冷干机是冷冻式干燥机的简称,是压缩空气系统中的干燥设备;冷干机价格低廉但非常重要,所以了解冷干机的技术参数及应用效果有助于企业做出良好的采购预估。
 
The cold dryer is the abbreviation of the freeze dryer, which is the drying equipment in the compressed air system. The price of the cold dryer is low but very important, so understanding the technical parameters and application effect of the cold dryer is helpful for the enterprise to make a good purchase estimate.

The cold dryer is the abbreviation of the freeze dryer, which is the drying equipment in the compressed air system. The price of the cold dryer is low but very important, so understanding the technical parameters and application effect of the cold dryer is helpful for the enterprise to make a good purchase estimate.
 
1.压力露点(干燥效果单位)
 
1. Pressure dew point (drying effect unit)
 
冷干机可以将压缩空气中90%左右的水份都分离掉,通过冷干机处理过后的压缩空气一般可以达到3°C-10°C的压力露点;
 
The cold dryer can separate about 90% of the water in the compressed air, and the compressed air treated by the cold dryer can generally reach a pressure dew point of 3 ° C-10 ° C;
 
这就是冷干机最重要的一项技术参数:压力露点。
 
This is the most important technical parameter of the cold dryer: pressure dew point.
 
 
压力露点是压缩空气干燥度的单位,如果达不到某个特定的值,就无法满足某项生产工艺要求(每个行业都有其压缩空气干燥度标准)。
 
Pressure dew point is the unit of compressed air dryness. If it can not reach a specific value, it can not meet the requirements of a production process (each industry has its compressed air dryness standard).
 
2.处理流量和处理压力
 
2. Treatment flow and pressure
 
所以,选型的最终目的都是:通过冷干机处理的压缩空气能够满足生产需求。
 
Therefore, the final purpose of selection is: the compressed air processed by the cold dryer can meet the production demand.
那么就涉及到另一项技术参数:冷干机的处理流量和处理压力;
 
Then it involves another technical parameter: the treatment flow and pressure of the cold dryer;
 
比如某车间用气量为5立方每分钟(m3/min),末端压力0.7公斤(mPa),压缩空气主要用于贴片机和零件吹扫。
 
For example, the air consumption of a workshop is 5 cubic meters per minute (m3 / min), and the end pressure is 0.7 kg (MPA). The compressed air is mainly used for chip mounter and parts purging.
 
大多数冷干机厂家会建议配置6-8立方处理流量的冷干机,而不少用户都会因为省钱选择5立方的冷干机。这并不是开玩笑,这是普遍存在的现象,我们每年夏天都会接到数不胜数的客户电话,诉苦当初没有买大一点的冷干机。
 
Most cold dryer manufacturers will recommend to configure 6-8 cubic meters of cold dryer, and many users will choose 5 cubic meters of cold dryer because of saving money. It's not a joke. It's a common phenomenon. Every summer, we get countless calls from customers complaining that they didn't buy a bigger dryer.
 
 
那么为什么冷干机厂家要这样建议?
 
So why do cold dryer manufacturers suggest this?
 
因为高温天气的存在,以及有时候需要大负荷运转空压机的情况,都会导致冷干机负载,而负载带来的结果就是后端大量出现液态水,甚至停机停工。
 
Because of the existence of high temperature weather, and sometimes the need to operate the air compressor with a large load, will lead to the load of the cold dryer, and the result of the load is a large number of liquid water at the rear end, or even shutdown.
 
经历过这种情况的用户,基本上以后都不会在冷干机的选型上省钱了。
 
Users who have experienced this situation will not save money on the selection of cold dryer in the future.
 
冷干机按照处理压力的不同分为两种:常压冷干机、高压冷干机;
 
According to the different treatment pressure, the cold dryer can be divided into two types: normal pressure cold dryer and high pressure cold dryer;
 
压缩空气压力大于12公斤(1.2mPa),就需要使用高压机型。
 
If the compressed air pressure is more than 12 kg (1.2 MPa), a high-pressure machine is needed.
 
3.环境温度、进气温度
 
3. Ambient temperature, air inlet temperature
 
空压站的环境温度和压缩空气进入冷干机的温度同样是影响冷干机干燥效果的重要参数;
 
The ambient temperature of air compressor station and the temperature of compressed air entering the cold dryer are also important parameters affecting the drying effect of the cold dryer;
 
一般要求是环境温度小于40°C,进气温度小于38°C。
 
The general requirements are that the ambient temperature is less than 40 ° C and the air inlet temperature is less than 38 ° C.
 
环境温度过高会导致冷媒散热不完全,进气温度过高会导致含水量过高以及降温效果变差;
 
Too high ambient temperature will lead to incomplete cooling of refrigerant, too high intake temperature will lead to too high water content and poor cooling effect;
 
进而致使干燥效果大大下降。
 
Then the drying effect is greatly reduced.
 
以上便是冷干机最关键的几类技术参数,是压缩空气用户在冷干机选型中绝对不能避开的几点技术参数。
 
The above are the most critical technical parameters of the cold dryer, which can not be avoided by compressed air users in the selection of the cold dryer.
