What are the conditions for the use of mechanical seals?
May 23, 2018

What are the conditions for the use of mechanical seals?

1. Requirements of machine seals for machine precision (taking a mechanical seal for pump as an example)

(1) The radial runout tolerance of the shaft (or sleeve) where the mechanical seal is installed should not exceed 0.04 to 0.06 mm.

(2) The rotor axial turbulence does not exceed 0.3mm.

(3) The tolerance of the positioning end of the seal cavity and the seal end cap facing the surface of the shaft (or sleeve) shall not exceed 0.04 to 0.06 mm.

2. Confirmation of mechanical seals

(1) Confirm that the installed seal is the same as the required model.

(2) Before installation, carefully check with the assembly diagram to see if the number of parts is complete.

(3) Adopt a mechanical seal with a coiled spring transmission. The spring is divided into left and right. It must be selected according to the rotation direction of the shaft.

The above two points are the basic requirements for the use of mechanical seals. It is recommended that you carefully understand the model before using the seal, and select the appropriate model type to use.
