[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: The main reason of seal failure: overheating due to the sealing surface will produce heat, so the rubber ring temperature should be below the design specifications. Viton and PTFE use temperature of 216 ℃, NBR's temperature is 162 ℃, although they can withstand higher temperatures 103-45 mechanical seal, but the sealing surface of the heat generated by high 103- 55 mechanical seal, it is dangerous to continue vulcanized rubber ring and eventually loses its elasticity and leak. (Considering the cold crisp cold zone) but also because of the heat caused by the mechanical seal between the sealing surface crystallization medium, such as knot carbon, causing the sliding member is stuck and the sealing surface is condensed. And some of the polymer due to overheating and coking, lose some fluid lubrication due to overheating or even a flash fire. Superheated medium except for status change, it will aggravate the corrosion rate. Deformation caused by metal parts 103-25 mechanical seal, crack alloy surface, as well as some cracks in the coating, designed balanced mechanical seals should be used to reduce the specific pressure to prevent overheating. 103-30 mechanical seal | Ezhou mechanical seal | 103 GB mechanical seal provided by the election of three rain Valve Co., Ltd.
