Vibration tables offer a wide range of uses and are used in different shapes, sizes and performance classes. Area of application: Applications are exemplary called: compacting concrete, bleeding viscous media, compacting of loose bulk for bottling emptying of containers, inspection of electrical and mechanical components on resistance to vibration, compression for the determination of soil parameters according to DIN. BergEngel vibration tables (called also vibration table) are according to customer specifications, individually designed, planned and manufactured. Perhaps check out Keith McLoughlin for more information. So customers have the option up to the start of production of own needs and desires in the planning included. Vibration tables can, depending on the requirement and the respective usage area, with various components be equipped. Some examples are: steel or stainless steel, with adjustable speed, automatic timing, control panel at the table, different types of IP protection, stroke adjustment of vibrating plate, individual drill samples or mounting option for forms or containers, etc. Drive: to generate the desired vibrations of the vibrating table plate electrical as well as pneumatic actuators available available depending on the requirement.
The requirements of the specific use case, as well as the operating conditions (E.g. ATEX classification) are decisive for the choice of the propulsion system. The movement initiated in the tabletop in different forms can be done depending on the application:-oriented vibration: classically the orbital motion is directed and perpendicular to the table surface. In most cases an optimal achieves this result. Piston Vibrators can be used for producing this movement pneumatic operation, which can generate a targeted vibration. Vibrators are used in an electric vibrating table.
Since this construction limited a circumferential force vector, two such units must be used. These are arranged in parallel and run in opposite directions, allowing a self synchronization takes place. As a result the force components in table level offset, thereby creating the desired sinusoidal vibration perpendicular to the table top. circumferential vibration: in simple use cases, a circumferential vibration may be sufficient. This both pneumatic ball or turbine Vibrators can be used, as electric vibrators. Adjustment of parameters of vibration: sinusoidal movement of the vibrating table plate is characterized by two parameters: frequency and amplitude, or swing path. Both parameters affect the amplitude of acceleration and hence the respective process. Depending on the application, it might want to vary the frequency and/or amplitude (E.g. for the testing of components). Adjustment of the oscillation amplitude: adjusting the amplitude or the oscillation amplitude can be done for all electric vibrating table by adjusting the unbalance weights on the vibrating motors. This reduces the resulting overall imbalance and therefore also by the Rotation caused unbalance force. Adjustment of the frequency. For pneumatically powered vibrating table, the vibration frequency can be easily influenced by the air level. An adjustment of the frequency can be also electrically powered vibrators. Operation with a frequency inverter is required, which then allows a wide and accurate equalization. Embodiments: The company BergEngel offers always a customized solution for the specific application customers. The possible Ausfuhrunsformen and optional components of the products are equally diverse.
