干燥机的主要目的是用来除去压缩空气中的水分，用冷干机能除去90%以上的饱和水蒸气。如果冷水机后部管路仍有大量水分，就需要对冷干机进行检查。而如果干燥机内部换热器泄露，这会造成一部分压缩空气不经过蒸发器直接从干燥机出气口出去。
The main purpose of the dryer is to remove the moisture in the compressed air, with a cold and dry machine can remove more than 90% of saturated water vapor. If the rear part of the chiller still has a lot of water, it is necessary to check the cold and dry machine. And if the internal heat exchanger inside the dryer leaks, this will cause a portion of the compressed air to go directly from the dryer outlet without passing through the evaporator.
排水器是干燥机内的一个易损小部件，虽然很小但其实是一个重要的部件。干燥机要除水必须通过排水器排出机外，如果排水器堵塞或损坏不能正常排水，那冷干机就失去了除水功能，压缩空气中的水分会原封不动跑到后部管路。因此，倘若碰到除水效果不佳的情况，就应仔细检查排水器的工作状况。
The drain is a fragile part of the dryer, although it is small but it is an important part. Dryer to remove water must be discharged through the drainage machine, if the drain is blocked or damaged can not be properly drained, then the cold and dry machine lost the water removal function, compressed air in the water will be intact to the rear of the pipeline. Therefore, if you encounter the case of poor water removal, you should carefully check the working conditions of the drainage.
有行业人士表示，干燥机虽然种类多，但日常维护工作并不多，操作者切勿忽视。在维护过程中，操作者除了适时清洗冷凝器，另外就是经常检查排水器的工作情况，一有堵塞现象应及时清洗。如果是轻微堵塞，可以向排水器内倒入少许洗洁精，然后上下晃荡几次再清洗即可。如果堵塞比较严重，就需要把排水器进行分解清洗。若有不能清洗解决的排水器，专家建议应立即更换。
Industry insiders said that although the dryer more types, but the daily maintenance work is not much, the operator should not be ignored. In the maintenance process, the operator in addition to timely cleaning the condenser, the other is often check the work of the drainage device, a clogging phenomenon should be promptly cleaned. If it is slightly blocked, you can pour a little detergent into the drain, and then shake up and down several times can be cleaned. If the blockage is more serious, you need to drain the decomposition of cleaning. If there is a drainage that can not be cleaned, the expert advice should be replaced immediately.
