In addition to setting elastic vibration damping support for equipment generating vibration such as fan and water pump, flexible hose connection shall be used between fan and air duct, and air duct valve shall be manufactured with artificial data or canvas data
The vibration damping performance of electric butterfly valve shall be evaluated by vibration damping test
The vibration reduction test is usually carried out only when the electric butterfly valve is newly designed and trial produced, and it is not necessary to test the electric butterfly valve one by one after mass production; Just carry out type test
However, for electric butterfly valves that are particularly important or can only meet the technical requirements through adjustment in the vibration reduction test, they should be tested one by one
