What is a Roots Blower and How Does It Work?
Roots blowers, also known as rotary lobe blowers, are mechanical devices used for delivering a high volume of air or gas at relatively low pressure. These blowers find applications across various industries for tasks ranging from pneumatic conveying to wastewater treatment. In this article, we'll delve into the working mechanism, applications, advantages, and limitations of Roots blowers. History of Roots Blower The Roots blower was invented by brothers Philander and Francis Roots in the 19th century. Originally designed for use in blast furnaces, its efficiency and versatility led to its adoption in various industries, contributing significantly to industrialization. Components of Roots Blower Rotors The core of a Roots blower consists of two rotors, typically made of high-strength steel. These rotors are mounted on parallel shafts within the blower casing and are synchronized via timing gears. Casing The casing houses the rotors and creates airtight chambers for compression. It ...
