One or two air valve isolator components need to be selected at each fixed point to support the load. Generally, the design pressure should be within the range of 0.4~0.55Mpa. Usually only single or double curvature air valve isolator components are used. Select the close shock frequency, and determine the valve efficiency according to the natural frequency of the selected pneumatic ball valve.
Pneumatic ball valves must be used at the given design height. The isolation percentage of double curvature capsule parts is higher than that of single curvature capsule parts (that is, the valve effect is better). This is because the air internal volume of the double curvature capsule is larger than that of the single curvature capsule.
The key to determine the isolation efficiency lies in whether the detailed vibration problem you are facing is to choose the load and vibration frequency scale described in the guide.
Therefore, once the preliminary selection of pneumatic ball valve model is made, you can refer to the function parameter table of this model to determine the required internal pressure value and the obtained isolation percentage.
For example, on the four corners of the vibrating screen, isolate the total load of 7.4T, and the vibrating device vibrates at the speed of 850cpm and the total stroke of 8mm.
