Structural characteristics of sealing ring for liquefied petroleum gas

Taking petrochemical and oil refineries as examples, let us introduce the characteristics of typical hydraulic seal rings for vaporized medium pumps. DSH Seals tells you that there are many pumps that work near the boiling point of the medium, such as light hydrocarbon pumps, liquefied gas pumps, liquid ammonia pumps, hot water pumps and other hydraulic seal ring pumps.

So, what are the structural characteristics of a hydraulic seal ring for liquefied petroleum gas?

1. The hydraulic sealing ring for liquefied petroleum gas adopts multi-point flushing, which is evenly distributed along the circumference, less deformation, better heat dissipation, and uniform and stable end surface temperature than the general single-point flushing, which is beneficial to the lubrication, cooling and phase stability of the hydraulic seal ring. , Can quickly reduce the heat transfer rate of the liquid to the surrounding liquid, increase the heat transfer coefficient, and help stabilize the liquid film.

2. All hydraulic seals for liquefied petroleum gas adopt the characteristics of balanced hydraulic seal structure, and adopt a suitable area ratio to keep them within the appropriate range of film pressure coefficient variation, so that abnormal phenomena such as gas shock or gas spray will not occur. .

3. Of course, for the sake of safety, in addition to the main hydraulic seal, he also installed a secondary seal hydraulic component that has the functions of throttling, leakage reduction and insurance. These tasks are all done for liquids such as light hydrocarbons to leak into the atmosphere, and the shaft seal is formed into frost, which makes the shaft seal wear out and cause greater leakage, and even seal ring accidents. A brief introduction to the structural characteristics of hydraulic seals for liquefied petroleum gas.
