1. Do not damage the seal face or seal 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, both of which are both soft and rich in resilient temperature, corrosion resistance, Graphite, rubber, fiber, which is vulnerable to damage caused by the special materials, and thus need to carry, install, custody process to give special protection and care, once the damage will often leave a lot of hidden parts of the hidden dangers;

2. Prohibit Forced Installation

Some seals are placed in the groove of the stuffing box, then need to be closely installed, the construction can not be rough, brutal, very strong forced loading will destroy the original seal prefabricated structure, which is like the prefabricated concrete break After filling the required parts will inevitably lead to disaster. The installation of such seals must be very careful, careful, embedded must be carried out step by step;

3. Installation should pay attention to balance, symmetry

Place the seal in a position that is tightly attached to the effective sealing surface (or lip line). After the system is opened, the need for further observation and fastening the work of the seal after the work to prevent the system during the course of working conditions due to changes in conditions (such as pressurization) and micro-leakage caused by the collapse
