Professional analysis: the difference between Roots fans and centrifugal fans, expanding the use of Roots fans efficiency and life expectancy

Roots fans and centrifugal fans are two common types of fans in the industrial field, and they have their own advantages and characteristics in air transportation and gas pressurization. In this paper, we will carefully analyze the Roots fan and centrifugal fan, and at the same time discuss how to expand the use of Roots fan efficiency and life.

First, the difference between Roots fan and centrifugal fan

Roots fan adopts double rotor rotating device, internal and external rotor meshing with each other, through the positive and negative meshing rotor will be discharged from the suction port, so the working principle of Roots fan is “linear movement”, will not produce eddy current, shear and other hydrodynamic phenomena. Centrifugal fans, on the other hand, produce centrifugal force through the impeller to accelerate the gas, and then pressurize the gas through the diffuser. Both have obvious differences in the working principle.

Second, the use of Roots fan efficiency and life expectancy

Improve the quality of imported design: the quality of imported design of Roots fan is directly related to its efficiency and life. Therefore, in the design stage should give full consideration to mechanical strength, dynamic balance, operational reliability and other factors, minimize local stress concentration and vibration, improve the use of efficiency and life.

Optimize the manufacturing process: In the manufacturing process, adopt advanced processing equipment and technology to ensure the machining accuracy and surface quality of parts. Adopt high-quality materials to improve mechanical strength and wear resistance and prolong service life.

Improve the lubrication system: For Roots fan, the lubrication system has a vital impact on its service life. Improve the lubrication system, use high-performance lubricants and lubrication equipment to ensure the lubrication reliability of the Roots fan in high-speed operation.

Improve the technical level: Improve the technical level of the operation and maintenance personnel, strengthen the monitoring and analysis of the operation status of the Roots fan, timely detection and resolution of problems to ensure its normal operation. At the same time to strengthen the regular maintenance and repair of the Roots fan, to extend its service life.

Further research and innovation: in the design, manufacture and operation of the Roots fan, continuous scientific research, put forward new theories, new technologies and new materials, and constantly improve the use of Roots fan efficiency and life.

Third, adjust the working parameters of Roots fan

Good load adaptation and adjustment of the Roots fan is the key to expanding its efficiency and life. By reasonably adjusting the working parameters of Roots fan, it can make it reach the best running state under different working conditions and improve the use efficiency.

Adjustment of rotor gap: Reasonable adjustment of rotor gap of Roots fan can reduce friction loss and leakage loss between inner and outer rotor and improve efficiency.

Optimize impeller design: Optimize the impeller structure of Roots fan to improve its aerodynamic performance, reduce energy loss and improve efficiency.

Optimize the flow distribution system: optimize the flow distribution system of the Roots fan to make the gas flow more uniformly inside the Roots fan, reduce the local resistance loss, and improve the use of efficiency.

Improve the sealing system of Roots fan

The sealing system of Roots fan has an important impact on its efficiency and life. Improve the sealing system of Roots fan, can effectively reduce gas leakage, improve efficiency.

Selection of high-performance sealing materials: select high-temperature resistant, wear-resistant, high-performance sealing materials with good sealing performance to improve the sealing performance of the Roots fan.

Optimize the sealing structure: optimize the design of the sealing structure of the Roots fan to reduce the friction loss between the seals and the rotor and reduce gas leakage.

Increase the seal detection device: increase the seal detection device on the Roots fan, you can find the seal leakage problem in time, take corresponding measures to extend the service life of the Roots fan.

Fifth, strengthen the operation monitoring and maintenance of Roots fan

Continuous monitoring of the operating status of the Roots fan can detect problems in time to ensure its normal operation and extend its service life.

Implementation of remote monitoring: through the remote monitoring system, real-time monitoring of the operating status of the Roots fan, and timely grasp of its operating conditions.

Strengthen regular maintenance: carry out regular maintenance and repair of Roots fan, including cleaning, lubrication, fastening and other work, to ensure its normal operation and extend its service life.

Improve the technical level of operators: strengthen the technical training of operators to improve their ability to monitor and maintain the operating status of the Roots fan.

Sixth, summarize

Through the multi-directional discussion on the improvement of the use efficiency and life of Roots fan, we can see that the use efficiency and life of Roots fan has a close relationship with the design quality, manufacturing process, lubrication system, operation and maintenance. Through continuous improvement and adjustment, as well as strengthening operation monitoring and maintenance, we can achieve the purpose of expanding the use efficiency and life of Roots fan.

VII. Outlook

As an important gas pressurization equipment, the improvement of the usage efficiency and life span of Roots fan is of great significance. In the future, we can continue to strengthen the research and development of Roots fan, put forward more improvement measures to further improve its use efficiency and life to meet the needs of industrial production.
