Xinhua Xu hydraulic seal performance characteristics of our attention
More hydraulic seals because what we demand
1, hydraulic seal materials and working media compatibility

Material seals according to seal media to choose. Between the seal material and the working medium have a good compatibility, the working medium to withstand corrosion, wear, and does not occur the precipitation, crystallization phenomena and chemical reaction media work.2, hydraulic seal materials and mechanical movement speed
Seal material ability to adapt to the mechanical movement speed is also different, when the high speed rotating machinery, ordinary material seal may fail cause leakage.
3, hydraulic seals materials and operating temperature
Effect of temperature on the seal particularly large, if the selected temperature materials can not meet the conditions, will greatly reduce the seal life.
4, hydraulic seal material and operating pressure
It is also important relationship between hydraulic seal material and the pressure, the pressure too much, will accelerate wear and tear, the pressure is too small, and the sealing effect is not ideal.
In many machines, you need to be sealed in order to work properly, if not sealed, then it may cause leakage and internal leakage, maybe even the tiny dust particles entering the system, and cause or exacerbate friction Vice abrasion of hydraulic components, further cause leakage. In severe cases, lead to mechanical failure, resulting in the loss of focusing.
Hydraulic seals mainly O-ring, round and square ring seals, etc., such a shape so that they have a simple structure, easy to manufacture, low cost, so they are dynamic sealing element widely used in the hydraulic system and static sealing element. It is because of such structural characteristics bring their performance characteristics.
1. hydraulic seal material so that the liquid inside is not easy to leak, has a good seal, even under high pressure and high temperature and other harsh working conditions, hydraulic seal leakage and no significant increase.
