Use and maintenance of empty equipment

During the use of vacuum equipment, some failures often occur due to the influence of various factors. In order to ensure the normal operation of vacuum equipment, related parts must be repaired. Faults cannot be correctly judged and analyzed, and large-scale dismantling is common. Because some maintenance personnel are not clear about the structure and principles of vacuum equipment, they do not carefully analyze the cause of the fault, and cannot accurately judge the location of the fault. They dismantle and disassemble the machine with the wrong idea of "roughly, almost". As a result, not only the original fault was not eliminated, but also new problems appeared due to poor maintenance skills and technology. Therefore, when a machine fails, it should be detected by detection equipment. If there is no detection equipment, combined with the structure and working principle of the vacuum equipment, the most likely location of the failure can be determined through traditional fault judgment methods and means such as "intermittent check and test".

When judging vacuum equipment faults, the "troubleshooting method" and the "comparison method" are commonly used, from simple to complex. "Outside first, then inside, assembly first, then parts, to avoid random disassembly."

The reason is that such people still lack systematic learning and training on vacuum equipment and related electrical and mechanical knowledge systems, lack understanding of the operating procedures and correlations of vacuum equipment, and blindly follow one step at a time.

When repairing vacuum equipment, correctly removing oil stains and impurities on the surface of parts is of great significance to improving the quality of repairs and extending the service life of the machinery. Due to careless cleaning of parts, unreasonable selection of cleaning agents and improper cleaning methods, early wear and corrosion damage of parts often occur in some maintenance units.
