In view of the excessive wear mechanical seal slurry pump in project and inconsistency between theoretical actual wear, this article studies pump. article, a numerical model based on thermal deformation is established. The hardness, coefficient dry friction sealing ring were obtained through experiments, morphology was collected by ultra-depth microscope. precise calculation realized, depth under single multiple field conditions obtained. formula optimized adding correction index, end face...
Rolling bearings are widely used in machinery and equipment, how to extract the feature identify fault of rolling have become essential issues for ensuring safe operation rotation machinery. The signals present nonlinear non-smooth characteristics which introduce certain challenges extracting signal. To completely features signal, this study proposes a novel extraction method based on quadratic wavelet packet energy entropy (QWPEE) t-distributed stochastic neighbor embedding (t-SNE) bearing...
Aiming at the problem of mechanical seal failure due to serious wear and tear in operation, numerical model thermal–solid coupling ring is established by taking friction sub-material as research object, hardness, coefficient, coefficient different soft-ring materials are obtained a test verify accuracy wear. Additionally, temperature field deformation calculated, effects material parameters, such elasticity modulus thermal conductivity, on temperature, relative deformation, axial trend...
Under the condition of modern information technology, scale battlefield electromagnetic increases exponentially, which makes environment more complex, and brings great opportunities challenges to development anomaly detection algorithms in complex environment. Since research this field is still its infancy work system not strong, paper sorted out analyzed relevant literatures at home abroad, summarized traditional methods deep learning respectively according different algorithms. At same...
Spiral groove mechanical seal is one of the most favorite method when considering extreme conditions in terms high speed, temperature and pressure industry. In this paper, distribution field deformation friction pair interface spiral was studied based on numerical simulation method. The results showed that sealing ring relatively large with respect to film thickness. On other hand, maximum primary mating less affected by but influence different large. Therefore, needed be controlled production.
