Description

Technical Field

[0001] The utility model relates to the technical field of air drying, in particular to an air drying structure for an air pump. Background Technique

[0002] In an air suspension system, the air pump plays a crucial role. It is responsible for transporting compressed air into the suspension airbag to adjust the height and support force of the vehicle.

[0003] In the existing air suspension system, the air pump usually only relies on a simple filtering device to remove moisture and impurities in the air. These devices often have limited effects. Especially in a humid or dusty environment, moisture and impurities in the air are likely to accumulate inside the suspension airbag, resulting in corrosion and blockage of the airbag and related components, affecting the system performance and service life. It is impossible to detect the humidity of the air in the drying structure in real time and know whether the drying standard is reached. Moreover, the position of the air drying structure on the air pump is fixed and cannot be adjusted in terms of up and down height, lacking flexibility. And the filter net cannot be disassembled, resulting in a lot of dust accumulating inside and being inconvenient to clean. Content of the Utility Model

Locking bolts are arranged on the mounting pieces, and the locking bolts are all threadedly connected with the first filtration chamber.

[0007] As a further scheme of the utility model: Two desiccant layers are installed inside the second filtration chamber. The desiccant layer is made of calcium chloride, and calcium chloride adsorbs moisture in the air to achieve the drying operation.

[0008] As a further scheme of the utility model: A HEPA filter is installed in the front part of the drying chamber. When the HEPA filter is started, the HEPA filter can further remove the remaining fine particles and the accumulated water droplets.
