Installation and storage of seals
Three items should be paid attention to when installing seals: 1. Do not damage the sealing surface or sealing line on the surface of the seal. The sealing function of the flat seal depends on the upper and lower end faces; the sealing function of the hydraulic seal depends on the lip line associated with the hole or shaft. , These parts are composed of temperature-resistant, corrosion-resistant, aging-resistant graphite, rubber and plastic, fiber, which are both soft and resilient, and mechanical seals that are easily damaged. Special maintenance and care are given. Once damaged, it will often leave a great danger to the sealing part; 2. Do not force the installation. Some seals are placed in the grooved stuffing box. At this time, a tight fitting device is required, and the construction should not be rough. The original prefabricated structure of the seal will be destroyed by forceful installation, which is like breaking the prefabricated concrete and filling it into the required parts, which will inevitably lead to disasters. The installation of this type of seal must be very careful and careful, and the insertion must be carried out step by step; 3. The installation should be balanced and symmetrical, and the seal should be placed in the position just close to the effective sealing surface (or lip line). After the system is registered and used, further investigation and aftermath of the tightening seals are required to avoid failure caused by micro-leakage due to changes in working conditions (such as pressurization) during system operation. The seals should be properly stored when they are not in use temporarily. 1. Anti-aging, light-proof, moisture-proof, placed flat, away from cold and heat sources; 2. Do not apply pressure to keep the seals in a natural loose state, and do not apply external force to change their physical shape; 3. Classify (same shape, different raw materials, used parts, applicable standards, purchase date, etc.)
