[Three rain valve to recommend the star product - Mechanical seal] Introduction: mechanical seal to ensure low leakage rates even to achieve zero leakage, then end clearance to be small enough. By the end surface roughness, such as parallelism and installation factors, the movement ring face is likely to be a collision or friction, so the study of friction conditions between the end faces is very important. Mechanical seal when normal operation M74N-125 mechanical seal, due to the different sealing medium, internal structure and operating conditions (speed, pressure, temperature, etc.), according to the viscous force hypothesis, the following four kinds of friction may occur between the state of the seal faces. [Three rain valve to recommend the star product - Mechanical seal] Description: fluid friction. Process mechanical seals running M74N-105 mechanical seal, with the rise of the spindle speed, the mechanical seal face friction within (ie, the dynamic between the ring), and the slide will slowly form a stable lubricating film bearing the same mechanical seal lubricating film thickness of this very much larger 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 M74N-135 mechanical seal friction only by viscous fluid shear generated, thus friction and wear between the end faces are greatly reduced 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.
