Are you looking forward to investing in a desiccant air dryer? If so, it makes that you have a clear insight into how it operates. The desiccant compressed air dryer dries compressed air as per the principles of variable pressure desiccant. Under certain pressure, the compressed air flows through the absorbent bed from bottom to top.
It is worth mentioning that desiccant air dryers consist of two pressure vessels, which are both filled with desiccant and are alternatively operated via switch-over. The wet compressed air flows through a vessel, under high pressure and low temperature, while the moisture is thoroughly removed by the desiccant, so the compressed air will be dry.
So, how do you go about installing the desiccant air dryer? Well, the user pours the concrete foundation according to the size of the equipment and needs the ground screws to fasten, the equipment shall be placed in a ventilated place indoors.
When installing your desiccant air dryer, be sure to pay close attention to the versatility of the barrel. The equipment shall be fastened firmly, and shall be fastened again after a period of use. As for the pipeline, you need to install it as straight as possible. And this is easy to see considering many elbows will cause some loss to the flow and pressure of the equipment.
To ensure safety, non-safety voltage electrical parts, etc., should be effectively grounded. Grounding requirements are as specified. When it comes to the pipe height, it must be lower than the outlet height of the equipment. Otherwise, it will cause part of the liquid back flow and affect the regeneration effect. It is important to prevent rainwater and so on from entering.
Keep in mind the desiccant air dryer should be used in the room that will no danger of explosion, with no media that may cause corrode the metal. As the pneumatic working pressure of the pneumatic shut-off valve is 0.3-0.5Mpa, the pressure gauge indication on the filtering pressure reducing valve should be checked frequently to prevent damage to the cylinder by over pressure.
As we conclude, you need to pay attention to the maintenance of the safety valve. The two desiccant cylinders should be inspected regularly according to the pressure vessel testing procedures. Manual drainage at least 1-2 times per shift. Of course, there is a lot more you should know about the desiccant air dryer than what is included in this quick guide.
