The circulation system where the gas side flows into the oil side and flows into the air side from the oil side, the dragging surface is well moistened, which can avoid damage and expansion, thus there is no leakage. The basic theory of sealing is that there are layers of specific wetting films in the center of a dynamic soft sealing and mutual mating surface. Under all normal circumstances, this layer of wetting film is relied on to surpass the sealing purpose and add the service life of hydraulic seals. Silicone in silicone products is a natural raw material. Due to its strong softness and toughness, it can be made into different hardness and has been liked by everyone. More and more manufacturers have developed silicone products to make them flexible in seals, silicone tableware, silicone toys, silicone pet products, silicone household products, etc., and appear in various industries in different colors and shapes. Compared with the traditional materials in the market, silicone products have a long service life and do not need to be replaced frequently in the application. Especially in the application of seals, it is easy to produce wear problems. Silicone seals can avoid these problems well. At the same time, they will not produce deformation, yellowing and peculiar smell problems in the environment of up to 240 degrees, which can keep the density of silicone products unchanged in the original state, in this way, people will be stronger in the security of the application. Silicone sealing ring can be used in many articles because of its richness. Today, I want to talk to you about the use of silicone sealing ring on gear oil. Gear oil, as the sealing liquid, has the necessary steam pressure. When using silicone sealing ring, it is necessary that the ductility of silicone sealing ring is better, and it can be integrated into the deformation caused by such steam pressure and kneaded into shape. In the hydraulic transmission system, the damage of gear oil (liquid) to the sealing characteristics of hydraulic seals, in addition to the compatibility of material/rubber seals, the viscosity of refined oil, the change of viscosity with temperature, the rate of reciprocating (rotating) exercise, the working pressure and the material, strength, geometric appearance and surface lubrication of the shaft, engine cylinder or hydraulic cylinder, silicone keys and the structure of its hydraulic seals and other elements that damage the occurrence of the wetting film and the characteristics of the film all damage the actual sealing effect. Generally speaking, the occurrence of continuous wetting film can obtain the desired actual sealing effect.

Rubber sealing rings are widely used in various industries such as hardware and plastic, silicone keys for water supply and drainage, fire fighting, shipping, pharmaceuticals, household appliances, toys, electronics, sports equipment and sanitary ware. We can see them everywhere in our life and work. However, how to install rubber sealing rings and what precautions are easily ignored by us, while the neglect of details often leads to big problems, therefore, it is necessary for us to understand what are the precautions for the installation and use of rubber sealing rings. 1. Before installation, all parts of the opened hydraulic system should be strictly cleaned, and special tools should be better used to prevent sharp metal edges from scratching fingers. 2. Do not install the wrong direction and damage the lips. If there are scars of more than 50μm on the lips, it may cause obvious oil leakage. 3, no sealing ring can be forced to install, to pay attention to the degree of fit, can not be knocked in with a hammer, but to use special tools to press the sealing ring into the seat hole, and then use a simple cylinder to protect the lip through the spline part, before installation, to apply some lubricating oil on the lip. 4, to prevent extended use, rubber sealing ring of the expiration of the period, the timely replacement of new sealing ring, and to ensure the size of the same, dynamic seal of rubber sealing life is generally 3000~5000h, should be timely replacement of new sealing ring. 5. Avoid using old rubber sealing rings. When using new rubber sealing rings, carefully check the surface quality to make sure that there are no defects such as small holes, protrusions, cracks and grooves, and they are flexible enough before use. The sealing ring should be careful not to deform the rubber sealing ring when loading into the groove. The sealing medium can be considered on the groove and O-ring. If you do not use the rubber sealing ring, try not to open the original packing to prevent the rubber sealing ring from being damaged by dust or falling into the impurities on the surface of the rubber sealing ring. If you want to save the rubber sealing ring, you should try to avoid direct sunlight or placed near the boiler and other high temperature heat sources to avoid premature aging of the rubber sealing ring. During the preservation process, the rubber sealing ring is white powder, so you don't need to worry about it. It will not affect the performance and service life of the rubber sealing ring.

In the production process, if the electric welding or polishing treatment of the screen frame is uneven and has burrs, the rubber sealing ring also has shock absorption and buffering effect on the upper and lower screen frames in addition to the actual effect of tightness. If the edge is uneven or the polishing treatment is incomplete during the production and processing of the screen frame, unevenness or burrs will appear, and the continuous friction of the screen frame during the operation of the machine equipment will cause the dense components to crack. What factors will affect the storage time of rubber sealing ring. 1. Sealing ring temperature: 5°C ~ 25°C is the ideal storage temperature. Avoid contact with heat sources and sunlight. Before use, the seal removed from low-temperature storage should be placed in an environment of 20°C. 2. Humidity: The relative humidity of the warehouse should be less than 70% to avoid over-wet or over-dry, and no condensation. 3. Light: Avoid sunlight and strong artificial light sources containing ultraviolet rays. Anti-ultraviolet bags provide better protection. It is recommended that the windows of the warehouse be painted with red or orange paint or film. 4, radiation: to avoid ionizing radiation damage to the seal. 5. Oxygen and ozone: Rubber materials should be avoided from being exposed to circulating air. This can be achieved by packaging, winding, storing in a closed container or other appropriate methods. Rubber sealing ring is not only used for sealing machinery and equipment, but also has a very important function, that is, to reduce the friction and vibration in the middle of the components, and to maintain the machinery and equipment. Silica gel, pc polycarbonate, vulcanized rubber rubber, spring, etc. can be used as hydraulic seals of vibrating screens. According to the investigation, some customers will crack the hydraulic seals when using them, in fact, the reasons for this situation are likely to have several aspects directly below. The quality of rubber sealing rings is not up to standard. At present, a wide range of hydraulic seals are made of silicone raw materials, but the quality of hydraulic seals used by different manufacturers is also different. If the raw materials of hydraulic seals are hard or the quality of silicone keys is not good, the cracking difficulties will occur after the machinery and equipment have been running for a period of time. If such problems often occur, the cost of related spare parts will be increased.

When installing the rubber sealing ring, it is necessary to prevent forced installation and cannot be knocked in with a hammer. Use a utility tool to press the hydraulic sealing ring against the hole edge first, and the product models to be disassembled and replaced should be consistent. The deformation of rubber sealing ring is divided into recoverable deformation and non-recoverable deformation. Recoverable deformation means slight deformation, such as small amplitude twisting, twisting, curling, non-recoverable deformation means serious deformation, such as sealing ring crease, fracture, etc. After the slightly deformed rubber seal ring recovers its shape, it can be used normally without loss of sealing function, while the severely deformed rubber seal ring cannot be used normally even after recovering its shape. Rubber sealing ring stored for a long time, will produce a slight deformation of the phenomenon, how to restore the deformation of rubber sealing ring. 1. Take out the deformed rubber sealing ring, heat a pot of water quickly, and pour it into the container. 2. After pouring boiling water into the container, soak the rubber sealing ring in boiling water. 3. After soaking for a few minutes, take out the rubber sealing ring and pull it by hand. 4. After pulling, it is OK to restore the elasticity, so that the rubber sealing ring will return to its original shape. When it comes to rubber sealing rings, many people are all an impression, that is, they think that its characteristics are O-shaped and round. There is nothing wrong with it. This is indeed one of its major characteristics. Many people think that the operation method of this product is very simple, but the objective fact is that if it is not applied in time, it is likely to cause early damage and damage. Therefore, we must master more things to pay attention to during installation, only then can all normal applications prevent problems. When installing and applying rubber sealing rings, we should pay attention not to apply too much. The service life of general commodities is 3000~5000h h. After exceeding the service life, we should immediately replace the new sealing ring. When replacing the new sealing ring, we should also carefully consider its service performance. Silicone keys should be established without defects such as small round holes, small meat spots, gaps and concave grooves and have sufficient plasticity before everything can be delivered for normal use. When replacing, it is necessary to strictly check the excavation of the sealing ring groove, remove the dirt inside, polish the pipe drainage ditch, and prevent the lip from being reversed or damaged. If the lip is damaged by more than 50μm, it may lead to prominent oil leakage.

Product characteristics of rubber feet. 1, with a reversible deformation of high elastic polymer material, elastic at room temperature, under the action of a small external force can produce a larger deformation, after removing the external force can be restored to its original state, rubber is a completely amorphous polymer, its glass transition temperature (Tg) is low, the molecular weight is often large, more than hundreds of thousands. 2. Rubber is a hot-soluble thermosetting elastomer, while plastic is hot-soluble and cold-cured. Due to the different types of sulfides, rubber has a considerable difference in the temperature range of its molding and curing. It can even be affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber finished products need to be appropriately adjusted at any time. If not, the quality of products may differ. Rubber foot application. It not only provides people with rubber auxiliary products for electrical products, hardware tools, furniture and furniture, medical equipment, light industry and other industrial products used in daily life. Rubber feet are beautiful in appearance, easy to use and have anti-skid, anti-collision, anti-shock, temperature resistance, noise reduction and other functions. With the improvement of people's living standards, rubber feet have been widely used in electronics, electrical appliances, furniture and furniture, hardware tools, sports equipment, metal products, musical instrument products, light industrial products and so on. O-rings are used for hydraulic presses and pneumatic control valves and various industrial equipment and components. Under the required working pressure, temperature and different liquid and vapor substances, they have sealing effects under static data or moving standards. All these people should understand this difference, but do you know how to make O-rings better and give full play to it. Another point is that when the rubber O-ring is not used, everyone should try not to open the initial package of the O-ring to prevent dust or dirt from damaging the O-ring. If the O-ring is to be stored, it should be prevented from being irradiated by the sun or placed around a high-temperature heat source (such as a heating furnace) to prevent the O-ring from embrittling too early. It should be noted that the O-ring sometimes faded during the whole storage process of the silicone key, that is, the surface of the O-ring will cause white powder, but you don't have to worry, it is not easy to cause bad harm to the O-ring.
