Application of hydraulic seal elements
In the hydraulic system, reciprocating seals is one of the most common seal. Power cylinders are used in reciprocating seals on the piston and the cylinder, the piston rod and the cylinder head and a variety of slide valve. The gap is formed by a cylindrical rod and the cylinder bore, the cylinder bore axial movement of the rod. Sealing function limiting axial fluid leakage. When used in reciprocating seals, hydraulic seals and self-sealing effect of the pre-seal and static seal when the same, and since the hydraulic seal their elasticity, therefore, has the ability to automatically compensate for the wear and tear.

We understand that the rubber O-ring
Advantages The rubber O-rings are: (1) high-pressure rubber O-ring both high temperature resistance, abrasion resistance and have mechanical seals for pumps, able to work under harsh conditions; (2) high-pressure rubber O-ring to have a very strong corrosion resistance, habits can be a variety of media; (3) high-pressure rubber O-ring anti-extrusion ability, long life, can be more useful to carry forward the seal.

Air compressor special rubber seals
A new generation of Teflon seal skeleton rubber seals could be 30 times that of traditional rubber seal, the life of up to 10,000 hours, the maximum shaft speed 30m / s, the maximum pressure 3.5MPa (B type), operating temperature of -100 ? -350 ?, the coefficient of friction rubber seal oil seal 1/40, is a veritable king seal!

Tetrafluoroethylene-coated rubber O-ring
Tetrafluoroethylene-coated rubber O-ring seal and rubber elasticity and chemical resistance of PTFE combine organic, it is composed of a silicone or fluorine-colored plastic inner core and relatively thin FEP or PFA overcoat combination into, PTFE-coated rubber O-ring seal with excellent performance. Rubber O-ring wear resistance, chemical resistance and anti-poor gas permeability, pure PTFE O-ring hardness higher resistant to compression but less flexible. Covered with FEP / PFA rubber O-ring has a good antiswelling properties and chemical stability (unless by alkali metals, fluorine and some of the halide erosion at high temperatures) in the vicinity of the rubber Oring has good elasticity, FEP / PFA friction coefficient is very small (only 0.1 to 0.2), but also has excellent resistance to gas permeability, these properties make tetrafluoroethylene coated rubber O-ring can really use in harsh environments.

Hydraulic O-rings prevent leakage and corrosion
Hydraulic O type external sphere of influence factors include the characteristic parameters of the sealing gap, manufacturing precision, surface properties, the reciprocating motion distance and frequency, special l raw hydraulic O-ring and the pressure medium and means, such as pressure, speed, work time, stop time and temperature and so on.

Xinhua Xu hydraulic seal performance characteristics of our attention
Material seals according to seal media to choose. Between the seal material and the working medium have a good compatibility, the working medium to withstand corrosion, wear, and does not occur the precipitation, crystallization phenomena and chemical reaction media work. [View Details]
Rubber piston seal characteristics
The piston is reciprocating piston internal combustion engine, etc., compressor and pump mechanical cylinder along the cylinder axis reciprocating machine parts. Piston has a disk-shaped, cylindrical and cylindrical three forms. Closed end face of the piston to withstand the pressure of the working fluid, and with the cylinder head, cylinder wall defining the combustion chamber or compression volume. Mounted on the piston or piston ring seal to prevent fluid leakage gum. [View Details]
