Pulsation damper PD608

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.

The cyclic piston movement within the circulating pump will naturally generate water hammer and hydraulic impacts. During the discharge stroke of the pump, excess liquid will enter the pulsation damper to absorb excess pressure. During the piston return, the liquid absorbed in the pulsation damper will enter the system to supplement the pressure drop caused by the piston return of the pump to finally stabilize system pressure.

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.

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).

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.

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.

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.
