Bipolar series Roots blower
A bipolar tandem Roots blower is a unit consisting of two or more standard Roots blowers connected in series, designed to provide higher pressure output. This design allows the gas to enter the intercooler to cool down after being compressed in the first stage, and then enter the second stage for further compression, ultimately reaching the required high pressure level. Bipolar series Roots blowers are widely used in various industrial situations that require large gas flow and high pressure conditions.
Principle
The working principle of the bipolar series Roots blower is based on the single-stage Roots blower, but by connecting two or more single-stage blowers in series to achieve the effect of continuous boosting. Specifically, when the gas enters the first-stage fan, it will be initially pressurized and passes through an intercooler to reduce the temperature to below 40°C; then, the cooled gas enters the second-stage fan and continues to be pressurized until the entire The unit is capable of generating pressures up to 177kPa. There are two three-bladed rotors inside each fan box that turn in opposite directions. Each three-bladed rotor is supported by two bearings and uses a pair of high-precision synchronous spur gears to ensure that the relative position of the two rotors remains unchanged. . The main engine of the two-stage fan can be driven by the same motor through a belt drive or a double-axis extension motor directly connected to ensure the stable operation of the fan system.

Features and Advantages
Energy saving: Thanks to the large volume utilization and high volumetric efficiency, the bipolar series Roots blower can reduce energy consumption while transporting gas.
Stable and reliable: The three-blade rotor structure and reasonable design of the air inlet and outlet in the casing reduce vibration and noise, making the operation more stable.
Strong adaptability: It can adapt to different gas media and working conditions. It is not limited to air, but can also handle various gases such as coal gas and hydrogen.
Easy maintenance: The fan has a compact structure, flexible installation methods, and is easy to use and maintain. Daily maintenance mainly includes cleaning, lubrication and replacement of worn parts.Temperature Control: A built-in intercooling system helps maintain a suitable operating temperature and avoids performance degradation or equipment damage due to overheating.
Gap adjustment: There are strict requirements for internal gaps. During inspection and daily maintenance, these gaps need to be accurately adjusted and checked to prevent friction between the rotor and the wall panel and ensure long-term stable operation of the fan. Usage Scenarios
Bipolar tandem Roots blowers play an important role in many fields due to their excellent performance, especially suitable for applications that have special requirements for gas pressure: Chemical industry: Pressurized transportation of gases required for chemical reactions, such as carbon dioxide recovery and reuse in the production of ammonia and methanol.
Grain processing: As part of the pneumatic conveying system, it is used to transport grains, flour and other materials to improve production efficiency.
Environmental protection engineering: Acts as an aeration blower in sewage treatment plants to provide necessary oxygen supply for microbial treatment.
Mine ventilation: ensure the air quality in underground mines and protect the health and safety of workers.
Tunnel ventilation: maintain good ventilation conditions inside the tunnel, eliminate harmful gases, and improve the driving environment.
Electric power generation: Auxiliary flue gas desulfurization (FGD) systems in coal-fired power plants to help remove pollutants such as sulfur dioxide.
Food and Beverage: Provide carbon dioxide pressurization services in carbonated beverage filling lines to ensure product quality.
