Mechanical Seal Model Represents The Meaning

1. Basic principles of mechanical seals

Mechanical seals are devices that use mechanical devices to achieve relative movement of rods, so that pressure is formed between the sealing surfaces to achieve airtightness. As a common sealing method, it is widely used under high-speed rotation and high pressure.

2. Classification of mechanical seals

Mechanical seals can be divided into plane seals, end seals, wave seals, etc. according to the structural form, and can be divided into mechanical seals for pumps, mechanical seals for compressors, mechanical seals for mixing pumps, etc. according to the purpose.

3. Meaning of mechanical seal models

1. MG1 type: The structural form of the mechanical seal is an unbalanced, spring-blown static ring type mechanical seal. It has a simple structure and is easy to install. It is suitable for occasions with relatively ordinary temperature and pressure conditions.

2. MG12 type: The structural form of the mechanical seal is an unbalanced, spring-blown dynamic ring type mechanical seal. Compared with MG1 type, it has stronger wear resistance, corrosion resistance, and excretion ability, and is more suitable for mechanical equipment in chemical, petroleum and other environments.

3. M74 type: The structural form of the mechanical seal is an unbalanced, spring-blown dynamic ring type mechanical seal, which is similar to MG12 type. M74 mechanical seal has particularly good wear resistance and self-lubrication, and is suitable for pipeline systems such as oil refining industry, liquid ammonia, liquid oxygen, etc.

4. HJ92N type: The structural form of the representative mechanical seal is a balanced mechanical seal, which is suitable for high-speed rotation, high temperature and high pressure pumps and compressors and other equipment. This type of mechanical seal has good self-lubrication and anti-clogging ability, which can greatly increase the safety tolerance of mechanical equipment used for sealing.

In general, for different use environments and process flows, choosing the most suitable model in the mechanical seal model representation can better ensure the sealing performance of mechanical equipment, improve production efficiency, and reduce maintenance costs.
