[Three rain valve to recommend the star product - Mechanical seal] Introduction: The main reason of seal failure: the ultra-poor correct assembly tolerances, for the installation of the mechanical seal is necessary, the shaft (sleeve) must have a suitable surface roughness degree and the correct size mechanical seal, but rarely provide tolerance data 103-90 manufacturer of mechanical seal, these data are critical in terms of installation. (Rely on experience and common sense) mechanical seal dimensional accuracy and geometric tolerances must comply with the requirements of the drawings, the ultra-poor will lead to early failure of the seal. [Three rain valve to recommend the star product - Mechanical seal] Introduction: Benefits of Good Vibrations vibration rotation axis, yaw and insensitive to skew shaft seal chamber; for a wide range of mechanical seals can be used for low temperature high temperature, vacuum, pressure, different speed 103-65 mechanical seal, and a variety of corrosive media containing abrasive media such as seals. Many of today's factory "zero leak" need, packing unable to meet this requirement; simply adapt to a wide range of more arbitrary, but in the factory, frequent replacement or maintenance of the plant will cause great losses. 103-80 _ mechanical seal mechanical seal selected three rain (certified) _ Wanzhou mechanical seal is provided by Valve Co., Ltd.
