??We have to understand the hydraulic seal

??Hydraulic seal role: to prevent fluid or solid particles between the surface and prevent leakage from adjacent binding material or foreign matter such as dust and water intrusion and other parts inside the machine equipment parts.

??Hydraulic seals, once lost the role of dust, impurities are brought into the internal cylinder, and the cylinder wall will hydraulic rod outer wall caused by wear and tear, after which, if badly worn seals will produce a cutting action, shorten the service life of hydraulic seals. Therefore, in a dusty environment, when damaged hydraulic seals, the need for timely replacement.

??Features hydraulic seal: a very small amount leaked and service life, the amount of leaked hydraulic seal is extremely small, have a good seal, and with the increased pressure of the hydraulic oil and active role in the progress of its sealing, even at low pressure and low temperature unruly under task environment, the amount of leaked hydraulic seal and no significant increase. Hydraulic seal should have good elasticity, heat resistance, cold resistance, pressure resistance, wear resistance and mechanical strength for sure, and the use of long life.

??Influence of hydraulic seal are: First, the impact pressure is a hydraulic seal member important cause of quality, high and low pressure, the pressure variation cycle length, has a great influence on the seal is broken (e.g. extrusion). The higher the pressure, the greater the influence of other factors on the performance of the seal gap gap such as temperature, velocity and material of the sealing member, the piston and the cylinder between the piston and the cylinder head. Hydraulic seals the influence of surface friction, surface roughness values ??of the surface characteristics common to define RA, RA is the arithmetic average deviation from the center line of the surface shape of the absolute value. These values ??but not sufficient to represent the effect of surface conditions on the hydraulic seal, since even under the same roughness, different surface shapes of features may result in different levels of the sealing member seals wear.

??How to buy hydraulic seals? Now we can evaluate the actual manual work environment determines the hardness of the material. Also refer to the test sample data, according to the data redemption hydraulic seals.
