[Three rain valve to recommend the star product - Mechanical seal] Description: fluid friction. Process mechanical seals running M74N-175 mechanical seal, with the rise of the spindle speed, the mechanical seal face friction within (ie, the dynamic between the ring), will gradually form a sliding bearing the same stable lubricating film M74N- 120 mechanical seal, this thin lubricating film thickness is much greater than the seal face roughness can be completely separated from two ends. At this point there is no direct contact between the end face of the basic friction only by the viscous fluid shear generated, thus friction and wear between the end faces are greatly decreased M74N-135 mechanical seal, power consumption and heat are also reduced accordingly. This condition is called end surface friction fluid friction, acoustic emission signals generated by the relatively weak, small amplitude, low frequency. [Three rain valve to recommend the star product - Mechanical seal] Introduction: mixed friction. With the decrease of the end surface waviness, static ring end clearance becomes smaller, then the local dry friction neither raised support mechanical seal, and the lack of a boundary friction nanoscale uniform surface texture, but contact between the surface the simultaneous presence of several friction over the state mixed friction situation. Actual operation in the industrial field, the vast majority of ordinary mechanical seals work in mixed friction conditions, and only in light-load, high-speed or high-viscosity conditions of the machine will be in the whole film sealing fluid lubrication friction.
