Yamada® AD Os amortecedores de pulsação da série reduzem muito as flutuações de pressão no fluxo de fluido quando montados o mais próximo possível da bomba. Os amortecedores Yamada® AD incorporam um motor a ar de alívio automático completamente automático se ocorrer um aumento ou diminuição na carga da descarga.

Para fluidos com alto teor de sólidos, os amortecedores Yamada®AD incorporam um projeto de fluxo contínuo que mantém os sólidos em suspensão, mantendo a eficácia do amortecedor. Os amortecedores Yamada® AD não restringem o fluxo do fluido nem aumentam a pressão do fluido, mas compensam os vazios e as flutuações de pressão criadas por uma bomba de diafragma pneumático de duplo diafragma (AODD).

PRINCIPLES OF OPERATION

Compressed air is introduced to the top section of the pulsation dampener at the same operating pressure of the pump. When the air opereted double diaphragm pump produces a pulse, fluid will enter the in-line dampener. As fluid enters the dampener, the trapped air behind the dampener is compressed. The fluid remains in the dampener until the system pressure returns to normal or when the pump begins another cycle. The fluid is then pushed back into the system piping as the trapped gas expands. The dampener does not restrict fluid flow, nor increase its pressure, but fills the voids and pressure flunctuations created by an air operated double diaphragm pump.

APPLICATIONS

Metering / Injection / Dosing:  smoothing out discharge flow, increasing accuracy

Filter Press / Inline Filters:  Increase filter efficiency by providing smooth flow.

Spraying:  Smooth and consistent spray pattern is easilty accomplished.

Filing:  Eliminates inconsistent filling and splashing.

Transfer:  Eliminates harmful water hammer, which damages piping and valves.

 

INSTALLATION

Mount the pulsation dampener as close to the pump as possible. This will allow the pulsation dampener to see as much operation pressure as possible, which will increase pulsation dampener efficiency and effectiveness.

If the pulsation dampener is to be used in a low head application, you may need to add a control valve after the pulsation dampener to restrict flow and increase resistance.

Mount the pulsation dampener in a horizontal position. Vertical positioning is acceptable if you are pumping a clear fluid.
