The function of pulse damper

       A pulse damper is a special accumulator used to eliminate pressure or flow pulsations in a pipeline. It can stabilize fluid pressure and flow, eliminate pipeline vibration, protect downstream instruments and equipment, and increase pump volumetric efficiency.

Pulse dampers are widely used in industries such as chemical, water treatment, food and beverage, power, papermaking, textile, and fluid machinery. They are primarily used to eliminate pipeline vibration, reduce pressure pulsations, minimize flow fluctuations, and protect downstream instruments and equipment. Installed at the front end of a pump, they increase the pump's volumetric efficiency and improve output power.

Installation method

• The diaphragm pulse damper should be installed as vertically as possible, close to the pump outlet. If the piping between the pump outlet and the pulse damper is too long, vibration may still occur in the piping, weakening the vibration damping effect.
  
• To configure a simple pulse damper, you need to understand basic system parameters, such as system pressure and motor speed. A diaphragm pulse damper can reduce system vibration to less than 200 mbar.
  
• If a pulse damper without a diaphragm is used, the gas inside will be quickly absorbed by the liquid, thus failing to protect the system.
  
• Using a pulse damper may also increase system resistance.
  

       In addition, diaphragm pulse dampers can smooth pipeline pulsations caused by positive displacement pumps such as plunger pumps and diaphragm pumps, and eliminate water hammer in the system. They use a corrosion-resistant diaphragm to isolate the gas from the liquid in the pipeline, smoothing pipeline pulsations through changes in the gas chamber volume, and storing and releasing the energy of the pressurized liquid.
      Their main functions include:
      1. Eliminating the harmful effects of water hammer on the system.
      2. Reducing the peak value of flow velocity fluctuations, ensuring accurate readings on the pump outlet pressure gauge.
      3. Reducing the impact of pressure fluctuations on pipelines, elbows, and joints.
      4. Absorbing pump pulsations, creating a good working environment for the pump and improving its performance, extending its service life.
      5. Allowing the system to use smaller pipe diameters, reducing costs.
      6. When used in conjunction with back pressure valves, it can reduce pipeline pressure fluctuations to near zero.
      7. Emergency or rapid energy storage, reducing system energy consumption and saving costs.
