Use of axial fans and blowers
Dec 28 , 2021
In the cooling fan, the DC fan provides variable flow and the AC fan provides constant flow. In addition to AC power supply and DC power supply, cooling fans are usually classified according to the way air enters and exits the fan. In an axial fan, air enters and exits in the same plane. If the airflow leaves in different planes, this is called centrifugal design or blower. Natural convection cool...

What should be paid attention to when installing centrifugal fan?
Feb 16 , 2022
First of all, when connecting the centrifugal cooling fan, the foundation joint surface, and the inlet and outlet air ducts, they should be adjusted to fit naturally, not forcibly connected, and the weight of the air ducts should not be concentrated on the casing to avoid deformation of the casing and affect the normal operation. The inlet and outlet air ducts of the centrifugal fan should be conn...

How to Repair and Maintain a Centrifugal Fan
Sep 22 , 2022
The basis of a centrifugal fan is a rotating blade wheel called an impeller, which drags the incoming air or gas into a circular motion. It is then pushed out of the fan by the centrifugal force created by the rotation. When entering and exiting the fan, the airflow changes direction. This is the centrifugal fan principle. In order to ensure the normal operation of the fan and improve the service ...

A brief introduction to the blower
Jul 31 , 2023
The definition of blower: It is a general machine that converts the mechanical energy of the prime mover into gas energy and transports gas. In fact, the blower can not produce its own wind, it only uses electricity or the energy generated by the combustion engine oil to drive the fuselage's wind blades, produce wind by changing the air pressure, and change the direction of the wind, and fix the a...

Factors that affect the heat dissipation effect of a cooling fan
Sep 04 , 2023
In the selection of fans, the strength of heat dissipation performance is one of the indispensable considerations. So what are the factors that determine the strength of the fan heat dissipation performance? There are mainly three points: air volume, wind pressure and heat dissipation structure. Air volume: Air volume refers to the amount of air blown by the cooling fan per u...

Disadvantages of centrifugal fan
Sep 11 , 2023
Centrifugal fans have many advantages, but there are also some disadvantages. The following are the disadvantages of several common centrifugal fans: (1) Noise: Centrifugal fans will produce higher noise levels at high speed. This is caused by the friction and compression between the impeller and the air when rotating. (2) Size: Centrifugal fans are usually larger than axial fans with the same air...

Comparison of centrifugal fan drum
Sep 18 , 2023
Forward bent impeller, back bent impeller and radial impeller are all common drum designs in centrifugal fans, and they have some differences in performance, efficiency and application. Here is a comparison between the three types of impellers: 1,Forward-bent impeller: The installation direction of the blade is consistent with the rotation direction of the impeller, which is a forwar...
