Description

technical field [0001] The invention relates to a friction damping device, in particular to an intelligent hydraulic friction damping device installed on the front, rear, left, and right outer sides of an industrial vibrating screen and controlled by PLC. Background technique [0002] The industrial vibrating screen uses the motor to drive the vibrator on the vibrating screen to generate vibration. Its vibration frequency is much higher than its own system frequency, so it works very stably, has high screening efficiency, and is widely used. However, the vibrating screen has to go through the resonance point from start to normal work, and then to stop, and it will generate resonance, which is an inevitable phenomenon, but the severity of the resonance depends on the length of time it passes through the resonance point. During the period from motor startup to normal operation, the time for the vibrating screen to pass the resonance point is short, and the impact of resonance ...
