Adsorption Dryer is another type of dryer used to get rid of water in compressed air. It achieves drying effect by "pressure change" (pressure swing adsorption principle). Because the moisture containing
capacity of air is inversely proportional to pressure, part of the
dried air decompresses to atmospheric pressure, this pressure changes
makes the
expanded air gets drier.Then let it pass through adsorption tower which
need regeneration, the drying regeneration air extract water, then take
the water out of adsorption tower. So adsorption dryer normally are of twin tower
construction. One tower dries the air from the compressor while the
desiccant in the other tower is being regenerated after the pressure in
the tower has been reduced to atmospheric pressure.
There are two types of adsorption dryers: heatless adsorption type, no internal or external
heaters are used, and heat adsorption dryer, which need a heater. Compared with Refrigerant Dryer, the advantage of adsorption dryer is its drying performance is beter, but its disadvantage is this kind of dryer consumes compressed air, which makes operation power consumption bigger.

From a functional point of view, the pest and disease survey statistics device can basically meet the requirements of modern agricultural and forestry pest survey and statistics work. It can not only set the classification subjects and types according to the pest and disease projects of various plants, but also indicate the collection time. Locations, plant names, and statistical methods, etc., color LCD screen can be viewed and edited information to ensure the smooth development of field work.
However, if the insect survey statistical device fails in the field, then it is more distressing for the staff. Therefore, the following analysis is made on several common failures that are strongly reflected by users, and a targeted solution is given. .
1. The pest survey statistic device cannot be turned on The pest survey statistic device cannot be turned on. It means that the instrument cannot work normally. However, this does not mean that the instrument is damaged. Because we know that the pest survey statistician needs to use batteries to provide energy for it, the most likely reason for the bug investigation and statistics analyzer to be turned on is that the battery power is insufficient or the battery contact points are dirty, resulting in poor contact and causing the battery. Can not supply power to the instrument normally, so for this situation, you can replace the battery or clean contact points, if you still can not boot after processing, then there may be instrument failure, you can contact the manufacturer to resolve after sale.
2. Diseases and insects survey statistics communication is not normal For further analysis and research, pest control survey statistics statistics data often need to be derived, and at this time the pest survey data communication is not normal, it will also affect the work. If the instrument appears this situation should first be to see if the battery is low, if it is to replace the battery, if not then check the data cable is connected, if the data cable is not connected, then connect the data cable.
3. Insect survey statistics screen display dimming and users reflect, in the process of using the pest survey statistics, found that the screen display darkens, after our analysis and testing found that this situation is due to low battery power If you encounter this situation, you only need to replace the battery.
Troubleshooting of common disease survey statistics
Pest control has always been a top priority in the field of agricultural production, and plant protection work has always been focused on prevention. Therefore, in order to effectively carry out pest prediction, forecasting, early warning, and research work, pest survey statistics are used to replace paper and pens in the past. The recording of the working methods of calculations can enable the staff to conduct pest surveys and statistics work in agriculture, forestry, quarantine and other fields more scientifically and rationally, and improve the accuracy of pest survey statistics.
