Truth: Why is the mechanical seal of the reactor sealed better than the packing?

The reaction kettle, as a typical reaction vessel, is believed to be well understood by everyone. Therefore, when stirring a plurality of materials, the lid and the cylinder are required to be sealed accordingly to achieve the required degree of vacuum of the material. To ensure the purity and production efficiency of the material, the following is a brief introduction to the advantages of the mechanical seal in the sealed form compared to the packing seal.

The sealing form of the reactor is mainly composed of packing seal and mechanical seal. The composition of the mechanical seal structure of the reactor is composed of a stationary ring (static ring) 1, a rotating ring (moving ring) 2, an elastic member 3, a spring seat 4, and a tight seal. The screw 5, the rotating ring auxiliary sealing ring 6, and the stationary ring auxiliary sealing ring 8 are composed of components, and the anti-rotating pin 7 is fixed to the gland 9 to prevent the stationary ring from rotating.
Compared with the soft packing seal, it has the following characteristics:
1. The sealing state is very reliable in the long-period operation, the leakage rate is very small, and the leakage amount is generally only 1/100 of the soft packing seal;
2, the service life in oil and water media is generally up to 1 to 2 years or more, even in chemical media can usually reach more than half a year;
3, the mechanical seal friction power consumption is small, the friction power is only 10% to 50% of the soft packing seal;

At present, Jinxitai reaction kettles are generally based on mechanical seals. Under many vacuum sealing performances, more requirements and better quality can ensure the purity of materials to a greater extent while ensuring production efficiency.
