Mechanical seal rubber seals use process

   Rather than on the end face of the end face of the end face mechanical seal rubber seal usually by moving ring and static ring and the pressing element and sealing element. The moving ring and static ring composed of a pair of friction pair, a moving ring on the seal chamber fluid pressure to the end is pressed on the static ring and two ring to generate the appropriate pressure and maintain a thin layer of liquid membrane to seal. The pressing element to generate pressure, the pump in operation, also keep end fitting to ensure mechanical seal rubber seal of the seals of the media does not leak, and to prevent impurities from entering the seal, mechanical seal rubber seal sealing element dynamic seal ring and shaft clearance There is gap C B, static ring and the gland and the pump vibration, shock buffering effect. Mechanical seal in the actual operation is not an isolated components, it is with the pump parts together up and running, at the same time, through the basic principle can be seen, the mechanical seal of the normal operation conditions, such as: pump shaft of channeling the amount can not be too large, otherwise the friction faces could not form normal pressure; mechanical seal mechanical seal rubber seal of pump shaft is not too large deflection, or face pressure will not uniform and so on. Only to meet such external conditions, coupled with good mechanical seal Sealing performance, in order to achieve the desired effect.

   Mechanical seal mechanical sealing rubber seal in the use process is not able to bear the axial force of, if the existence of the axial force, the mechanical mechanical seal seal rubber seal for the impact is serious. Sometimes due to the pump axial force balancing mechanism design unreasonable and manufacturing, installation, use, resulting in axial force is not balanced out. Mechanical seal under an axial force, the operation of gland seal temperature will be higher, for polypropylene medium and at high temperatures will is melted, therefore pump start soon lose the sealing effect, static pump check sealing face leakage phenomenon occurred in continuous spray.
