For the relevant relationship between the size of the slurry pump and the precision of the slurry pump, the skill requirements are introduced:
Check whether the dimensional accuracy, accuracy and interrelationship of the relevant parts between the slurry pump and the mechanical seal device meet the skill needs. It mainly includes the following aspects:
At the top of the list, the radial runout tolerance of the shaft (or shaft sleeve) at the mechanical seal part of the device, and the surface finish and outer diameter of the shaft (or shaft sleeve) are in service.
Second, the allowable straightness of the contact positioning end face of the sealing cavity and the gland to the centerline of the shaft (or shaft sleeve).
Third, the chamfer and finish of the end of the shaft (or shaft sleeve) of the moving ring seal ring of the device and the end structure of the shell hole of the mechanical seal of the device.
Fourth, the axial displacement of the rotating shaft of the mechanical seal.
