Background:

Structural principle and classification characteristics of double mechanical seals

Dual mechanical seal through two independent sealing friction side work in synergy, the core principle is consistent with the single-end face seal, both rely on the vertical axis rotating friction device, through the fluid pressure, elasticity and auxiliary seal to achieve leak-proof function. Its structural characteristics and classification are as follows:
Core composition: includes dynamic ring, static ring, spring, sealing ring and other components, some types need to be externally supplied with the sealing fluid system, to improve stability through sealing, lubrication and cooling cycles.

Classification:
Pressure of the sealing fluid system: divided into high-pressure double sealing (sealing pressure higher than the medium pressure 0.01-0.03MPa) and non-pressure double sealing (sealing pressure is atmospheric pressure or slightly lower than the sealing cavity pressure).
Massage friction side layout: can be divided into radial type, face-to-face type, back-to-back type and serial type, where the back-to-back type is easy to disassemble and a wide range of applications, often considered a narrow sense of double-ended mechanical seal.

Installation and maintenance of dual mechanical seals
Installation Key Steps
1. Sealing ring selection: according to the characteristics of the medium, temperature and pressure, choose carbide, ceramic, silicon carbide and other materials to ensure that the specifications and equipment match 2.
2. Installation order: Position the bearing seat and sealing cavity → Install the sealing ring and fix → Install the spring (first small and then large) → Adjust the nut and the clamping force → Install the sealing cap and check the flatness.
3. Adjustment and inspection: it is necessary to ensure that the sealing surface fits tightly, the spring pre-tensioning force adapts to the shaft speed, and the sealability is verified by the compressed air leakage test and oil leakage test after installation.

Maintenance and troubleshooting
Daily maintenance: Regularly check the sealing surface wear, bolt tightness and lubrication, clean impurities and replace wear parts in a timely manner.

Common troubleshooting:
Leakage: Check if the sealing ring material is suitable or the installation is skewed
Overheating: Adjust the spring pre-tension or check the cooling/lubrication system cycle

Application Scenarios and Special Types of Dual Mechanical Seals
Typical Application Areas
Conventional industrial scenarios: Suitable for light hydrocarbons, viscous fluids, polymer media, etc., especially in devices with limited radial installation sizes or smaller sealing cavities.
High-risk environment: the back-to-back type double seal is often used in sulfur recovery devices, and the serial type is suitable for medium-load rotational speed equipment with small shaft diameters and limited axial dimensions.
Explosion-proof double-end mechanical seal
Features: Explosion-proof design on the basis of conventional double seal, to prevent explosive, flammable, toxic media leakage, to ensure the safe operation of the equipment in dangerous environments.
Application: Widely used in petrochemical, pharmaceutical, food processing and other occasions with strict safety requirements, it is the core sealing solution for handling high-risk media.If you want to view other products,pls see this website & www.aefluidtec.com/
