Abstract
The present invention relates to an apparatus for testing the performance of a damper for damping an electric control panel of a power plant, and more particularly, to an apparatus for testing the performance of a damper, And more particularly, to a damper performance test apparatus for vibration damping an electric control panel of a power plant having improved reliability.
Description
The present invention relates to an apparatus for testing the performance of a damper for damping an electrical control panel of a power plant, which is capable of performing static and dynamic load tests on various axes (X, Y, XY) And more particularly, to a damper performance test apparatus for dustproofing an electric control panel.
In critical facilities such as nuclear / thermal power plants, dustproof dampers are used to prevent electrical control panel failure due to earthquake or external impact.
The performance test of such a damper is generally divided into a static load test and a dynamic load test. The static load test and the dynamic load test are again carried out by the axial force test of the damper, A horizontal test, and a damping resistance test.
At this time, since the vertical direction test and the horizontal direction test of the damper must measure the change amount of the damper with respect to the force applied to the damper by applying a force to the damper in different axes, one damper performs a horizontal test, And are respectively mounted on devices suitable for vertical testing. That is, individual devices required for each measurement are required to measure the performance of the damper.
FIG. 1 shows a conventional damper testing apparatus having the above disadvantages. Referring to FIG. 1, a conventional damper testing apparatus includes a main body supported on a floor, a first screw rod disposed on the front side of the main body and having a screw thread formed on the outer surface thereof, a first screw rod, A first guide member for guiding the movement of the first sliding member, and a second guide member for guiding the movement of the first sliding member, which is located below the first sliding member, A first load cell provided in the main body and measuring a pressing force of the vertical damper and having a lower fixture to which the other end of the vertical damper is fixed and a first motor provided on the upper portion of the main body and rotating the first screw rod A second threaded rod disposed on the upper side of the bed and formed with threads on the outer surface thereof, a second threaded rod coupled with the second threaded rod, A second sliding member having a first holding mechanism for moving to the left and right of the bed according to the rotation and gripping one end of the horizontal damper, a second guide member for guiding movement of the second sliding member, A second load cell provided in a portion of the bonnet which is provided in a portion of the bonnet which is located in the direction of the first screw rod to measure a pressing force of the horizontal damper and hold the other end of the horizontal damper, And a horizontal damper test section including a motor.
Various methods have been tried to solve the disadvantages of the above conventional test apparatuses (dampers performance tests for each axis must be individually performed), but in order to perform a vertical test, a horizontal load is applied to a fixed damper The horizontal load is transmitted to the actuator which urges the damper in the vertical direction, and the reliability of the test result is deteriorated.
Therefore, even if the performance of the damper is tested against the force applied to the various axes in one device, the force applied to measure the performance of the damper for any planned axis is influenced by the test equipment provided for the testing of the other axes There is a need for an apparatus for testing the performance of a damper for damping an electric control panel of a power plant having reliability.
