[Three rain valve to recommend the star product - Mechanical seal] Description: Single seal / Unbalanced / rotation / comply with EN12756 (DIN24960) standard widely used in the series H7N-95 mechanical seal, interchangeability, non-tight sealing ring embedding, easy to replace. Take the child to push the ring gear jammed by mechanical seal, to prevent the spring off. Static ring can limit H7N-85 mechanical seal, spring travel restricted H7N-65 machine closures, avoiding excessive wear carbon ring. Mechanical seals are precision, one of the basic elements of mechanical structure is more complex, and is a key component of various pumps, reaction synthesis reactor, turbine compressors, submersible motors and other equipment. Sealing performance and service life depends on many factors, such as the accuracy of selection, the machine, the correct installation and so on.
