What are the inspection methods of electric butterfly valve?
The shock absorption performance of the electric butterfly valve shall be verified through the shock absorption test. The vibration reduction test usually stops only when the electric butterfly valve is newly designed and trial produced, and it is not necessary to stop the test one by one for the electric butterfly valve after mass consumption; Just stop the typing experiment. However, for the electric butterfly valves that are particularly important, or the electric butterfly valves that must stop conditioning in the vibration reduction test before reaching the technical request, they should be tested one by one. It is better to stop the vibration reduction experiment on the whole machine, so the experimental condition is the practical working condition; The vibration reduction experiment can also be stopped on a special vibration reduction test bench, that is, to imitate the practical working conditions, artificially manufacture the vibration source, and compare the difference between the electric butterfly valve and the electric butterfly valve to evaluate the advantages and disadvantages of the electric butterfly valve.
According to different conditions, vibration sources can be manufactured by various excitation offices, such as the reciprocating displacement excitation generated by the eccentric rotating to drive the slider, the centripetal force excitation generated by the unbalanced rotor, the compressed air blower, the loudspeaker, the electromagnetic induction, or the special vibration table, etc. The parameters to be measured during vibration test include frequency, amplitude, velocity, acceleration, etc., and sometimes the stress or strain of some parts of the machine. Different industrial departments and different machine products have different requirements for vibration.
