Oil cap can be installed to prevent general oil corrosion
The manufacturer knows that Dongfeng brand fan pneumatic butterfly valve air energy pneumatic butterfly valve transformer pneumatic butterfly valve air conditioning unit pneumatic butterfly valve damper ball valve pneumatic butterfly valve pneumatic balloon valve pneumatic butterfly valve is an elastic element composed of air chamber, elastic diaphragm and support plate. It is a sealed container with internal inflation, which uses the change of internal energy of air to achieve vibration isolation
The pneumatic butterfly valve of the air ball valve has a lower natural frequency (2.6~5.3Hz) and a higher damping ratio (0.06~0.08), so it can obtain a higher vibration isolation efficiency
The pneumatic butterfly valve of the air ball valve bears load changes, and the natural frequency of the system is roughly unchanged, so it has variable stiffness characteristics, so the center of gravity of the equipment does not need to be considered too much in the design of the vibration isolation device
