The shock absorption performance of the butterfly valve shock absorber needs to be identified through the shock absorption test. The vibration damping test is generally only carried out when the shock absorber is newly designed and trial produced, and after mass production, each butterfly valve shock absorber will not be tested; Only the final type test will be carried out. However, for special electric butterfly valves, or shock absorbers that must be adjusted in the vibration reduction test to meet the technical requirements, they need to be tested one by one.
The vibration damping test should be carried out on the whole machine, so that the test conditions are the actual working conditions; The vibration damping test can also be carried out on a special vibration damping test bench, that is to say, simulate the actual working conditions, artificially create the vibration source, compare the difference between the shock absorber not installed and the shock absorber installed, so as to evaluate the quality of the shock absorber. According to different situations, different vibration sources can be artificially simulated for testing. Different equipment has different requirements for vibration. Jiuao designs different detection methods and selects different detection equipment according to the use of different products to achieve the best valve effect.
