Virtaussäiliöt

Virtaussäiliöt, also known as flow tanks or surge tanks, are hydraulic devices designed to manage rapid changes in fluid flow within a system. Their primary function is to absorb or supply fluid volume to counteract pressure fluctuations and water hammer effects. These devices are particularly crucial in systems where flow rates can change abruptly, such as hydroelectric power plants, pumping stations, and water distribution networks.

The design of a virtaussäiliö typically involves a chamber connected to the main pipeline. When flow increases suddenly, the excess fluid enters the chamber, increasing the liquid level and thus providing a buffer. Conversely, if the flow rate decreases sharply, the fluid stored in the virtaussäiliö is released back into the pipeline, helping to maintain a stable pressure and prevent negative pressure surges. This dynamic response mitigates the damaging forces associated with water hammer, which can otherwise cause significant stress on pipes, valves, and other equipment.

The effectiveness of a virtaussäiliö depends on its size, shape, and placement within the hydraulic system. Proper sizing is essential to ensure it can accommodate the expected volume changes without overflowing or becoming completely empty. Their application helps to improve the operational reliability and longevity of fluid transport systems by smoothing out the inherent variability in flow dynamics. Virtaussäiliöt are an integral part of ensuring the stable and safe operation of many fluid engineering projects.
