Mechanical seals improve analysis solution
Mechanical rubber seals may be between the sleeve and the shaft, between the ring and the sleeve, between static and dynamic ring seal between the cap and the sealing pump; pump mechanical seal a wide range of leak intuitively difficult to identify and judge shall long-term management, infrastructure maintenance practice, leak symptoms were observed and analyzed, judged, in order to draw the right conclusion. There are four reasons for the failure of the seal rubber seal that is corrosion, heat damage rubber seals, rubber seals wear seals and installation, operation failure caused by such factors.

XinhuaXu rubber O-rings have introduced
Rubber O-ring seal for a variety of forms: static seals, dynamic seals, suitable for various uses materials, dimensions and grooves have been standardized, interchangeable. [View Details] -
Hydraulic load failed O-ring, for example, load failed diameter sealing surface strain and the groove, cylinder port and flash as well as deformation, aging, cracking hydraulic O-ring. Particularly unqualified hydraulic O-ring diameter is not too large or too small, too small margin compression is not enough, but to squeeze too much loaded when assembled, will cut broken seal. So you want to check the following requirements before installing angle is introduced according to drawings whether chamfer or round sharp edges; if the inner diameter of deburring surface for contamination; whether seals and components have smearing grease or lubricating fluid (to ensure that the elastomer media compatibility, recommended to lubricate the sealed liquid) may not use grease containing solid additives such as molybdenum disulfide, zinc sulfide.

Hydraulic seals are divided into: a shaft seal, hole sealed, dust-proof seal, guide ring, fixed seal, rotary seals;

High temperature resistance, chemical solvents Hydraulic O-rings
With industrial development of reliability, safety and other requirements on the rise, high temperature, high friction, and other harsh working environments, the hydraulic O-ring material in continuous improvement, high temperature resistance, chemical materials increasingly solvent update FKM has the characteristics of high temperature, oil resistant to many chemicals and erosion. Viton O-ring in a hydraulic amount has also increased rapidly. [View Details] -
U hydraulic seal is a seal for sealing purposes. Because of its U-shaped cross-section, it is known as U-ring, the English name of U-ring.

The new O-ring seal joints are longer life
Traditional rubber O-rings are assembled by prestressing to achieve sealing effect, in the case of the parts to be sealed require frequent installation and removal, the process of installation and removal greatly increased wear and damage to the rubber O-ring, seriously affecting life.

How to extend the life of hydraulic seals
Let's extend the service life of hydraulic seals can start from the material, Xinhua Xu developed hydraulic seal is a high hardness of the rubber or glass fibers with polyurethane vinegar, poly Thalidomide, Teflon and other materials, friction small loss in oil pressure rises too high degree of tightness, long service life.

Hydraulic O-rings Xinhua Xu production
To Hydraulic O-rings to maintain good results, understand the hydraulic O-ring hardness, long-term use of nuclear tests we learned under what circumstances the best use of what hardness hydraulic O-ring. [View Details] -
Material silicone rubber seals
Silicone rubber seals can be for a variety of large-scale environment, he has advantages and disadvantages, silicone rubber price is not generally high, in order to use the economic benefits of alternative materials. [View Details]
