摘要:     压缩机是制冷系统的心脏,它从吸气管吸入低温低压的制冷剂气体,通过电机运转带动活塞对其进行压缩后,向排气管排出高温高压的制冷剂气体,为制冷循环提供动力,从而实现压缩→冷凝→膨胀→蒸发(吸热)的制冷循环。压缩机一般由壳体、电动机、缸体、活塞、控制设备(启动器和热保护器)及冷却系统组成。启动器基本上有两种,即重锤式和PTC式。其中后者较为先进。冷却方式有油冷和自然冷却两种。

     1.概述 
      
     压缩机是制冷系统的心脏,它从吸气管吸入低温低压的制冷剂气体,通过电机运转带动活塞对其进行压缩后,向排气管排出高温高压的制冷剂气体,为制冷循环提供动力,从而实现压缩→冷凝→膨胀→蒸发(吸热)的制冷循环。压缩机一般由壳体、电动机、缸体、活塞、控制设备(启动器和热保护器)及冷却系统组成。启动器基本上有两种,即重锤式和PTC式。其中后者较为先进。冷却方式有油冷和自然冷却两种。 
      
     一般家用冰箱和空调器的压缩机是以单相交流电作为电源,它们的结构原理基本相同。冰箱压缩机功率较小,通常在250W以下。而空调器压缩机功率通常在230-900W之间。两者使用的致冷剂有所不同。 
      
     2.生产制造方法 
      
     压缩机是以流水线方式生产的。在机械加工车间(包括铸造)制造出缸体、活塞(转轴)、阀片、连杆、曲轴、端盖等零部件;在电机车间组装出转子、定子;在冲压车间制造出壳体等。然后在总装车间进行装配、焊接、清洗烘干,最后经检验合格包装出厂。大多数压缩机制造厂不生产启动器和热保护器,而是根据需要从市场采购。 
      
     3.种类 
      
     目前家用冰箱和空调器压缩机都是容积式,其中又可分为往复式和旋转式。往复式压缩机使用的是活塞、曲柄、连杆机构或活塞、曲柄、滑管机构,旋转式使用的是转轴曲轴机构。
