Does the dust on the centrifugal fan have a big impact on the performance of the equipment?

It will definitely have an impact, the centrifugal fan should do a good job of surface cleaning, especially the air inlet and outlet of the fan can not have debris, and it is best to regularly remove the dust in the fan and pipe. In addition, the instructions given by the wonderful fan emphasize that the filter device or dust collector should be installed before the air inlet of the fan, and if the air inlet is uneasy about the equipment, a protective net must be added to prevent foreign objects from being inhaled and damaged to the impeller.

Impactful. More dust will increase the resistance of the runner, which is less efficient.

Centrifugal fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas, and it is a driven fluid machine. Centrifugal fans are widely used for ventilation, dust removal and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced air for boilers and industrial furnaces; cooling and ventilation in air-conditioning equipment and household appliances; drying and selection of grains; Wind tunnel wind source and hovercraft inflation and propulsion, etc.

Generally, the surface of the fan impeller is covered with dust, which will affect the balance of the fan, if there is vibration, please clean the dust as soon as possible, if there is still vibration after the dust is cleaned, the balance correction is required. If the dust is serious, it will have a certain impact on the air volume and air pressure of the fan.

For dust removal with large dust and high humidity, the dust removal fan should use a full-open impeller, that is, the impeller does not have a front cover and a back cover, the blades adopt radial straight blades, and there must be a cleaning window on the side of the volute. Wet dust cleaning, compressed air can not be cleaned, must be cleaned with high-pressure water gun. It is better to replace the dust removal fan directly than to change the motor frequently, and the 3kw dust removal fan** will not be much more expensive than the motor.

Go to the manufacturer of the dust collector to find out, there is a kind of wet dust collector should be used on this kind of fully open impeller and open the fan with the cleaning window, and the cleaning window can be opened without yourself. Maybe such a small wet dust collector may not be available, so you can only customize a fan with a fully open impeller.

If you can't find such a fan, and there is nowhere to customize, the only way is to remove the volute front cover plate at the fan inlet, and you can see the impeller after the volute inlet front cover plate is removed. This work may be done every three or five days, and it is indeed a bit troublesome. If your current fan impeller does not have a front cover plate is the best, you can cut a rectangular window on the volute inlet front cover plate by yourself, and then use a larger steel plate and a sealing rubber to screw it on, as a movable cleaning window, and the water gun can be directly flushed to the blade during cleaning.

Since the volute is stationary, as long as the cleaning window does not leak, this will not have any effect on the use of the fan.

As long as the diameter of the driving wheel and the driven wheel are the same, of course, the speed can be kept unchanged. However, after changing to belt drive, the motor is isolated, but the fan must be changed to a structure supported by two bearings, although the motor bearing is not easy to be damaged, but the two bearings of the fan must also be replaced frequently. If you'd rather replace the wind turbine bearings, this is a way to reduce some of the damage.

1. The fan is open to facilitate the removal of dust.

2. The fan is installed with a shock-absorbing base.

3. Correct the fan blades.

4. Frequency converter can be added if conditions permit, and the speed can be reduced when the workload is small.
