Product introduction :
HDSR three-lobe Roots blower is a new product automatically developed by our company on the basis of the advanced technical characteristics of various types of Roots blower at home and abroad. The development of the product uses advanced CAD laying design and advanced processing technology to ensure the performance of the blower, and has been widely used in the field of national economy: sewage treatment, flour, aquaculture, pneumatic conveying, electric power, cement and other industries. Products wide range of air volume, classification dense, high pressure, nearly 20 models, more than 100 kinds of specifications.
Design and Operation :
（1）Lobe Configuration: Unlike the traditional two-lobe design, a three-leaf roots blower has three lobes or vanes. These lobes rotate inside a specially shaped housing to move air or gas. This three-lobe design allows for smoother airflow and can reduce pulsations compared to two-lobe models.
（2）Positive Displacement: Roots blowers operate on the principle of positive displacement. As the lobes rotate, they trap a fixed volume of air or gas and force it out of the blower, creating a steady and continuous flow. This makes them suitable for applications requiring constant air flow.
（3）Construction: The blower typically consists of two rotors with three lobes each, housed in a casing. The rotors are synchronized to prevent contact, which helps to minimize wear and tear and ensures efficient operation.
Advantages :
(1）Positive displacement blower, stable pressure and capacity.
（2）Three lobe type roots blower, high efficiency, energy saving.
（3）Good sealing treatment, oil free, no oil pollution to conveying medium.
（4）Imported accessories in high quality, ensuring the long service life of whole set roots blower.
（5）Each size roots blower has in storage, short delivery time is available.
（6）Both whole set roots blower and bare shaft blower can be provided.
（7）Every roots rotary blower has been tested before delivery, each one of them can work efficiently.
（8）Wide range of pressure rise and flow rate roots air blower.
（9）We can provide ISO9001, CE and EAC certification for roots blower.
The main parts of HDSR (shell, end cover, shaft, impeller) are made by CNC machining center. The main outsourcing uses NSK,FAG bearings, famous brand gear, American Gate belt, Taiwan TTO rubber oil seal, which improves the efficiency of the blower and reduces the noise, and extends the service life of the blower to more than 10 years!
Application :
Roots blowers, known for their positive displacement mechanism, are widely used across various industries due to their reliability and efficiency in moving air and gases. Here’s a look at some of the key applications of our HDSR roots blowers in different sectors:
1. Wastewater Treatment
Aeration: Roots blowers are used to supply air to aeration tanks in wastewater treatment facilities. This helps in maintaining aerobic conditions, which are crucial for the microbial breakdown of organic matter.
Sludge Handling: They also help in conveying sludge and facilitating the mixing and agitation required for effective treatment.
2. Pneumatic Conveying
Bulk Material Transport: In industries such as food processing, pharmaceuticals, and chemicals, roots blowers are used to transport bulk materials through pipelines. They can handle powders, granules, and pellets efficiently.
Powder Handling: For industries dealing with fine powders, roots blowers provide a controlled and steady flow, minimizing dust and spillage.
3. Industrial Processing
Combustion Air Supply: In combustion processes, roots blowers can supply the necessary air to burners and furnaces, ensuring efficient fuel combustion.
Cooling and Ventilation: They are used in various cooling systems to move air and maintain temperature control in manufacturing processes.
4. Chemical and Petrochemical Industries
Gas Transfer: Roots blowers are used to transfer and compress gases in chemical processing, including handling hazardous or corrosive gases.
Process Air Supply: They provide air for various chemical reactions that require precise control of air flow and pressure.
5. Food and Beverage Industry
Packaging: In packaging operations, roots blowers are used to create and maintain vacuum conditions or to fill packaging with inert gases to extend shelf life.
Fermentation: They help in supplying air or oxygen to fermentation tanks where yeast or bacteria cultures are grown.
6. Mining and Quarrying
Ventilation: Roots blowers are used to provide ventilation in underground mines and quarries, ensuring a supply of fresh air and the removal of harmful gases.
Dust Control: They help in controlling dust by supplying air for dust suppression systems.
7. Pharmaceuticals
Clean Room Environments: In pharmaceutical manufacturing, roots blowers are used to maintain clean room conditions by providing controlled air flow and pressure.
Material Handling: They are employed to handle sensitive materials that require precise flow and containment.
Overall, the versatility and reliability of roots blowers make them valuable across a broad spectrum of industries, wherever consistent air or gas flow is required.
8. In the cement manufacturing process, the main application of Roots blower has two aspects:
(1) Pulverized coal transport: Pulverized coal is blown into the combustion furnace by Roots blower for combustion.
(2).Flue gas treatment: A certain amount of gas is generated in the cement production process, which requires flue gas treatment, and Roots blower is one of the core equipment of the flue gas treatment system. It can help move smoke and dust and send the smoke into the electrostatic precipitator for purification.
9. Aquaculture
Providing oxygen and improving water bodies: aquaculture often requires a large amount of oxygen, and the oxygen provided by Roots blowers can promote the oxygen balance in the water body, improve the water quality, and promote the growth and health of aquaculture. And it can improve the improvement of the water body through the air flow, improve the oxygen balance in the water body and remove pollutants.
