Mechanical seals are one of the mechanical basic components with complex structures, and are key components of various mechanical seals, pumps, reaction synthesis kettles, turbo compressors, submersible motors and other equipment. However, in order to ensure their use efficiency, 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 for machine accuracy (take mechanical seals for pumps as an example)

(1) The radial runout tolerance of the shaft (or shaft sleeve) where the mechanical seal is installed should 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 of the sealing cavity combined with the sealing end cover facing the surface of the shaft (or shaft sleeve) 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) Before installation, carefully check with the general assembly drawing to see if the number of parts is complete.

(3) For mechanical seals driven by parallel coil springs, the springs are divided into left and right rotations, which must be selected according to the rotation direction of the rotating shaft.

The above is an introduction to the installation and use requirements of the mechanical seal. According to its introduction, we can install it more conveniently and operate the equipment reasonably, so as to effectively meet the use requirements of the equipment.
