Pulsation Dampener Working Principle

As a backpressure impact damper
If there is a sudden power off for the pump while transporting the liquid to a high spot, the liquid in the pipeline will return and accelerate in the pipeline. Water hammer with great destructive power will be formed at the check valve that is installed at the outlet of the pump. If the pipeline is long, the water hammer may cause the pipeline to bust. The longer the pipeline, the longer the fluid accelerate, the bigger the impact.

Taloar pulsation damper can effectively absorb such water hammer. Besides, Taloar pulsation damper is designed with a unique check valve structure with “fast-in and slow-out” feature, can effectively absorb water hammer instantly. It takes relatively long time to release excess pressure, ensuring stable pressure in the pipeline system.

As a supply-end shock absorber
It is important to note that in the case of circulating pumps, water hammer and hydraulic shocks are an inherent consequence of the piston’s cyclic movement. During the discharge stroke of the pump, any excess fluid enters the water hammer eliminator, where it absorbs the excess pressure. As the piston returns, the liquid absorbed in the water hammer eliminator re-enters the system, replenishing the pressure drop caused by the pump piston’s return and thereby stabilizing the system pressure.

As a suction-end shock absorber
If there is no sufficient water supply, the pump efficiency will highly affected. Pitting is related to the fluid velocity, acceleration, and friction. If the supply at pump suction is insufficient, vacuum will form at the supply under the suction of the pump, resulting in “pitting”.

Install Taloar pulsation damper at the pump suction. This will act a buffer pool: If the suction of the pump is insufficient, the liquid stored in the pulsation damper will be supplied to the system to ensure the pump suction is sufficient. If the system supply is too large, excess liquid will enter the pulsation damper to ensure pump suction is stable, thus greatly improving the service life of the pump.

As a hydraulic impact damper
All liquid flow has kinetic energy. When the fluid suddenly stopped, its kinetic energy will convert into pressure and this very dangerous. Such “water hammer phenomenon” usually occurs in pipeline systems with quick-closing valves. The destructive power generated by “water hammer phenomenon” is strong enough to damage devices like pipelines, valves, and pumps.

There are many reasons for “water hammer phenomenon”, such as quick-closing valves, back pressure impact, pump start-up or shutdown and sudden loss of power in the system (such as power failure).

Energy storage
If the system experiences sudden power off or pump failure, Taloar pulsation damper can maintain pressure within the system for a short time to ensure that other moving and working parts are still lubricated and cooled, so as to protect the equipment.

Thermal expansion absorption
When liquid flows in a closed system, the liquid temperature will rise due to friction or other reasons, the resulting liquid expansion will cause the system pressure to increase. If the pressure exceeds safety pressure limit of the system, it will cause the pipeline to bust, valve failure, damage to precision instruments on the pipelines. Besides, in case of system leakage, the liquid in the pipelines may cause permanent damage to personnel and the surrounding environment. Use Taloar pulsation damper will absorb the excess pressure caused by the thermal expansion of the liquid to ensure the safe operation of the system.

Isolation Device
If the pressure parameters of the system are extremely important for safety operation of the system, the instruments measuring such parameters are not allowed to contact with the fluid in the system, Now Taloar pulsation damper can help solve this problem. In this case, the diaphragm of Taloar pulsation damper performs an isolation function.

Please select the most appropriate model of pulsation damper for your system, taking into account the pressure and flow rate.

The installation location should be in close proximity to the source of potential water hammer, such as near valves or pumps.

It is essential to conduct regular inspections and maintenance to guarantee the optimal sealing and performance of the pulsation damper.
