The general understanding of stirred tank is that there is a vessel with physical or chemical reaction. Through the structural design and parameter configuration of the vessel, the same as the performance principle of the reactor, the heating, evaporation, cooling and low-speed mixing functions required by the process can be realized.

The general understanding of stirred tank is that the stainless steel vessel with physical or chemical reaction shall be designed and parameters shall be determined according to different process conditions

The configuration, design conditions, process, inspection, manufacturing and acceptance of the stirred tank shall be in accordance with the relevant technical standards to achieve the heating, evaporation, cooling and low-speed mixing reaction functions required by the process. Pressure vessels must comply with GB150 {Steel Pressure Vessels} and atmospheric vessels must comply with NB/T47003.1-2009 {Steel Welded Atmospheric Vessels}. As a result, the pressure requirements in the reaction process have different requirements for the design of vessels, and the mechanical production strictly follows the corresponding standards for processing, testing and trial operation. According to different production processes and operating conditions, the design structure and parameters of the stirring kettle are different, that is, the structural style of the stirring kettle is different, which belongs to non-standard container equipment.

In our daily life, we can often see the stirring kettle. Its appearance has brought us great convenience. What about its shaft seal device?

1. Mechanical seal refers to two annular sealing elements, which, on the smooth and straight end face of the agitator kettle, rotate relative to each other under the action of medium pressure or spring force to form a sealing structure.

2. When the shaft rotates, it drives the spring seat, spring, spring pressing plate, moving ring and other parts to rotate together. Because of the spring force, the moving ring tightly presses on the static ring. When the shaft rotates, the moving ring rotates with the shaft, while the static ring is fixed on the seat frame and remains stationary.

The annular sealing end face of the moving ring and the stationary ring of the agitator kettle prevents the leakage of the medium. Therefore, from the structural point of view, the mechanical seal mainly changes the axial seal that is easy to leak into the end seal that is not easy to leak. It can be seen from this that the mechanical seal is selected as its shaft seal device mainly because the mechanical seal has a good sealing structure, is not easy to leak, and can promote the use, so that its performance can play a role.
