The function and significance of hydraulic seals
Update:2016-05-26
In the hydraulic system and as the system, the seals device is used to prevent the leakage of the working medium and the invasion of the external dust and foreign matter. One of the components of the sealing effect, that is the Seals.
External leakage will cause the waste of the working medium, pollute the machine and the environment, and even cause the failure of mechanical operation and equipment accident.
Internal leakage will cause a sharp drop in volumetric efficiency of hydraulic system, can not reach the required working pressure, and even can not be carried out.
Tiny dust particles in the system can cause or aggravate the wear of hydraulic components, which will lead to leakage.
Therefore, the seal and seal device is an important part of the hydraulic equipment. Reliability and service life of the hydraulic system is an important indicator of the quality of the hydraulic system.
In addition to sealing the outer space, it is the use of the seal, so that the gap between two adjacent surfaces of the coupling between the control minimum gap to be sealed through the liquid below.
In the contact seal, the seal pressed into self-seal and self-tight seal ( lip seal).
