How to select the inlet and outlet pulsation dampers for 5-cylinder and 3-cylinder piston pumps? In addition to considering the indications of the inlet and outlet flow meters, the vibration of the outlet pipeline must also be taken into account. Flow rate, pressure. What else needs to be considered?
High-pressure vibrations are difficult to handle; the only solution is to use a tank with a relatively larger capacity as a buffer, which can reduce vibrations to some extent. The effect at low pressure is better; for reference only.
In fact, you can contact the specific manufacturers; provide them with the relevant parameters as required by them, and they will help you choose the appropriate model.
Users prefer a lower pulsation elimination rate value. To prevent the flow meter from experiencing fluctuations in flow rate that are too large or too small, it would be best to keep those fluctuations within the range of +/-0.75. It is necessary to determine what type of pulsation damper should be used to achieve this.
I’m not the manufacturer; I just offer some ideas. Personally, it’s a good idea to install more of them on the pipes, in order to mitigate the effects of pulsations in batches
