AI Technical Summary

Technical Problem

In the refrigeration units of nuclear power plants, due to the complex arrangement of refrigerant pipelines and lubricating oil pipelines, the common centering tools composed of dial meter and dial meter seats are difficult to or cannot be installed, and when the circumference of the coupling is large, the probe of the dial meter cannot contact the measurement surface, resulting in the inability to rotate the wheels on both sides of the coupling 360°.

Method used

A coupling centering device is designed, including a screw, a meter frame, a fixing disk, a plurality of first fasteners and a plurality of second fasteners. The fixing disc is fixed by the bolt hole on the wheel on the motor side. The dial meter on the meter frame is adjustable. Through the fitting of the first wire hole and the second fastener, the probe of the dial meter can contact the measuring surface.

Benefits of technology

This device can achieve precise adjustment of coupling centering in the refrigeration unit of the nuclear power plant, solve the problem that the dial meter probe cannot contact the measurement surface, and avoid the risk of interference with the pipeline, achieving 360° discrimination of the opposite wheels on both sides of the coupling.

Abstract

The utility model discloses a centering device for a coupler. The centering device comprises a screw rod, a gauge stand, a fixed disc, a plurality of first fasteners and a plurality of second fasteners, the fixing disc is fixed to the motor side coupling, so that the coupling centering device is integrally located between the motor side coupling and the compressor side coupling of the coupling, and the space on the periphery of the coupling is not occupied. Moreover, when the fixed disc is fixed on the pair wheel on the motor side, the surrounding pipeline arrangement just has an avoiding space, and the dial indicator installed on the indicator frame just does not interfere with the surrounding pipeline when rotating along with the pair wheel. A second through hole used for installing the dial indicator and a first screw hole communicated with the second through hole are formed in the indicator frame, the penetrating direction of the first screw hole is perpendicular to the penetrating direction of the second through hole, and the second fastener penetrates through the first screw hole and can move in the penetrating direction of the first screw hole, so that the dial indicator is fixed to a proper position. The position of the dial indicator is adjustable, so that the measuring head of the dial indicator can be in contact with the measuring surface.
