Abstract: Steam turbine unit is the key equipment in refinery enterprises which plays an important role in the process of production. The static test is the final test in safety guarantee before the start-up of the steam turbine unit, and the establishment of the quick closing oil pressure is the key to the smooth progress of the static test. This paper analyzes the oil circuit diagram of quick closing components of some equipment in certain company. Combining with the related problems encountered in the practical management of equipment over the past few years, it puts forward solutions to the problems, and summarizes the solutions to some typical problems systematically, which is helpful to promote the improvement of equipment management.

Key words: steam turbine, quick closing, oil pressure
