The piping system is a vital component of Roots blower operations, as its design directly influences the system’s efficiency, energy consumption, and service life. Many industrial enterprises face challenges like excessive pipeline resistance, air leakage, fan vibration, and shortened equipment life due to unreasonable piping design, which increases operational costs and disrupts production stability. Shandong Jianyu Heavy Industry addresses these pain points through in-depth research and optimized design, creating a scientific, standardized piping solution that significantly enhances the stability and energy-saving performance of Roots blower systems.
Shandong Jianyu boasts a professional piping design team with years of experience in Roots blower piping design and installation. Team members are well-versed in the performance characteristics of various Roots blowers and the requirements of different application scenarios. Combining the technical parameters of the company’s own Roots blower products and users’ actual needs, they have developed detailed piping design standards covering material selection, diameter determination, routing design, connection methods, and accessory configuration, forming a complete and systematic design system.
In material selection, Shandong Jianyu adheres to the principle of “adapting to working conditions and ensuring durability.” Based on the Roots blower’s exhaust temperature, pressure, and conveyed medium, the company recommends suitable pipeline materials. For general working conditions, high-quality steel pipes with strong pressure-bearing capacity, high-temperature resistance, and corrosion resistance are recommended to withstand long-term high-pressure operation and prevent pipeline burst or leakage. For special conditions involving corrosive gas conveyance, anti-corrosion pipelines such as stainless steel or FRP pipes are proposed to extend the pipeline system’s service life.
In terms of diameter and routing design, the company strictly controls pipeline diameter to ensure it is no smaller than the Roots blower’s air intake and exhaust diameter, avoiding excessive resistance and reduced air supply efficiency caused by undersized pipes. Pipeline routing is designed to be short and straight, minimizing the number of elbows and tees; large-radius elbows are used for unavoidable bends to reduce local resistance. Additionally, pipelines are reasonably arranged to avoid interference with other equipment and facilitate later maintenance and inspection.
For pipeline connection and accessory configuration, Shandong Jianyu sets strict standards. Connections must be tight and airtight, with flange connections used for key parts to ensure firmness and easy disassembly and maintenance. Supports are installed at appropriate positions to prevent pipeline deformation caused by self-weight and gas pressure. Elastic joints are mounted on both the inlet and outlet sides of the fan to eliminate the impact of pipeline vibration and thermal deformation on the fan, facilitating connection and adjustment.
A check valve is installed on the fan’s exhaust side to prevent high-pressure gas from flowing back and damaging fan components due to fan reversal, with the requirement that the check valve be mounted on horizontal pipelines for normal operation. An air release valve is also installed to allow timely pressure relief during fan start-up and shutdown, avoiding excessive pressure impact on the fan and pipelines. A filter is installed on the air inlet pipeline to prevent dust and impurities from entering the fan, which would cause wear to rotors and cylinders and shorten service life.
To date, Shandong Jianyu’s Roots blower piping design solution has been widely applied in wastewater treatment, pneumatic conveying, cement production, and other industries. It has effectively solved the problems of unreasonable piping design, reduced system energy consumption by 15%-25%, and extended the service life of fans and pipelines by more than 30%, earning high recognition from users.

Wastewater Aeration Roots Blower: Shandong Jianyu Helps Environmental Protection Upgrade
With the continuous upgrading of national environmental protection standards, the wastewater treatment industry is facing higher requirements for treatment efficiency and emission indicators. The aeration system is the core of the wastewater treatment process, and the performance of the Roots blower, as its power source, directly determines the wastewater treatment effect. Focusing on the R&D and manufacturing of Roots blowers, Shandong Jianyu Heavy Industry has developed a special Roots blower for wastewater aeration systems, effectively solving the problems of low aeration efficiency, high energy consumption, and unstable operation of traditional aeration systems, and promoting the green and efficient development of the wastewater treatment industry.
Shandong Jianyu’s independently developed special Roots blower for wastewater aeration is designed for the characteristics of wastewater treatment scenarios, such as high humidity, high corrosion, and large air volume demand. The fan adopts a high-strength cast iron cylinder and rotor, which have strong corrosion resistance and wear resistance, enabling it to adapt to the harsh working environment of wastewater treatment plants. At the same time, the company optimizes the internal flow channel of the fan to reduce flow resistance, improve air delivery efficiency, and ensure stable and sufficient air volume for the aeration system.
In terms of energy saving, the special Roots blower for wastewater aeration is equipped with an intelligent frequency conversion control system, which can automatically adjust the fan speed according to the dissolved oxygen content in the wastewater. When the dissolved oxygen content meets the standard, the fan reduces speed to save energy; when the dissolved oxygen content is insufficient, the fan increases speed to ensure the aeration effect. Compared with traditional fixed-speed Roots blowers, it has obvious energy-saving effect, with a single wastewater treatment plant saving 200,000 to 500,000 kWh of electricity annually, greatly reducing the enterprise’s operational costs.
In addition, the blower has the characteristics of low noise and low vibration. Equipped with professional silencers and shock absorbers, it effectively reduces the noise generated during operation, making the fan noise meet national environmental protection standards and improving the working environment of the wastewater treatment plant. The fan adopts a sealed structure design to prevent the leakage of harmful gases in the wastewater, ensuring the safety of operators and meeting the industry’s environmental protection and safety requirements.
Shandong Jianyu not only provides high-quality special Roots blowers for wastewater aeration but also offers a full set of supporting services, including on-site investigation, program design, installation and commissioning, and after-sales maintenance. The company’s professional technical team formulates personalized aeration solutions according to the scale of the wastewater treatment plant and the water quality, ensuring that the fan perfectly matches the aeration system to achieve the best treatment effect. It has established a complete after-sales service system, with professional after-sales personnel on call 24 hours a day to provide timely maintenance and repair services, ensuring the continuous and stable operation of the fan.
Up to now, the special Roots blower for wastewater aeration of Shandong Jianyu has been widely applied in municipal wastewater treatment plants and industrial wastewater treatment projects (such as chemical, printing and dyeing, food processing, etc.), achieving good treatment effects. Many users reported that after using Shandong Jianyu’s Roots blower, the wastewater treatment efficiency has increased by more than 15%, energy consumption has decreased by 20%-30%, and emission indicators have fully met national environmental protection standards, bringing considerable economic and environmental benefits to the enterprise.
