Is the water content of the gas in the water lubricated air compressor high?

shanghai granklin group water lubricated air compressor factory products with high water content?

Water lubricated air compressor, since the use of water as a lubricant will certainly be rich in water vapor, then we need post-processing equipment to deal with the gas discharged from the water lubricated air compressor.

Refrigerated dryers, adsorption dryers and other dryer equipment, as well as filters, gas tanks, etc. can effectively eliminate water molecules in water vapor.

air compressor compressed air with water?

It is well known that moisture in the air is a good thing for some industries, but our air compressor does not like air with high moisture content-condensing water on pneumatic equipment will take away lubricating oil, resulting in equipment efficiency reduction or even damage;

accelerate the wear of valves in the pipeline, resulting in failure or misoperation of pneumatic control equipment; cause corrosion of pipelines and equipment. If water freezes at the low point of the pipeline, the pipeline still has the danger of bursting.

So, how to solve the problem of high water content in compressed air?

Analysis of several causes of compressed air with water and solutions:

(1) The water in the gas is mixed with the lubricating oil during the compression process, which will reduce the lubrication efficiency and increase the abrasion of the machine parts. It will not only cause poor sealing but also cause the lubricating oil to deteriorate and emulsify in the packing of the rubber circulating lubrication. Solution: Check the gas-water separator regularly, and discharge the condensed water in time if there is a blockage and other faults. If the gas-water separator is not drained in the summer when the air humidity is high, it should be checked and processed immediately.

(2) The air supply system contains water. When the temperature is lower than 0 degrees, the water will freeze on the inner wall of the air duct. Similarly, the pipe diameter will be reduced. What is more serious is that it will sometimes even cause individual pipelines to freeze completely and hinder work. Solution: For the phenomenon of icing on the inner wall of the air duct in the air supply system, the thin ice on the inner wall of the air duct will melt and evaporate into water due to the high temperature of the compressed air when the compressed air is discharged after the subsequent startup operation, and the water will blow out of the air duct with the air. For the phenomenon that the pipeline is completely frozen, we should check the air duct regularly, and do a good job of waterproof and rainproof when the screw air compressor is out of use. In the case of low temperature in winter, the air supply pipe is wrapped with thermal insulation material to protect the air pipe and prevent the inner wall of the air pipe from freezing.

(3) The adsorption material used in the adsorption dryer is activated alumina. If it is not tightly filled, it will rub and collide with each other under the impact of strong compressed air, resulting in pulverization. The pulverization will make the adsorbent gap larger and larger, and a large amount of compressed air will not be effectively treated through the gap, which will eventually lead to the failure of the dryer. This problem is reflected in the phenomenon of large amount of liquid water and slurry in the dust removal filter. Solution: fill as closely as possible when filling activated alumina, check and supplement after a period of time. Replace the oil separator core and the rear oil removal filter element on time to ensure complete oil and gas separation of the air compressor and good oil removal of the rear oil removal filter. In addition, the super coolant in the unit shall not be excessive.

(4) The air humidity changes greatly, and the drainage frequency and drainage time of each timing drain valve are not adjusted in time, which can make more and more water in each filter, and these water can be brought into the compressed air again. Solution: the drainage frequency and time of the timing drain valve can be set according to the air humidity and experience. If the air humidity is high, the drainage frequency should be increased, and the drainage time should be increased at the same time. The adjustment standard is to observe that the accumulated water can be drained without discharging compressed air each time. The method is always thought out by people. It is an inevitable fact that the air contains water. How to solve them correctly and simply is the wisdom of our air compressor practitioners.
