[Three rain valve to recommend Star Products - Mechanical seal] Description: (1) Finite Element Analysis of the S-type group and the number of bellows diaphragm stiffness relation between HJ92N-25 mechanical seal, and the establishment by the least squares method the S-shaped bellows stiffness mathematical model, the S-shaped bellows stiffness provides a convenient computing. (2) Under the same circumstances waveform HJ92N-30 mechanical seal, with the increasing number of groups of the diaphragm, the diaphragm stiffness decreasing, flexible as possible, in the actual project can select the number of suitable film group needed bellows in order to improve the mechanical seal assembly overall flexibility of mechanical seals, vibration absorption line, play a good damping effect.
