Abstract:

The decrease of water ring pumpoutput will deteriorate the condenser vacuum, which directly affects the economy and safety of the unit operation. Ensuring the output stability of the water ring pump is of great significance for safety in production.It analyzes the reasons for the output decreaseof vacuum pump B in #14 unit and provides corresponding solution.Borescope detection and ZJ-821 disincrustant can greatly improved the heat transfer effect of the cooler in 14B vacuum pump, thereby restore the output of the water ring pump. The method for solving the anomaly of this device is typical and can be attributed to special solutions.
