What are the types of Roots blowers?
Roots blower, as a widely used equipment in the industrial field, has various types and is suitable for different working conditions and needs. Understanding the types of Roots blowers can help users choose the appropriate blower based on their actual application scenarios. This article will provide a detailed introduction to the main types and characteristics of Roots blowers.
1. Classified by working principle
Roots blowers can be divided into volumetric Roots blowers and centrifugal Roots blowers based on their working principles.
-Volumetric Roots blower: By rotating two interlocked rotors inside the casing, gas is drawn in from the inlet and compressed before being discharged. Its characteristics are stable flow, wide pressure range, simple structure, and easy maintenance.
-Centrifugal Roots blower: It generates centrifugal force through the rotation of the impeller, which draws gas in from the center and discharges it along the edge of the impeller. Its characteristics are high flow rate, low pressure, and suitable for high flow situations.
2. Classify by pressure
According to the working pressure of Roots blowers, they can be divided into low-pressure Roots blowers, medium pressure Roots blowers, and high-pressure Roots blowers.
-Low pressure Roots blower: The working pressure is generally below 9.8 kPa, suitable for pneumatic conveying, aquaculture and other occasions.
-Medium pressure Roots blower: Operating pressure between 9.8 kPa and 49 kPa, suitable for sewage treatment, vacuum packaging, and other applications.
-High pressure Roots blower: With a working pressure above 49 kPa, it is suitable for high-pressure pneumatic conveying, high-pressure vacuum systems, and other applications.
3. Classify by traffic
According to the flow rate of Roots blowers, they can be divided into small Roots blowers, medium Roots blowers, and large Roots blowers.
-* * Small Roots blower * *: flow rate below 50 cubic meters per minute, suitable for small sewage treatment plants, small pneumatic conveying systems, etc.
-Medium sized Roots blower: flow rate between 50 and 200 cubic meters per minute, suitable for medium-sized sewage treatment plants, medium-sized pneumatic conveying systems, etc.
-Large Roots blower with a flow rate of over 200 cubic meters per minute, suitable for large sewage treatment plants, large pneumatic conveying systems, etc.
4. Classify by material
According to the material of Roots blowers, they can be divided into cast iron Roots blowers, stainless steel Roots blowers, and aluminum alloy Roots blowers.
-Cast iron Roots blower: Suitable for general working conditions, with low cost and good durability.
-Stainless steel Roots blower: Suitable for corrosive gases or high humidity environments, with strong corrosion resistance.
-Aluminum alloy Roots blower: Lightweight, suitable for situations where equipment weight needs to be reduced.
5. Classify by application scenario
According to the application scenarios of Roots blowers, they can be divided into sewage treatment Roots blowers, pneumatic conveying Roots blowers, aquaculture Roots blowers, and vacuum packaging Roots blowers.
-Roots blower for sewage treatment: used for oxygen supply and agitation in aeration tanks of sewage treatment plants.
-Pneumatic Conveyor Roots Fan: Used for conveying powdered and granular materials.
-Aquaculture Roots blower: Used for oxygenation in aquaculture farms to increase the oxygen content in water bodies.
-Vacuum packaging Roots blower: used in vacuum packaging systems to extract air from packaging containers.
By understanding the types of Roots blowers, users can choose the appropriate blower according to their actual needs, ensuring the operation and long-term use of the equipment.
