What kind of parts does the mechanical seal consist of?

The first part is the sealing end face composed of the moving ring and the static ring, which is sometimes called the friction pair.

The second part is the buffer compensation mechanism composed of the imported mechanical seal of the elastic element as the main part. Its advantage is to make the sealing end face fit closely.

The third part is the auxiliary sealing ring, which has a moving ring and a static ring in the corrosion-resistant mechanical seal.

The fourth part is the transmission mechanism that makes the moving ring twist with the shaft.

How does the mechanical seal achieve sealing: the principle of the mechanical seal is shown in the dyeing and finishing mechanical seal:

The shaft passes through the transmission seat 6 and the push ring 4 to drive the moving ring 2 to rotate, and the static ring 1 is fixed. The sealing end faces between the moving and static rings are tightly fitted by the medium pressure and spring force, preventing the leakage of the medium. After the conflicting secondary surface is worn, compensation is realized under the promotion of the spring 5. In order to prevent the medium from leaking between the moving ring and the shaft, a moving ring sealing ring 3 is installed; while the static ring sealing ring 7 prevents the medium from leaking along the static ring and the gland 8.
