??How true selection hydraulic seals?

??Hydraulic pressure sealing requirements, it requires a certain combination of surface finish, use of rubber sealing element, to achieve the blocking effect by local deformation of the sealing member.

??In the purchase of maintenance of hydraulic seals, most users will sample by size and color to buy, this will only increase the difficulty of procurement, and may not be able to select the appropriate product. The following procedures are recommended to improve the accuracy of purchase seals:

??1. The direction of movement of hydraulic seals - to determine the direction of movement of the location where the sealing member, such as reciprocating, rotary, or screw fixing.

??2. Hydraulic Seals emphasis - such as the decision point in the activity of the inner diameter of the rod seal or piston seal Spots in outer diameter and the like.

??3. The hydraulic seal temperature class - from the original machine instructions or consult the actual work environment assessments temperature, determine the required use of materials. Related to temperature class can be reference to the following production and user precautions.

??4. The hydraulic seal pressure ratings - Check out the data from the original description of the use of machinery, or by observing the softness and structure of the original seal infer working pressure rating, pressure class can be related to reference to the following production users attention.

??5. The hydraulic seal size - most users will be used by the old sample purchase, but the seals in use for some time, will be the temperature, pressure and wear and other factors dramatically affect its original size, press to select sample only as a reference, a better approach is to measure the location of the seal metal tank size, accuracy will be higher.

??I understand how to use hydraulic seals have to understand the density member main failure reasons and preventive measures.
