The vibrating platform is widely used in metallurgy, coal, chemical industry, building materials, medicine and scientific research industries, and is an important basic equipment for national economic construction. The working principle of the vibrating platform is mainly to use the vibration motor excitation as the vibration source to make the platform produce periodic vibration, and use the self-synchronization of the exciter or controlled forced synchronization to make the working platform produce directional amplitude vibration.
The main structure of the vibrating platform includes three parts: the table, the vibrating device and the shock absorbing device. The countertop is the part that carries the material, which requires sufficient strength and rigidity, and is kept level. The vibration device includes a vibrating motor and a spring support device, the vibrating motor provides power, and the spring support device plays the role of cushioning and shock absorption. The shock absorber is divided into two types: rubber shock absorber and air spring shock absorber, the rubber shock absorber is lower and is suitable for small vibration platforms, and the air spring shock absorber is higher but has a good vibration isolation effect and is suitable for large vibration platforms.
The parameters of the vibration stage include frequency, amplitude and eccentricity. Frequency refers to the number of vibrations per unit of time, usually measured in hertz, generally speaking, the higher the frequency, the greater the energy of the vibration, but it also leads to a decrease in the amplitude of the vibration. The amplitude refers to the maximum displacement of the vibrating platform table, which is an important parameter to measure the vibration intensity, and is selected according to different process requirements. Eccentricity refers to the distance between the axis of the rotor of the vibrating motor and the center of gravity of the machine, and the amplitude and frequency of vibration can be changed by adjusting the eccentricity.
When selecting and using a vibrating platform, it is necessary to consider it comprehensively according to the actual situation. For example, for occasions that require good vibration effect, a vibration platform with a large amplitude can be selected; For occasions that require high efficiency, a vibration platform with a lower frequency can be selected; For occasions that require good vibration isolation, a vibration platform with good shock absorption can be selected. At the same time, it is also necessary to pay attention to the installation and maintenance of the vibrating platform, regularly check the connection and working status of each component, and ensure the normal operation and service life of the vibrating platform.
In short, as an important industrial equipment, the structural parameters and working principle of the vibrating platform are the key factors to ensure its normal operation and meet the process requirements. Understanding and mastering these parameters and principles can help to better select and use the vibrating platform, improve production efficiency and product quality.
