Sealing with pressure is a common sealing technology, which has been widely used in many fields. Whether in the construction, engineering, manufacturing or automotive industries, pressure sealing is the key to ensuring effective sealing. In this article, I will introduce the principle of pressure plugging in detail.

The principle of sealing with pressure is based on the plasticity and elasticity of the sealing material, as well as the external pressure applied. By applying pressure, the sealing material fills the tiny gaps between the sealing surfaces, creating a tight seal. This tight seal can effectively prevent the leakage of liquid, gas or solid particles, ensuring the stable operation of the system.

The application of pressure plugging is very wide. In the construction and engineering field, pressure sealing is often used in pipeline connection, water blocking treatment and sealing structures. In the manufacturing industry, pressure sealing is often used in the sealing of mechanical equipment, hydraulic systems and pneumatic systems. In the automotive industry, pressure sealing is widely used in engine sealing, transmission system sealing and body sealing.

The sealing effect with pressure sealing mainly depends on the choice of sealing material and the pressure applied. The suitable sealing material should have good plasticity and elasticity, and be able to fill the small defects on the sealing surface. At the same time, the sealing material should also have the characteristics of high temperature resistance, corrosion resistance and pressure resistance to adapt to the sealing needs under different environmental conditions.

In addition, the applied pressure is also a key factor in the sealing effect with pressure sealing. The appropriate pressure can make the sealing material better contact with the sealing surface to ensure the tightness of the seal. Too low a pressure may result in a loose seal, resulting in leakage. Excessive pressure may lead to damage or deformation of the sealing material, which will affect the sealing effect and the normal operation of the equipment.

When evaluating the sealing effect with a pressure plug, the following aspects are generally considered: 640048a0d8d7a.jpg

1. Sealing performance: Sealing performance is one of the key indicators to evaluate the sealing effect with pressure. It reflects the extent to which the sealing material prevents the leakage of liquid, gas or solid particles. Through the testing and evaluation of sealing performance, the effect of sealing technology with pressure in practical application can be evaluated.

2. Corrosion resistance: The sealing material with pressure should have a certain corrosion resistance and can maintain the sealing effect under different environmental conditions. For the sealing of corrosive media, the sealing material should have good corrosion resistance and can prevent the erosion of the sealing material by the medium, so as to ensure the long-term reliability of the seal.

3. High temperature resistance: The use of sealing materials with pressure is also very common in some high temperature environments. Therefore, the sealing material should have good high temperature resistance and be able to maintain the sealing effect and mechanical properties under high temperature conditions. This is essential for the normal operation of some high-temperature processes and equipment.

4. Life and reliability: The life and reliability of sealing technology with pressure is another important consideration. The sealing material should have a long service life and be able to maintain a good sealing effect in long-term use. At the same time, the reliability of sealing materials should also be fully verified and evaluated to ensure reliability under various working conditions.

In general, the sealing effect of a pressure seal depends on the combined action of several factors. Proper selection of sealing materials, reasonable application of pressure and good sealing performance, corrosion resistance, high temperature resistance and reliability are the keys to ensure the sealing effect with pressure. On the basis of comprehensive consideration of these factors
