The invention discloses an automatic damping method for a spraying system, which comprises the following steps: 1) installing several vibration sensors on all vibration sources in the spraying system; 2) connecting the data output ends of all vibration sensors with the filter and the spectrum analyzer, and the filter and the output of the spectrum analyzer are connected to the PLC, and the output of the PLC is connected to the PC; 3) the spectrum analyzer obtains the original spectrum data, and stores the original spectrum data in the PLC and the PC ; 4) When the spraying system is working, the vibration sensor will detect the vibration source in real time and send the data to the spectrum analyzer. The spectrum analyzer converts the received data into real-time spectrum data, and then transmits it to PLC and PC. Compare the spectrum data with the original spectrum data; 5) PLC connects all motors and control valves, and controls the motors and control valves according to the comparison results, and balances the motors by accelerating or decelerating the motors by draining or venting the air Flow, to achieve the purpose of shock absorption.
Description
technical field [0001] The invention relates to the field of fault diagnosis of a spraying system, in particular to an automatic damping method for a spraying system. Background technique [0002] In the spraying system, because there are many vibration sources, abnormal vibrations also occur continuously. The existing solution is to detect the amount of vibration through the vibration sensor, which is used to directly judge the abnormal vibration near the vibration source; after the abnormal vibration is found, it is often necessary to disassemble the vibration source for maintenance, such as fans and water pumps. [0003] However, dismantling the vibration source for maintenance cannot solve the vibration anomaly in which the natural frequency and its multiplier in the spraying system resonate with the vibration source. Contents of the invention [0004] The object of the present invention is to provide an automatic damping method for a spraying system to solve the prob...
