Xin Huaxu seal device by the support ring, ring, pressure ring composed of three parts. V-shaped seal the standard angle is 90 °, also used in special occasions 60 °. The bearing ring is an important part of the bearing V-ring seal, the section of thick and strong, accurate size, concave angle and V-shaped ring the same (90 °) or slightly larger, so that the ring placed stable. In the free state, the outer diameter of the lip of the V-ring is larger than the inner diameter of the packing chamber, and the inner diameter of the lip is smaller than the outer diameter of the piston rod. In this way, the assembly will have a certain deformation. Due to the role of the supporting ring, this deformation occurs only in the tip of the lip, and the pressure in the contact area, even without the application of compression force, the lip can seal a certain internal pressure. Because the lip has a "self-styled" role, when the media working pressure, the lip change contact shape and increase the contact stress, lips and sealing surface is more closely fit to achieve sealing effect, the media pressure increased contact stress corresponding Lt; / RTI & gt;

Xin Hua Xu sealed in accordance with the height of the two lips are the same, but also can be divided into shafts with unequal high-lip Y-ring, the hole with the unequal lip Y-ring and shaft hole common high-lip Y-type seal ring. Y-ring manufacturing materials are different, but also can be divided into nitrile rubber Y-ring, fluorine rubber Y-ring, polyurethane rubber Y-ring and so on.

Hydraulic o - ring application and use of know - how
Hydraulic O-ring is mainly used for static seal and reciprocating seal, hydraulic O-ring is widely used in daily life, reliable sealing, small leakage, running stability, long life and other advantages are widely used in the industry with the pharmaceutical industry seals , Seals for the nuclear power industry, seals for the natural petrochemical industry, seals for the aerospace industry, etc. Rotating fluid machinery in the field of hydraulic O-rings, which include a floating seal ring and an auxiliary hydraulic O-ring are sealed system squadronsEnd hydraulic O-ring side of the most important features of one of the components. In the auxiliary hydraulic O-ring for compensating movement, the hydraulic O-ring's own elastic deformation, the rubber seal ring and the contact seal can occur relatively static, non-continuous slip (partial slip) and complete Slip and other complex state of micro-motion, which is the o-type rubber seal of the fretting characteristics. The choice of hydraulic O-ring material is essential, the general flexibility of the seal material can only meet the hardness of static use, and in this high-temperature conditions of frequent movement, we must choose high temperature, wear resistance, anti-aging sealing material.
Avoid using old seals. When using the new sealing ring, also carefully check the surface quality, to determine no holes, protrusions, cracks and grooves and other defects and have enough flexibility before use. Installation, should first strictly open all parts of the hydraulic system, the best use of special tools to prevent sharp edges of the metal will scratch your fingers. Replace the ring, it is necessary to strictly check the seal groove, remove dirt, grinding groove bottom.
Hydraulic O-rings and other rubber products after processing and vulcanization is easy to produce dimensional changes, which may be due to such as molding shrinkage or extrusion expansion relaxation caused by various factors, these changes in the design and manufacture of a product mold and mouth Type such components should be identified and considered.
Hydraulic O-ring storage room temperature is preferably below 30 ?, to avoid high-temperature aging of the seal; must be stored in a sealed package to avoid moisture and dust in the air contact; must avoid strong light to avoid the seal air In the ozone erosion or premature aging.
Hydraulic O-rings are used where required in the final application and should be limited to those dimensions that are considered critical. The higher the precision used, the more stringent the control that must be performed in the manufacturing process, and therefore the higher the cost .

Fluorine rubber hydraulic seal product stability
Fluorine rubber hydraulic seals with a high degree of chemical stability, high temperature resistance, aging resistance, is the elastic medium in all the best resistance to media performance of a. Fluorine rubber and high temperature performance of silicone rubber, can be said to be the best of the current elastomer (hereinafter referred to as fluorine plastic).
Fluorine rubber hydraulic seal in the color-based operation, based on the original recipe to do the adjustment to achieve the desired goal is, the method is basically the same, but the color need to start from scratch to develop formulations and adjust the color, and colorIt is in the original recipe on the basis of addition and subtraction masterbatch and components, the color closest to the target and a good record of the recipe.
Oil Seal The lip seal is known as the rotary shaft lip seal, the role of the transmission components in the need to lubricate the components and output part of the isolation, to prevent oil leakage. Fluorine oil seal as the unique properties of fluorine rubber, so the fluorine rubber seal has a good advantage.
The face of the fluorine rubber produced by the appearance of the hydraulic seal is not smooth, we have to find the reasons for its occurrence, and timely correction, this can avoid a large number of surface is not smooth hydraulic seal output, resulting in a large number of waste materials and affect efficiency. In the process of the need to strengthen control.
Fluorine rubber hydraulic seals, although good material properties, but a long time in different areas of application of the aging time is different, there are some high-temperature local application is the phenomenon of aging is relatively fast, such as long-term few years will appear in time Cracks, in the industrial manufacturing which the temperature reaches a certain height, the parts will increase the role of oxygen diffusion to accelerate the oxidation of fluoride plastic material reaction, which is our common heat effect, leading to deformation of fluorine rubber aging one of the common phenomenon,The process should be to maintain long-term climate temperature modulation, appropriate cooling water and so on.

Material Structure of Hydraulic Seal
Seal The choice of hydraulic seal material for its sealing performance and service life is of great significance. The performance of the material directly affects the performance of the seal. In addition to the general requirements of the hydraulic sealing ring material, the hydraulic seal should also pay attention to the following conditions, elastic and resilient; appropriate mechanical strength, including the expansion of strength, elongation and tear strength. Stable performance, swelling in the medium is not easy, heat shrinkage effect (Joule effect) small. Easy to shape, and can maintain the precise size. Does not corrode the contact surface, does not contaminate the medium and so on.
Water Seal The hydraulic seal is used to seal the end face of rotary motion to prevent dust, water and other contaminants from entering the bearing or sealing system. (The basic form of VA. VS, special conditions, optional VE VL type). Conventional materials for products (NBR) NBR rubber. FKM can also be supplied according to the environment.
Hydraulic seal V-shaped water seal because of its simple structure, easy to use, high reliability, making the groove and install the design work greatly reduced, therefore, V-shaped water seal in the industrial engineering, water treatment equipment, rolling machine , Lathe and other fields to obtain a wide range of applications.
Water seal hydraulic seal ring installation does not need to install the chamfer. V-shaped water seal for the elastic body, can be pushed after the push on other parts, V-ring can be stretched up to 20% maximum, so easy to install (Figure 1).
In many cases, the V-shaped seal can be mounted with a simple tool that rotates the shaft and pushes or centers the V-shaped water seal with a bladeless tool to the correct mounting position.
If the replacement of V-shaped water seal involves the removal of several other parts of the time-consuming operations, you can cut V-shaped water seal into two parts, placed in the appropriate location, and then bonding materials and tools to connect the two parts together, Note that the connection is not stretchable.

Xin Huaxu seal of the V-and Y-type
Xin Huaxu seal specifications yx-type seal ring y-ring standard y-ring seal size section of the seal was Y-shaped, is a typical lip seal. Widely used in reciprocating dynamic sealing device, its life is higher than the O-ring. Y-ring for the working pressure of not more than 40MPa, the working temperature of -30 ~ 80 ?.
Xin Huaxu seals in accordance with the length and width of the cross-section of different, can be divided into wide-type Y-ring, narrow Y-ring and Yx-ring and so on. Wide section of the Y-ring pressure resistance is slightly smaller than the narrow-type Y-ring, can only apply to P <20MPa working environment, and narrow-type Y-ring can be used for working pressure P <32MPa occasions.
Xin Huaxu seal device by the support ring, ring, pressure ring composed of three parts. V-shaped seal the standard angle is 90 °, also used in special occasions 60 °. The bearing ring is an important part of the bearing V-ring seal, the section of thick and strong, accurate size, concave angle and V-shaped ring the same (90 °) or slightly larger, so that the ring placed stable. In the free state, the outer diameter of the lip of the V-ring is larger than the inner diameter of the packing chamber, and the inner diameter of the lip is smaller than the outer diameter of the piston rod. In this way, the assembly will have a certain deformation. Due to the role of the supporting ring, this deformation occurs only in the tip of the lip, and the pressure in the contact area, even without the application of compression force, the lip can seal a certain internal pressure. Because the lip has a "self-styled" role, when the media working pressure, the lip change contact shape and increase the contact stress, lips and sealing surface is more closely fit to achieve sealing effect, the media pressure increased contact stress corresponding Lt; / RTI & gt;
Xin Hua Xu sealed in accordance with the height of the two lips are the same, but also can be divided into shafts with unequal high-lip Y-ring, the hole with the unequal lip Y-ring and shaft hole common high-lip Y-type seal ring. Y-ring manufacturing materials are different, but also can be divided into nitrile rubber Y-ring, fluorine rubber Y-ring, polyurethane rubber Y-ring and so on.
Working speed range: the use of small eyes rubber production is 0. 01 ~ 0.6m / s; with fluorine rubber production, the 0.05 ~ 0.3m / s; using polyurethane rubber production, compared with 0.01 ~ lm / s. Y-ring sealing performance, service life and the working pressure when the different ring limit, are better to polyurethane rubber material.
