Connecting the output hose of the peristaltic pump or diaphragm pump to the input connector of the damper, and connecting an output hose to the container at the output connector, constitutes a typical application mode. If pulse data is required, a pressure sensor can be connected in series between the output end of the peristaltic pump and the input end of the damper, and a pressure sensor can also be connected in series between the output end of the damper and the output hose. Connect the signal ends of the two pressure sensors to the oscilloscope, turn on the power of the peristaltic pump, and when the water flows through the damper, the buffer wing first buffers and diverts the fluid, and the water flows into the fluid cavity in two ways, left and right. When the two fluids contact the L rectifying wing and the R rectifying wing respectively, the two fluids are gathered to the inner side of the buffer wing under the action of the L and R rectifying wings. At this time, due to the action of the fluid pressure, the fluid pulse is fully released into the buffer air cavity through the pulse buffer membrane and discharged into the atmosphere through the breathing hole set in the upper cover. The turbulence of the water flow is rectified by the L rectifying wing and the R rectifying wing, and at the same time, the ideal liquid that is approximately horizontal flow is smoothly output under the continuous input fluid force, so as to achieve the effect of rectifying and suppressing pulses. It effectively solves the shortcomings of pulsating fluid, especially the unstable flow of peristaltic pump. It is suitable for laboratories, chemicals, medicine, food and other industries because of its simple principle and structure, stable and easy maintenance, and strong applicability.
In typical applications, the pulse suppression rate of the D1606 series can reach more than 95%. In situations where high requirements for water flow stability are required, the method of connecting two dampers in series can be used to achieve a higher requirement for pulse rectification. The suppression rate can reach more than 99%, close to 100%.
