Solving the problem of excessive vibration in pneumatic diaphragm pumps
Thread Content
Acidic and alkaline wastewater is pumped to the wastewater treatment center using pneumatic diaphragm pumps. However, the outlet pipes of these pumps experience significant vibration. How can this problem be solved? Can another type of pump be used as a replacement, such as an electric diaphragm pump?
Why be suppressed! Is the pipeline layout reasonable? Add pipe supports or tighten
The pipeline layout is reasonable and pipe hangers are in place, but the pipeline vibration remains quite high
Small spring supports can be considered to dampen vibrations. Actually, I quite like the thudding sound produced by pneumatic diaphragm pumps and pipelines; it’s like heavy metal rock music. :lol
Mm-hmm, but over time the pipes become distorted due to vibration, which makes leaks more likely
Check whether the damper pressure is 60-80% of the outlet pressure
It can be discussed with the process team; if there is no need for precise measurement, a chemical centrifugal pump can be used instead
Diaphragm-type pulse dampers are installed at the outlet to eliminate the operating pulses of the metering pump

1. Fix the pump in place. 2. Install a section of flexible metal hose at the outlet to absorb vibrations
Everyone has talked about the methods for use on pipelines, but are there any good suggestions for alternative types of pumps?
