LGMZ type diaphragm pulse damper
Product Overview
Pulse dampers, also known as pulsation dampers or pulsation buffers, are commonly used components for eliminating pipeline pulsation and are essential accessories for metering pumps. Pulsation dampers can smooth out pipeline pulsations and water hammer phenomena caused by volumetric pumps such as metering pumps and diaphragm pumps. It is isolated from the liquid in the pipeline by a corrosion-resistant diaphragm, and the pipeline pulsation is smoothed by changes in the volume of the gas chamber. Shell material: PVC, PP, PVDF, SUS304, SUS316L, etc. Diaphragm Material: PTFE Composite, FPM (Fluororubber), EPDM (Ethylene Propylene Diene Monomer), NBR (Nitrile Nitrile)
Functional Features
Reduce the harm of water hammer to the system.
Reduce the peak value of flow velocity fluctuations.
Protect pipelines, valves, and joints from the impact of pressure fluctuations.
Create a favorable working environment for metering pumps and improve their performance.
Allow the system to use smaller pipe diameters to reduce costs.
When used in conjunction with back pressure valves, it can make the pressure fluctuations in the pipeline close to zero.
Reduce the energy consumption of the system.
Volume selection of diaphragm dampers
The hourly flow rate of the pump+60: the number of strokes per minute of the pump x15=the actual minimum volume required by the damper. The minimum volume of the damper required to reduce 90% of the pulse can be obtained by multiplying the metering capacity (ml) of the metering pump (or diaphragm pump) per stroke by 15. Note: (This calculation method is applicable to single head pulse type pump bodies, multi head pumps are discussed separately.)
working principle
According to Boyle's law P, V,=P, V, the volume of a gas is inversely proportional to its pressure, and pipeline pulsation is smoothed by changing the volume of the gas. For systems with sinusoidal flow velocity, when the peak occurs, the volume of the air chamber decreases and the pulse damper absorbs excess liquid flow; When the valley is reached: the volume of the air chamber increases, releasing the stored liquid and achieving a smooth pulsation effect.
