Problems solved by technology

In the process of domestic nuclear power construction, steam turbines, condensers, foundation springs and condenser springs are usually supplied by different manufacturers. Lack of a unified and complete condenser spring and foundation spring coordinated release logic, unclear release conditions, and unclear technical requirements, resulting in a lack of technical input for on-site construction, and often resulting in inability to continue construction on site and delaying work, resulting in double construction quality and progress risk

Embodiment 1

[0055] An embodiment of the present invention provides a logic method for releasing and locking double-supported springs of a nuclear power turbogenerator set. The turbogenerator set includes a condenser, a steam turbine, and a generator. The double-supported springs include a condenser spring and a Turbogenerator foundation springs, see figure 1 , the method includes:

[0056] S1. After the installation of the condenser is completed and the water filling test is carried out, the condenser is drained to the water load designed and distributed by the condenser spring, and the condenser spring is released;

[0057] S2. Connect the condenser to the low-pressure outer cylinder of the steam turbine, fill the condenser with water to the total operating water weight of the condenser, and release the basic spring;

[0058] S3, aligning the steam turbine and the generator shaft, sequentially locking the condenser spring and the foundation spring, and emptying the water in the condense...

Embodiment 2

[0141] An embodiment of the present invention provides a system for realizing all the processes of the release and locking logic method of the double support spring of the nuclear power turbogenerator set, the turbogenerator set includes a condenser, a steam turbine and a generator, and the double support spring Includes condenser springs and turbogenerator foundation springs, see Figure 4 , the system includes:

Abstract

The invention discloses a nuclear power turbine-generator unit dual supporting spring releasing and locking logic method. The method comprises the steps that after a condenser is mounted and subject to a watering test, the condenser is subject to water draining to the water weight load designed and distributed by a condenser spring, and the condenser spring is released; the condenser and a low-pressure outer cylinder of a steam turbine are connected, the condenser is subject to watering to the total running water weight of the condenser, and a base spring is released; the steam turbine and a generator shaft are aligned, the condenser spring and the base spring are locked in sequence, and water in the condenser is emptied; after mounting and debugging of a turbo generator unit are finished,the condenser spring and the base spring are sequentially released, and starting of the turbo generator unit is prepared. The invention further discloses a nuclear power turbine-generator unit dual supporting spring releasing and locking logic system. According to the method and the system, the technical requirement and the releasing condition of dual supporting springs can be clear, and site construction quality and scheduling effective guidance is ensured.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to a logic method and system for releasing and locking a dual support spring of a nuclear power turbogenerator set. Background technique [0002] The elastic foundation technical scheme of the steam turbine generator set has the advantages of frequency modulation, preventing resonance, earthquake resistance, compensation for uneven settlement, and low civil construction cost. It is the mainstream foundation selection scheme for large half-speed nuclear power steam turbine generator sets worldwide. The foundation of the steam turbine generator set and the double spring support technology of the condenser is one of the representative schemes, which is beneficial to reduce the foundation load of the steam turbine generator set. [0003] The condenser spring release and foundation spring release run through the installation main line of the turbo-generator set. In order to ensure ...
