Valve Oil Seal

Q:What's the function of the sealing ring?: Mechanical seal work should pay attention to the problem1, installation notesA, take great care to avoid installation errors in installation(1) to tighten the gland should be aligned in the coupling bolts should be uniform, to prevent the end cap oblique, with feeler check, the error is less than 0.05 mm.(2) clearance check the gland and the shaft or shaft diameter (i.e. concentricity), around to evenly, not more than 0.01 mm check with the feeler the tolerance.B, spring compression amount should be carried out according to regulations, not allowed to have too large or too small phenomenon, requiring 2 millimeters of error. Excessive assembly increases the face to face pressure, and the other speeds end wear. Too little will cause less pressure than sealing.C, the ring should be installed to ensure flexible movement on the axis, the moving ring pressure to the spring, it should automatically bounce back.

Q:What type of sealing roller bearings.: The seal can be divided into two categories with seal and seal with roller bearings. The so-called bearing comes with sealing, that is, the bearing itself is made into a sealing device. Such as bearings, dust cover, sealing ring and so on. The utility model has the advantages of small space occupation, convenient installation and disassembly and low cost.

Q:Design of sealing ring, groove and bottom fillet of sealing ring: Hello, Lei Xin sealing ring, the outer corner of the groove of the sealing ring is designed to prevent the scratch of the O ring assembly. It generally uses a smaller rounded radius, that is, r=0.1~0.2mm. This avoids the formation of a sharp edge, the O ring does not dare to squeeze out the gap, and can make the retainer stable

Q:Looked at some of your questions about the sealing ring, I think you are a master in this fieldHave a question to ask about the sealing ring on the mechanical supporting industry inside, there is a reasonable use of time (under normal working conditions), also found a lot of norms, did not seem to have the answer I want. I wonder if you know any specifications or official statements.: To answer this question, you generally, the quality of Taiwan's sealing ring must be very good, in a normal working pressure, the temperature is appropriate, a service life of the sealing ring may be decades, there may be hundreds of years, and so you say, as long as the machine is not a problem, then the sealing ring is not removed, you can continue to use, as long as the machine is out of the question, to open the maintenance, so the sealing ring will need to be replaced. So why do those machines manufacturers buy a lot of seals?

Q:What kind of seal is the dust sealing ring?: Material features of dust ringNow most of the dust ring is formed by rubber material processing, the material dust ring is the biggest characteristic of dry friction, hence the need for the rubber material has excellent wear resistance, and low compression permanent deformation. In recent years, dust and other materials seal slowly up, such as PTFE and O ring combination, its sealing effect is very ideal, but you can use a long time, now the place is more and more.

Q:What is mechanical seal?Single mechanical seal? Double mechanical seal? What's the shaft seal?: So in today's world, mechanical seal is the most important shaft seal in these equipment. The mechanical seal is also called the seal, in the relevant national standard is defined as: "by at least a pair of end faces perpendicular to the axis of rotation of the fluid pressure and the elasticity of compensation organizations (or magnetic) device and the role of the coordination of auxiliary seals to keep up with the relative sliding to prevent fluid leakage. "

Q:You want to ask knowledgeable friends. I want to do at home produced small seal factory. The former is to buy it do seal butterfly valve. Now they want to engage in their own ring. Do not know what equipment and capital equipment. Then buy new and used funds is how much. Is the production of multi-level sealing ring and PTFE. What materials should I indebted forever: Rubber and PTFE are two different production processes. The main equipment for rubber seals is vulcanizing machine, mixer, cutting machine, testing equipment and so on, and the investment is still very high.

Q:Can hydraulic oil be used in the mechanical seal room?: 1. It has certain mechanical and physical properties, such as tensile strength, tensile strength and elongation;2, a certain flexibility, hardness appropriate, and compression permanent deformation is small;3, and the working medium to adapt to, not easy to produce swelling, decomposition and hardening;4, wear-resistant, has a certain resistance to tearing;5, with high temperature, low temperature aging performance.

Q:What's the difference between the oil seal and the seal?: The placement of the skeleton has strict requirements, and the standard and specifications of the products are different. Of course, the prices are more expensive than those made in China

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.
