It is a completely non-toxic, harmless, green, healthy and environmental protection product. 2、 Waterproof Silicone sealing ring has extremely high-quality sealing performance, can be completely sealed, and will not let a drop of water enter the sealing space. 3、 Characteristics The silica gel sealing ring has strong adaptability to the environment. After it is placed in a strong temperature heating, it can well maintain its original shape and state, so that it will not deform completely, and will not produce any harmful substances under the high-temperature environment. It has excellent tensile performance and can achieve the effect of continuous crack and no deformation under very strong tensile force. After long-term use, the color will not change, turn yellow or fade. It has very good corona resistance, arc resistance, high and low temperature resistance. It has good aging resistance and meets national standards. It has better elasticity than ordinary rubber, and can maintain better elasticity even at minus 60 or 70 degrees. It has very good electrical insulation performance, and it will not be affected even under high temperature conditions. 4、 Precautions It cannot be used in most thickened solvents, oil products, thickened acids and diluted sodium hydroxide.   This concludes today's content.

The seal is used to prevent the leakage of the working medium and the invasion of external dust and foreign matters. The sealing component is the seal. External leakage will cause waste of media, pollute the machine and environment, and even lead to faulty machinery and equipment and personal accidents. Therefore, seals and seals of hydraulic equipment are an important part. Its reliability and service life is an important index to measure the quality of hydraulic system. In addition to gap sealing, the use of seals is necessary to control the coupling between two adjacent surfaces of the gap between liquids through the minimum gap sealed below. O-ring is a circular rubber sealing ring with circular section. It is mainly used for mechanical parts to prevent the leakage of liquid and gas media under static conditions. In some cases, O-ring can also be used as a dynamic sealing element for axial reciprocating motion and low-speed rotating motion. Different materials can be selected according to different conditions The seal is used to prevent the leakage of the working medium and the invasion of external dust and foreign matters.

Delong Xingye sealing ring tells you how to store the O-ring?

Delong Xingye sealing ring tells you how to store the O-ring?

O-ring is a common rubber sealing ring with a wide range of application. The O-ring will be invalid due to the change of its physical characteristics when it is exposed to the hazards of various environmental factors, such as oxidation, sunlight, pyrogen, moisture source, wet cooling, product oil or organic chemical organic solvent, so how to store the O-ring? Delong Xingye seal ring manufacturer tells you: 1. The O-ring shall not be exposed to natural light. It is strictly prohibited to put it in a wet and cold storage room, so as to prevent the seal ring from accelerating aging and losing sealing characteristics. 2. The O-ring shall also prevent radiation sources, insects and rodents. It is strictly prohibited to touch with acids, alkalis, solution agents, vegetable oils and other liquids and vapors. Moreover, all equipment causing reactive oxygen species shall not be used when the O-ring is stored. 3. The O-ring must be stored one meter above the pyrogen. It is strictly prohibited to bear force, stretch or other methods. The product cannot be suspended 4. O-rings are generally packed in bags, and the reasonable storage period is generally more than 2 years. After mastering the storage standard, Delong Xingye seal will explain how long the O-ring can be stored. The storage life of the seal ring is determined by the raw material type and storage standard of vulcanized rubber, The storage life of each raw material sealing ring is below: 1. Polyurethane materials and thermosetting plastic raw materials for 4 years 2. Nitrile rubber, esterified nitrile rubber and chloroprene rubber for 6 years 3. Ethylene propylene rubber 8 years 4. Fluorine glue, silica gel and fluorine silicone rubber for 10 years 5. Perfluorinated rubber for 20 years 6. PTFE has no deadline Shenzhen Delong Xingye Seal Technology Co., Ltd. has a history of more than 10 years in the rubber seal industry. Relying on its strength in fluid seal technology and special rubber product manufacturing, it has summarized a set of development system suitable for the seal industry. At the same time, the development concept centered on customer demand makes Delong resistant to chemical corrosion, wear resistance, high and low temperature It has strong practical solution ability in resisting special media and provides advanced and reasonable sealing solutions for many customers.

Construction machinery can not be separated from the oil cylinder, and the oil cylinder can not be separated from the seal. The common seal is the sealing ring, also known as oil seal, which plays the role of isolating oil and preventing oil from overflowing or passing through. Common sealing rings for hydraulic cylinders are the following types: dust ring, piston rod seal ring, buffer seal ring, guide support ring, end cover seal ring and piston seal ring. Piston rod sealing ring The piston rod seal ring, also known as the u-cup, is the main piston rod seal. It is installed inside the end cover of the hydraulic cylinder to prevent hydraulic oil leakage. The piston rod seal ring is made of polyurethane or nitrile rubber. In some cases, it needs to be used with the support ring (also known as the retaining ring). The support ring is used to prevent the seal ring from extrusion deformation under pressure. Piston rod seals are also available in a variety of variants. Buffer seal ring As an auxiliary piston rod sealing ring, the buffer sealing ring is used to protect the piston rod in case of sudden increase of system pressure. There are three common types of buffer seals. Type A is a one-piece sealing ring made of polyurethane. Type B and type C are two-piece, which are used to prevent seal extrusion and allow the seal to bear higher pressure. Piston sealing ring The piston sealing ring is used to isolate the two chambers of the hydraulic cylinder and is the main seal in the hydraulic cylinder. Usually two-piece, the outer ring is made of polytetrafluoroethylene or nylon, and the inner ring is made of nitrile rubber. There are also many variants, including the use of bronze coated with polytetrafluoroethylene, etc. Polyurethane u-cup is also used on single acting oil cylinder. That's all for today's sharing. It will also bring more interesting knowledge and content. Delong Xingye will also share small knowledge and skills of sealing products. Interested partners remember to pay attention
