What is the purpose of a surge tank?
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.
What is the energy equation for a surge tank?
The energy equation for unsteady flow, neglecting fluid friction and velocity head in the surge tank and loss at pipe and surge-tank entrances, can be written as where y is the water level in the surge tank measured from the static level (positive upward), L, f, and D are characteristics of the pipe between the tank and the reservoir,
When does the maximum surge height occur in a tank?
The maximum surge height occurs at time , i.e. A large value of i.e. a large surge tank area, means a small but a longer periodic time . Changes in reservoir level and the inertia of the water column in the surge tank have been neglected.
Can a surge tank be used on a high head line?
A surge tank is not economical on an extremely high-head line because of the great height of tank required. In such cases, a decrease in the delivery of water to the turbine is best accomplished by use of defection nozzles or bypasses, which do not require an immediate decrease in flow through the pipe itself.
What do you need to know about a surge tank?
The surge tank usually consists of a single or double compartment vessel and a level measuring system with sight glasses or magnetic levels. To prevent overpressure and overfilling, the surge tank is fitted with a pressure-relief valve and a high- and low level alarm system.
How does the surge tank in a fuel cell work?
By using the flow in your fuel system the surge tank will be constantly filled with fuel. The lift-fuel pump will provide fuel from your fuel tank or fuel cell while the excess fuel returned from the Fuel Pressure Regulator is circulated back into the surge tank.
Where does the surge tank hose come from?
The surge tank hose runs from the top right hand corner of the radiator to the surge tank, and can come in contact with the fuel injector or other engine parts as it tends not to be attached to anything. Because of this fact, the surge tank hose can come into contact with warm or even hot engine parts.
