The effect of use is one aspect that all users are more concerned, because it not only has an important impact on the environment of the venue, but also affects the overall cost of use. ThereforeThe important impact is the effect of judging the use of good judgment from the following aspects, which is also convenient for users to grasp the usage status.
Only by understanding the performance of the fan can we control the fan well.Although this method is a bit complicated to operate, the effect is better, and the most reflecting real situation is one drilling at the entrance and export pipeline of the centrifugal fan to measure the static pressure of the import and exit of the centrifugal fan.Evaluate the operation efficiency of the fan based on the static pressure of the centrifugal fan.This method is simple and does not affect production, but requires professional centrifugal fan knowledge.
For a centrifugal fan that is equipped with a wind door, if the opening of the wind door is less than 95%during runtime, the centrifugal fan must be in an inefficient operation.Regulating the wind door cannot be fully opened, which will have two impacts.First, it will cause uneven air flow of centrifugal fan and reduce the aerodynamic performance of centrifugal fan.Second, there will be stress loss.Calculated at a centrumped fan of 100,000 cubic meters per hour, the loss of about 4KW per 100 Pa pressure is required for each 100Pa pressure loss.
For a centrifugal fan that uses the speed adjustment of liquid puppets, the mechanical loss of the puppet device is 5%when the rated speed is rated, and the loss of mechanical loss at 75%rated speed time has reached 28%.The operating efficiency of centrifugal fans will be much lower.According to the actual usage of the user, the original centrifugal fan is transformed, the pneumatic performance of the centrifugal fan is changed, and the centrifugal fan work at high efficiency.
The type of fan selection is different, and the method of use will naturally be different. This requires users to pay special attention. We need to judge the effect of the fan according to the usage method and requirements. This is more reasonable.During the process, users need to further confirm it.
