What aspects should be paid attention to when installing seals?1

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 such as temperature-resistant, corrosion-resistant and aging-resistant graphite, rubber and plastic, and fibers that are both soft and resilient. Therefore, special protection is required during handling, installation and storage. And care, once damaged, it will often 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, the mechanical seal of the pump should not be rough or brutal. Forcibly installed with a large movement will inevitably destroy the original prefabricated structure of the seal. , which is like breaking precast concrete and filling it in the required parts, which will inevitably lead to disaster. The installation of these seals must be done with great care and care, and the insertion must be done step by step.

3. When installing, pay attention to balance and symmetry, 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.
