The damper is an elastic element that connects the device to the base to reduce and eliminate transmission from the device to the base.
The specific forms include: steel ball valve pneumatic butterfly valve, metal ball valve pneumatic butterfly valve, ball valve pneumatic butterfly valve and various composite damping devices. Please use the appropriate equipment support when using.
When designing and applying dampers,
(1) Meet the weight and volume requirements of damper equipment.
(2) It has certain damping characteristics;
(3) Be able to withstand the change of temperature and other environmental conditions (temperature, corrosive fluid, etc.);
(4) Be able to bear the specified load;
(5) It can provide the required amount of vibration reduction; The commonly used pneumatic butterfly valves are metal ball valve pneumatic butterfly valve and ball valve pneumatic butterfly valve. The former is characterized by stable performance, large bearing capacity, low natural frequency (less than 5 Hz), small damping coefficient, small horizontal stiffness, high-frequency noise transmission, etc. The latter has a large damping coefficient, which is conducive to passing through the resonance region and absorbing all three directions. It has better high-frequency noise and is easy to form. Easy processing, low bearing capacity, applicable temperature - 40 ° C-70 ° C. The life expectancy is about five years. Ball valve pneumatic butterfly valve is usually used for loaders. 1. The principle of determining the stiffness of pneumatic butterfly valve The vibration of the engine has six degrees of freedom, such as front and rear left and right, up and down, yaw, pitch and roll (the displacement in X, Y and Z) around the direction and rotation of three axes), as well as the elastic support device.
Six degrees of freedom should be considered. When arranging elastic supports (damping pads), the direction of the interference force, the center of gravity of the device and the geometric dimensions of the elastic support device should be considered. When the interference force passes through the center of gravity of the device and the direction is vertical, as long as the elastic support (damping pad) device is symmetrically arranged according to the center of gravity, the elastic support device will be subjected to the same stress. When the frequency of the interference force is greater than the natural frequency of the vibration isolation system composed of the device and the elastic support device, the environment around the device can obtain good vibration isolation effect. When the mass distribution of the support object is uneven and the elastic support device cannot be symmetrically distributed according to the center of gravity. The same type of damping pad with different stiffness can be used to make the damping pad closer to the center of gravity with greater rigidity.
