- Q: What rubber kind of rubber does the brake seal of the car use?
- The synthesis of liquid to polyethylene glycol or glycol and boric acid ester, because this "oil" may mislead him. Second, the brake should be used three yuan synthetic liquid ethylene propylene rubber (EPDM), which is resistant to chemicals because of the elementary concentration. He used EpDM production after swelling qualified, is very happy.The production of rubber products is important for the accumulation of knowledge
- Q: Mechanical, I often need to use seals, when used, suddenly do not know the specifications, size, which guy knows what manuals can be found?
- You can go to some professional forums online to download some of the electronic version of books, such as the mechanical design manual (the new software version 2008), Handbook of mechanical design software, R2.0 version of "mechanical design manual" Mechanical Industry Press, "mechanical design manual" (Third Edition) edited by Cheng Daxian chemical Industry Press
- Q: What are the seals commonly used in the industry?
- In recent years, the production and quality of rubber seal products in China have gradually entered a new stage and new period. However, only these can not satisfy the need of the development of other industries of various types of rubber seal products standardization and serialization of products, especially compared with the international advanced countries, our products in terms of product quality, or product varieties, has a considerable gap. The 100 forum focuses on the concept, seal the research content and research significance, summarizes the current situation of rubber seal, mechanical seal and packing seal technology, analysis of China's and the world advanced sealing technology in developed countries at the level of research and development ability of the new products on the gap, and our future focus on the seal the field of research and put forward some suggestions.The overall competitiveness of China's sealing industry is not strongAs we all know, in our country, the sealing industry can be regarded as the smallest industry, but the products can be used in conjunction with large industries. No matter aviation, navigation, petroleum, chemical industry, or machinery, power generation, metallurgy, mines, etc., are inseparable from the seals. In short, all organic, pump, pipe, valve places are dependent on the seal. Therefore, the industry is small, involving a wide range of faces.
- Q: What are the basic parameters of the seal on the diagram?
- Temperature: -40/+200Material: NBR/PTFE FKMMedium: hydraulic oil, flame retardant liquid, water and gas
- Q: Design of sealing ring, groove and bottom fillet of sealing ring
- The O ring seal is a typical extrusion seal. The compression ratio and stretch of the section diameter of O ring are the main contents of sealing design, which are important for sealing performance and service life. The O ring is usually installed in the sealing groove to seal. The good sealing effect of O shape seal ring depends largely on the proper matching of the size of the O ring and the groove size, forming a reasonable sealing ring, the amount of compression and the amount of tension. Sealing device design, processing, if the O ring compression is too small, it will cause leakage; too much compression will lead to O ring rubber stress relaxation caused by leakage. Similarly, excessive stretching in the work of the O ring will also accelerate aging and cause leakage. The standards of the countries all over the world have strict regulations.
- Q: What's the difference between an oil seal and a seal? Is it the same thing?
- The seal is a general term for all products that are sealed. They include O rings, oil seals, seals for piston hydraulic cylinders, dust rings, and so on,
- Q: What kind of seals are divided into?
- Seals can be divided into two categories: static seal and dynamic seal.Static seals are mainly gasket seal, sealant sealing and direct contact sealing three categories.According to the work pressure, static seal can be divided into medium and low pressure static seal and high pressure static seal. Low and medium pressure static seals are usually made of soft and wide width gasket. High pressure and static seals are made of hard material and metal gaskets with narrow width.
- Q: What are the seals? What role can they each play?
- Role of seals:All seals are used to prevent fluid or solid particles from leaking between adjacent surfaces and to prevent external impurities such as dust and moisture from invading the inside of the machine.
- Q: What are the material requirements of the valve sealing surface?
- Sealing materials should meet the requirements of sealing function. Due to the different sealing medium and different working conditions of the equipment, sealing materials are required to have different applicability. The sealing material requirements are: the material density, not easy leakage; the appropriate mechanical strength and hardness; and good elasticity, compression, permanent deformation is small; the high temperature softening, decomposition, low temperature, non hardening embrittlement; the good corrosion resistance in the long-term work of acid and alkali, oil medium, the volume of a small change in hardness, and adhesion to the metal surface; the low friction coefficient, good wear resistance; with the sealing surface with soft and full; the good anti-aging, durable; to facilitate manufacturing, price cheap, easy. Obviously, it is impossible for any material to meet the above requirements completely, but the material with excellent sealing performance can meet most of the above requirements.Rubber is the most commonly used sealing material, in addition to rubber, suitable for sealing materials as well as graphite band, PTFE and various sealants, etc. table 29.2-4 lists the classification and use of sealing materials.
- Q: What are the storage conditions for seals?
- First of all, the pressure is an important factor affecting the quality of seals, the pressure level, the length of the pressure cycle cycle, the seal damage (such as extrusion) have a great impact. The higher the pressure, the greater the influence of other factors on the performance of the seal, such as temperature, speed, the material of the seal, the clearance between the piston and the cylinder, the clearance between the piston and the cylinder head.Another is the temperature and friction, it is difficult to describe the maximum use temperature and minimum use temperature of a sealing material, because it is the result of a series of factors. The piston and piston rod have different operating temperatures, so we should choose them differently. Another is the seal product surface roughness, surface characteristics, pressure, medium, temperature, sealing materials, seals type and speed of movement, these are the factors affecting the seal.The last is surface treatment. Experience has shown that the characteristics of the surface of the cylinder piston and the piston rod have a great influence on the life of the seal. Surface characteristics are defined by the values of surface roughness RA. RA is the arithmetic mean of the shape of the surface deviating from the absolute value of the center line. However, these values do not fully indicate the effect of surface conditions on the seals, because even under the same roughness, different surface shape features can cause wear of seals to varying degrees of seal.
