Hydraulic machine hydraulic system hydraulic seal
Hydraulic machine hydraulic system is the most important component, representing the heart of the hydraulic machine. If the hydraulic system leaks can cause fluid leaks, pollution of the surrounding environment, affecting work efficiency, increased production costs and so adversely affected. Control measures must be taken immediately. Now we understand why the total hydraulic system leak from the roots. [View Details]
Rubber O-ring important reference
Now it seems that the rubber O-ring manufacturers more and more varieties of rubber O-ring is also very much, but not particularly clear classification, most of the business is based on their dealers the necessary products for production, and form their own brand. Most of them are mold and possible errors are all customer data base to decide, and not some normative. Rubber O-ring in the technological aspects of production we need to check and make changes, then secured the abutment to keep tidy, if not kept neat butt joints, then it is too much trouble, it needs to be modified fixed in the final weld .

Singwax Rubber seals for customer service
Rubber seals are signs production projects in Singwax. Rubber seals must be produced by a professional and technical personnel to operate, this is a big company can focus on producing 12-year capital. In our daily life, large railway, aviation, small bolt, tables and chairs, you can see the standard figure, a wide variety of different specifications, various industries have different needs, so demanding. The standard of quality, how to decide the safety of us, life and industrial production, as manufacturers of 12 years attention standard parts supply service, Singwax always strictly control product quality, scientific quality management, never let anyone "unqualified" into the market.

Material characteristics of hydraulic seal
Hydraulic seals in the operation of machinery and equipment (application) in the process, always encounter a lot of bad factors, such as cracking, deformation, leakage, poor hardness performance, anti pressure is too low and so on.This is our most aware of the adverse factors have with you in the selection of sealing material (material) has a very relationship, such as temperature, hardness, tensile strength, elongation, resilience, compression permanent deformation properties.

Application of mechanical seal elastic component in rubber seal.
The suspension system is subjected to a vertical load and a component which is subjected to the impact caused by the mitigation and suppression of the road surface.Its function is to bear and transmit the vertical load, ease and restrain the impact caused by uneven pavement.Elastic components are sort into metal and nonmetal two parts by difference materials.

Cautions and design considerations of rubber O-ring
Pipe joint chamfering sealing rubber O-ring is a junction of seal, the O-ring will be fitted to a produced groove by chamfering and then squeeze through the shell to create a seal. What should concern when design rubber O-ring product is that must be slightly stretched, appropriate to reduce the amount of compression, appropriate to increase the fill rate. Chamfering is generally 15 � ~ 30 �, according to the working pressure selected, under pressure, to an angle close to a small value. On the contrary, whichever is greater. Its chamfered is easy to use, operate, manufacture and process characteristics seal between the fitting and the hydraulic valve, so it�s widely use on sealing pipe joints. This article focuses on the design and selection of sealing the chamfered [View Details]
Atomic oxygen may do effect to the leakage of rubber hydraulic o ring.
The structure of rubber hydraulic o ring is simple, safe, so it also is used extensively, spacecraft and aircraft always use that seal structure. The silicone rubber is made of polymer, the effect which a variety of environmental conditions in space and especially atomic oxygen to its seal performance can�t be ignored [3,4]. The air is mainly made of N2? O2? Ar? He? H and AO in LEO, the atomic oxygen content is the highest , about 80%. As the particle of having the highest content in LEO, atomic oxygen is formed by the light induced decomposition of oxygen molecules at wavelengths less than 243 nm. Not only atomic oxygen has strong oxidation property, but also atomic oxygen impacts material surface in a speed of 7~8km/s when the vehicle runs at the track speed in LEO, the average kinetic energy of the impinging material is up to, 5eV 4~,so it makes the performance of material changes, then the sealing effect changes.As to the long sealing with little leakage, we have to study the regularity of effect of atomic oxygen on sealing performance.

Rubber ring size and the use of calculation
Hydraulic O-ring is a rubber element is used widely, mainly in the packers, wellhead equipment, gauges and other equipment as a seal. Hydraulic O-ring sealing performance depends mainly on the merits of a rubber material corrosion resistance in harsh corrosive environments. At high temperature and pressure conditions of high levels of H2S and CO2, O-ring seal hydraulic failure mainly as a rubber material swelling and aging, resulting in a hydraulic O-ring shape changes, restitution, inelastic hydraulic seals, hydraulic seals elastic contact stress between the ring and the equipment is released, resulting in acid gas leak. Sour gas leak will cause the wellbore annulus with the wellbore [View Details]
Y-type rubber seals investigate structure
Y-type rubber seals are often used in hydraulic or pneumatic cylinder, since only one-way seal, its product structure is provided within the outer lip lip A and B in order to obtain a better initial sealing effect, engineers design products should, in its inner and outer lip leave some amount of interference. After loading the trench work, two lip seals only the groove diameter portion in contact with the sliding surface to produce a certain amount of prestressing, play a role in sealing. In operation, the fluid pressure at the sealing lip is deformed in the circumferential direction, completely fit on the surface of the piston rod and the cylinder mating surface, it acts as a seal. Its design working pressure Y type rubber seals of related design parameters with different working pressures need to be adjusted accordingly. Y-ring design parameters include, the amount of interference lip, lip thickness a, the outer lip of the cylinder and the piston rod or the inner lip angle A, the size of the roots, as well as the inner and outer lip angle B.

Combined with the use of hydraulic seals
Due to a combination of machine clamping cylinder, cylinder head Seal hydraulic rod seal ring easily damaged, change frequently, poor sealing effect, leakage of hydraulic oil, environmental pollution, high costs. Now through comprehensive analysis and demonstration and field trials, the use of O-type, Y-type hydraulic seal ring combination improved to solve the leakage problem. Clamping pressure is usually required in 3.5 ~ 4.0MPa, the hydraulic system and reversing the impact is relatively large, there is a drawback valley portion cracking Y-type hydraulic seal ring itself. Repeated high-voltage transient tearing under severe stress concentration due to breakdown. In addition, as the hydraulic seal ring itself quality problems, after poor part of the quality of the oil seal hydraulic seal accord, week breakdown, resulting in a large amount of oil.
