As a consumer, when we buy a product, we often know nothing about it except its function, especially some large mechanical equipment, such as centrifugal fans. At this time, how to install it becomes a big problem, especially if it is not installed, it may not only make the machine unusable, but also may cause certain harm to the human body. At this time, it is very important to know some precautions about installing centrifugal fans. Today, I will use this article to share with you how to install centrifugal fans.

When we buy a centrifugal fan from the manufacturer or in the supermarket, we must first know that to install the centrifugal fan, it should be placed on the foundation or a pair of inclined horns to find a balanced position. For centrifugal fans that need to be assembled on site, the machined surface on the base must be properly protected, and no rust will occur or pairs of inclined pads should be placed on the operating chassis to find a balanced position. 

Secondly, the level of the tight joint between the bearing seat and the base should not exceed 0.2/1000. In addition, a professional level should be used to measure on the football, so that the horizontal horizontal bottom cannot exceed 0.3/1000. , and then use a spirit level to measure on the horizontal mid-section of the bearing housing.

When assembling the centrifugal fan, the rotor shaft should be used as the benchmark to find the position of the casing, and then the horizontal axis and radial gap existing between the air inlet of the impeller and the air inlet of the casing should be reached at high speed. within the scope of the relevant regulations required by the equipment. 

In addition, it is also necessary to check whether the anchor bolts have been tightened. If the clearance value is not specified, it is generally 1/100 of the outer diameter of the impeller. It is especially important to note that the radial clearance must be uniform. When adjusting the distribution, try to reduce the clearance value as much as possible, so as to maximize the efficiency of the centrifugal fan. When the fan is in the right position, the bearing of the fan and the shaft of the motor have different axial degrees. The specific data are: The radial movement cannot exceed 0.05mm, and the angle of inclination cannot exceed 0.2/1000.

If you feel that installing a centrifugal fan is troublesome after reading this article, you can seek professional help. Here you need to pay attention to whether the manufacturer mentions related after-sales service.
