[Three rain valve to recommend the star product - Mechanical seal] Introduction: Reason mechanical seal mechanical seal failure after failure in general are known to be people from the leak appeared abnormal, abnormal wear, abnormal torque phenomenon . Cause of the fault roughly the following four aspects: 1, the mechanical seal design selection wrong; 2, poor quality mechanical seals; 3, use or installation of mechanical seals mainly the precision of the machine itself; 4, the machine running the operating error . [Three rain valve to recommend the star product - Mechanical seal] Introduction: HU21 mechanical seal, the main face of various pipeline pumps, sewage pump, water pump, submersible pumps and other conditions very bad media, the installation dimensions short, the balance factor, can replace a variety of light mechanical seals: 502,2100 Crane, Burgmann MG1 112-90 mechanical seal, made 109112-80 mechanical seal, BIA, FBD and other mechanical seal, which led the drive to rely on rubber cards, fork drive, effectively avoiding the failure rate and aging of rubber bellows. Scope: Sealed Medium: Oil, water, and other general corrosive liquids. Seal chamber pressure: ≤0.6Mpa sealed chamber temperature: -40 ℃ ~ 120 ℃ line speed: ≤15m / s 112-80 mechanical seal mechanical seal manufacturers _ selected three rain (certified) _ Zhaotong mechanical seal pumps from Tianjin three rain Valve Co., Ltd. offers.
