, prevent wear of centrifugal blower.
2, the use of wear-resistant centrifugal fan, in different types of fans, the wear resistance is also different, are generally low speed and single board, hollow vane centrifugal fan is the most wear-resistant.
3, to improve the wear resistance of the blade, the blade surface of the centrifugal fan coated with anti abrasion coating, spray welding wear-resistant alloy material, so that the formation of the fan wear resistant protective layer, thereby improving the wear resistance of the blade.
In 4, the blade centrifugal fan head for serious wear position, so in this position, the installation of a wear-resistant alloy blade, so better make the centrifugal fan with kinetic energy, does not affect the air flow, but also improve the wear resistance.
In the process of centrifugal fan wear is a lot of technology, how to wear, where! This is not false, there are a lot of wear-resistant methods, such as the blade into a solid blade, the use of relatively narrow fan blades, the installation of anti friction shed and guide vanes and other methods are feasible. Mainly according to their own use of the specific circumstances of the centrifugal fan.
