[Three rain valve to recommend the star product - Mechanical seal] Introduction: mechanical seal from the end face of at least one axis of rotation perpendicular to the fluid pressure is maintained at a stretch and compensation mechanism (or magnetic) role and assist with the seal affixed combined relative sliding constitute means to prevent fluid leakage H7N-32 mechanical seal, commonly used in pumps, compressors, reactor with an agitator, etc. rotary fluid machinery, but also for a gear box, valves, rotary joint, stern shaft seal. Therefore, the mechanical seal is a universal shaft sealing device. Mechanical seal Structure: Single seal; unbalanced; conical spring; fixed rotation; the scope of the mechanical seal complies with EN12756 (DIN24960) standard, simple structure, widely used, and good reliability. Suitable for clean water pumps, sewage pumps, submersible pumps and chemical flow pumps. Run Specifications: 6 ~ 80mm Temperature: -20 ℃ ~ + 180 ℃ Pressure: ≤1.0MPa line speed: ≤15m / s Axial movement: ± 1.0mm Medium: used in water, oil, organic solvents and other corrosive medium. [Three rain valve to recommend the star product - Mechanical seal] Description: hollow metal O-ring: good elasticity, compression force is small, there are self-tightening effect, can choose a variety of metal materials, resulting in low temperature, high temperature and strong corrosive media can adapt. Graphite plate ring: in people's minds, graphite is a brittle material, lack of flexibility and toughness H7N-22 mechanical seal, but after H7N-33 graphite mechanical seal special treatment, but it is soft and good elasticity. Thus, the graphite heat resistance and chemical stability mechanical seal, it can be displayed in the gasket material; and this gasket compression force is small, abnormal superior sealing effect. This can be made with graphite, with metal band with the composition of high performance wound gaskets. Graphite sheet gaskets and spiral wound gasket graphite ---- The emergence of high-temperature corrosion-resistant sealing a major breakthrough. Such washers, has a large number of overseas production and use of mechanical seal H7N-20 |. Mechanical seal selected three rain (certified) | Ordos mechanical seal is provided by three rain Valve Co., Ltd. of Tianjin. Valve Co., Ltd.
