Engine/Valves & Cocks/752901 CONTROL PRESSURE WITH, FURTHER DETAIL

中文品名：压力控制器

A pressure control contains a single-pole changeover switch.  The position of the contacts depends on the set scale value and the pressure in the inlet connection.  This control is used as protection against too low a suction pressure or too high a discharge pressure on compressors for refrigeration and air conditioning plants.  Also used for starting and stopping refrigeration compressors and condenser fans.

压力控制包含一个单极转换开关。触点的位置取决于设置的比例值和入口连接中的压力。这种控制用于防止制冷和空调设备的压缩机吸气压力过低或排气压力过高。也用于启动和停止制冷压缩机和冷凝器风扇。
