Apparatus for damping vibrations in stock suspension flow |
摘要 |
Fibrous stock suspension preparation systems include moving parts that generate a vibration impulse flow in the outlet from the preparation system. A counter-vibration impulse generator is connected to the outlet pipe and includes a correcting impulse recorder also connected to the outlet pipe for sensing the vibrations of the flow therepast and for sending a signal to the counter-vibration generator to control the amplitude and/or the frequency of the counter-vibration generator. A further impulse recorder between the stock suspension preparation system and the first mentioned impulse recorder is also connected to the outlet pipe for providing a stock transit time correction signal for correcting the signal of the first mentioned impulse recorder.
