Self-excitation vibrating prevention feature of mechanical seal

摘要

(57) Abstract Objective In sealing sleeve aspect S of mechanical seal 10The noise which absorbs the ri direction self-excitation vibration, is called the seal squealGeneration is prevented. Constitution With coil spring 12 energization shiruri which is doneThrough vibration-proof erasutoma component 22 to ngu 14, the annular mass bodyTo provide 21, this annular mass body 21 and the vibration-proof erasutoma componentFrequency of vibration of the normal mode of the damping damping type 20 which consists of 22, shiruriIn configurating to the frequency area of the self-excitation vibration of ngu 14 the tsuThe sea by the stick slip in of the te and the sealing sleeve aspect SThe self-excitation vibration of ruringu 14 is absorbed.
