Rely on a pair of mechanical seals or several of the compensation mechanism in the fluid pressure and elastic (or magnetic) to keep under seal affixed to merge to achieve together with auxiliary shaft seal leakage resistance device. Advantages and disadvantages of mechanical seals for the identification of the most important difference is that the tightness, texture and life. So be sure to choose the time to buy the regular manufacturers!
 Quality mechanical seal / Mechanical seal World / mechanical seal on the pump used, it is necessary to ensure that the rotor part. For the operation of the rotor is not balanced and to have a greater part of the rotor vibration. ¢Ù radial axis maximum of not more than o. 03 ~ o. 05ram. ¢Ú wheel static balance should be looking for. ¢Û is one of the following conditions have to check the rotor balancing. Second, the components of the position tolerance. The third is concentric with the motor. Fourth, the pump is running the largest dual-vibration constant of not more than o. 06mm.

 Most technologies are of great significance in the high-quality mechanical seal / Mechanical seal the world, which has been valued by more and more people, not only because the material will cause waste of energy leakage and, more importantly, if flammable, Explosive, toxic medium leakage, can lead to catastrophic accidents. Such as the U.S. space shuttle Challenger accident, is due to mechanical rocket booster O-ring joints caused by failure.
