Related Introduction
Mechanical seal requirements for machine accuracy (take mechanical seals for pumps as an example)
(1) The maximum 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 and the sealing end cover is no more than 0.04～0.06MM.
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.
(3) The mechanical seal is driven by a parallel spring. The spring can be divided into left and right rotation, which must be selected according to the rotation direction of the shaft.
