O rings factory manufacturer today
High quality hydraulic seals factory: Mechanical seals are engineered for most pumps, mixer and agitator applications in maintenance. In many cases the designs have been proven to be workhorses over years of use. In others seals must be designed for evolving industrial demands. The basic rotating face mechanical seal design is adaptable to serve a wide range of sealing applications including compressors. Standard mechanical seals can suit most requirements to temperatures of 500 degrees F and shaft speeds to 3600 RPM. The selection of secondary seal type often determines the temperature and chemical capabilities of the seal. The combination of materials used in the rotating and stationary faces define the abrasive resistance, and chemical resistance. Seal face combinations will also determine the amount of energy consumed by the pump, mixer, agitator or compressor. Seal faces can be balanced to permit higher pressure sealing. Balanced seals can seal pressures above 200 psi, or used in a multiple stages for higher pressures or especially severe fluid services. Special mechanical seals can be furnished to meet the most demanding of industrial applications considering pressure, temperature, speed or fluid. Discover additional info on spring seals.
A basic mechanical seal contains three sealing points. The stationary part of the seal is fitted to the pump housing with a static seal –this may be sealed with an o-ring or gasket clamped between the stationary part and the pump housing. Rotating and Stationary parts of a Seal – The rotary portion of the seal is sealed onto the shaft usually with an O ring. This sealing point can also be regarded as static as this part of the seal rotates with the shaft. The mechanical seal itself is the interface between the static and rotary portions of the seal. One part of the seal, either to static or rotary portion, is always resiliently mounted and spring loaded to accommodate any small shaft deflections, shaft movement due to bearing tolerances and out-of-perpendicular alignment due to manufacturing tolerances.
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.
Since the scraper seal is made of the special material, PTFE, it has an impurity immersion function. Therefore, when combined with the piston rod seal and the metal bushing, it can prevent damage to the piston rod and prevent the accumulation of oil pressure. It has a diameter range of 3-1600mm and a temperature range of -30°C + 200°C. The wiper scraper seal can operate at speeds of up to 5 m/s. It has high wear resistance, tear resistance, low-temperature resistance and good strength. Our wiper seals can be used in combination with piston seals and anti-wear rings to prevent oil in the cylinder from being mixed with foreign matter, which causes damage to the working seal. It is especially suitable for piston rods with a large diameter. Moreover, it has a wide range of applications, such as agricultural machinery, injection moulding machines, forklifts, cranes and so on.
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.

Due to the volume and weight limitations of the system, it is impossible to install an ideal filtration and cooling system. High temperature, high pressure, and high speed cause the hydraulic oil to deteriorate easily, and the mechanical parts are also prone to erosion and stains. There are many stains and impurities in hydraulic oil, but it cannot be thoroughly filtered, which is the aspect of endogenous stains. All kinds of dust in the working environment may be very large, and it will inevitably enter the hydraulic system in multiple ways, causing oil pollution, which is an external stain. Therefore, the sealing system is required to be resistant to stains.
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.
