Surge tank


From Wikipedia, the free encyclopedia

A surge tank (or surge drum) is a standpipe or storage reservoir at the downstream end of a closed aqueduct or feeder pipe to absorb sudden rises of pressure, as well as to quickly provide extra water during a brief drop in pressure.
In mining technology, ore pulp pumps use a relatively small surge tank to maintain a steady loading on the pump.
For hydroelectric power uses, a surge tank is an additional storage space or reservoir fitted between the main storage reservoir and the power house (as close to the power house as possible). Surge tanks are usually provided in high or medium-head plants when there is a considerable distance between the water source and the power unit, necessitating a long penstock. The main functions of the surge tank are: 1. When the load decreases, the water moves backwards and gets stored in it. 2. When the load increases, additional supply of water will be provided by surge tank.
In short, the surge tank mitigates pressure variations due to rapid changes in velocity of water.

surge tank is used for storage of water or any solution. It is the main vessel from where the solution is pumped to main tower..

Hi,

It is normally located between, let say, two process units in order to reduce the upsets due to flowrate variations between them. It dampens the changes in the specified flowrate while keeps the liquid level in the tank between two predetermined limits.
