| Abstract: | Aiming at the processing requirements of valve parts used in coal mine hydraulic supports,the problems of settlement stability and preparation efficiency in the mechanical preparation and storage of magnetorheological polishing fluids(MPF) were preliminarily solved,and a new process for preparing MPF by ultrasound was proposed. Based on the response surface method,the effects of ultrasonic power,immersion depth of luffing rod and ultrasonic time on the sedimentation stability of MPF were studied.The sedimentation rate of MPF under traditional mechanical stirring process and ultrasonic preparation process were compared experimentally,and decline rate of the outer surface roughness of the hydraulic spool. |
| Keywords: | coal mine hydraulic spool MPF sedimentation rate ultrasonic dispersion response surface method |
