[Three rain valve to recommend the star product - Mechanical seal] Introduction: When the mechanical seal friction operation will produce energy information between M74N-38 mechanical seal, static ring, and acoustic emission technique can accurately reflect the seal face friction energy information generated through analysis and identification of the acoustic emission signals can be realized on the mechanical seal face contact as well as the work of the entire sealing device status monitoring. [Three rain valve to recommend the star product - Mechanical seal] Description: Acoustic emission refers to internal or surface material deformation or damage as a result of a sudden release of strain can produce transient elastic waves. Some researchers also called acoustic emission stress wave emission (Stress Wave Emission, SWE). Mechanical seal dynamic and static ring are two core elements, dynamic and static ring face exposure to normal operation of the mechanical seal plays a decisive role. In the course of the actual operation of the mechanical seal M74N-33 mechanical seal, the end face of the force due to thermal deformation and the impact of other interfering factors, can make change happen face contact M74N-25 mechanical seal, causing the collision. When a collision occurs, the collision occurred at a static ring elastic deformation stress wave transmitter letters, ie acoustic emission. Directly and fracture mechanisms of deformation of elastic wave source, often referred to as a typical acoustic emission sources. Fluid leakage, friction, impact, burning, and other non-magnetic domain wall running directly related to the deformation and fracture mechanisms Another acoustic emission source, known as the secondary acoustic emission source, sound mechanical seal face friction emission sources are formed after person. Acoustic emission signals having a large dynamic range, the displacement amplitude can be from 1 × 10 -15 m to 1 × 10 -9 m, has a range of variation of the order of 106; acoustic emission wave frequency range is very wide, from the secondary audio the audio until the ultrasound frequency, including several Hz to several MHz; its amplitude variations of the object from the micro to large macroscopic fracture dislocation.
