Description

Vessel Support System

technical field

The present invention relates to a steam-water separation reheater in a conventional island of nuclear power, in particular to a vessel support system.

Background technique

Soda water separation reheater, namely Moisture Separator and Reheater, referred to as MSR. MSRs and turbogenerators are the main components in conventional islands of nuclear power plants. The MSR removes most of the water from the steam exhausted from the high pressure cylinder of the turbogenerator and also increases the temperature of the steam before it enters the low pressure cylinder of the turbogenerator.

The MSR usually includes the casing. Mounting systems for MSRs typically include several mounts. Each standoff needs to support the housing to provide support and retention for the MSR. There are usually several pipes between the MSR and the turbo-generator, and the pipes can transmit the heat transfer medium between the MSR and the turbo-generator. Since the MSR will produce temperature changes during the working process, the temperature changes will cause thermal expansion of the MSR's shell. Thermal expansion can cause changes in the dimensions of the housing and can also cause thrust between the pipe and the housing, which can cause vibration and displacement of the housing. In order to adapt to the vibration and displacement of the housing, the support system usually needs to be set to a movable state.

Not only does each support bear the weight of the MSR, but it also needs to accommodate the displacement that occurs when the enclosure thermally expands, as well as the thrust between the enclosure and the pipe.

In the prior art, in order to accommodate the displacement generated by the thermal expansion of the casing, the support system usually includes a fixed support and a sliding support. The sliding support is provided with a waist-shaped hole, and the connecting piece can pass through the waist-shaped hole, so that the sliding support can slide along the length direction of the waist-shaped hole, so as to adapt to the thermal expansion of the shell.

In the prior art, in order to adapt to the relative displacement between the casing and the pipe, an expansion joint is also provided between the casing and the pipe, and the expansion joint can be telescopically deformed, thereby eliminating the thermal expansion difference between the pipe and the casing, and adapting to the difference between the casing and the pipe. relative displacement between.

The mating relationship between the two in the sliding process is surface contact, so that the flatness between the sliding bearing and the installation foundation is required to be high, so the manufacturing and assembly of the bearing system are more difficult; The sliding fit is easily disturbed by external factors, resulting in poor sliding, so that the thermal expansion of the casing cannot be fully released, and the casing and the support are at risk of deformation and damage.
