Why is there a loud noise from the gas pipeline?
Thread Content
Currently, 2 Roots blowers are in operation (one supplies 40,000 cubic meters of air per hour). The outlet of the blowers is DN700; the pipeline after 3 meters from the outlet has a diameter of DN800. The two blowers are connected in parallel to a DN1600 pipeline at a high elevation. Due to limited space at the time, there is a 6-meter height difference between the DN800 pipeline and the DN1600 pipeline, and there are 3 90-degree bends. The current operating frequency of the blowers is 90, with a pressure of 17 KPA. The noise in the pipes is very loud all the time. Why is that? Sometimes the noise comes in bursts. Are there any ways to improve this situation? I’m asking for help from experts!
There is no difference in level, and it’s hard to tell from the pictures of the elbows. The 700 caliber model has high output power but also generates a lot of noise. . Rotary vane blowers are noisy. Exports (this area is equipped with shock absorption); flexible connections (noise reduction) are designed at the corners
You have two fans, changing 700 to 800, connected in parallel to a 1600 pipeline. . I still need to send pictures, right?
