Description

Technical Field

[0001] The present invention relates to the technical field of balancing disc processing, and in particular to a balancing disc forming device and a use method thereof. Background Art

[0002] The balancing disc is a disc placed behind the last-stage impeller (high-pressure end) of a centrifugal compressor. It uses the axial thrust generated by the pressure difference of the gas on both sides to partially offset the axial force of the rotor. The pressure on one side is almost the gas pressure in the gap between the last-stage impeller discs (high pressure), and the other side is often connected to the suction chamber of the machine, where the pressure is atmospheric pressure or intake pressure (low pressure). The pressure difference on both sides causes the rotor to be subjected to a force opposite to the axial force, the magnitude of which is determined by the force-bearing area of ​​the balancing disc. The outer circle of the balancing disc is equipped with a sealing device to maintain the pressure difference. In order to avoid the back-and-forth movement of the rotor during operation, it only balances part of the axial force, and the remaining axial force is borne by the thrust bearing. The balancing disc needs to go through multiple steps during the processing and forming process, including the need to drill holes on the disc surface of the balancing disc.

[0003] However, the existing balancing disc forming equipment cannot achieve continuous drilling when drilling holes on the surface of the balancing disc. When drilling holes at different positions, it is necessary to manually loosen the balancing disc, switch the drilling position, and finally fix it again before the drilling operation can be performed. The operation steps are cumbersome, time-consuming and labor-intensive, and the processing efficiency is low. Summary of the invention
