Abstract
In order to ensure the compatibility and balance of the low friction and small leakage of mechanical seal, a kind of friction state recognition of mechanical seal face dependent on adaptive neuro fuzzy (hereinafter referred to as ANFA for short) is put forward. In this algorithm, the variable neighborhood algorithm is combined with the PM mechanical seal face friction state recognition, which has overcome the defects that are existing in the traditional mechanical seal face frictional state recognition. Finally, simulation comparison is carried out on the proposed algorithm and the VNM algorithm, which has verified that the algorithm put forward in this paper can quickly identify the friction state of the mechanical seal face in the working process.
