AC Centrifugal Fan How to Do Dynamic Balance
In the new production line, various models of centrifugal fans installed capacity of the production line between 30% and 40% of the total power, to strengthen the maintenance and maintenance of online AC centrifugal fans, this is very important.
In particular, serious wear of the fan impeller, resulting in unbalanced fan rotor, resulting in the entire fan amplitude increased, seriously affecting the normal operation of production.
Therefore, how to do the dynamic balancing for the fan at the construction site and remove the imbalance factors, in the years of fan maintenance management, Miracle summarized a set of effective simple diagramming methods that are used to find out the location of the impeller light point method, and add counterweight at the location of the light point, in order to clear the fan imbalance.
Fan rotor to do dynamic balancing, the key is to find out the location of the impeller light point and to determine the quality of the balance block used to find the balance of the graph method, the specific steps are as follows:
(1) open the fan, stable operation, in the most reflect the fan vibration of the M point (such as the bearing seat, etc.), using a vibration meter to measure its amplitude A0, recorded after the stop
(2) the impeller before the disk (or after the disk) circumference of 3 equal parts, respectively, like 1 point, 2 points, 3 points
(3) clip the pre-made clip block P at point 1 (according to the size of the fan impeller to determine its mass, generally mp = 150 g ~ 300 g), repeat step 1, measure the amplitude of M point A1
(4) replace the position of the clamping block P to 2 and 3 points, repeat step 3, and measure the amplitude of the M point A2, A3 in turn
(5) the diagram to A0 for the radius of the circle, the center of O, the circle will be 3 equal parts, respectively, as O1 points, O2 points, O3 points; O1 as the center of the circle, A1 as the radius of the arc; O2 as the center of the circle, A2 as the radius of the arc; O3 as the center of the circle, A3 as the radius of the arc of the above three arcs are intersected at B, C, D three points
(6) for the type of BCD center O4, O4 point that is the light point, connect OO4 and extend the intersection of the circle O in O5 point, O5 point that is to add the counterweight iron block point side to get OO4 length L, then O5 point counterweight mass m with = mp × A0 /2L
(7) in the fan impeller before the disk (or after the disk) circumference to find the actual O5 point location, the counterweight m with the iron block welded firmly, so far, the centrifugal fan for balancing completed.
How the Smoothness of AC Centrifugal Fans is Achieved?
Miracle AC centrifugal fan after so many years of development has been deep into the market, more and more industry sectors widely used, but also in exchange for applause and recognition.
Then as one of the fan types, AC centrifugal fans in helping users to achieve better ventilation purposes at the same time also often faced with the problem of conventional problems.
For example, the smoothness of the AC centrifugal fan will not always play normally, so you must pay extra attention to this point when choosing, so Miracle AC centrifugal fan in the end how to do the smoothness of this point? What are the common technical means?
AC Centrifugal fan in the use of the process, the pressure and flow generated is an important factor affecting its smoothness, so we must pay attention to the pressure and flow changes it produces when using the centrifugal fan.
Usually, the AC centrifugal fan flow will change with the AC centrifugal fan rotational speed changes, if the wider the range of pressure selection, then the choice of flow will be through the speed to meet the needs of users, as the impeller in the body of the AC centrifugal fan operation does not produce friction, then there is no need for lubrication, and the exhausted gas will not contain oil.
It can be seen that the smoothness of the AC centrifugal fan has a direct relationship with almost every component, which requires the user to safeguard the effectiveness of each component in the process of using the AC centrifugal fan to provide the most basic guarantee for the smoothness of the fan.
