LGMQ airbag pulse damper

Product Overview：

LGMQ-0.35/LGMQ-0.6/LGMQ-1.0/LGMQ-1.5/LGMQ-2.0/LGMQ-4.0/LGMQ-5.0/LGMQ-6.0/LGMQ-12.0、PP、PVDF、UPVCAirbag type pulse dampers, SUS304, SUS316L stainless steel airbag type pulse dampers are commonly used components to eliminate pipeline pulsation, and UPVC dampers are essential for metering pumpsflatThe pipeline pulsation caused by displacement pumps such as plunger pumps and diaphragm pumps and the elimination of water hammer phenomenon in the system are eliminated. It is isolated from the liquid in the pipeline by corrosion-resistant airbags, and UPVC dampers are used to reduce the volume of the gas chamberchangeSmooth out the pulsation of pipelines and store and release the energy of pressurized liquids.

working principle：

A damper is a device specifically designed to achieve smooth pulsation effects by storing pressurized liquids. Liquids are incompressible and utilize the compressibility of gases to achieve the purpose of storing and releasing energyYuanyi ValveThe expandable capsule of the damper is installed in the damper housing, and inert gas is filled into the capsule through a dedicated inflation valve. The gas expands and fills the entire volume of the damper housing. When the pipeline pressure is greater than the pre filled gas pressure, the liquid enters the damper, the capsule is compressed, and the gas volume decreases. When the gas pressure reaches equilibrium with the liquid pressure, the change in gas volume is the effective volume available for work.

Main functions：

1. Eliminate the harm of water hammer to the system.

2. The damper reduces the peak value of flow velocity fluctuations.

3. Reduce the impact of pressure fluctuations on pipelines, bends, and joints.

4. Absorb the pulsation of the pump, create a good working environment for it, and improve the working performance of the pump.

5. The combination of a damper and a back pressure valve can make the pressure fluctuation in the pipeline close to zero.

6. Emergency or rapid energy storage to reduce system energy consumption.

7. As an auxiliary energy source, the system is allowed to use slightly smaller pump types and smaller pipe diameters to reduce costs.

8. Dampers are used as volume compensation and pressure compensation components in the system.
