[Three rain valve to recommend Star Products - Mechanical seal] Description: When using acoustic emission technology to monitor the operational status of the mechanical seal, acoustic emission sensors are generally mounted in direct contact with the stationary ring stationary ring seat. AE signals generated from the end face of the stationary ring and stationary ring through the seat spread sensor, this distance at least twenty-three centimeters to more than a dozen centimeters mechanical seal, especially the large journal mechanical seals, acoustic emission signals in the transmission process also often subject to interference from other signals produced by the mechanical parts, so the collected acoustic emission signal separation and extraction become an essential component. , [Three rain valve to recommend Star Products - Mechanical seal] Description: acoustic emission refers to a material or surface deformation due to internal damage and the sudden release of strain or transient elastic waves can produce. Some researchers also called the stress wave acoustic emission emission (Stress Wave Emission H7N-65 mechanical seal, SWE). Mechanical seal dynamic and static rings are two core elements, dynamic and static ring face exposure to normal operation of the mechanical seal plays a decisive role. In actual operation of mechanical seals, because of the end face of power, heat distortion and affect other disturbing factors, can make change happen face contact, causing the collision. When a collision occurs, the collision of the static ring elastic deformation of the stress wave emission H7N-50 mechanical seals, namely acoustic emission. Directly and fracture mechanisms elastic deformation wave source, commonly referred to as a typical acoustic emission sources. Fluid leakage, friction, impact, burning, magnetic domain walls running the deformation and fracture mechanisms, etc. and not directly related to another type of acoustic emission source H7N-60 mechanical seal, known as the secondary acoustic emission source, mechanical seal face formed by friction AE source belong to the latter. Acoustic emission signal having a large dynamic range, the displacement amplitude of from 1 × 10 -15 m to 1 × 10 -9 m, 106 has a magnitude range; acoustic emission wave frequency range is very wide, from the secondary audio the audio until ultrasonic frequency, including several Hz to several MHz; its amplitude variations of the object from the microscopic to the large scale macroscopic fracture dislocation.
