Abstract
In response to the excessive vibration of the inlet pipe joint of the refrigeration screw compressor,resonance factors were excluded through vibration detection and modal analysis.Using numerical simulation methods to analyze the flow field characteristics of the inlet oil passage,it is found that liquid pulsation is the main cause of vibration exceeding the standard,and a plan to optimize the structure of the inlet oil passage is proposed.The flow field characteristics after adopting the vibration reduction scheme show that the maximum flow velocity of the oil system decreased by 30.2％,the pressure unevenness decreased by 46.1％,and the maximum turbulence energy decreased by 82.4％.After vibration control,the root mean square of vibration velocity at the inlet pipe joint under several operating conditions was tested and found to be below the threshold of 5 mm/s specified in GB/T 19410.The phenomenon of excessive vibration has been effectively controlled,and the operation of the compressor is quieter and more stable.关键词
