Oil cap can be installed to prevent general oil corrosion
The manufacturer knows that Dongfeng brand fan electric butterfly valve air energy electric butterfly valve transformer electric butterfly valve air conditioning unit electric butterfly valve damper butterfly valve electric butterfly valve air butterfly valve electric 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 electric butterfly valve of air butterfly valve has low natural frequency (2.6~5.3Hz) and high damping ratio (0.06~0.08), so it can obtain high vibration isolation efficiency
The electric butterfly valve of the air butterfly valve bears the load change, and the natural frequency of the system is roughly unchanged, so it has variable stiffness characteristics, so it is not necessary to consider the center of gravity of the equipment too much when designing the vibration isolation device
