Hydraulic rubber seals can be so widely used mainly because of its performance. Therefore, in different aspects, different fields will have certain application

To understand the specific benefits of hydraulic rubber seals.

1, leakage is very small and good compatibility

Small leakage and good compatibility is a particularly important advantage of hydraulic rubber seals. If you want to seal well, you need minimal leakage, and hydraulic rubber seals just meet this point. It is also very important that as the pressure of the hydraulic oil increases, the air tightness of the hydraulic rubber seal will also increase. Whether it is under high temperature or high pressure, it can keep its sealing performance well and will not be affected by any other. The good compatibility is mainly because in the hydraulic rubber seal compared with the general performance of the seal, there will be no swelling or dissolution of the phenomenon that makes the seal become fragile, and finally even disappear. These conditions for hydraulic rubber seals are not happening, do not need to worry too much.

2, small friction resistance

Frictional resistance is also a small hydraulic one of rubber seal has an advantage, because of low friction resistance can be good for the coefficient of friction under a relatively stable state, which is needed for hydraulic equipment under low pressure condition of a sealed condition, if the friction resistance is too large for hydraulic rubber seals can produce a lot of inconvenience.

3. Long available time

Because the coefficient of friction is in a relatively stable state, hydraulic rubber seals will be more wear-resistant, pressure-resistant, and more able to resist different harsh environments, which makes the available time of hydraulic rubber seals become very long.

4. Good quality and cheap price

Hydraulic rubber seal is cheap and fine, compared with other kinds of seals, its price is one of the relatively cheaper, but also is very convenient when use, together with some advantages mentioned above, hydraulic seal rubber seal is a high performance, affordable to describe it is very appropriate, it is not only the production process is very simple, And yields and returns are good. Therefore, this is also one of the reasons why it is popular, because most people have a high favorable impression on the things with good quality and low price.

Different mechanical equipment and working environment, the requirements of hydraulic rubber seals are different. When we select hydraulic rubber seals, the first three factors to consider are temperature, pressure and medium.

Temperature: most hydraulic seal systems have requirements for temperature, just high or low requirements. Generally speaking, the high temperature resistance of fluorine rubber and silicone rubber is more outstanding, the higher is fluorine silicone rubber, can be resistant to 300℃. Low temperature resistance is also part of our consideration, and the material we often use is NBR.

Pressure: Rubber manufacturer pressure is also unavoidable in the sealing system. Generally speaking, low and medium pressure rubber or PU seal will not be too big a problem. But we should consider the problem of impact pressure. For example, when construction machinery is started and closed, its impact pressure is much greater than the normal working pressure, so it often chooses the impact and squeeze resistance HBY or SPGW, which can withstand pressure up to 70MPA, as the main seal. PTFE combination seals are also a common option.
