Embodiment Construction

[0021] like figure 1 As shown, an installation and adjustment process of the nuclear main pump before drilling and reaming uses the seam positioning method to complete the installation and adjustment of the pump cover 3 and the sealing chamber 2, places the sealing chamber 2 at the rotation center of the machine tool, and places the lower motor support 6 Place it on the pump cover 3, adjust the center of the lower motor support 6, when the center of the lower motor support 6 coincides with the center of the sealing chamber 2, use the bolt 4 and the nut 5 to tighten the sealing chamber 2, the pump cover 3, and the lower motor at the same time Bearing 6, said method comprises the following steps:

[0022] 1) Hang the pump casing 1 on the workbench of the machine tool, and install the sealing chamber 2 in the pump casing 1;

[0023] 2) Adsorb the dial indicator on the tool bar of the machine tool, turn the machine tool table, check the radial runout of the inner diameter surface...

Abstract

The invention relates to a process for installation and adjustment of a nuclear main pump before drilling and reaming. The installation and adjustment of the pump cover (3) and the sealing chamber (2) are completed by using the seam positioning method, and the sealing chamber (2) is placed at the rotation center of the machine tool , place the lower motor support (6) on the pump cover, and adjust the center of the lower motor support (6). When the center of the lower motor support (6) coincides with the center of the sealed chamber (2). Use bolts (4) and nuts (5) to tighten the sealing chamber (2), pump cover (3) and lower motor support (6) at the same time. The invention guarantees the coaxiality of the three parts of the sealing chamber (2), the pump cover (3) and the lower motor support (6) before co-drilling and reaming, and uses pin positioning after co-drilling and reaming to prevent the main pump from Misalignment and displacement occur between the three parts during operation, which prevents the main pump from vibrating, and has good practical effect, achieving the expected effect of nuclear power main pump installation.

Description

Technical field: [0001] The invention relates to an installation and adjustment process of a nuclear main pump before drilling and reaming. Background technique: [0002] The seal chamber, pump cover and lower motor support are the primary components of the nuclear main pump. The seal chamber and the pump cover form the cavity of the main pump. The main pump motor runs on the lower motor support. When the main pump is in normal operation, the speed It is 1486 rpm. The water temperature in the sealing chamber is 299 degrees Celsius, and the main pump is prone to vibration in the state of high temperature, high speed and high pressure. Therefore, an installation and adjustment process is required to perform the same processing among the three, and then use cylindrical pin positioning to control the sealing chamber, pump cover, and lower motor support. The coaxiality after the seat is installed. At present, there is no precedent for nuclear main pump manufacturing in China, a...
