Abstract

The invention relates to a flushing method of a nuclear power station steam turbine adjusting oil system. The flushing method includes the steps that a header block is provided, the header block is connected with an adjusting valve drive mechanism device, a drainage pipeline is arranged in the header block, an oil inlet and an oil outlet are formed in the two ends of the drainage pipeline separately, the oil inlet of the drainage pipeline communicates with a protective oil branch pipe in the adjusting valve drive mechanism device, and the protective oil branch pipe in the adjusting valve drivemechanism device communicates with an oil tank through a protective oil mother pipe and a power oil pipe in sequence; a flushing hose is provided, one end of the flushing hose communicates with the oil outlet of the drainage pipeline, and the end, away from the header block, of the flushing hose communicates with the oil tank through an oil return pipe; and a pump is started, a power oil isolating valve is switched off, protective oil in the oil tank sequentially passes through a system mother pipe, the protective oil mother pipe, the protective oil branch pipe, the drainage pipeline in the header block, the flushing hose and the oil return pipe to flow back to the oil tank, and therefore protective oil flushing is completed. The risk of oil leakage accidents is reduced, and the flushingefficiency is improved.

Description

technical field [0001] The invention relates to the key technical field of a mega-kilowatt nuclear power plant, in particular to a method for flushing a regulating oil system of a steam turbine in a nuclear power plant. Background technique [0002] The steam turbine unit of a nuclear power plant includes a steam turbine regulation oil system (GFR), a steam turbine regulation system (GRE) and a steam turbine protection system (GSE). The function of the steam turbine regulation oil system (GFR) is to provide the treated combustion-resistant power oil with qualified quality and operating parameters to the steam turbine regulation system (GRE) and steam turbine protection system (GSE), so as to transfer energy and have lubrication, cooling, Features such as sealing and anti-rust. Specifically, it is to provide the operating mechanism of the shut-off valve of the high-pressure cylinder of the steam turbine or the operating mechanism of the regulating valve of the high-pressure ...
