先前研究开发出的用于汽车空调的商用往复式压缩机的简化实验模型,用于使用应变仪测定吸气阀的位移和使用PIV技术(激光粒子图像速度测量学)来调查通过阀的排气速度分布。本文的重点在于吸气阀形状对降振的影响。首先,老式阀孔的尺寸和老式阀顶端的宽度发生变化,以及制造了七种新型阀来降低阀的振动。因此,人们发现新型阀中有一种阀对于降振最有效。其次,通过改变阀的材质和厚度,采用一种新型阀来调查固有频率对于降振的影响。最后,通过阀周围的流动分析结果来讨论新型阀降振的原因。新型阀的降振通过测定用于汽车空调的往复式压缩机中的阀的位移来证实。
A simplified experimental model of a commercial reciprocating compressor developed previously for automotive air conditioners was used to measure the displacement of the suction valve using a strain gauge and to investigate the exhaust through the valve using the PIV technique (Laser Particle Image Velocimetry) speed distribution. The focus of this article is on the effect of suction valve shape on vibration reduction. First, the size of the old-fashioned valve bore and the width of the old-style valve were changed, and seven new valves were made to reduce valve vibration. Therefore, it is found that the new valve has a valve for the most effective vibration reduction. Second, by changing the material and thickness of the valve, a new type of valve was used to investigate the effect of natural frequency on vibration reduction. Finally, the reasons for the new type of valve damping are discussed using flow analysis around the valve. The vibration reduction of the new valve is confirmed by measuring the displacement of the valve used in the reciprocating compressor of a car air conditioner.
