双回转式压缩机的动力计算及动力特性

DYNAMICAL COMPUTATION AND DYNAMICAL PROPERTY OF THE DOUBLE ROTARY COMPRESSOR

与往复活塞式压缩机相比,双回转式压缩机具有三大动力特性:1)任一活塞的气体推力方向总是沿缸孔轴心线指向吸气段;2)活塞不存在往复运动惯性力;3)活塞尽管作往复移动,但就联体活塞而言,只存在单向摩擦力.鉴于此,根据双回转式压缩机的结构原理。

Contracting with reciprocating piston compressor,the double rotary compressor has three main dynamical properties:1)The air thrust direction of every piston always points towards the suction area around the cylinder hole axis.2)The piston hasn't the reciprocating inertial force.3)Though the piston does reciprocating motion,to conjunct body piston,it only has friction on one way.In view of the above mentioned facts,accounting to construct principal of the double rotary compressor,the dynamical computational formula of the compressor is put out.
