Q:How do you determine the assembly direction of the cylinder seals?
According to the sealing direction and the pressure direction of the cylinder to determine, usually in relative direction
Q:What are static seals and dynamic seals?
For example, the hydraulic cylinder seals in the cylinder and the cylinder to seal, but the wall in the back and forth movement, which is the dynamic seal
Q:What are the cylinder seals?
Piston seal: piston seals (typically 2 U), piston guide rings (usually 1, located in the middle of the two piston seals), the piston at the end of the buffer;
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:Service life of sealing ringLooked at some of your questions about the sealing ring, I think you are a master in this field
Because they buy the sealing ring, they need to be used in conjunction with their products, a different small mechanical equipment, there will be a few or many different types of specifications of the sealing ring. So they buy a lot of them because they are used together. As long as there is oil, water, gas, basically can not be separated from the sealing ring. The effect is very large, seemingly small, but its role has even played a "national defense" role.
Q:What are the common materials of rubber seals for valves?
Different equipment and different use medium, etc., need different seals
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 a seal and a sealing strip?
Sealing strip generally refers to automobiles, trains, ships, containers, buildings, doors and windows and other seals.
Q:The seal of the front end of the cylinder and the cylinder, "O" ring, why has it been serrated for some time?,
It should be the sawtooth at the other end of the pressure chamber.
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.
