[Three rain valve to recommend the star product - Mechanical seal] mechanical seal (mechanical seal) is defined by at least one axis of rotation perpendicular to the face of the compensation mechanism under fluid pressure and elasticity (or magnetic) role and secondary seal fluid leakage with holding means affixed under the combined constituted prevent relative sliding. Elastic loading mechanism and secondary seal is metallic bellows mechanical seal we called metal bellows seal. In light seal 103-80 mechanical seal, as well as the use of rubber bellows for secondary seal, rubber bellows stretch limited, generally need to be supplemented to meet the load spring stretch. "Mechanical seal" that is often referred to as "mechanical seal." [Three rain valve to recommend the star product - Mechanical seal] Introduction: Failure Analysis graphite seal ring (ring) is due to vibration 103-65 crack sealing machine transmission parts, rubber ring up big and graphite ring itself The internal stress caused 103-70 mechanical seal, while coking is caused due to high temperature, which is common in high-temperature hot oil refinery medium. Fuming sulfuric acid, nitric acid, hydrofluoric acid, sodium secondary green, aqua regia, over hydroxides erosion of graphite have several strong oxidant, corrosion effect exacerbated with increasing temperature. Usually hard ring (stationary ring) hot surface can cause severe wear of the seal ring, without the vertical pump cooling. At high temperature, high pressure, spring compression is too large, the shaft will move under the string is too large, will cause excessive wear of the sealing surface. 103-85 mechanical seal | mechanical seals manufacturer selected three rain (certified) | Liaoyuan mechanical seal is provided by Valve Co., Ltd. Tianjin three rain. Valve Co., Ltd. Tianjin three rain (www.tjsymf.com) is a leader in Tianjin, seals, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
