The function of seals is mainly reflected in preventing medium leakage and protecting the normal operation of equipment, with the significance of improving equipment safety, reliability, and durability.

The function of seals

Preventing medium leakage: By physical isolation or chemical barriers, liquid, gas, or solid media are prevented from leaking from the inside of the equipment to the outside. For example, mechanical seals prevent process fluid leakage, and car seals prevent rainwater and dust from entering the car.

Protecting equipment safety: By using sealed structures to reduce friction losses and mechanical vibrations, the service life of equipment can be extended. For example, mechanical seals can reduce energy consumption and failure rates of pump equipment.

Maintaining environmental stability: In specific scenarios such as nuclear power plants and spacecraft, seals can prevent the leakage of radioactive substances or high-temperature media, avoiding environmental pollution or safety accidents.

The significance of seals

Determining equipment performance: Sealing performance directly affects equipment volumetric efficiency and mechanical efficiency, for example, improving mechanical sealing efficiency can reduce energy consumption by 3.6% -5.6%.

Reduce maintenance costs: Reduce frequent repairs caused by leaks, for example, mechanical seal maintenance costs in petrochemical enterprises account for 70% of total maintenance costs.

Ensuring production safety: In high-risk industries such as chemical and nuclear power, seal failure may lead to major accidents such as explosions and poisoning.
