Production Description

1. Feature

The double end structure is easy to install.
The multi spring structure ensures uniform force distribution on the sealing end face, good axial compensation performance, and no contact between the spring and the medium, making it suitable for various corrosive media

2. Material

We can provide materials not mentioned above to meet the requirements of different occasions. If needed, please contact Asino company

3. Aplications

Oil and gas, chemical, metallurgical, pharmaceutical, food, water treatment

4.Background

Will the 'small spring' of the double mech seal be blocked by impurities during use, leading to failure?

a. Impurities affect the core path of double mech seal small springs

Indirectly blocking the active space of the spring

If the flushing liquid or process medium in the sealed chamber contains solid particles or fibrous substances (such as wear residue of rubber seals, impurities in the medium), these impurities may enter the sealed chamber with the fluid and accumulate in the compression/reset space of the spring. Long term accumulation will limit the free extension and contraction of the spring, resulting in its inability to provide sufficient end face compressive stress, ultimately leading to seal leakage.

Impurities exacerbate spring corrosion/wear

If the medium is corrosive (such as acid, alkali, salt solution), impurities will accelerate the corrosion of the spring metal material, leading to a decrease in spring elasticity and fracture; If the medium contains hard particles (such as slurry, abrasive), impurities will form abrasive wear between the spring and the sealing chamber wall, and between the spring and the transmission components, damaging the structural integrity of the spring.

Impurities cause chain failures in the sealing system, indirectly leading to spring failure

Impurities may first damage the sealing end face (such as particles embedded in the end face forming a"grinding wheel effect", grinding the sealing face), leading to increased wear and clearance of the end face. At this point, the spring needs to continuously compensate for a larger gap. Long term overload will accelerate spring fatigue and ultimately lose its elastic compensation ability.

b. Typical manifestations of double mech seal small springs

Loss of elasticity: The spring cannot push the sealing end face tightly together, resulting in medium leakage from the end face gap;

Structural damage: Spring breakage, deformation, loss of compensation ability, periodic separation of sealing end face, exacerbating wear;

Function limitation: The spring is stuck by impurities and cannot compensate synchronously with the normal movement of the shaft, resulting in local wear on the sealing end face.

c. Key measures to prevent the impact of impurities

Control the cleanliness of the medium

Optimize the flushing/isolation liquid system

Reasonably select sealing element materials

Standardized operation and maintenance

In summary, although the small spring of the double mech seal is not directly"blocked", impurities can indirectly cause spring failure through blocking the active space, corrosion and wear, overload compensation and other paths. Therefore, controlling the cleanliness of the medium and optimizing the operation of the sealing system are the core of extending the life of the spring.
