Pulse damper working performance

RFQ about the pulsation dampener for peristaltic pump.

Q: What is the applicable flow range of the damper?
A: D1606 series dampers are selected based on the inner diameter of the pump tube and the liquid pressure.

Q: Is the D1606 series damper effective? Can it completely eliminate pulses?
A: The D1606 series fluid pulse damper has a pulse suppression rate of more than 95%, which can meet the needs of most users and the requirements for liquid flow patterns.
In high-voltage situations, two dampers can be connected in series, and the pulse suppression rate is close to 100%.

Q: Will adding a damper change the pressure and flow of the liquid?
A: The flow rate per unit time is constant, and the pressure at the output end of the damper is the average value at the input end.

Q: Does the D1606 series damper have a lower flow limit? Can it work under low flow conditions?
A: There is no lower flow limit, but when used under low flow conditions, the output end of the damper needs to be changed in diameter, that is, the output end pipe diameter is smaller than the input end;

Q: Will the use of a damper affect the control accuracy of the pump?
A: The D1606 series dampers use three-wing rectification technology (buffer wing + L rectification wing + R rectification wing), which does not affect control accuracy.

Q: After installation, it is found that it has no effect and the pulse still exists. What is the reason?
A: This situation is basically caused by improper installation or incorrect pipe connection! You can take a complete video of the pipeline and send it to
SCPOGO technicians, Pangu after-sales and technical staff will help you analyze the reasons based on the video and provide solutions in a timely manner.

Q: How to solve the problem of liquid discontinuity when the pump speed is slow?
A: The pipe diameter at the output end of the damper can be reduced to increase the liquid pressure in the buffer chamber to alleviate intermittent interruption.
If the discontinuity problem still exists at extremely low conditions, it is necessary to consider using two dampers in series to solve it.

Q: To what extent can the instantaneous liquid pulse be theoretically reduced?
A: The damper releases the instantaneous pulse through the elastic buffer film through the buffer wing and two rectifying wings. The suppression rate of the instantaneous peak pulse is
More than 95%, if two are connected in series, the pulse suppression can be close to 100%.

Q: What are the advantages of the three-wing rectification technology of the D1606 series damper?
A: Easy to clean, adaptable to low flow scenarios, with high pulse suppression rate, and can pass liquid containing particles without affecting the flow rate.

Q: Can the D1606 series damper pass liquid with particles?
A: Yes, the D1606 damper uses a unique three-wing structure technology to suppress pulses and can pass particulate matter. The specific size of the passing particles can be determined according to the model of the damper.

Q: How long is the life of the damper? Do I need to replace any wearing parts?
A: The service life depends on the working conditions, such as: liquid pressure, temperature, pH, pulse frequency, etc. D1606 series dampers
The structure is exquisite, among which only the pulse buffer film is a vulnerable part. It has a service life of more than two years under normal use (normal temperature, normal pressure, neutral liquid). It is easy to replace the buffer film after it is damaged.

Q: Can the D1606 series damper be used on pulsed gas?
A: D1606 series dampers can be used on pulsating gases and can also suppress gas pulses.

Q: What method can be used to eliminate the fluid accumulation in the damper cavity after shutdown?
A: When installing, the input end is downward, the output end is upward, and it is tilted at a 45-degree angle. When it is stopped, run the peristaltic pump in reverse for a few seconds, or set a drain valve between the pump output end and the damper input end. .

Q: Does the D1606 series damper need to be disassembled for cleaning?
A: Cleaning is very convenient, no need to disassemble it! Just start the pump and pass clean water or hydrogen peroxide to complete the cleaning.
