Use of capillary in cold water machine

东星制冷专业生产各类制冷设备，包括层析冷柜,冻干机，冷水机，超低温冰箱，恒温槽等，这些制冷设备中，都会使用到毛细管。毛细管是制冷系统中的制冷剂流量的控制元件。在安装与及使用过程中，都要非常小心。不能把全部毛细管都置于蒸发器附近，也不能把它放在普通汽液热交换器的液管之中。如果错误布置，过充量的制冷剂进入毛细管，会影响支配热交换器中高，低压侧的传热关系，从而导致冷却系统运行不稳定，使机器无法运行。因为吸气管中带液时毛细管前制冷剂液体过冷增强，使得毛细管通液能力变大，使得冷凝器中液体积存过少。采用毛细管的装置停机后压力系统压力逐渐平衡再次启动时压缩机无压差负荷，如果系统内压力不足，或者压力平衡不能及时实验，会导致电机不能胜任带载启动，烧毁机器。

East Star refrigeration professional production of various kinds of refrigeration equipment, including chromatography freezer and freeze dry machine, cold water machine, ultra low temperature freezer, thermostat bath, these refrigeration equipments will use to the capillary. Capillary is the control element of refrigerant flow in refrigeration system. In the installation and use of the process, should be very careful. Not all capillary tubes are placed near the evaporator, nor can it be placed in the liquid tube of the ordinary steam liquid heat exchanger. If the wrong arrangement, the amount of refrigerant into the capillary, will affect the heat exchanger in the high and low pressure side of the heat transfer relationship, which led to the operation of the cooling system is not stable, so that the machine can not run. Because in the suction pipe with liquid capillary liquid refrigerant supercooling enhancement, the capillary liquid capacity becomes larger, making the condenser liquid accumulation too little. The capillary device after the shutdown system pressure balance gradually start again when the compressor without differential pressure load, if the system pressure is insufficient, or pressure balance can not be timely experiment will lead to motor can not be competent load startup, the machine to burn.

毛细管内径范围大约在0.2~2.0mm，又细又长，非常容易被堵塞。因此，必须严格的保证制冷设备的清洁度，给毛细管装置精滤网，避免毛细管出现脏堵现象。另外，维修毛细管的互换性差装置时，不过迫不得已的情况，不要随意跟换毛细管。

The inner diameter of the capillary is in the range of 0.2~2.0mm, which is very thin and long, so it is very easy to be blocked. Therefore, it is necessary to strictly ensure the cleanliness of the refrigeration equipment, to the capillary device fine filter, to avoid clogging capillary phenomenon. In addition, the maintenance of capillary interchangeability device, but compelling circumstances, do not arbitrarily change with the capillary.
