Frequently Asked Questions About Explosion-Proof Centrifugal Fans
When it comes to explosion-proof centrifugal fans, I don’t think anyone would be surprised. I’ve previously shared a lot of information about this equipment.
To help you better understand explosion-proof centrifugal fan systems, we’ve compiled a few questions to share with you.
Let’s take a look at the details. One question is: Given that the static pressure, output, and speed of an explosion-proof centrifugal fan are known, can this information be used to calculate the air flow rate?
First, the answer to this question is “yes,” but the calculation must follow a specific formula. That is, q = n × 1000 × ηa × 3600 × η / p.
In this formula, q represents the air flow rate, n is the shaft speed, ηa is the mechanical transmission efficiency, and η denotes the fan efficiency. Additionally, p represents the fan’s pressure.
The second question is: in practical use, why are explosion-proof centrifugal fan units referred to as soft-characteristic fans?
This is because, during operation, the greater the system resistance, the lower the actual airflow; hence, they are also called soft-characteristic fans.
The third question: what are static balance and dynamic balance? How do they affect explosion-proof centrifugal fans?
Static balance refers to whether there is relative movement between the impeller and the main shaft of the explosion-proof centrifugal fan unit while at rest, and whether friction occurs.
Dynamic balance refers to whether the fan’s impeller wobbles back and forth during rotation and whether the machine’s stability can be ensured.
The above are some common questions shared by everyone. I believe that once these concepts are understood, no one will have any doubts. It would be great if you can make good use of explosion-proof centrifugal fans in the future.
