空壓機排氣中有水的原因以及解決措施？

對于壓縮空氣系統來(lái)說(shuō)，壓縮是其目的，而冷卻自壓縮后開(kāi)始貫穿始終空壓機工作時(shí)，由于氣體被壓縮釋放大量的熱，壓縮機頭的內部溫度是非常高的（100℃左右）吸入的自然空氣中的水份，會(huì )在空壓機的壓縮過(guò)程時(shí)形成水蒸氣。

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.

隨壓縮空氣排出一般在空壓機機組內配有空氣冷卻器，對預備排出空壓機的壓縮空氣強制降溫，目的是利用降溫冷凝作用來(lái)去除一部分壓縮空氣中的水這還是空壓機本身降溫排水功能健全的情況下，否則，壓縮空氣和水一并向后端管路流去即便空壓機本體排水功能正常

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

空壓機出口沒(méi)有液態(tài)水，但排出的壓縮空氣仍然是飽和狀態(tài)、只需一點(diǎn)點(diǎn)降溫，壓縮空氣中還是會(huì )凝析出液態(tài)水南方的“回南天”很直觀(guān)的說(shuō)明了水的形成，溫暖潮濕的空氣遇到較低溫度的物體表面，比如地板、墻壁等，就會(huì )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

在壓縮空氣系統內，接空壓機的出口有各種管道、儲氣罐、過(guò)濾器等，這些物體的溫度都比排出的壓縮空氣要低（一般空壓機的排氣溫度是環(huán)境溫度的10℃以上），這就必然的凝析出大量的水尤其是儲氣罐中

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

當壓縮空氣通過(guò)儲氣罐時(shí)，高速的氣流撞擊到儲氣罐壁使其產(chǎn)生匯流，在儲氣罐內使溫度快速下降，使大量的水蒸氣液化，形成冷凝水。如果趕上潮濕的天氣（吸入的空氣本身濕度大）或者冬季（環(huán)境溫度低，與空壓機排氣的溫差更大），還會(huì )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

所以通常儲氣罐的排水是幾乎所有空壓機業(yè)者反復強調的、儲氣罐的進(jìn)出口管的“下進(jìn)上出”方式也是考慮儲氣罐底部可能儲水的情況，避免液態(tài)水隨氣流向后端流動(dòng)

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

如何去除空壓機排氣中的水？

How to remove water from air compressor exhaust?

完全的去除壓縮空氣中的水是不可能而且毫無(wú)必要的，我們只要達到我們要的干燥度即可常對于絕大多數一般的壓縮空氣用途，比如驅動(dòng)氣缸、吹掃、氣動(dòng)工具等，只要在當前環(huán)境溫度下用氣端不含有液態(tài)水即可而對于一些要求較高的場(chǎng)合，比如噴涂、紡織、電子、食品藥品等，則各自有對壓縮空氣中的水分的要求

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
