Research On Thermal Energy And Dynamic Performance Of Frequency Conversion Operating Mode Piston Compressor

The compressor works with 70% shoulder undulates in 97% time, in order to guarantee a high operating efficiency, the frequency conversion velocity modulation has taken an adjustment way. If conventional compressor carry on the frequency conversion velocity modulation, its operating performance can change and appear some phenomenon and problems .And its frequency control scope is unknown. This article takes 4L-20/8 compressor as an example .First analyzed thermal energy and power change of the conventional compressor using the frequency conversion adjustment, then established mathematical model using simulink and adams .The result recovered that divulges needs to seal; the cooling water volume adjustment for heat needs to change quantity; and need to avoid long time low frequency movement to avoid efficiency reducing and so on .It has proposed the improvement of fly wheel, measures used for avoiding pipe network resonating and so on. Finally determined the lower frequency limit by evaluating the thermal and dynamic factors .
