Roots blower is used to provide the air source in the pneumatic conveying, and the air source equipment is at the core of the pneumatic conveying system and is the most important equipment. The delivery air volume and pressure provided by it effectively ensure the effectiveness and reliability of the system. Due to the different pneumatic conveying methods, places of use, conveying distances, required conveying capacity, and the physical properties of the materials being conveyed, there are many types of compressors for the pneumatic equipment of the pneumatic conveying system that can be selected. Air compressors, roots blowers, roots vacuum pumps, centrifugal fans, etc.
Structural features of environmental protection pneumatic conveyance roots blower:
1. Low noise. The inlet and exhaust vents of the fan adopt a spiral shape, so that the intake and exhaust processes are sequentially cut in according to the direction of the spiral line, which avoids the pulsating noise and vibration that instantly erupt when the exhaust fan of the old fan exhausts. This series of fans use a composite anti-muffler silencer to further reduce noise.
2. High adiabatic efficiency and volumetric efficiency, thus saving energy. The fan rotor adopts advanced compound curve, the meshing is more reasonable, and the volumetric efficiency is increased.
4. Small vibration. Although the rotor is precisely machined, it is in equilibrium. However, high-precision dynamic balancing equipment is still used for balancing. Therefore, the fan operates with almost no vibration.
5. The use of high-precision, high-hardness synchronous gears not only extends the life of the fan, but also effectively reduces noise.
6. This series of fans adopt bearings imported from Japan or Germany and rubber belts imported from South Korea or Taiwan, making the product quality more reliable.
7, the output air is clean, does not contain any oil and dust, the fan seal structure is reasonable, so that oil can not enter the casing, so the air is clean.
Application range of pneumatic conveying roots fan
Roots blowers for pneumatic conveying are widely used in petroleum, chemical, metallurgy, food, building materials and other departments. In recent years, pneumatic conveying roots fans have been widely used in thermal power plant fly ash, chemical powder, granular materials, fine chemical raw materials, cement, raw grain and other transportation projects. It has many advantages such as low energy consumption, high degree of automation, long-term continuous operation, and no environmental pollution. It is an advanced technology most suitable for bulk material transportation. The pneumatic conveying system equipment mainly includes roots fans, compressors, rotary feeder , Reversing valve, slide valve, cyclone separator, instrument, etc.
