A first look at the table of operating parameters for Roots fans, a comparative analysis of Wagner fans and Roots fans
With the continuous development of science and technology, the use of fans in various fields is becoming more and more widespread, and with it comes the pursuit of fan efficiency. Roots fan and Wagner fan as a common type of fan, from a number of aspects can be compared, however, in the real choice to use before, need to fully understand the characteristics of the two. Next will be analyzed from the Roots fan working parameter table and Roots fan and Wagner fan comparison and other aspects.
First, the working parameters of the Roots fan table
Roots fan is a volumetric fan, mainly by the Roots gear and Roots shell two parts. Among them, the Roots gears make the gas volumetric compression between the two gears through the structure of close fit, and the gas in and out through the suction port and exhaust port, so as to achieve the purpose of gas transportation and compression. For Roots fan, we can understand more about its characteristics through its working parameter table.
1. Main parameters
The main parameters of Roots fan include inlet flow, discharge pressure, rotational speed, power, etc., of which inlet flow and discharge pressure are the main factors affecting the efficiency of Roots fan. Therefore, in the actual application, you need to choose different combinations of parameters according to the specific conditions to achieve the best results.
2. Operating characteristics
In the process of operation, Roots fan has a high compression ratio, wide flow range, good fluid sealing and other characteristics. In addition, the Roots fan also has a certain weight and volume, you need to choose for the specific use of the scene.
Second, Roots fan and Wagner fan comparison analysis
Roots fan and Wagner fan in the working principle, performance parameters, scope of application and so on there are differences. The following will be analyzed from these aspects.
1. Principle of operation
Roots fan is a kind of volumetric fan, mainly relying on the volume compression of the Roots gear to achieve gas compression and transportation, without the use of compressors and gas pipeline and other equipment. The Wagner fan is a power suction fan, which generates centrifugal force in the power wheel through the rotation of the drive shaft, thus lifting and pushing the air out.
2. Performance parameters
There are some differences in performance parameters between Roots and Wagner fans. Roots fans have a wide range of inlet flow rates and discharge pressures, while Wagner fans have lower pressure ratios and maximum flow rates than Roots fans. Therefore, in practical application, it is necessary to select the appropriate fan type according to the specific working conditions.
3. Scope of application
Roots fans are suitable for compressing, conveying and suctioning gases. And Wagner fan is suitable for exhausting some flammable, easy to spontaneous combustion or explosion risk of gas, usually used in mineral, chemical, metallurgical and other industries.
Third, the advantages of Roots fan
Roots fan as a volumetric fan, has the following advantages:
1. High volumetric efficiency
Roots fan provides global leakage equalization with relatively high volumetric efficiency. Compared with compressors, Roots fans do not need to be regulated by devices like throttle valves, and operate more efficiently.
2. Low maintenance costs
Roots fans are relatively simple in construction and have a small number of components, so their maintenance costs are relatively low.
3. Less susceptible to inertia
Since the Roots fan does not need to utilize inertia itself to perform actions such as compression, its compression capacity is not easily affected by inertia in actual production.
Fourth, the shortcomings of the Roots fan
In actual production, Roots fan also has some disadvantages:
1. large sound
Due to the operation of the Roots fan will produce a certain amount of noise, so in the application of the need to consider the impact of noise.
2. Large volume
As the gears of the Roots fan and the tank need to maintain a certain volume relationship, so its volume will be relatively large.
3. Higher price
When installing a Roots fan, you need to select the right type of equipment, so the acquisition cost of the Roots fan is higher.
V. Advantages of Wagner fans
Wagner fans, as a type of power suction fan, have the following advantages:
1. Lighter weight
The assembly structure of Wagner fans is relatively simple, so they are smaller and lighter than Roots fans.
2. Lower noise level
In the design of the Wagner fan, we can realize the effect of reducing the noise by the construction of the wind wheel, so it will not produce a large noise like the Roots fan.
3. Wide range of applications
Wagner fan is suitable for a variety of gas transportation and discharge, can be widely used in industry, construction and other fields.
Disadvantages of Wagner fans
In practice, Wagner fans also have some shortcomings:
1. Low compression ratio
Compared with the Roots fan, Wagner fan compression ratio is low, so in the actual application, you need to choose for the specific gas.
2. High maintenance costs
Wagner fans have a relatively large number of components, so there may be some cost in the maintenance process.
3. Low volumetric efficiency
As Wagner fans consume a certain amount of power during operation, they have a lower volumetric efficiency than Roots fans.
VII. Summary
The selection of Roots fans and Wagner fans needs to be tailored to different working conditions. In the selection process, you need to fully understand the characteristics and advantages and disadvantages of the two types of fans, in order to achieve the optimal selection results. Through this paper on the Roots fan and Wagner fan operating parameters table and comparative analysis, I believe the reader can have a better understanding of the two kinds of fans.
