The Roots blower is named after its inventor, the American Roots brothers (Francis Roots and Philonder Roots), which directly reflects the commemoration of the technical contributors. At the same time, its unique working principle and structural features further confirm the rationality of the name. The following analysis will be conducted from three dimensions: naming origins, technical principles, and industry applications:
Naming origin: Paying tribute to inventors and remembering technological contributions
In the mid-19th century, American engineers Francis Roots and Philander Roots designed and invented a device based on the principle of volumetric rotation that could provide stable airflow. To commemorate their technological breakthrough, this device is named "Roots Blower", which is transliterated as "Roots Blower" in Chinese. This naming not only pays tribute to the inventor, but also reflects the industry's respect for technological innovation.
Technical principle: Unique structure, excellent performance
Roots blower belongs to the positive displacement blower, and its core structure consists of two blade shaped rotors. The rotor rotates synchronously in reverse within the cylinder, forming a closed chamber through clearance coordination to achieve forced gas suction and discharge. This design has the following significant features:
Forced air supply characteristics: The gap between the rotor and the casing (usually less than 0.1 millimeters) is achieved through mechanical compression for gas delivery, with a constant air volume that is not affected by changes in pipeline pressure.
Low pressure energy: Under pressure below 1 kilogram, the efficiency is significantly better than that of an air compressor, suitable for scenarios that require stable airflow but low pressure requirements.
Simple and reliable structure: no internal compression process, no direct contact between rotors, minimal wear and maintenance costs, and a service life of tens of thousands of hours.
Industry application: Wide coverage, technological inheritance
Since its invention, Roots blower has become a core equipment in multiple fields due to its stability and economy:
Water treatment industry: used for processes such as aeration and aeration, backwashing, etc., to provide dissolved oxygen for microorganisms and ensure sewage treatment efficiency.
In the field of pneumatic conveying, it serves as a power source to transport granular or powdery materials such as grain, cement, and fly ash, achieving environmentally friendly material transfer.
Industrial Combustion Assistance and Pressurization: Used in industries such as power, cement, and chemical to assist combustion, desulfurization and oxidation, mud mixing, and other processes to improve production efficiency.
Oxygenation in aquaculture industry: By forcing air supply to increase the dissolved oxygen in water, high-density aquaculture is supported, and the modernization of fisheries is promoted.
The name of Roots blower not only carries the history of technological invention, but also reflects its industrial value of achieving performance breakthroughs through structural innovation. Since its invention, its core advantages of "forced air supply and reliable structure" have remained unchanged, becoming an indispensable basic equipment in multiple industries. The deep combination of this naming and technical features also confirms the tradition of "naming classic equipment after people's names" in industrial technology inheritance.
