Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steam turbine oil cooler cooling, in particular to a novel cooling water connecting device for adjacent machines of a steam turbine oil cooler in a power plant. Background Art
[0002] Because the cylinder temperature of some power plant steam turbine units is high after shutdown, the oil cooler cannot be shut down after shutdown, which requires the circulating pump and open pump to be running. After the transformation, the oil cooler cooling water uses temporary open water, and the circulating pump and open pump of the unit can be shut down in advance, saving plant electricity; the condenser can also be cleaned in advance, shortening the maintenance period, and advancing the start-up and grid-connected time of the unit. In the event of an accident, the cooling water of adjacent units can be used as backup for each other, greatly increasing the safety factor.
[0003] The existing new type of power plant turbine oil cooler adjacent machine cooling water connecting device is not convenient for stopping the oil cooler. In the past, after the unit was shut down, due to the high cylinder temperature, the oil cooler could not be shut down after shutdown, which required the circulating pump and the open pump to be running. The cylinder temperature dropped slowly after shutdown, and it took about a week to stop the circulating pump and the open pump, which was a waste of plant electricity. The cylinder temperature dropped slowly after shutdown, and the circulating water system and the open water system could not be stopped, and the condenser could not be cleaned in time, which extended the maintenance period and delayed the start-up and grid-connection time of the unit. The open water uses the circulating water of the unit. After each shutdown, the cylinder temperature must be lower than 120℃ to stop the open water and circulating water systems, which not only leads to an increase in plant electricity consumption, but also increases the maintenance period of the unit, delaying the start-up and grid-connection time of the unit.
