Cooling water system with high-lift TCA feed pump

The utility model discloses a cooling water system with a high-lift TCA feed pump, which is characterized in that in the process of increasing the rotating speed of a gas turbine to 3000rpm, as the lift of the TCA feed pump is higher than the high-pressure water supply operation pressure at the stag...

Zusammenfassung:	The utility model discloses a cooling water system with a high-lift TCA feed pump, which is characterized in that in the process of increasing the rotating speed of a gas turbine to 3000rpm, as the lift of the TCA feed pump is higher than the high-pressure water supply operation pressure at the stage from gas starting to no-load full rotating speed, the cooling water of a TCA cooler is low-temperature condensed water; when the no-load rotating speed of the gas turbine is increased to 3000rpm, a constant-speed signal of the gas turbine triggers the TCA cooling water pump to stop running, the first water outlet end is cut off, cooling water flowing through the TCA cooler is automatically switched into a high-pressure water feeding pump for low-pressure water feeding, and the following gas turbine is started according to the original starting process of the power plant. By means of system switching, inlet media of the high-pressure water feeding pump and the TCA water feeding pump of the unit are not changed, th
