Common sense and use of mechanical seal selection
Mechanical seals are one of the basic mechanical components with precision and complex structure, and are the key components of various pumps, reaction synthesis kettles, turbo compressors, submersible motors and other equipment. Its sealing performance and service life depend on many factors, such as model selection, machine accuracy, correct installation and use, etc.
1. Selection method
Depending on the working conditions and the properties of the medium, mechanical seals include high temperature-resistant, low-temperature-resistant mechanical seals, high-pressure and corrosion-resistant mechanical seals, particle-resistant mechanical seals, and mechanical seals adapted to easily vaporized light hydrocarbon media, etc. The use of mechanical seals of different structural types and materials is selected.
The main parameters of the selection are: sealing cavity pressure (MPA), fluid temperature (°C), working speed (M/S), fluid characteristics and effective space for sealing installation.
The basic principles of selection are:
1. According to the pressure of the sealing cavity, determine whether the sealing structure is balanced or unbalanced, single-end or double-end, etc.
2. According to the working speed, it is determined to adopt rotary or static type, hydrodynamic type or non-contact type.
3. According to the temperature and fluid properties, determine the friction pair and auxiliary sealing materials, and correctly select the mechanical seal circulation protection system such as lubrication, flushing, heat preservation, cooling, etc.
4. According to the effective space of the installation seal, it is determined to use multiple springs or single springs or wave springs, built-in or external-mounted.
