What does the mechanical seal model mean?

1. Basic principles of mechanical seals

Mechanical seal is a device that uses a mechanical device to achieve relative movement of rods to form pressure between the sealing surfaces to achieve a sealed device. As a commonly used 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 face seals, corrugated seals, etc. according to their structural forms. According to their uses, they can be divided into mechanical seals for pumps, mechanical seals for compressors, and mechanical seals for mixture pumps.

3. What does the mechanical seal model mean?

1. MG1 type: represents the structural form of the mechanical seal, which is unbalanced and the spring blows to the static ring type mechanical seal. It has a simple structure and is easy to install, and is suitable for occasions with relatively common temperature and pressure conditions.

2. MG12 type: represents the structural form of the mechanical seal, which is unbalanced and spring blown to the moving ring type mechanical seal. Compared with the MG1 type, it has stronger wear resistance, corrosion resistance and drainage capacity, and is more suitable for mechanical equipment in chemical, petroleum and other environments.

3. M74 type: represents the structural form of the mechanical seal, which is unbalanced and spring blown to the moving ring type mechanical seal, similar to the MG12 type. The M74 mechanical seal has particularly good wear resistance and self-lubricating properties, and is suitable for pipeline systems in the oil refining industry, liquid ammonia, and liquid oxygen.

4. HJ92N type: Represents the structural form of mechanical seal as balanced mechanical seal, which is suitable for high-speed rotation, high temperature and high pressure pumps, compressors and other equipment. This type of mechanical seal has good self-lubricating and anti-clogging capabilities, and can greatly increase the safety margin of mechanical equipment used for sealing.

In general, choosing the most suitable model among mechanical seal models for different usage environments and processes can better ensure the sealing performance of mechanical equipment, improve production efficiency, and reduce maintenance costs.
