[Three rain valve to recommend the star product - Mechanical seal] Description: When you install one, be very careful to avoid the resulting installation misalignment (1), the gland should be coupling alignment after H75 -45 mechanical seal, bolts should be uniform on the branch, to prevent the end face deflection gland with feeler points, the error is not greater than 0.05 mm. (2) Check the gland and the shaft or sleeve diameter with the gap (ie, concentricity), four weeks should be uniform, with a feeler points tolerance is not greater than 0.01 mm. 2, according to the provisions compression spring, does not allow too large or too small phenomenon, requiring error 2.00 mm. Excessive face pressure to increase and accelerate wear face. Too small will cause less than the pressure seal and can not play. 3. After installation H75-80 mechanical seal ring, the ring is pressed against the rear springs should be able to automatically bounce back. [Three rain valve to recommend the star product - Mechanical seal] Introduction: Stretch loading mechanism and secondary seal is metallic bellows mechanical seal we called metal bellows seal. In light seal 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." HBM1 type mechanical seals according to DIN24960 standards for single face, balanced, any spin H75-65 mechanical seal to seal metal bellows type, ring O-ring, flexible graphite ring afford compensation, so the bellows move without resistance, suitable for high temperature, high-viscosity media. Vice friction materials and auxiliary materials should be selected according to the actual conditions. Scope: Sealed Medium: general corrosive liquid oil, acid and alkali. Sealed chamber: When the bellows under external pressure ≤2.5Mpa when pressed by ≤1.5Mpa bellows sealed chamber temperature: -20 ℃ ~ 400 ℃ line speed: ≤15m / s H75-65 mechanical seal | Mechanical seal selection Three rain (certified) | Zunyi mechanical seal is provided by three rain Valve Co., Ltd. of Tianjin. 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.
