Comparison Table of Wind Volume and Power of Roots Fan
The air volume and power of Roots blower are key parameters that users need to consider when choosing equipment. Understanding the correlation between air volume and power can help users choose the appropriate fan based on their actual needs. This article will provide a detailed comparison between the air volume and power of Roots blowers, and provide a practical comparison table.
1. Relationship between air volume and power of Roots blower
The air volume (in m3/min or m3/h) of a Roots blower refers to the volume of gas delivered by the blower per unit time, while the power (in kW) refers to the electrical energy required for the operation of the blower. There is a corresponding relationship between air volume and power, usually the larger the air volume, the greater the required power.
2. Factors affecting the relationship between air volume and power
**Factor 1: Fan Design**
There are differences in the design of different models of Roots blowers, and the corresponding relationship between air volume and power will also vary. The designed fan can provide a larger air volume at lower power.
**Factor 2: Operating pressure**
The higher the operating pressure, the greater the power required by the fan. Therefore, under the same air volume, the power of high-pressure fans is usually higher than that of low-pressure fans.
**Factor Three: Rotational Speed**
The speed of the fan directly affects the air volume and power. The higher the speed, the greater the air volume, but the power consumption will also increase.
**Factor Four: Efficiency**
The higher the efficiency of the fan, the greater the air volume provided per unit power. The fan can achieve a larger air output at lower power.
3. Comparison table of air volume and power of Roots blower
The following is a typical comparison between the air volume and power of a Roots blower:
|Airflow (m3/min) | Pressure (kPa) | Power (kW)|
| -------------- | ---------- | --------- |
| 1.5 | 49 | 2.2 |
| 3.0 | 49 | 4.0 |
| 6.0 | 49 | 7.5 |
| 12.0 | 49 | 15.0 |
| 20.0 | 49 | 22.0 |
| 30.0 | 49 | 30.0 |
| 45.0 | 49 | 45.0 |
4. How to choose a fan based on air volume and power
**Step 1: Determine the requirements**
Determine the required air volume and pressure range based on the system requirements.
**Step 2: Refer to the comparison table**
Refer to the comparison table of air volume and power, and select the fan model that meets the requirements.
**Step 3: Consider efficiency**
Choose a fan to reduce operating costs.
**Step 4: Verify Parameters**
Verify whether the air volume and power of the fan meet the requirements in practical applications, and adjust them if necessary.
Through the above introduction, readers can better understand the comparison between the air volume and power of Roots blowers, and thus choose the appropriate blower to ensure the stable operation of the system.
