Roots blowers for boilers, as an important industrial equipment, play a crucial role in boiler systems. The following is a detailed introduction to Roots blowers used in boilers:
1、 Alias
Roots blower for boilers is also known as Roots blower, Roots vacuum pump, etc. Although these names are different, they all refer to the same device, which is a fan that operates using the Roots principle.
2、 Function
Roots blowers are mainly used in boiler systems to transport gases, especially for the transportation of combustion air. It can provide stable airflow, ensuring that the fuel inside the boiler can be fully burned, thereby improving the thermal efficiency of the boiler. In addition, Roots blowers can also be used in the exhaust system of boilers to help discharge the exhaust gases generated by combustion.
3、 Working principle
The working principle of Roots blower is based on Roots theorem, which compresses and delivers gas by two interlocked rotors rotating in opposite directions at a constant speed inside the cylinder. This working method makes Roots blowers have the advantages of simple structure, smooth operation, and low noise, and therefore have been widely used in the industrial field. Specifically, for every rotation of the three bladed impeller, two impellers perform three suction and exhaust operations. Compared to the two bladed impeller, the three bladed impeller has lower gas pulsation, vibration, and noise. There is always a small gap between the impellers on the two shafts of the fan and the hole surface inside the elliptical shell, the impeller end face, and the front and rear end covers of the fan, as well as between the fan impellers. Under the drive of the synchronous gear, wind is transported from the fan inlet along the inner wall of the shell to the exhaust side.
4、 Type and Characteristics
Belt connected Roots blower is one type of fan that has the characteristics of compact structure, low noise, low vibration, and long service life. It adopts a coupling to connect the high-pressure fan and low-pressure fan in the machining workshop, which can effectively improve ventilation efficiency and reduce energy consumption. At the same time, the linked Roots blower has a tight sealing performance, which can effectively prevent external dust and foreign objects from entering the machine, making it more stable and reliable during operation.
5、 Price and Application
The price of Roots blowers varies depending on different models and specifications. Generally speaking, the price of a small Roots blower ranges from several thousand yuan, a medium-sized Roots blower ranges from several thousand yuan to tens of thousands of yuan, and a large Roots blower may cost tens of thousands of yuan. When making a purchase, in addition to price factors, it is also necessary to consider parameters such as power, speed, exhaust volume, and the needs of actual application scenarios.
Roots blower has a wide range of applications in boiler systems, and is also widely used in the ventilation and blowing fields of industries such as papermaking, power, metallurgy, and chemical engineering. In terms of environmental governance, such as waste gas treatment in cement plants and refineries, Roots blowers also play an important role.
6、 Maintenance and troubleshooting
To ensure the normal operation and extend the service life of Roots blowers, regular maintenance and upkeep are necessary. This includes checking the wear of bearings, cleaning the dust and dirt inside the fan, checking the meshing of gears, etc. At the same time, timely handling of faults such as excessive vibration, high noise, and high temperature is also necessary, and corresponding measures need to be taken according to the specific situation to solve them.
In summary, Roots blower for boilers is one of the indispensable and important equipment in boiler systems. When selecting and using, full consideration should be given to its performance and quality, as well as the requirements of practical application scenarios, to ensure the normal operation and functioning of the boiler system.
