Definitions for "Surge tank"
Large vessel for capturing overflow water in competition pools equipped with a gutter recirculation system.
An overflow tank with cap, connected to an engines cooling system. Surge tank holds extra or reserve coolant to assure that the engines cooling system is completely filled at all times. A surge tank may or may not have a constant flow of coolant through it depending on design. Liquid coolant additives should be added only to those surge tanks that have a continous through-put to assure proper mixing with mainstream coolant. Top-off with a 50/50 prediluted coolant via the surge tank is acceptable.
A tank that accumulates water in response to a pressure surge and supplies water in instances of moderate negative gauge pressure, thereby preventing damage to pumping and piping equipment.
