空压机排气中有水的原因以及解决措施？

对于压缩空气系统来说，压缩是其目的，而冷却自压缩后开始贯穿始终空压机工作时，由于气体被压缩释放大量的热，压缩机头的内部温度是非常高的（100℃左右）吸入的自然空气中的水份，会在空压机的压缩过程时形成水蒸气。

For the compressed air system, compression is its purpose. When the air compressor works, the internal temperature of the compressor head is very high (about 100 ℃) because the gas is compressed to release a lot of heat. The water in the natural air inhaled will form water vapor during the compression process of the air compressor.

随压缩空气排出一般在空压机机组内配有空气冷却器，对预备排出空压机的压缩空气强制降温，目的是利用降温冷凝作用来去除一部分压缩空气中的水这还是空压机本身降温排水功能健全的情况下，否则，压缩空气和水一并向后端管路流去即便空压机本体排水功能正常

With the discharge of compressed air, the air cooler is generally equipped in the air compressor unit to force the compressed air to be discharged from the air compressor to cool down. The purpose is to remove part of the water in the compressed air by cooling and condensation. This is still under the condition that the cooling and drainage function of the air compressor itself is sound. Otherwise, the compressed air and water will flow to the rear pipe together, even though the drainage function of the air compressor body normal

空压机出口没有液态水，但排出的压缩空气仍然是饱和状态、只需一点点降温，压缩空气中还是会凝析出液态水南方的“回南天”很直观的说明了水的形成，温暖潮湿的空气遇到较低温度的物体表面，比如地板、墙壁等，就会在其表面凝析出水珠

There is no liquid water at the outlet of the air compressor, but the discharged compressed air is still saturated and needs only a little cooling. Liquid water will still condense out of the compressed air. The "return to the South" in the South directly shows the formation of water. When warm and humid air meets the surface of objects with lower temperature, such as floors and walls, it will condense out water droplets on the surface

在压缩空气系统内，接空压机的出口有各种管道、储气罐、过滤器等，这些物体的温度都比排出的压缩空气要低（一般空压机的排气温度是环境温度的10℃以上），这就必然的凝析出大量的水尤其是储气罐中

In the compressed air system, there are various pipes, air tanks, filters, etc. at the outlet of the air compressor. The temperature of these objects is lower than that of the discharged compressed air (generally, the exhaust temperature of the air compressor is above 10 ℃ of the ambient temperature), which inevitably condenses out a large amount of water, especially in the air tank

当压缩空气通过储气罐时，高速的气流撞击到储气罐壁使其产生汇流，在储气罐内使温度快速下降，使大量的水蒸气液化，形成冷凝水。如果赶上潮湿的天气（吸入的空气本身湿度大）或者冬季（环境温度低，与空压机排气的温差更大），还会形成更多的冷凝水

When the compressed air passes through the gas tank, the high-speed air stream impacts the gas tank wall to make it converge, which makes the temperature drop rapidly in the gas tank, liquefying a large amount of water vapor and forming condensed water. If you catch up with the humid weather (the humidity of the inhaled air itself is high) or winter (the ambient temperature is low, and the temperature difference with the air compressor exhaust is greater), more condensed water will be formed

所以通常储气罐的排水是几乎所有空压机业者反复强调的、储气罐的进出口管的“下进上出”方式也是考虑储气罐底部可能储水的情况，避免液态水随气流向后端流动

So usually, the drainage of the air tank is repeatedly emphasized by almost all air compressor operators, and the "down in and up out" mode of the inlet and outlet pipes of the air tank also considers the possible water storage at the bottom of the air tank, so as to avoid the liquid water flowing with the gas to the back end

如何去除空压机排气中的水？

How to remove water from air compressor exhaust?

完全的去除压缩空气中的水是不可能而且毫无必要的，我们只要达到我们要的干燥度即可常对于绝大多数一般的压缩空气用途，比如驱动气缸、吹扫、气动工具等，只要在当前环境温度下用气端不含有液态水即可而对于一些要求较高的场合，比如喷涂、纺织、电子、食品药品等，则各自有对压缩空气中的水分的要求

It is impossible and unnecessary to completely remove the water in the compressed air. We only need to achieve the dryness we want. For most common uses of compressed air, such as driving cylinder, purging, pneumatic tools, etc., as long as there is no liquid water at the air end under the current ambient temperature, but for some occasions with higher requirements, such as spraying, textile, electronics, etc , food and drugs, respectively, have requirements for moisture in compressed air
