Paineenalennussäiliö

Paineenalennussäiliö, also known as a pressure reducing tank or accumulator, is a type of vessel used in fluid systems to maintain a stable and consistent pressure. It is particularly useful in applications where the fluid source experiences fluctuations in pressure or flow rate, or where sudden changes in demand can cause pressure drops. The primary function of a Paineenalennussäiliö is to absorb these variations, acting as a buffer to smooth out the pressure.

The operation of a Paineenalennussäiliö typically involves a flexible diaphragm or bladder within a sealed chamber. When the system pressure rises above a set point, fluid enters the chamber, compressing the gas (usually air) on the other side of the diaphragm. This compression stores potential energy. Conversely, when system pressure drops, the compressed gas expands, pushing fluid back into the system and thus increasing the pressure. This active regulation helps prevent pressure surges and sags, ensuring that connected equipment operates within its designed parameters.

Paineenalennussäiliö are commonly found in hydraulic systems, water supply networks, and pneumatic systems. In water systems, for example, they can prevent water hammer and maintain steady pressure for appliances. In hydraulic machinery, they can ensure smooth and consistent operation of actuators and motors. The size and configuration of a Paineenalennussäiliö are determined by the specific requirements of the system, including the volume of fluid to be handled and the expected pressure range. Regular inspection and maintenance are often necessary to ensure the integrity of the diaphragm or bladder and the proper functioning of the gas charge.
