摘要

通过对新型同步回转式压缩机滑片的运动及受力分析

建立了其动力学模型

分析推导了滑片上各点摩擦力随主轴转角的变化关系及滑片上摩擦功耗的大小.在该模型基础上

对一台排量为96 cm

/r的同步回转式压缩机样机的滑片所受的摩擦力及摩擦功耗进行了分析计算

并与相同规格的旋叶式压缩机进行比较.结果表明:同步回转式压缩机滑片摩擦功耗主要发生在滑片与转子滑槽之间

占滑片总摩擦功耗的88.5%; 样机的滑片摩擦功耗只有66.08 W

比同规格旋叶式压缩机的滑片总摩擦功耗降低85.1%; 样机的总摩擦功耗约为218 W

比同规格旋叶式压缩机降低53.8%.研究结果表明

同步回转式压缩机在摩擦功耗方面表现出明显优势.

Abstract

A dynamic model was established by analyzing the motion and the stress of the sliding vane for an innovative synchronal rotary compressor. The variation of the friction forces acting on the sliding vane with the rotation angle and the friction power loss of the sliding vane were deduced. On the basis of the dynamic model

the friction forces and the friction power loss of the sliding vane for a prototype with a capacity of 96 cm

/r were calculated and the calculation results were compared with a rotary vane compressor with the same capacity. The results show that the friction power loss between the sliding vane and the vane slot of the rotor is the main part of the vane friction power loss

i.e.

88.5% of the total. The vane friction power loss of the synchronal rotary comp

ressor prototype is 66.08 W and decreases by 85.1% compared with that of the rotary vane compressor. The total friction power loss of the prototype is about 218 W and decreases by 53.8% compared with that of the rotary vane compressor.
