Abstract:
With the development of high parameter, automation technology, testing and measurement technology, advanced process technology and some related disciplines for the rotating machinery, which promote the research and application of monitoring technology of the spiral groove face seals, the seal system could make real-time response to the change of working parameter. This paper mainly focus on the seal system which is appropriate for the inflammable, explosive, corrosive and toxic substance working medium, and the system must require attaining ‘zero-leakage’, so real-time monitoring the status of seal system is particularly important. This paper proposes a new method to achieve the seal pressure control. Firstly, to get the maximum differential pressure of inlet and outlet which can ensure zero leakage of the seal system in different working parameters through the experiment and numerical simulation. Secondly, to adjust the pressure of feed pump in real time through adjustment of control system when the pressure of sealed medium （the pressure of end face outlet）changes. Consequently, the pressure of end face inlet is adjusted to make the differential pressure of inlet and outlet less than or equal to the maximum differential pressure which can ensure zero leakage of the seal system.
