Which aspects endanger the application of sealing rings?

The Sealing ring has the advantages of good Sealing characteristics, simple structure, cost-effective engineering cost, convenient installation and strong acceptability. Below is a summary of the many layers that the sealing ring should pay attention to!

1. Sealing ring material and pressure:

The pressure of the sealing ring material is also very sensitive. There are big differences in the working pressure that the sealing ring made of different raw materials and different types of sealing rings can accept. Therefore, there are pressure test, acid and alkali resistance in the sealing ring products. , High temperature resistance. In the case of skeleton seals, the accepted pressure is small, and if it exceeds its acceptable operating scale, it will not always lead to leakage and reduce the life of the Seal.

The existence of the sealing ring is essentially in order to maintain the machinery and equipment and maintain all the normal work of the machinery and equipment. For example, in the hydraulic cylinder, the sealing ring can avoid mutual leakage and prevent external residues from entering the machinery and equipment. The environmental pollution of oil and the contradiction between the components of machinery and equipment increase the service life of machinery and equipment and reduce the problems in work.

The pros and cons of a piece of machinery and equipment sealing equipment have increasingly become the key overall goal to identify the role of machinery and equipment. With the progress of contemporary specialization, old and crude sealing methods will be gradually selected. The location occupied by sealing equipment as a supplement to industrial equipment will become more and more critical.

2. Sealing ring material and mechanical movement rate:

The habitual working ability of the sealing ring material to the mechanical movement rate is also different. When the rotation speed of the mechanical equipment is high, the sealing ring of the raw material will usually be ineffective and cause leakage.

3. Sealing ring material and operating temperature:

The effect of temperature-related sealing materials is very harmful, and it cannot be too high or too low. If the temperature is too high, the strength and tensile strength of the sealing ring will be reduced, and if the temperature is too low, the sealing ring will become brittle. Therefore, each sealing material often has its own habitual lower and higher temperature. Nowadays, most of the sealing ring materials are mostly mixed raw materials, so the temperature should be controlled more accurately.

4. The compatibility between the sealing ring material and the material at work:

It is a very important basis to select the sealing material according to the sealing material, because the sealing ring will come into immediate contact with the sealing material. If there is no good compatibility between them, it will not always destroy the sealing ring and also pollute the environment. sexual substances. The raw material of the sealing ring should not be corroded and damaged by the sealing material, and a series of conditions such as exothermic reaction will occur.
