The use of rubber sealing ring can well prevent the leakage of lubricating oil or the intrusion of other objects, and play a good role in protecting the equipment. It is currently widely used in the electronic medical and food industries, but different uses use rubber seals The material of the pad may vary, let’s take a look at the materials of the rubber seal.
1. Fluorine rubber sealing ring: It has high temperature resistance, can be used in the environment of -30°C-+250°C, and is resistant to strong oxidants, oils, acids and alkalis. Usually used in high temperature, high vacuum and high pressure environment, suitable for oil environment. Due to various excellent properties, fluorine rubber is widely used in petroleum, chemical industry, aviation, aerospace and other departments.
2. Silicone rubber gasket: It has outstanding high and low temperature resistance performance, maintains good elasticity in the temperature range of -70°C-+260°C, and has the advantages of ozone resistance and weather aging resistance, and is suitable for thermal machinery. Gasket.
3. Nitrile rubber sealing gasket: It has excellent oil and aromatic solvent resistance, but it is not resistant to ketones, esters, and chlorinated hydrocarbons. Therefore, oil-resistant sealing products are mainly made of nitrile rubber.
4. Neoprene sealing gasket: It has good oil resistance, solvent resistance, chemical medium and other properties, but it is not resistant to aromatic oil. It is characterized by excellent resistance to weather aging and ozone aging. In production, neoprene rubber is usually used to make door and window sealing strips and diaphragms and general vacuum sealing products;
5. EPDM rubber pad: It has good temperature resistance, weather resistance and ozone aging performance, and is usually widely used in door and window sealing strips and the automobile industry.
What should be paid attention to when installing the rubber seal ring?
Rubber sealing rings are used in many mechanical equipments. Some sealing rings are used at the joint of two mechanical parts. If the rubber rings are not properly installed, it will not only affect the stability of the equipment when it is used, but also cause damage to the rubber rings. damage. Therefore, in addition to the quality of the rubber sealing ring, its installation is also very critical. In order to deepen your understanding, we have brought you some installation methods of the rubber sealing ring for later use.
1. Do not install in the wrong direction and damage the lips. The above scars on the lip may cause obvious oil leakage.
2. Prevent forced installation. It cannot be knocked in with a hammer, but a special tool should be used to press the sealing ring into the seat hole first, and then use a simple cylinder to protect the lip through the spline. Before installation, smear some grease on lip so that installation and prevent initial operation, pay attention to cleaning.
3. Prevent overdue use. The service life of the dynamic seal rubber pad is generally 5000h, and the seal ring should be replaced in time.
4. Avoid using old sealing rings. When using a new sealing ring, carefully check its surface quality, make sure there are no small holes, protrusions, cracks and grooves, etc., and have enough elasticity before use.
4. In order to prevent oil leakage due to damage, it must be operated according to the regulations. At the same time, the machine cannot be overloaded for a long time or placed in a relatively harsh environment.
