Kunshan Hongxingchang Electronics Co

After years of development, a company that supplies silicone type rings and silicone large-size sealing rings with high temperature resistance has formed a comprehensive manufacturer with multiple varieties, multiple specifications, large stock quantities, and can customize various rubber sealing miscellaneous parts according to the special requirements of customers< br/>Manufacturer. The standards implemented by sealing products include French standards, German standards, Japanese standards, American standards, Chinese national standards, etc. The wire diameter of imported rings can be produced from any diameter, and the inner diameter can be customized from
. The sealing ring materials are all made from well-known brands such as the United States, Japan, and Germany. Such as perfluoroelastomer, fluorine rubber, polyurethane, rubber, hydrogenated rubber,
silica gel, etc. The temperature range varies from ~℃ depending on the material. And the products have outstanding performance in ozone resistance, high and low temperature resistance, strong acid and alkali resistance, wear resistance, and anti-aging.
All products comply with, and other certifications.
Two-twisted material imported ring
Imported material rubber
Working temperature limit ~ ℃ long-term use temperature recommendation ~ ℃ In order to meet the customer's requirements for low temperature resistance, the rubber material can be specially prepared, and the details can be further discussed with We communicate.
Performance characteristics: Oil-resistant, water-resistant, and wear-resistant. It is the most commonly used rubber sealing compound. Similarly, sealing rings with particularly high wear resistance can also be made according to the special requirements of customers.
In order to prevent the ring from being twisted and damaged, the following points should be noted
Use large-diameter rings in large quantities, and avoid using them as seals for large-diameter pistons
Seal the wire of the shaped sealing ring The diameter should generally be larger than the static sealing ring
The concentricity of the installation groove should be considered from the aspects of easy processing and no distortion
Under certain conditions, it can be considered to be used together with a back-up ring
Quantity Use materials with low friction coefficient to make shaped sealing rings
The cross-sectional size should be uniform, and lubricating oil or grease should be fully applied to the sealing part during installation
The surface roughness of the cylinder barrel and piston rod should be low.
3. Determination of important parameters in the selection of imported ring specifications
Determination of material performance
Where the sealing product will be used, whether it needs to be resistant to high temperature and high pressure, whether it needs to be oil-resistant and wear-resistant, whether it needs to be resistant to Strong acid, strong alkali, whether there are other special performance requirements, etc. Only when the specific performance requirements are clear
can the corresponding material be selected. Currently commonly used materials include EPDM rubber, rubber, polyurethane,/fluorine rubber, silicone, natural rubber, silicone fluorine rubber hydrogenated rubber, polytetrafluoroethylene neoprene, etc.
Confirm the hardness by pressure
During the design, you must pay attention to the matching of the hardness of the ring and the pressure. Otherwise, the sealing ring may be extruded, bitten, or otherwise unable to seal properly. Usually the hardness of the material is black,
or transparent or red, / black or brown, black, transparent or beige, etc. But the specific hardness to choose depends on the amount of pressure.
Determination of shrinkage
The amount of compression is another very important parameter in the selection of ring specifications. If selected improperly, the sealing effect of the sealing ring will not be achieved. The amount of compression of the seal is generally determined by its hardness and material.
If the hardness of the type ring is 100, then the amount of compression of the type ring is about 100%. In places with low pressure, the hardness of the sealing ring will be lower, and the amount of compression will be larger. On the contrary, if the type ring is used in places with high pressure, the hardness of the sealing ring will be higher, and the amount of compression will also be smaller. Some.
Confirmation of diameter and outer diameter
The ring specifications and dimensions only have three parameters: outer diameter, inner diameter and wire diameter. Outer diameter, inner diameter + * wire diameter. At present, in drawings and practical applications, it is mainly represented by inner diameter * wire diameter. It is also represented by
outer diameter * wire diameter, so please pay attention to it during application.
Confirmation of specification tolerance
Generally speaking, specification tolerances mainly include inner diameter tolerance and wire diameter tolerance. Specification tolerance mainly depends on the size. The larger the size, the larger the tolerance will be. For example, the national standard wire diameter tolerance is +/
and the tolerance is +/.
