Preliminary Work For Installing O-rings

The open piston seals is mainly used in the automobile air pump industry. The O-ring made of modified polytetrafluoroethylene is used in rotating mechanical equipment, and has good water resistance, high temperature resistance and abrasion resistance.

Preparatory work for installing O rings before mechanical operation:

1. First, check whether the specifications of the PTFE O-ring seal are correct;

2. Check whether each part of the sealing machine is operating normally, and whether the gasket is not scratched to avoid leakage;

3. Check whether the sealing lead-in angle is processed according to the engineering drawing, and secondly whether the sharp edge is chamfered or rounded;

4. Check whether the sealing element and the sealing ring have been evenly coated with lubricating oil or lubricating fluid to ensure the elasticity of the O-ring seal medium;

5. In addition, O-rings cannot use lubricating oil containing solid additives;
