Methods to eliminate pulsation in piston pumps?
Thread Content
What methods can be used in piston pumps to eliminate pulses from a technical perspective? Is it possible to completely eliminate pulses? If a flow meter is installed at the pump outlet, will the flow rate fluctuate frequently? Both multi-plunger and pulse dampers were tried, but they didn’t work、、
It’s a multi-plunger design, and the number of plungers is odd: three or five. There’s also a buffer tank at the outlet; if it doesn’t work, it might be because the size chosen was too small
Plunger pumps are mostly used with high-pressure liquid media, and the higher the pressure, the greater the vibration; there isn’t much that can be done regarding the pulses generated by the pump itself. If it is for signal acquisition to measure flow rate, it is best to find an alternative approach.
Well, we’re facing such a problem; now we plan to use a high-speed pump as a replacement, and the purchaser wants to use a plunger pump
I don’t know the specific details; there are many methods of measurement.
Vibration at the outlet of a piston pump is also a characteristic of such pumps. To date, no effective measures have been found to eliminate this issue; the best approach currently available is to use an outlet buffer tank to reduce vibration.
A suitable buffer tank can achieve an ideal pressure stabilization effect, with no vibration felt at all
Add a buffer tank or connect the outlet with a high-pressure hose
By adding buffer tanks and operating the valves upstream and downstream of the flow meter, the flow rate can be essentially stabilized.
