4.Background
a. Background of types of double mechanical seal
Double sided mechanical seal (i.e. types of double mechanical seal) refers to a sealing structure composed of two pairs of sealing end faces, which has higher safety and reliability compared to single end face seal, and is particularly suitable for toxic, flammable, explosive or high pollution risk working conditions. It can rely on the secondary seal to prevent medium leakage even when the primary seal fails through a dual protection mechanism, and is widely used in fields such as chemical, pharmaceutical, and petrochemical industries.
b. types of double mechanical seal classification and characteristics
Classified by spatial arrangement
This is the most core classification method that determines the overall structural layout of the seal.
Classification Structure Characteristics Applicable Scenarios Source
Axial double end face seal: The two sealing end faces are arranged in sequence along the axis direction. The common"face-to-face"or"back-to-back"arrangement is suitable for situations where sealing liquid needs to be introduced and pressure balance needs to be achieved, such as reaction vessels and centrifugal pumps
Radial double end face seal: Two sealing end faces are distributed radially in the same section, making the structure more compact and used in space limited equipment, such as some small pumps or rotary joints
c. Suggestions
When choosing types of double mechanical seal, comprehensive consideration should be given to:
Is the work pressure high? → Deciding whether to choose a balanced type
Is the installation space tight? → Does it affect the selection of radial or axial direction
Whether leakage is allowed → decide whether to equip a sealing system (such as GD tank)
Maintenance convenience requirements → It is recommended to adopt a modular design
