Principle of brick machine conventional frequency conversion vibration
Aug 11, 2020
Its mechanical structure is that the motor drives the eccentric shaft through a synchronous gearbox, and the eccentricity and eccentric mass are fixed. Therefore, when a certain value of excitation force is to be reached, it can only be achieved by requiring it to reach a certain speed, as the eccentricity and quality cannot be changed. When making bricks with a relatively small amount of concrete, the excitation force still has to maintain such a benchmark, because if the rotation speed is low, although the excitation force is also low, the frequency also decreases. The quality of concrete molding mainly depends on two factors, the excitation force and the vibration frequency. The frequency of vibration reaches more than 4000 rpm, which can make cement liquefy faster. That is to say, even when making some bricks with a relatively small amount of concrete, a relatively large excitation force must be used to obtain a relatively large vibration frequency (because the eccentricity and mas...
