Before the purchase of hydraulic seals

In addition to the main requirements for good sealing, the user also hopes that these types of rice flour have the following specific characteristics:

* Sealing function stability and reliability

* Long service life

* Easy to assemble

* Good compatibility with hydraulic media at high and low temperatures

* Strong resistance to mechanical damage (for example, extrusion from the gap)

* Good friction resistance

*The elastic performance is good, ensures the normal work, even if it meets the piston rod and the cavity or between the piston and the cylinder, it generates eccentricity and different degree during the operation, and the degree of expansion caused by the cylinder barrel caused by the use of pressure Can also work normally.

The main, secondary and use conditions (pressure, temperature, linear velocity, etc.) of these requirements are the key factors in selecting hydraulic seals.

Under ideal conditions, it can be reached or in some cases exceed the prescribed limit of use.

The temperature range is related to the type of mineral oil.

The limit value provided is for reference only.

Because of the variety of additions and the constant changes, we cannot make clear choices about the medium.

If necessary, we suggest to carry out the test of medium performance in the actual working conditions.

Consider the relevant working conditions, when faced with long-term work and frequent pulse pressure or other harsh operating conditions, we recommend that the maximum value of each use condition should not be applied at the same time.

If you need our application engineers’s help, we will provide you with appropriate service according to your actual working conditions.
