Which aspects do we need to pay attention to when selecting sealing corrosion-resistant O-ring materials?

The role of sealing corrosion resistant O-ring is usually sealed, it can seal a wide variety of substances, most of which are dominated by raw material oil, so it can also play the role of dust and slag separation pool under the premise of sealing, its characteristics directly affect the performance of machinery and equipment, thus affecting its characteristics of the key element is its material. Select materials should pay attention to which points, to give you a brief introduction.

1. Movement rate of mechanical equipment

Different sealing ring material will have different adaptability to the speed of mechanical equipment. At this stage, there are many raw materials for sealing rings, some of which are general raw materials, difficult to adapt to fast mechanical equipment operation, so if it is used for fast mechanical equipment operation site sealing rings, the material used should be high grade, so as to meet the requirements of high-speed operation.

2. Working pressure

Sealing ring materials for the work of the pressure is not the same, and raw materials are particularly sensitive to the pressure. The selection of materials is not the same, can withstand the pressure size is not the same, can also be based on the material to seal to select raw materials, such as material is raw material oil, they bear relatively large pressure, if the use of poor bearing capacity of raw materials, will cause the bearing capacity of raw materials beyond their own can bear the category, the service life of the sealing ring will decline, so to choose high bearing capacity of material.

3. Material compatibility

This is very important, in some cases, the sealing ring material and the sealed material need to carry out direct contact, if the two can not be dissolved, it may cause one of the material into the other party, cause system environmental pollution, or cause damage to the sealing ring, material leakage. In addition, the selection of sealing ring material can not be corroded by substances, nor can it produce chemical changes with substances, so in the selection of data should pay particular attention to this point.

4. Ambient temperature

In the selection of tight sealing ring materials, we should also consider the environmental temperature. The category of high temperature resistance of different materials is not the same. For some materials, the application site temperature is too high or too low is not conducive to play a role. In addition, the temperature adaptability of the material itself is very limited. Low temperature will also lead to the sealing ring becoming brittle. Too high temperature will also lead to the reduction of the degree and strength of the sealing ring.

When selecting sealing corrosion-resistant O-ring materials, it is necessary to take full consideration, including movement speed and working pressure, as well as material compatibility and environmental temperature. If you choose a certain degree of difficulty to consult the company's professionals, let them help you choose suitable materials.
