Precautions for seal installation
Some problems are often encountered during the installation of seals. Let's introduce three points that should be paid special attention to when installing hydraulic seals.
1. Do not damage the sealing surface or sealing line on the surface of the hydraulic seal
The sealing performance of hydraulic seals depends on the upper and lower end faces. The sealing performance of hydraulic seals depends on the lip line associated with the hole or shaft. These parts are made of soft, high temperature resistant, corrosion resistant and aging resistant materials. Graphite, rubber, plastics and fibers are made of special materials that are easily damaged. Therefore, special protection and maintenance are required during handling, installation and storage. Once damaged, it usually leaves a great hidden danger to the sealing part.
2. Do not forcibly install the seal
Some seals are placed in the grooved stuffing box. At this time, they need to be installed tightly. During installation, it shall not be rough or rough. Forced installation will destroy the original precast structure of the seal, just as it will destroy the precast concrete. Filling in the required parts will inevitably lead to disaster. The installation of this seal must be very careful and the insertion must be carried out step by step.
3. Pay attention to the balance and symmetry of seals during installation
Place the seal next to the effective sealing surface (or lip line). After opening and using the system, further observation and later maintenance of tightening seals are required to prevent system damage due to micro leakage caused by working condition change (such as pressurization) during system operation.
The above are three precautions for seal installation, which we must pay attention to during installation.
