Embodiment Construction

[0018] Such as figure 1 As shown, a multi-component combined hoisting method of the nuclear main pump, the sealing chamber 1 and the pump shaft 2 are precisely positioned and integrated into a whole through the combined positioning device, and the lifting and transfer of multiple components are completed through the lifting plate 3. The above method includes The following steps:

[0019] 1) Drop the pump shaft 2 on the bottom of the sealed chamber 1;

[0020] 2) The sealing chamber 1 and the lifting plate 3 are connected and fixed by the first hexagonal screw 4;

[0021] 3) After the shaft bracket 5 is set on the pump shaft 2, it is fixedly connected with the lifting plate 3 with the second hexagonal screw 6;

[0022] 4) The stretching bow 9 is fixedly connected with the shaft bracket 5 by the third hexagon screw 10;

[0023] 5) The screw rod 8 is screwed into the lower pump shaft 2 through the stretching bow 9 and fixedly connected with the nut 7;

[0024] 6) At this time...

Abstract

The invention relates to a nuclear main pump multi-component combined hoisting method which is characterized in that a hoisting disc (3) is mounted on a sealing chamber (1), a shaft bracket (5) is mounted on a pump shaft (2), and the shaft bracket (5) and the hoisting disc (3) are connected, so that the sealing chamber (1) and the pump shaft (2) are integrated. The shaft bracket (5) completes radial positioning of the sealing chamber (1) and the pump shaft (2). The whole movement and transfer of the sealing chamber and the pump shaft is completed by crane lifting. According to the nuclear main pump multi-component combined hoisting method provided by the invention, the coaxiality of the pump shaft and the sealing chamber in the lifting process is guaranteed, so that accidents caused by displacement of the pump shaft in the lifting process are avoided; and meanwhile, multiple parts are lifted together, so that the working efficiency is improved, accuracy and convenience of part positioning are guaranteed, operation is easy and convenient, the practical effect is good, and the expected effect of nuclear power main pump installation is achieved.

Description

Technical field: [0001] The invention relates to a multi-component combination hoisting method of a nuclear main pump. Background technique: [0002] The seal chamber and the pump shaft are the primary nuclear components of the nuclear main pump, and the sealing chamber is the primary nuclear pressure-bearing component. It is required that there should be no scratches or scratches during assembly and lifting. During the installation of the nuclear main pump The two parts need to fall into the pump casing at the same time. During this process, the pump shaft and the sealing chamber cannot be displaced relative to each other, thereby ensuring the coaxiality of the pump shaft and the sealing chamber, and completing high-precision assembly and lifting. At present, there is no precedent for nuclear main pump manufacturing in China, and there is no experience to learn from. We need to constantly explore and research to invent a set of reasonable multi-component combination hoistin...
