my country has approached or has reached the international level in the theoretical research of two-phase sealing of mechanical seals, and some aspects have its uniqueness. If it is combined with practical applications and formed into a series of products, it is very beneficial to solve the various sealing problems of the current light hydrocarbon pumps.

Vigorously promote the application of cartridge (manufacturer has assembled and debugged) mechanical seals. Most of the domestic seal failures are caused by improper installation and use. If you use a manifold, you can avoid such problems.

The shaft of the stirred tank is mechanically sealed, and its operating conditions are harsh, and the viscosity of the medium is often variable, sometimes containing particles. In addition, the shaft has a large aspect ratio and is easy to swing, so it is easy to leak and has a low life. In order to adapt to this working condition, it is necessary to research and develop a mechanical seal that can move several millimeters in the axial and radial directions without leakage.　　240.html,
