Abstract

The invention relates to a vibration test system of a locomotive cooling tower. The vibration test system comprises a test bed and a power supply cabinet, wherein the test bed comprises an industrial personal computer module, a lower computer module and a data acquisition and processing module; the power supply cabinet comprises a three-phase constant-voltage power supply module, a frequency converter and a main control module; and an object to be tested is a cooling tower fan. When the vibration test system works, a piezoelectric sensor acquires acceleration vibration signals of the cooling tower fan in real time, the acceleration vibration signals are subjected to data processing, then enter a data acquisition card, and are displayed for warning through intuitional numbers and waveformson an industrial personal computer; the vibration signals of acceleration, speed and displacement exceed set threshold values, the system automatically gives an alarm for prompting; and the rotating speed of the cooling tower fan can be adjusted by changing frequency settings on the industrial personal computer so as to adapt to different fan types. The vibration test system can effectively detect the vibration signals of the acceleration, the speed and the displacement, so that the vibration condition of the cooling tower is accurately reflected, the accuracy of a vibration test is improved,and the safety and the reliability of production are improved.

Description

technical field [0001] The invention relates to a vibration test system of a locomotive cooling tower, which is a vibration signal collection and test system of a cooling tower. Background technique [0002] At present, most domestic technical solutions for collecting and testing vibration signals use hand-held vibration testing instruments for measurement. Its main disadvantage is that due to the great randomness in the measurement of the handheld vibration tester, it is difficult to keep the test points uniform, and the direction is difficult to keep perpendicular to the measured surface; the accuracy and reliability are low. Contents of the invention [0003] The purpose of the present invention is to overcome the weakness of the hand-held vibration tester, and provide a locomotive cooling tower with high test accuracy, strong reliability, which can effectively detect vibration signals such as acceleration, speed and displacement, and accurately reflect the vibration of...
