Mechanical seals are precision and complex mechanical components. The following editor will introduce the selection method and basic principles of mechanical seals.

Mechanical seals are one of the most precise and complex mechanical basic components and are the key components of various pumps, anti-chemical pumps, mechanical seals, synthetic 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, use, etc. The following editor will introduce the selection method and basic principles of mechanical seal to you.

Mechanical seal selection method:

Mechanical seals are based on different working conditions and media properties. Textile printing and dyeing mechanical seals include high temperature and low-temperature mechanical seals, high pressure and corrosion resistance mechanical seals, particle-resistant mechanical seals, and mechanical seals suitable for light hydrocarbon media that are easily vaporized. , mechanical seals with different structural types and materials should be selected according to different uses.

The main parameters for selection are: sealing cavity pressure (MPa), fluid temperature (°C), working speed (m/s), fluid characteristics, cartridge mechanical seal, and effective space for installing the seal.

Mechanical seal selection principle:

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, determine whether to use rotary or static, hydrodynamic or non-contact.

3. According to the temperature and fluid properties, determine the friction pair and auxiliary sealing materials and correctly select the lubrication, flushing, heat preservation, cooling, and other mechanical seal circulation protection systems.

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.

The above is about the selection method and selection principle of mechanical seal, I hope it will be helpful to everyone.
