Embodiment Construction

[0021] Such as 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 surf...

Abstract

The invention relates to an installing and adjusting process before drilling and reaming for a nuclear main pump. Installing and adjusting of a pump cover (3) and a sealing chamber (2) are completed by adopting a seam allowance positioning method, the sealing chamber (2) is placed in a rotating center of a machine tool, a lower motor support (6) is placed on the pump cover, the center of the lowermotor support (6) is adjusted, and when the center of the lower motor support (6) coincides with the center of the sealing chamber (2), the sealing chamber (2), the pump cover (3) and the lower motorsupport (6) are simultaneously and tightly sealed by bolts (4) and nuts (5). According to the installing and adjusting process before drilling and reaming for the nuclear main pump, the coaxiality ofthe sealing chamber (2), the pump cover (3) and the lower motor support (6) before simultaneous drilling and reaming is guaranteed, after simultaneous drilling and reaming, pin positioning is used for preventing dislocation and displacement of the three parts in the operation process of a main pump, vibration of the main pump is prevented, the practical effect is good, and the expected effect ofnuclear power main pump installation is achieved.

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...
