[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 carried out after the coupling alignment, Bolts should be uniform on the support to prevent deflection H75-45 end face mechanical seal gland with feeler points H75-65 mechanical seal, the error is less than 0.05 mm. (2) Check the gland and the shaft or sleeve diameter with the gap (ie, concentricity), four weeks should be uniform mechanical seal, 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 H75-90 mechanical seal ring, the ring is pressed against the rear springs should be able to automatically bounce back.
