Points to pay attention to when installing seals

Points to pay attention to when installing seals
1. Do not damage the sealing surface or sealing line on the surface of the seal
The sealing performance of the planar 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. These parts are composed of special materials that are both soft and resilient, such as temperature resistant, corrosion-resistant, aging resistant graphite, rubber and plastic, and fiber, which are vulnerable to damage. Therefore, special protection and care are required in the process of handling, installation, and pipe protection. Once damaged, it will often leave great hidden dangers for the sealed parts;
2. Do not install by force
Some seals are placed in the groove shaped stuffing box, which needs to be tightly fitted and installed. It is not allowed to be rough and brutal during construction. Forcible loading with a large action will inevitably destroy the original prefabricated structure of the seals, which is just like breaking the precast concrete and filling the required parts will inevitably lead to disasters. The installation of such seals must be very careful, and the insertion must be carried out step by step;
3. Pay attention to balance and symmetry during installation
Place the seal just close to the effective sealing surface (or lip line). After the system is put into operation, further observation and sealing parts tightening shall be done to prevent the collapse caused by micro leakage due to the change of working conditions (such as pressurization) during the operation of the system.
