Rod seals manufacturer and supplier 2024: The Fluid Film – In most mechanical seals the faces are kept lubricated by maintaining a thin film of fluid between the seal faces. This film can either come from the process fluid being pumped or from an external source. The need for a fluid film between the faces presents a design challenge – allowing sufficient lubricant to flow between the seal faces without the seal leaking an unacceptable amount of process fluid, or allowing contaminants in between the faces that could damage the seal itself. This is achieved by maintaining a precise gap between the faces that is large enough to allow in a small amounts of clean lubricating liquid but small enough to prevent contaminants from entering the gap between the seal faces. This micro-gap is maintained using springs and hydraulic force to push the seal faces together, while the pressure of the liquid between the faces (the fluid film) acts to push them apart.

Types of Mechanical Seals – Several types of mechanical seals are available. Some of the popular ones include: Balanced and unbalanced seals; Pusher and non-pusher seals Cartridge seals. A mechanical seal consists of rotary and stationary faces running against each other. These faces apply a closing force against each other using springs and the pressure generated from the process fluid. This way, a seal is formed to prevent the fluid from leaking between the rotating shaft and the pump housing. Mechanical seals can be selected based on the type of pump application. Choosing the wrong seal can affect pump performance and lead to damage and costly repairs. An unbalanced mechanical seal is preferred if the pump needs to operate at a lower pressure. However, high pressure pumping applications require balanced mechanical seals. Balanced seals also perform better in high temperature operating conditions. Cartridge seals require less maintenance but are more expensive, hence used for limited applications.

Key points of engineering mechanical seal design: Select a reasonable sealing scheme, focusing on the above requirements. First of all, the dustproof performance must be good. More than 80% of the failures of the hydraulic system are directly or indirectly derived from the stains in the system. Choose the best seals For seals of the same structure, the product quality of each company varies greatly. On the whole, the quality of large foreign seal companies is relatively stable, but the probability of encountering fakes is too high. Sometimes the so-called direct supply is not reliable. In terms of domestic seals, most of them are not very good, but at present, some manufacturers’ products have been chasing or even surpassing imported products, with stable and reliable quality, such as tetrafluoroethylene and rubber seals produced by Damson Sealing.

The bearing seal maintains lubrication where needed and helps protect the working part from abrasive particles and corrosive moisture. The seals are precisely configured to provide extremely low friction and excellent contamination resistance. It is perfect for high speed or low torque equipment as well as dusty environments. Moreover, the seal is reasonably designed to provide superior resistance to foreign particles.

It adopts the most ideal design and improved sealing performance and can minimize the high strength of local stress. This type of seal is designed to simplify installation and reduce particle generation. Moreover, it can be quickly and easily installed and removed to facilitate hardware assembly. It perfectly combines a custom seal design, proprietary bonding technology, and excellent plasma resistance developed for semiconductor applications. And its unique structure can minimize common installation problems.

Our piston seals are designed to provide excellent leak control. We guarantee that it can perfectly meet the user’s requirements for low friction, compactness, precise configuration and simple installation. It is designed for fluid power applications. It is made of compound materials with high performance, which guarantees excellent wear resistance and excellent extrusion resistance for the seal. It is designed to be suitable for almost all fluid media and is highly resistant to oxidation and corrosion. It has excellent dynamic and static sealing performance and can even work under dusty industrial environments. Moreover, it has strong adaptability to various working conditions and can adapt to a fast, high-pressure working environment. At the same time, it has unparalleled performance in extreme temperature environments.

Destroy the leak: The working conditions of the sealing part are relatively bad, the thermal deformation is large, it is often subjected to vibration, impact, improper installation, excessive tightening force, repeated use, compression deformation, internal stress concentration, damage beyond the fatigue strength, material aging, deterioration, etc. will cause damage to leaks. This kind of leakage has the greatest impact and great harm, so it is necessary to strengthen prevention.

We own a number of invention patents and leading production process. The R&D teams have the ability to design and develop seals for various of complicated working condition of sealing system. We have already passed the certification of ISO 9001 and IATF 16949.
