|piston compressor/reciprocal compressor;[机]往复式压缩机;活塞式压缩机
往复式压缩机(reciprocating compressor)是一种通过活塞在气缸内往复运动实现气体压缩的机械装置,属于容积式压缩机的一种。其核心结构包括气缸、活塞、连杆、曲轴、进气阀和排气阀等部件。当活塞向气缸底部移动时,进气阀开启,低压气体进入气缸;活塞回程时,气体被压缩至设定压力后通过排气阀排出。
该设备的工作原理遵循理想气体定律($PV=nRT$),通过周期性容积变化实现能量转换。其典型压缩过程包含吸气、压缩、排气三个阶段,压力范围通常为0.7 MPa至40 MPa,适用于中小流量高压场景。热力学效率可通过等熵压缩公式计算: $$ eta = frac{T_2 - T1}{T{2s} - T1} $$ 其中$T{2s}$为等熵压缩终温。
工业领域主要应用于:
相较于离心式压缩机,往复式机型具备更高单级压缩比(可达4:1)和更宽工况适应性,但存在振动较大、维护周期短(每2000-8000小时需检修活塞环)的局限性。美国能源部数据显示,优化后的二级往复压缩机可比单级机型节能15%-20%。
reciprocating compressor 的中文译名为往复式压缩机或活塞式压缩机,是一种通过活塞在气缸内的往复运动实现气体压缩的机械设备。以下是详细解释:
如需进一步了解技术参数或具体型号,可参考机械工程手册或专业词典(如欧路词典)。
