Abstract

The invention discloses a tool for detecting and adjusting a magnetic sealing apparatus, and an installation method. The magnetic sealing apparatus comprises a moving ring, a static ring, an inner O-shaped ring and an outer O-shaped ring, wherein the sealing end surface of the moving ring and the static ring are closely attached through a magnetic force to form magnetic sealing. The tool comprises a gauge frame shaft extending to a gear shaft, a positioning pressure plate connected with the gauge frame shaft for positioning the gauge frame shaft at an axle center position, a dial gauge used for measuring flatness of the magnetic sealing apparatus, a fine tuning screw used for adjusting the flatness of the magnetic sealing apparatus according to a flatness value measured by the dial gauge, and an adjustment frame gauge beam vertically arranged on the gauge frame shaft for installing the dial gauge and the fine tuning screw. According to the invention, through improving a conventional assembling technical method, the problem of a final assembling result of the moving ring and the static ring, i.e., the whole magnetic sealing apparatus can be solved, the detection and adjustment process can be completely synchronously, and the leakage failure rate of the magnetic sealing apparatus is obviously reduced.

Description

technical field [0001] The invention relates to the field of shaft seal detection, in particular to a tool for detecting and adjusting a magnetic sealing device. In addition, the present invention also relates to a method for installing the above tool for detecting and adjusting the magnetic sealing device. Background technique [0002] The magnetic sealing device is an axial positioning structure, which is divided into two types: dynamic sealing and static sealing. Magnetic force is the main dynamic sealing factor to close the sealing end face, but it cannot absorb the axial vibration of the cavity. For dynamic sealing, due to relative motion and vibration Appropriate and uniform end face specific pressure is an important condition to ensure the long-term safe operation of the mechanical seal. When assembling the traditional tooling used for testing the magnetic sealing device, press the static ring into the casing cover with the tooling (the back of the static ring faces ...
