干燥機的性能如何穩(wěn)定？

隨著現(xiàn)代工業(yè)的不斷發(fā)展，對壓縮空氣質(zhì)量的要求也越來越高，壓縮空氣的質(zhì)量主要由壓力露點決定，露點值越低，壓縮空氣質(zhì)量越好。在干燥機使用的時候，通常因為一些操作問題對機體造成損害，隨著時間的推移，一些平日不注意的問題就會導致干燥機的性能大大降低。由于不同的行業(yè)生產(chǎn)工藝存在差異化，對壓縮空氣的露點要求也不一樣。其實多數(shù)企業(yè)并不知道壓縮空氣品質(zhì)不良會給生產(chǎn)帶來巨大的危害，多數(shù)生產(chǎn)企業(yè)依然還是在使用冷凍式干燥機，壓力露點普遍在10℃左右，并不能滿足生產(chǎn)所需，

With the continuous development of modern industry, the requirements for the quality of compressed air are higher and higher. The quality of compressed air is mainly determined by the pressure dew point. The lower the dew point value, the better the quality of compressed air. In the use of the dryer, usually because of some operational problems caused damage to the body, with the passage of time, some problems that are not paid attention to on weekdays will lead to the performance of the dryer greatly reduced. Due to the difference of production process in different industries, the dew point requirements of compressed air are also different. In fact, most enterprises do not know that the poor quality of compressed air will bring great harm to the production. Most of the production enterprises still use the frozen dryer, and the pressure dew point is generally around 10 ℃, which can not meet the production needs,

我們使用的冷凍式干燥機就是根據(jù)濕空氣的物理性質(zhì)，利用制冷技術將壓縮空氣強制冷卻到要求的露點溫度以下，從而將其中所含的水蒸汽油霧冷凝成液滴，由自動排水器排出機外。而實際上冷干機能達到企業(yè)產(chǎn)品壓縮空氣行業(yè)標準的卻少之又少，而導致達不到標準的原因之一就是冷媒的填充問題。

According to the physical properties of the wet air, we use refrigeration technology to force the compressed air to be below the required dew point temperature, so as to condense the water vapor and oil mist contained in it into droplets, which are discharged from the machine by the automatic drainer. But in fact, the cold dry function to the enterprise product compressed air industry standard is very few, and one of the reasons for not reaching the standard is the refrigerant filling problem.

冷媒灌注過少，冷干機會出現(xiàn)這些現(xiàn)象：

If the refrigerant is too little, the phenomenon of cold drying may appear

1、蒸發(fā)壓力、冷凝壓力都比正常運轉低，但空氣露點卻降不下，壓縮機外殼發(fā)燙。而冷媒灌注過多，冷干機則會出現(xiàn)：

1. Evaporation pressure and condensation pressure are lower than normal operation, but the air dew point can not be reduced, and the compressor shell is hot. However, if the refrigerant is poured too much, the cold dryer will appear:

2、由于冷媒液體存積于冷凝器，使冷凝面積減小，導致冷凝壓力升高，嚴重時引起高壓跳閘;

2. As the refrigerant liquid accumulates in the condenser, the condensing area is reduced, which leads to the increase of condensing pressure and high-pressure trip in serious cases;

3、制冷壓縮機負荷增高，起動困難;

3. The load of refrigeration compressor is increased and it is difficult to start;

4、制冷劑在蒸發(fā)器中未能全部汽化，使?jié)裾魵膺M入壓縮機，有“液壓縮”危險;

4. If the refrigerant fails to vaporize completely in the evaporator, the wet steam will enter into the compressor and there is a danger of "liquid compression";

5、由于冷凝壓力升高，使壓縮機制冷量減少，空氣露點上升。

5. Due to the increase of condensation pressure, the cooling capacity of compressor decreases and the dew point of air rises.

因此冷媒的填充并不容易，沒有直觀的填充顯示，則會讓填充的難度更大,干燥機的模芯填充物為專用分子篩，分子篩的篩體式分散對流設計，合理分配氣源，吸附死角，有效利用所有的吸附劑，既減少了吸附劑的填充量，還化的發(fā)揮了分子篩的吸附作用。保持干燥機的性能穩(wěn)定，對干燥機做好檢查，次操作時一定要注意，避免損傷機體，所以應該為干燥機做定期保養(yǎng)。

Therefore, it is not easy to fill the refrigerant. If there is no intuitive filling display, it will make the filling more difficult. The mold core of the dryer is filled with special molecular sieve. The sieve type dispersion convection design of molecular sieve can reasonably distribute the gas source, eliminate the dead angle of adsorption, and effectively use all the adsorbents, which not only reduces the filling amount of adsorbent, but also maximizes the adsorption effect of molecular sieve. Keep the performance of the dryer stable, do a good job on the dryer inspection, the first operation must pay attention to avoid damage to the body, so should do regular maintenance for the dryer.
