Mechanical Seal Model And Specification Size Analysis

1. Basic concepts of mechanical seals

Mechanical seal is a sealing device that connects the shaft and pump body. It is mainly used to control the outflow and entry of liquid or gas. Its main function is to prevent the liquid or gas in the pump body from leaking out, ensure the flow and pressure of the liquid or gas, and ensure the normal operation of the pump.

There are many types of mechanical seals. In terms of use, they are divided into static seals and dynamic seals; in terms of structure, they are divided into single-end mechanical seals and double-end mechanical seals. In practical applications, when selecting mechanical seals, different sealing forms need to be selected according to different occasions.

2. Analysis of mechanical seal models, specifications and dimensions

The selection of the model and size of the mechanical seal is mainly determined based on the use occasion and the required sealing effect. When selecting a mechanical seal, factors such as the corrosion resistance, wear resistance, elasticity, and physical and chemical properties of the sealing medium used must be considered.

Common mechanical seal models currently on the market include: MG1, MG12, MG13, MG1s20, etc. The meaning of these models is as follows:

1. MG1: Single end mechanical seal, commonly used in water pumps.

2. MG12: Single end mechanical seal, commonly used in centrifugal compressors.

3. MG13: Double-end mechanical seal, commonly used in positive displacement pumps.

4. MG1s20: Single-end elastic packing seal, commonly used in pumps with medium temperature and high pressure.

When selecting mechanical seal specifications, factors such as its inner diameter, outer diameter, width and end seal type need to be considered. Taking the MG1 mechanical seal as an example, its inner diameter is generally 12mm-100mm, its outer diameter is 22mm-120mm, and its width is 7mm-20mm. The specific model and size can be selected according to actual use needs.

3. Summary

Mechanical seal is an essential sealing element in hydraulic transmission and mechanical transmission. Choosing the appropriate mechanical seal model and size can ensure the normal operation of the equipment and extend the service life of the equipment. When purchasing a mechanical seal, detailed consideration and comparison must be made based on the use occasion, characteristics of the medium and material, environmental conditions, etc. to ensure that the selected mechanical seal meets the actual requirements and can achieve the best sealing effect.
