Discussion on blower selection and operating conditions
Thread Content
Hello everyone. I have been working in the field of blowers for 15 years in terms of technology and research and development. I am highly familiar with various types of blowers, including rotary vane blowers, screw blowers, suspended-type blowers, exhaust fans, and rotary blowers. I also have in-depth knowledge regarding the applications of these blowers, their structural principles, as well as the common problems that may arise. I hope to be able to communicate more with everyone through this platform. If you encounter any difficulties in the selection or use process, please reply as well; we can discuss them together and make progress together. Other fan-related questions are also welcome; let’s pool our ideas.
Let’s talk more; I’m also eager to learn*
May I ask, for a flow rate of 7,500 standard cubic feet per hour, with an inlet pressure of 2 kg of gauge pressure and an outlet pressure of 3.5 kg of gauge pressure, can a single-stage centrifugal impeller fan be used? Also, if Rohts is used, are there any domestic performance records?
Lohse is not recommended, as there are too few options in terms of manufacturers, capabilities, and performance. A single-stage centrifugal blower will work, but it belongs to the category of centrifugal blowers; if there are fluctuations in pressure, the air volume also fluctuates significantly, so it isn’t the best choice either. Screw blowers or process gas blowers could be considered. The specific choice depends on what medium you are transporting and whether there are any other requirements. It can only be determined with specific parameters; if it’s not convenient to share them, we can discuss it via private message
For such operating conditions, a liquid ring compressor is recommended as it provides stable operation
