What is a Roots Blower:
A Roots blower is a twin-rotor positive displacement compressor in which the axes of the two rotors are parallel to each other. Each rotor consists of an impeller combined with a shaft, and there are minimal clearances between the impellers, and between the impellers and the casing and end plates, to prevent contact. The impellers, together with the casing and end plates, enclose a fixed displacement volume whose size remains unchanged during rotation. The two rotors are driven by a prime mover through a pair of timing gears, rotating in opposite directions at equal speeds, pushing the inhaled gas from the suction port to the discharge port without internal compression, thereby completing the gas conveying process.
Product Features:
The Shangu series products are a new line of products independently developed based on the introduction and absorption of advanced technical features of various domestic and international Roots blowers. During the R&D process, technologies such as CAD and CAPP were utilized, along with advanced CNC computer-aided machining technology, ensuring the manufacturing precision and practical performance of Shangu series blower products, which have been widely applied in various important sectors of the national economy.
- Each blower model comes with a performance table and standard specifications, making it easy to select the appropriate blower model.
- Including accessories, the main body of the blower is standardized, with a well-established mass production system that can meet your requirements at any time.
- The product adopts an imported spiral noise shielding structure and exhaust gas premixing technology, while the gears use high-precision hardened tooth surfaces, resulting in significantly lower operating noise compared to similar products.
- The rotors are precision components that have undergone full machining and are completely dynamically balanced during manufacturing, resulting in virtually no vibration.
- The product incorporates multiple new structural designs, making the entire unit compact, small in size, light in weight, and aesthetically pleasing in appearance.
- The conveyed air is clean and free of any oily dust.
