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.
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.
Hello!According to the situation you mentioned or according to the sealing ring group environment, and seal material, of course, different work environment will choose different materials, but the current domestic product life is very short, it is of poor quality,. In the case of ensuring the quality of hydraulic oil, there is no bias load of the cylinder, and the imported products with good quality can be used for 15000 hours. If the quality is poor, it may not be possible for 2000 hours. That is why the import quality is several times higher than the domestic price! Thank you
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?
