Detailed explanation of Roots blower model comparison table
introduction
Roots blower, as a type of gas conveying equipment, is widely used in fields such as sewage treatment, pneumatic conveying, and aquaculture. Different models of Roots blowers are suitable for different scenarios, so understanding the comparison table of Roots blower models is crucial for correctly selecting and using blowers. This article will provide a detailed comparison table of Roots blower models to help users understand their performance characteristics.
1. Basic composition of Roots blower models
The model of Roots blower is usually composed of letters and numbers, with letters representing the series or type of blower and numbers representing the specifications or parameters of the blower. For example, 50 represents a 50 type Roots blower, and 100 represents a 100 type Roots blower.
2. Comparison table of common Roots blower models
Here is a comparison table of some common Roots blower models for users' reference:
|Model | Airflow range (m3/min) | Pressure range (kPa) | Motor power (kW) | Speed (rpm) | Noise level (dB (A)) | Inlet and outlet diameter (DN) | Weight (kg) | Material|
|--------|-------------------|----------------|---------------|------------|------------------|-----------------|-----------|------------|
|50 | 0.5-5 | 9.8-58.8 | 0.75-5.5 | 1450-2900 | ≤ 75 | 50 | 50-70 | Cast iron/stainless steel|
|80 | 5-10 | 9.8-58.8 | 2.2-7.5 | 1450-2900 | ≤ 75 | 80 | 80-120 | Cast iron/stainless steel|
|100 | 10-20 | 9.8-58.8 | 5.5-15 | 1450-2900 | ≤ 75 | 100 | 150-200 | Cast iron/stainless steel|
|125 | 20-30 | 9.8-58.8 | 11-22 | 1450-2900 | ≤ 75 | 125 | 200-300 | Cast iron/stainless steel|
|150 | 30-50 | 9.8-58.8 | 18.5-37 | 1450-2900 | ≤ 75 | 150 | 300-500 | Cast iron/stainless steel|
|200 | 50-100 | 9.8-98 | 37-75 | 1450-2900 | ≤ 85 | 200 | 500-700 | Cast iron/stainless steel|
|300 | 100-200 | 9.8-98 | 75-110 | 1450-2900 | ≤ 85 | 300 | 700-1500 | Cast iron/stainless steel|
3. Instructions for using the model comparison table
**Determine air volume and pressure requirements: Users should determine the required air volume and pressure based on the actual application scenario, and then refer to the model comparison table to choose the appropriate fan model.
**Select motor power * *: Choose the appropriate motor power based on the requirements of air volume and pressure. The higher the power, the stronger the air volume and pressure capacity of the fan.
**Consider other factors * *: In addition to air volume, pressure, and power, users also need to consider factors such as fan noise level, material, weight, etc. to ensure that the fan can meet usage requirements and have a longer service life.
4. Application scenarios
Roots blower is suitable for the following scenarios:
-Wastewater treatment: Used for oxygen transport in aeration tanks to improve wastewater treatment efficiency.
-Pneumatic conveying: used for conveying powdered or granular materials, such as cement, grains, etc.
-Aquaculture: Used for oxygenation of fish ponds to improve the yield and quality of aquaculture.
-Vacuum packaging: Vacuum packaging equipment used in industries such as food and medicine.
5. Selection suggestions
When choosing a Roots blower, users should determine the air volume and pressure range according to their actual needs, and choose the appropriate motor power and speed. At the same time, factors such as the noise level, material, and weight of the fan need to be considered to ensure that the fan can meet usage requirements and have a longer service life.
6. Conclusion
The comparison table of Roots blower models is an important basis for selecting and using blowers. By understanding its model comparison table, users can better choose and use Roots blowers to ensure their performance in practical applications.
