Precautions for seal installation

1. Do not damage the sealing surface or sealing line on the surface of the seal. The sealing performance of the flat seal depends on the upper and lower end faces; the sealing performance of the hydraulic seal depends on the lip line associated with the hole or shaft. It is composed of special materials that are vulnerable to damage such as temperature-resistant, corrosion-resistant and aging-resistant graphite, rubber, plastic, and fiber. Therefore, special protection and care need to be given in the process of handling, installation, and storage. Once damaged, it is often It will leave a great hidden danger to the sealing part;

2. Do not install by force. Some seals are placed in the trough-shaped stuffing box. At this time, they need to be installed tightly. During construction, they should not be rough or brutal. Forcibly installed with large movements will inevitably destroy the original prefabricated structure of the seals. This is like Breaking the precast concrete and filling it in the required parts will inevitably lead to disaster. The installation of such seals must be very careful and careful, and the embedding must be carried out step by step;

3. Pay attention to balance and symmetry during installation, and place the seal at the position just close to the effective sealing surface (or lip line). After the system is put into use, it is necessary to do further observation and follow-up work of tightening the seals to prevent the collapse caused by micro-leakage due to changes in working conditions (such as pressurization) during the working process of the system.

Key points for proper storage of seals:

1. Anti-aging, light-proof, moisture-proof, placed flat, away from cold and heat sources;

2. Do not apply pressure to keep the seal in a natural relaxed state, and do not apply external force to change its physical shape;

3. Classification marking (same shape, different materials, used parts, applicable standards, purchase date, etc.).
