Mechanical seals are one of the basic mechanical components with a more complicated structure. They are the key components of various mechanical seal pumps, reaction synthesis kettles, turbo compressors, submersible motors and other equipment. However, in order to ensure their efficiency, they need to be detailed Understand the installation and use requirements of its accessories, so as to ensure the smooth use of the equipment.
  1. The requirements of mechanical seals on machine accuracy (take mechanical seals for pumps as an example)
  (1) The radial runout tolerance of the shaft (or sleeve) where the mechanical seal is installed does not exceed 0.04~0.06MM.
  (2) The axial movement of the rotor does not exceed 0.3MM.
  (3) The runout tolerance of the positioning end facing the shaft (or sleeve) surface of the sealing cavity combined with the sealing end cover is not more than 0.04~0.06MM.
  2. Confirmation of seals
  (1) Confirm whether the installed seal is consistent with the required model.
   (2) Check carefully with the final assembly drawing before installation, and check whether the number of parts is complete.
