Embodiment Construction

[0015] In order to make the present invention more comprehensible, a preferred embodiment is described in detail below with accompanying drawings.

[0016] figure 1 and figure 2 It is respectively a front view and a side view schematic diagram of a 1000MW nuclear power unit condenser spring support provided by the present invention. The described a 1000MW nuclear power unit condenser spring support includes a lower casing 1 and a The upper casing 2 and the spring assembly 3 are installed between the lower casing 1 and the upper casing 2 .

[0017] The spring group 3 is composed of six large springs and N (0≤N≤6) small springs, the diameter D of the large springs ranges from 28mm≤D≤84mm, and the diameter d of the small springs ranges from 16mm≤d≤48mm. Six large springs are arranged in two rows and three columns. The number of small springs can be selected according to the load requirements of the condenser. The number ranges from 0 to 6. The small springs are arranged inside...

Abstract

The invention provides a spring support of a condenser of a 1,000MW nuclear power unit. The spring support is characterized by comprising a lower shell and an upper shell arranged above the lower shell, wherein a spring group is arranged between the lower shell and the upper shell and comprises six large springs which are arranged into two rows and three columns; and small springs are arranged inside the large springs from the middle to the two sides. By the spring support, the shortcomings in the prior art are overcome; since the small springs are arranged inside the large springs and limiting rings are arranged on the upper shell and the lower shell, the spring support meets the supporting requirement of the condenser of the1,000MW nuclear power unit and has high stability.

Description

technical field [0001] The invention relates to a spring support for a condenser of a 1000MW nuclear power unit, belonging to the technical field of large nuclear power condenser units. Background technique [0002] The 1000MW nuclear power unit has high requirements on the overall stability and seismic resistance of the unit, so the bottom support of the condenser is supported by springs. At the same time, the overall weight of the condenser of the 1000MW nuclear power unit is relatively large, and the requirements for the overall strength, stiffness and life of the spring support are relatively high. The traditional spring support has disadvantages such as poor stability and small load capacity, which cannot meet the support of large condensers. Require. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a spring support that meets the support requirements of the condenser of a 1000MW nuclear power unit and has good stab...
