[ common problem ] What is the cause of the leakage when the newly installed mechanical seal is running?

The reason for the leakage of newly installed mechanical seal after it is put into operation is mostly the installation problem. 1) The designed face specific pressure is too small to meet the face specific pressure required by the mechanical seal; 2) The compression of mechanical seal spring is too small; 3) The roughness of mechanical seal end face does not meet the requirements; 4) The flatness of mechanical seal end face is not enough; 5) Mechanical seal ring under pressure and

[ Industry News ] Special mechanical seal

Special mechanical seal refers to the mechanical seal that is different from ordinary mechanical seal in terms of medium, pressure, speed, temperature, structure and use. It is also called high parameter mechanical seal in China. The mechanical seal is divided into ordinary and special types, which is convenient to describe the structure, working conditions and use requirements of mechanical seal. Therefore, some seal manufacturers list normal seal products, High loads are also listed

[ Company News ] Fitting and Analysis of Seal Face Topography Based on Stochastic Process

The face morphology of mechanical seal has a significant impact on the seal performance and life. The main characteristics of the surface morphology of the actual seal ring are that the local part has randomness, while the overall part has statistical laws, which are generally characterized by rental accuracy and correlation length. To solve this problem, this paper simulates the face topography of mechanical seals based on the stochastic process and time series theory
