[ 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 ] Mechanical seal for reaction kettle

Reaction kettle is one of the key equipment in chemical, chemical fiber, petrochemical, pharmaceutical and other production processes. Compared with pumps and other rotating machinery, it has unique use conditions and operating characteristics. Therefore, although the mechanism of kettle mechanical seal is the same as that of pump mechanical seal, kettle machinery has its own system due to its particularity. Reaction kettle generally consists of kettle body, agitator, transmission mechanism and shaft seal

[ Company News ] Sealing of mixer, agitator and reactor

1、 CDMSC ™— The integral design of the canned double end integral static ring compensated convection seal ring improves the stability of the seal ring under high temperature and pressure conditions, prolongs the service life of the seal under such conditions. The drive contact area of the seal ring is large, preventing damage to the seal ring when the equipment starts or stops under viscous liquid conditions. The internal clearance is large, maximizing the density

[ 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
