Related Introduction
Selection method of mechanical seal:
According to different working conditions and medium properties, mechanical seals include high temperature and low temperature resistant mechanical seals, high pressure resistant and corrosion resistant mechanical seals, particle resistant mechanical seals and mechanical seals suitable for light hydrocarbon media that are easy to vaporize. Use mechanical seals of different structural types and materials.
The main parameters of the selection are: seal cavity pressure (MPA), fluid temperature (℃), working speed (M/S), characteristics of fluid mechanical seal, and effective space for installation of the seal.
